Introduction, Construction, Components, and Recycling Value
Introduction
Read the full silkscreen before treating this as a retail P8H61-M PRO. The “CM6630/DP_MB” suffix and CM6630-8 BIOS identifier point to an ASUS OEM variant; confirm the board revision and rear I/O before applying retail specifications
This board is a desktop motherboard, not a laptop motherboard. Its physical construction uses a desktop Intel LGA socket with metal load plate and retention lever, full-size DDR3 DIMM sockets, desktop PCI Express slots, SATA connectors, ATX power connectors, desktop rear I/O connectors, and a rectangular Micro-ATX-style PCB. A laptop motherboard would normally have SO-DIMM memory slots, flat-flex display connectors, battery connectors, notebook power circuitry, and an irregular chassis-specific board outline. The P8H61-M PRO/CM6630/DP_MB has none of those notebook-board features.
The model belongs to the ASUS P8H61-M PRO / CM6630 OEM family. The board marking identifies it as P8H61-M PRO/CM6630/DP_MB, while ASUS support references list BIOS files named P8H61-M-PRO-ASUS-CM6630-8, confirming the connection between the P8H61-M PRO board family and ASUS CM6630 desktop systems. The same exact variant is also listed in board-reference sources as ASUS P8H61-M PRO/CM6630-8/DP_MB, based on the Intel H61 chipset.
From a recycling viewpoint, the motherboard contains recoverable electronic value, but it is not a premium-grade board. Its value comes from the assumed installed LGA1155 CPU, LGA1155 socket contacts, DDR3 memory-slot contacts, PCI Express slot contacts, Intel H61 chipset package, Realtek audio and LAN sections, BIOS flash, Super I/O / monitoring controller, SATA connectors, USB and rear I/O connectors, voltage-regulation components, copper-bearing PCB layers, solder, nickel-plated connector shells, MLCCs, and limited gold-bearing contact surfaces. Under the Ohata internal board-value sorting method, this construction is classified as D Grade Board Scrap, assuming the CPU is installed and the board remains complete.
Common Computer Brand and Practical Use
This motherboard is normally associated with ASUS desktop computers, especially the ASUS CM6630 / CM6630-8 desktop family and related OEM service configurations. The BIOS reference for the ASUS CM6630 platform specifically names P8H61-M-PRO-ASUS-CM6630-8, which confirms the board’s ASUS desktop-system application.
Unlike a retail gaming motherboard sold in a standard box for any custom builder, this is primarily an OEM desktop motherboard. It was designed for a specific ASUS desktop chassis and BIOS environment. However, it can still be used by computer hobbyists for repair, bench testing, and personal desktop builds if the user verifies CPU compatibility, BIOS version, front-panel connector wiring, case mounting, power-supply connectors, cooling clearance, display-output needs, and expansion-card compatibility.
A hobbyist may use this board with a compatible LGA1155 processor, DDR3 memory, SATA storage, an ATX-compatible power supply, and a discrete PCI Express graphics card if needed. Because it is an OEM board, the builder should not assume that all retail ASUS P8H61-M PRO BIOS files, front-panel pinouts, or upgrade behaviors are identical to every CM6630/DP_MB revision. For recycling, these compatibility concerns do not affect the scrap grade; the board is graded by physical construction, component completeness, CPU presence, and recoverable material content.
CPU Socket and CPU Package Size
The CPU socket is Intel LGA1155, also called Socket H2. P8H61-M PRO system-board references list LGA 1155 as the CPU socket type and list Intel Celeron, Pentium, Core i3, Core i5, and Core i7 processor families as supported CPU classes.
LGA means land grid array. On an LGA motherboard, the socket contains delicate spring contacts, while the processor underside has flat conductive lands. The socket uses a metal load plate and lever to clamp the CPU into contact with the socket pins. This physical design is important for scrap classification because the Ohata Board Grade Class specifically places i-series motherboards where the CPU socket has a metal cover and lever into D Grade.
The compatible CPU package size is 37.5 mm × 37.5 mm. Intel’s official Core i5-2500 processor specification lists LGA1155 as the socket and 37.5 mm × 37.5 mm as the package size. This CPU-size confirmation is required because the motherboard must not be confused with AMD AM-series PGA boards, Intel LGA775 boards, LGA1156 boards, LGA1366 boards, mobile notebook boards, or Apple logic boards.
For the purpose of this recycling guide, the board is evaluated under the required assumption that a compatible CPU is installed. A CPU-installed board is more valuable than the same motherboard without CPU. The CPU adds silicon, package substrate, internal metal layers, contact lands, heat-spreader metal, and precious-metal-bearing semiconductor materials. If the CPU is missing, the board remains recyclable, but its buying value decreases. If the LGA1155 socket is damaged or removed, the value reduction is greater because the socket contact field is also lost or compromised.
Intel H61 Chipset Platform
The motherboard uses the Intel H61 Express chipset. The exact P8H61-M PRO/CM6630-8/DP_MB reference identifies the board as based on the Intel H61 chipset, and P8H61-M PRO technical specifications list Intel H61 Express as the chipset.
The H61 chipset is a cost-efficient Intel desktop platform controller hub for LGA1155 systems. It was widely used in consumer desktops, office PCs, and OEM systems. Many functions that once required separate chips are consolidated into the CPU and chipset on this generation. The CPU integrates the memory controller, PCI Express graphics lanes, and integrated graphics engine on supported processor models, while the H61 chipset handles platform I/O such as SATA, USB, PCI Express support lanes, and management functions.
This integrated design improves computer performance and lowers production cost, but it also reduces the number of discrete support chips and lowers the board’s recoverable precious-metal density compared with older, more component-rich desktop boards. That is one reason this board is classified as D Grade rather than C Grade, B Grade, A Grade, or A+ Grade under the Ohata internal method. The detailed D Grade reference describes later-generation Intel desktop boards and integrated desktop motherboards as lower-value computer boards because they emphasize cost-efficient construction and contain lower recoverable precious-metal concentration than higher grades.
Graphics Output and Display Function
The board provides motherboard display output through rear video connectors. P8H61-M PRO technical specifications list DVI, D-Sub, and HDMI output support in the reference layout. The board itself does not function as a separate graphics card. On this platform, display output depends on the installed LGA1155 CPU’s integrated graphics capability and the motherboard’s display routing.
If a discrete graphics card is installed in the PCI Express x16 slot, that graphics card should be removed and sorted separately. A graphics card has its own PCB, GPU, memory chips, cooling assembly, and PCI Express gold fingers. The P8H61-M PRO/CM6630/DP_MB motherboard remains desktop motherboard scrap, not graphics-card scrap.
Memory Subsystem
The board has two full-size DDR3 DIMM sockets. P8H61-M PRO technical references identify the board as using DDR3 memory, with PC3-10600 DDR3-1333 and PC3-8500 DDR3-1066 memory standards, two memory channels, and up to 16 GB maximum installed memory in the referenced P8H61-M PRO specification.
These are desktop DIMM sockets, not laptop SO-DIMM sockets. Each memory connector contains many plated contact surfaces, spring contacts, soldered connector legs, and copper alloy structures. If memory modules are present, they are usually sorted separately as RAM scrap. The motherboard itself should retain its DIMM sockets. Missing, cracked, burned, or heavily corroded DIMM slots reduce connector completeness and may lower buying value.
The two-slot memory design also supports D Grade classification. Compared with higher-value boards that may have four, six, eight, or more memory slots and heavier component density, this board is a simplified consumer/OEM desktop board. It has useful recoverable material, but it does not have the density of a laptop motherboard, workstation board, enterprise server board, or Apple logic board.
Expansion Slots
The P8H61-M PRO/CM6630/DP_MB includes a full-length PCI Express x16 graphics slot and additional PCI Express x1 expansion slots. P8H61-M PRO technical references list PCIe 2.0 x16 and PCIe 2.0 x1 slot support, including a standard reference layout with one x16 graphics slot, another x16-length slot operating at x1 mode, and two PCIe x1 slots.
The visible board has a desktop expansion layout suitable for graphics cards, Wi-Fi cards, USB expansion cards, TV tuner cards, sound cards, and other PCI Express devices. These slots contain plated contacts and copper alloy materials, but the motherboard itself does not have a long gold-finger edge connector like an expansion card. Therefore, it should be graded as desktop motherboard scrap, not as gold-finger card scrap.
Expansion slots should remain attached. Harvested slots, cracked slot housings, removed connectors, or heavy mechanical damage reduce the board’s connector value.
Storage, USB, and Internal Connectors
P8H61-M PRO technical references list two SATA 6 Gb/s connectors and four SATA 3 Gb/s connectors. They also list internal USB headers, a TPM connector, COM connector, CPU fan and chassis fan connectors, S/PDIF output header, 24-pin EATX power connector, 4-pin ATX12V power connector, parallel port connector, front-panel audio connector, and system panel connector.
The visible board also has SATA connector groups, front-panel headers, fan headers, and power connectors consistent with a desktop Micro-ATX board. SATA connectors and headers contribute copper, tin, nickel, and soldered contact material. They are not the highest-value components, but they help determine completeness. Removed SATA blocks, missing ATX power connectors, missing front-panel headers, or broken I/O connectors reduce value.
USB 3.0 connectivity is visible in board references for the exact P8H61-M PRO/CM6630/DP_MB family, and the board layout references identify USB 3.0 as part of the mainboard feature set. USB controller sections add IC packages and connector value, but they do not raise the board above D Grade because the overall architecture remains modern consumer desktop construction.
Audio, LAN, BIOS, and Super I/O Sections
P8H61-M PRO technical references identify the onboard audio controller as Realtek ALC887 and the network section as Gigabit Ethernet. The board also includes BIOS flash, Super I/O / hardware-monitoring circuitry, clock oscillators, fan-control support, front-panel control circuits, power regulation, and passive component networks.
The audio and LAN sections are important for model recognition and recycling value. The RJ45 connector contains metal shielding and LAN magnetics. The audio jacks contain plated contacts and soldered connector structures. The audio codec and LAN controller chips contain semiconductor material and bond-wire content. However, these are standard consumer desktop support ICs, not telecom-grade communication processors or enterprise switching ASICs.
PCB Construction and Recycling Value
The board uses a Micro-ATX-style fiberglass PCB with internal copper layers, solder mask, surface-mounted components, through-hole connectors, power planes, ground planes, signal traces, CPU voltage-regulation circuitry, SATA routing, DDR3 routing, and PCI Express routing. P8H61-M PRO references identify the board as Micro ATX.
The board’s recoverable value is mainly based on:
Assumed installed LGA1155 CPU.
LGA1155 socket contacts.
DDR3 DIMM socket contacts.
PCI Express slot contacts.
Intel H61 chipset package.
Realtek audio and LAN controller sections.
BIOS flash and Super I/O circuitry.
SATA, USB, LAN, audio, video, and power connectors.
CPU voltage-regulation MOSFETs, chokes, capacitors, and copper paths.
Multilayer PCB copper.
MLCCs and other passive components.
Solder, tin, nickel, copper, and limited gold-bearing contact surfaces.
This board should be separated from appliance boards and mixed low-grade boards because it is a computer motherboard with CPU-socket and memory-slot value. However, it should not be overclassified as C, B, A, or A+ Grade because it is a later Intel i-series metal-socket desktop motherboard with modest component density and cost-efficient OEM construction.
Ohata D Grade Classification, Identification Guide, and Apple Logic Board Types
Official Ohata D Grade Classification
The official Ohata classification for the ASUS P8H61-M PRO/CM6630/DP_MB motherboard is:
Ohata Board Scrap Classification: D Grade Board Scrap
This classification assumes:
A compatible LGA1155 CPU is installed.
The LGA1155 socket is intact.
The Intel H61 chipset is present.
DDR3 slots remain attached.
PCI Express slots remain attached.
SATA, USB, display, LAN, audio, and power connectors remain attached.
The PCB is complete, clean, dry, and not heavily damaged.
The Ohata Board Grade Class places i-series desktop motherboards with metal CPU socket covers and levers, desktop motherboards with metal sockets, integrated motherboards, and low-grade modern computer boards into D Grade. The detailed D Grade standard explains that D Grade includes later-generation Intel desktop boards, integrated desktop motherboards, AMD AM/FM boards, consumer gaming boards, and cost-efficient computer boards with lower precious-metal concentration than higher grades.
The P8H61-M PRO/CM6630/DP_MB matches those D Grade criteria because it is a later Intel i-series LGA1155 desktop motherboard with a metal socket load mechanism, H61 integrated platform chipset, two DDR3 slots, PCI Express expansion, standard consumer I/O, and relatively modest semiconductor density.
Why the Board Is Not C Grade
C Grade covers standard desktop motherboards, graphics cards, interface cards, connector-end boards, and standard electronic boards with moderate recoverable value. The P8H61-M PRO/CM6630/DP_MB has a complete desktop layout and contains real recovery value, but the Ohata D Grade standard is more specific for this board type.
The board is a later Intel i-series desktop platform with a metal LGA socket and cost-efficient integrated chipset design. Its two-DIMM memory layout, simplified H61 chipset architecture, and moderate controller population give it lower recoverable precious-metal density than stronger C Grade standard desktop boards from earlier or more component-rich designs. Therefore, D Grade is more accurate.
Why the Board Is Not B Grade
B Grade includes medium-value boards such as desktop motherboards with medium-value CPU socket designs, lower-grade telecommunications equipment, peripheral interface boards, embedded controller boards, plastic or metal multi-socket server boards, and entry-level server-type boards. The P8H61-M PRO/CM6630/DP_MB is not a server motherboard, not a telecom board, not a workstation board, and not an embedded industrial controller. It is an ASUS OEM consumer desktop motherboard built for cost-efficient systems.
The assumed installed CPU increases buying value, but it does not change the board architecture. The board remains a D Grade i-series metal-socket desktop motherboard under Ohata’s internal classification.
Why the Board Is Not A Grade or A+ Grade
A Grade includes high-grade computer boards such as non-Apple laptop motherboards, large single-socket server motherboards, clean gold-finger expansion cards, CD/DVD drive controller boards, enterprise backplanes, and selected high-grade computer hardware. The P8H61-M PRO/CM6630/DP_MB is not a laptop board, not a server board, not a clean gold-finger expansion card, and not an enterprise backplane.
A+ Grade includes Apple logic boards, PLC CPU modules, CNC controllers, industrial communication boards, robotics control boards, medical control boards, large multi-socket server motherboards, and other advanced professional electronics. The P8H61-M PRO/CM6630/DP_MB does not have Apple logic-board construction, industrial automation architecture, medical electronics, telecom switching density, or large enterprise server design. It is a consumer/OEM desktop motherboard.
Why the Board Is Not S, SS, or SSS Grade
S Grade is associated with premium legacy computer boards, boards with multiple ceramic CPUs, non-SATA hard drive boards, and earlier enterprise computer hardware with strong precious-metal value. The P8H61-M PRO/CM6630/DP_MB uses a modern organic LGA1155 CPU package and has no ceramic CPU array.
SS Grade is used for enterprise networking, telecom switching, optical communication boards, server backplanes, smartphone logic boards, and high-density communication systems. The board has ordinary desktop LAN, not carrier-grade communication hardware.
SSS Grade is reserved for military, aerospace, satellite, radar, defense, scientific, and mission-critical boards with the highest precious-metal concentration and high-reliability construction. The P8H61-M PRO/CM6630/DP_MB is a mass-produced desktop board and does not match SSS characteristics.
Identification Guide
Step 1 – Confirm Desktop Motherboard Construction
Inspect the board for a desktop Intel LGA socket, full-size DDR3 DIMM sockets, PCI Express expansion slots, SATA connectors, rear desktop I/O, ATX-style power connectors, and Micro-ATX shape. These features confirm that it is a desktop motherboard rather than a laptop motherboard.
Step 2 – Confirm the Model Marking
Look for P8H61-M PRO/CM6630/DP_MB printed on the PCB. The ASUS CM6630 support page references BIOS files for P8H61-M-PRO-ASUS-CM6630-8, supporting the model-family identification.
Step 3 – Confirm LGA1155
The CPU socket should be Intel LGA1155 with a metal load plate and lever. The compatible processor package size is 37.5 mm × 37.5 mm.
Step 4 – Confirm Intel H61
The chipset platform should be Intel H61. The exact P8H61-M PRO/CM6630-8/DP_MB board reference identifies it as an Intel H61-based motherboard, and P8H61-M PRO technical references list Intel H61 Express.
Step 5 – Confirm DDR3 Memory
The board should have two full-size DDR3 DIMM sockets. P8H61-M PRO references list DDR3 memory, two memory channels, DDR3-1333 / DDR3-1066 support, and up to 16 GB maximum installed memory.
Step 6 – Confirm Expansion and I/O
The board should have PCI Express expansion, SATA connectors, USB, display output, LAN, audio, 24-pin ATX power, 4-pin CPU power, fan headers, and front-panel headers. P8H61-M PRO technical references list PCIe slots, SATA 6 Gb/s and 3 Gb/s connectors, rear I/O, and internal headers.
Apple Logic Board Types Comparison
Apple logic boards are not part of this board’s identity. Apple MacBook logic boards are compact, high-density laptop boards with dense BGA packages, fine-pitch connectors, proprietary shapes, and high semiconductor coverage. Ohata’s Apple logic-board guidance treats genuine Apple laptop logic boards as A+ Grade material because of dense integrated-circuit coverage, premium construction, and strong precious-metal recovery value.
The ASUS P8H61-M PRO/CM6630/DP_MB is the opposite type of board: a desktop OEM motherboard with removable LGA1155 CPU, full-size DDR3 DIMM sockets, PCI Express slots, SATA connectors, and ATX-style power input. It should not be mixed with Apple logic board scrap.
Recoverable Materials, Buying Standards, and Handling
Recoverable Materials
The P8H61-M PRO/CM6630/DP_MB contains the material profile expected from Ohata D Grade desktop motherboard scrap. D Grade computer boards contain lower precious-metal concentration than C, B, A, A+, S, SS, or SSS Grade materials, but they remain recyclable because they contain copper, socket contacts, memory-slot contacts, expansion-slot contacts, integrated circuits, solder, nickel-plated connectors, MLCCs, and limited gold-bearing material.
Copper is the largest recoverable metal by weight. It is present in internal PCB layers, power planes, ground planes, CPU voltage-regulation circuitry, inductors, chokes, memory routing, PCI Express routing, SATA routing, USB routing, rear I/O structures, LAN magnetics, and ATX power distribution.
Gold is present in limited but important locations. Gold-bearing areas may include the installed CPU package, LGA1155 socket contacts, DDR3 memory-slot contacts, PCI Express contacts, USB connector contacts, LAN connector contacts, test pads, and gold bond wires inside integrated circuits.
Silver may be present in selected contacts, solder materials, and semiconductor structures.
Palladium may be present in multilayer ceramic capacitors distributed across the board.
Tin and nickel are found in solder alloys, component leads, connector plating, socket underplating, rear I/O shielding, and plated contact surfaces.
Aluminum may be recovered from heatsinks if present, but heatsinks do not define the circuit-board grade. Large aluminum coolers, fans, and brackets can generally be removed separately when the electronic board itself remains complete.
Preferred Buying Condition
A preferred D Grade P8H61-M PRO/CM6630/DP_MB board should have:
Compatible LGA1155 CPU installed when CPU-included material is required.
LGA1155 socket intact.
Intel H61 chipset package present.
DDR3 DIMM sockets present.
PCI Express slots present.
SATA connectors present.
BIOS flash present.
Audio and LAN controller sections intact.
USB controller sections intact.
Rear VGA / DVI / HDMI-class display-output section present according to board revision.
Rear LAN, audio, and USB ports present.
24-pin ATX power connector present.
4-pin CPU power connector present.
Front-panel, fan, USB, COM, S/PDIF, and other headers present.
PCB structurally complete.
Board dry and reasonably clean.
No severe corrosion.
No burn damage.
No water damage.
No battery leakage.
No heavy component harvesting.
No oil, adhesive, paint, chemical residue, excessive thermal paste, or heavy dust contamination.
No mixed low-grade material attached to the motherboard lot.
Functionality is not required for recycling. The board does not need to boot. Its value is based on physical material content, CPU presence, component completeness, connector condition, and contamination level.
Importance of CPU Completeness
The CPU should remain installed whenever the board is purchased as desktop motherboard with CPU material. The compatible CPU package is Intel LGA1155, 37.5 mm × 37.5 mm.
A CPU-installed board is more valuable because the processor contributes recoverable semiconductor material, package substrate, internal metal layers, contact lands, heat-spreader metal, and precious-metal-bearing structures. If the CPU is missing, the board remains D Grade motherboard scrap but should be purchased at a lower value. If the LGA1155 socket is damaged or removed, the downgrade is more severe because the board loses the socket contact field as well.
Keeping the CPU installed improves value within D Grade. It does not raise the board into C Grade, B Grade, A Grade, or A+ Grade because the board remains a modern Intel i-series metal-socket desktop motherboard under Ohata’s internal standard.
Acceptable Removals
The following removals usually do not change the D Grade identity if permanent electronics remain attached:
CPU heatsink.
CPU cooling fan.
Chipset heatsink, if the chipset package remains undamaged.
Loose DDR3 memory modules.
Loose PCI Express graphics card.
Loose PCI Express expansion card.
I/O shield.
Case screws and brackets.
External cables.
Plastic case parts.
Non-electronic accessories.
The detailed D Grade standard allows removal of non-electronic accessories such as heatsinks, fans, brackets, plastic housings, and loose cables, while processors, chipsets, sockets, connectors, and voltage-regulation circuits should remain attached because they contribute directly to recoverable value.
Conditions That Reduce Value
The following conditions reduce buying value:
CPU missing when CPU-installed boards are expected.
LGA1155 socket contacts bent or broken.
CPU socket removed.
Intel H61 chipset removed or damaged.
DDR3 slots removed or cracked.
PCI Express slots harvested.
SATA connectors removed.
BIOS chip removed.
LAN or audio controller sections harvested.
USB controller section harvested.
Rear I/O ports broken or missing.
ATX power connector removed.
PCB cracked, drilled, cut, snapped, or missing sections.
Coin-cell battery leakage.
Heavy oxidation or corrosion.
Burned or carbonized PCB areas.
Water damage or PCB delamination.
Oil, adhesive, paint, chemical residue, excessive thermal paste, or heavy dirt contamination.
Mixed loads containing appliance boards, wire, batteries, plastic, steel, power-supply boards, or unrelated scrap.
The D Grade standard notes that missing processors, removed chipsets, broken PCB sections, heavy corrosion, burn damage, water intrusion, battery leakage, oil contamination, and large cut sections may reduce grade or buying value.
Rejection Conditions
A board may be rejected from sorted D Grade motherboard buying or moved to a lower mixed-PCB category when the expected recoverable structure cannot be inspected. Severe rejection or downgrade conditions include:
Board cut into multiple pieces.
CPU socket removed.
Main chipset package removed.
Heavy IC harvesting.
Severe fire damage.
Severe corrosion across the CPU, memory, chipset, or expansion areas.
PCB swelling or delamination from water damage.
Battery leakage destroying traces.
Heavy chemical contamination.
Mixed trash load where the motherboard cannot be separated.
A clean, complete, CPU-installed ASUS P8H61-M PRO/CM6630/DP_MB is D Grade Board Scrap. A stripped, CPU-missing, broken, corroded, contaminated, or mixed board has lower value.
Handling and Storage
Store the motherboard flat, dry, and separated from heavy scrap. Do not crush it under power supplies, transformers, motors, steel, batteries, or mixed e-waste. Moisture should be avoided because it attacks LGA1155 socket contacts, DDR3 contacts, PCI Express contacts, SATA contacts, USB contacts, LAN contacts, solder joints, chipset pads, and exposed copper.
CPU-installed boards should be separated from CPU-missing boards. D Grade desktop motherboards should be separated from B Grade desktop boards, C Grade standard boards, A Grade laptop boards, A+ Apple logic boards, appliance boards, power-supply boards, batteries, wires, plastics, and mixed low-grade material. Proper sorting protects value and prevents an otherwise acceptable motherboard from being averaged down in a mixed lot.
Comparison, and Official Ohata Classification
Comparison with Laptop Motherboards
Laptop motherboards usually use SO-DIMM slots, flat-flex display connectors, battery charging circuits, compact BGA packages, and irregular notebook shapes. Non-Apple laptop motherboards are generally A Grade under Ohata because of compact multilayer construction and higher component density. The P8H61-M PRO/CM6630/DP_MB is a desktop motherboard with full-size DDR3 DIMM sockets, PCI Express slots, ATX-style power connectors, SATA connectors, and rear desktop I/O, so it should not be sorted as laptop motherboard material.
Comparison with Apple Logic Boards
Apple logic boards are typically A+ Grade because they have dense semiconductor coverage, compact proprietary layouts, BGA processor packages, fine-pitch connectors, and premium multilayer construction. The P8H61-M PRO/CM6630/DP_MB is an ASUS desktop OEM board and must not be mixed with Apple logic-board scrap.
Comparison with B Grade Boards
B Grade boards include medium-grade boards with better component density, stronger connector value, or medium-value CPU socket designs, as well as some lower-grade telecom, embedded, and server-type boards. The P8H61-M PRO/CM6630/DP_MB has a modern LGA1155 i-series metal socket, but Ohata’s Board Grade Class specifically places this socket style and later Intel desktop platform type in D Grade.
Comparison with C Grade Boards
C Grade boards include standard desktop motherboards, graphics cards, trimmed expansion cards, and interface cards with moderate recoverable value. The P8H61-M PRO/CM6630/DP_MB is a complete desktop board, but it is a later consumer i-series motherboard with integrated platform architecture, limited support-chip density, and a metal socket cover/lever. The D Grade standard is the more accurate Ohata classification.
Comparison with Appliance Boards
Appliance boards are designed for motors, relays, compressors, pumps, heaters, sensors, and appliance user interfaces. The P8H61-M PRO/CM6630/DP_MB is a digital computing board with CPU socket, DDR3 memory, PCI Express expansion, Intel H61 chipset, BIOS, SATA, USB, LAN, audio, VGA, DVI, HDMI-class display output, and ATX-style power architecture. It should not be sorted as Appliance Board A or Appliance Board B.

The D Grade classification assumes that the motherboard is complete, clean, dry, structurally intact, and includes the CPU. If the CPU is missing, the Intel H61 chipset is removed, the LGA1155 socket is damaged, major connectors are harvested, the PCB is cracked, or the board is corroded, burned, water damaged, chemically contaminated, or mixed with miscellaneous scrap, the buying value may be reduced or the board may be rejected from the sorted D Grade motherboard category.
The Ohata Board Scrap Classification System is an internal Ohata value-identification and sorting method for electronic scrap purchasing, warehouse grading, and recycling education. It is not an international standard, government regulation, ISO standard, or universally accepted industry classification. Final grade depends on physical inspection, CPU presence, board completeness, contamination level, and actual recoverable material condition.
