Introduction, Construction, Components, and Recycling Value
Introduction
The 132-LF-E657 marking, black EVGA PCB and three PCIe x16-length slots identify the P55 FTW faster than its age or chipset alone. Confirm the LGA1156 socket, four DDR3 slots, onboard POST display and power/reset controls before separating it from similar EVGA P55 models.
This board is a desktop motherboard, not a laptop motherboard. It has a rectangular ATX format, a desktop Intel LGA1156 metal load-plate socket, full-size DDR3 memory slots, desktop expansion slots, 24-pin ATX power input, rear I/O shield area, SATA connectors, and standard case-mounting hole pattern. A laptop motherboard would normally use SO-DIMM memory, flat-flex display cables, battery connectors, proprietary notebook power circuits, and an irregular notebook chassis shape. The EVGA P55 FTW uses none of those laptop-specific layout features.
The board is normally used in custom EVGA-based desktop PCs, gaming systems, overclocking benches, enthusiast repair projects, and personal computer assemblies. It is not limited to one prebuilt computer brand. A PC hobbyist can install it in a standard ATX case with a compatible LGA1156 CPU, DDR3 memory, a discrete graphics card, ATX power supply, SATA drives, and cooling hardware. Review references describe the EVGA P55 FTW as an enthusiast-oriented P55 board with strong CPU power design, onboard clear-CMOS, power and reset buttons, EVBot-related overclocking features, and a black/grey visual style.
For recycling, the board should be treated as a modern consumer desktop motherboard with CPU, not as laptop-board scrap, Apple logic-board scrap, server-board scrap, telecom-board scrap, appliance-board scrap, or graphics-card scrap. Its recoverable value comes from the assumed installed CPU, LGA1156 socket contacts, DDR3 DIMM contacts, PCI Express contacts, PCI contacts, Intel P55 chipset package, dual LAN/audio/controller ICs, BIOS flash, SATA/eSATA connectors, USB/FireWire/S/PDIF connectors, voltage-regulation components, multilayer PCB copper, solder, nickel-plated connector surfaces, MLCCs, and limited gold-bearing contact materials.
Board Identity and Visual Recognition
The correct identification is:
EVGA P55 FTW SLI 132-LF-E657-KR Intel P55 LGA1156 ATX Desktop Motherboard
The board can be identified by the EVGA branding, black enthusiast PCB, LGA1156 socket, 132-LF-E657 board marking, four DDR3 DIMM slots, three long PCI Express x16-length slots, PCI Express x1 slot, two PCI slots, onboard SLI badge, rear dual LAN section, eSATA connectors, FireWire, POST/debug LED, onboard buttons, and dense voltage-regulation area surrounding the CPU socket. EVGA P55 FTW documentation lists the EVGA P55 FTW user guide and describes a 52-page manual, while the product specifications list model 132-LF-E657-KR and identify the board as EVGA P55 FTW SLI.
The board should not be confused with the EVGA P55 SLI, EVGA P55 LE, EVGA P55 FTW 200, or EVGA P55 Classified 200. Those boards share the same general Intel P55 / LGA1156 era, but the P55 FTW 132-LF-E657-KR has a specific enthusiast layout with three PCI Express graphics-length slots, dual LAN, FireWire, eSATA, onboard debug and control features, and the 132-LF-E657 PCB code.
CPU Socket and CPU Package Size
The CPU interface is Intel LGA1156 / Socket H1. Retail specifications list the socket type as LGA 1156 and supported CPU categories as Core i3, Core i5, Core i7, first-generation Intel Core LGA1156, and Pentium.
The correct CPU package size is 37.5 mm × 37.5 mm. Intel’s LGA1156 desktop processor datasheet states that the socket type is LGA1156 and that the package is a 37.5 × 37.5 mm Flip Chip Land Grid Array package. This measurement is essential for scrap identification because LGA1156 CPUs differ from AMD PGA desktop CPUs, Intel LGA775 CPUs, Intel LGA1155 CPUs, and larger LGA1366 packages.
The LGA1156 socket has a metal load plate and retention lever. This socket style is important for the Ohata D Grade classification because the general Board Grade Class specifically lists i-series motherboards with a CPU socket metal cover and lever, as well as desktop motherboards with metal sockets, under D Grade.
For recycling value, the CPU should remain installed whenever the board is purchased as desktop motherboard with CPU material. A CPU-installed EVGA P55 FTW is more valuable than a CPU-missing board because the processor adds semiconductor material, package substrate, contact lands, internal conductive structures, heat-spreader metal, and precious-metal-bearing internal features. If the CPU is absent, the board remains recyclable, but the buying value is lower. If the LGA1156 socket is bent, cracked, burned, corroded, contaminated, or removed, the reduction is more serious because the recoverable socket contact field is also compromised.
Intel P55 Chipset Platform
The chipset is Intel P55 Express. Retail specifications list the chipset as Intel P55. The P55 platform was designed for first-generation LGA1156 desktop processors, with the processor carrying major platform functions such as memory control and PCI Express graphics lanes, while the P55 chipset handles platform I/O such as SATA, USB, PCIe support lanes, and system-management functions.
This board has no onboard video chipset. The product specification lists onboard video chipset as None. Therefore, display output requires a discrete graphics card installed in a PCI Express slot. The lack of VGA, DVI, or HDMI on the rear I/O is normal for this board and should not be treated as damage or missing parts. A graphics card, if present, should be removed and graded separately.
The P55 chipset package is one of the main semiconductor components on the board. It should remain attached and undamaged. If the chipset is removed, cracked, burned, or heavily corroded, the board loses important semiconductor content and should be downgraded in buying value.
Memory Subsystem
The EVGA P55 FTW has four 240-pin DDR3 DIMM slots. Retail specifications list four 240-pin memory slots, DDR3 2600 MHz+ memory support, maximum supported memory of 16 GB, and dual-channel architecture. The EVGA user guide also describes four 240-pin DDR3 memory slots supporting 1 GB, 2 GB, and 4 GB DDR3 technologies.
The memory connectors are important for scrap value. Each slot contains plated spring contacts, soldered connector legs, copper alloy structures, and associated PCB routing. If DDR3 memory modules are installed, they are typically removed and sorted separately as RAM scrap. The motherboard itself should retain the DIMM sockets. Missing, cracked, burned, or heavily corroded memory slots reduce connector completeness and can lower value.
Expansion Slots and Graphics Support
The board was designed for discrete graphics and multi-GPU desktop use. Retail specifications list PCI Express 2.0 x16 support as 1 × x16 or 2 × x8, plus 1 × x4, along with one PCI Express x1 slot and two PCI slots. The board also lists 2-way SLI support. Review coverage describes the graphics layout as optimized for SLI video-card configurations and refers to three PCI Express slots operating at x16, x8, and x4 speeds.
These expansion slots provide recoverable value through plated contact systems, copper alloy pins, soldered connector legs, and PCB copper routing. They also help identify the board as an enthusiast desktop motherboard. However, they do not make the board a graphics card. The motherboard has internal slots; it does not have a long external gold-finger edge connector like a removable PCIe graphics card.
Storage, USB, FireWire, Audio, and LAN
The board provides SATA RAID 0/1/0+1/5/JBOD support and has multiple SATA/eSATA connection points. Retail specifications list two rear eSATA 3 Gb/s ports and SATA RAID support, while the EVGA user guide describes six internal Serial ATA II connectors and notes SATA II data transfer rate support in the motherboard documentation.
The rear-panel and internal I/O are strong visual identifiers. Product specifications list optical S/PDIF output, coaxial S/PDIF output, PS/2, two eSATA 3 Gb/s ports, six rear USB 2.0/1.1 ports, one IEEE 1394a port, six audio ports, six onboard USB 2.0 ports, one onboard IEEE 1394a header, 24-pin power connector, ATX form factor, and 12.0 in × 9.6 in dimensions.
Technical review references identify controller-level details for the EVGA P55 FTW, including Texas Instruments TSB43AB22A FireWire support, dual Marvell 88E8057 Gigabit LAN controllers, and Realtek ALC889 8-channel audio in one review’s analysis. Controller-level details can vary by board revision or reporting source, but the board should be graded by the complete physical component population rather than by one controller name alone.
PCB Construction and Recycling Value
The EVGA P55 FTW is an ATX motherboard measuring 12.0 in × 9.6 in according to retail specifications. It is built on a multilayer fiberglass PCB with copper signal layers, ground planes, power planes, a strong CPU voltage-regulation section, DDR3 routing, PCI Express routing, SATA/eSATA routing, USB routing, LAN magnetics, audio circuitry, BIOS/firmware ICs, and rear I/O soldered connector assemblies.
Its recoverable value comes from a combination of base metals and limited precious-metal-bearing features:
Installed LGA1156 CPU.
LGA1156 socket contacts.
Four DDR3 DIMM slots.
PCI Express and PCI slot contacts.
Intel P55 chipset package.
Audio codec package.
Dual LAN controller packages and RJ45 magnetics.
FireWire controller and connector system.
SATA and eSATA connector contacts.
USB, S/PDIF, audio, PS/2, and rear I/O connectors.
BIOS flash and support ICs.
CPU VRM MOSFETs, chokes, capacitors, and copper routing.
MLCCs containing trace palladium-bearing material.
Multilayer PCB copper.
Tin-based solder and nickel-plated connector metal.
Although the board has enthusiast features, it is still a later Intel i-series desktop motherboard with a metal LGA socket and modern cost-efficient consumer construction. Ohata D Grade covers modern consumer computer boards and lower-value desktop motherboards with lower recoverable precious-metal concentration than higher grades.
Ohata D Grade Classification, Identification Guide, and Apple Logic Board Types
Official Ohata Grade
The EVGA P55 FTW 132-LF-E657-KR is classified as:
Ohata Board Scrap Classification: D Grade Board Scrap
This classification assumes a compatible LGA1156 CPU is installed and the board remains complete, clean, dry, and structurally intact.
The Board Grade Class identifies D Grade as the category for lower-value computer motherboards and specifically includes i-series motherboards where the CPU socket has a metal cover and lever, desktop motherboards with metal sockets, integrated motherboards, and peripheral lower-grade boards. The detailed D Grade standard further explains that D Grade includes later-generation Intel desktop motherboards and modern consumer computer boards made with cost-efficient construction, lower integrated circuit density, lighter gold plating, and lower precious-metal concentration than higher categories.
The EVGA P55 FTW fits this D Grade standard because it is a modern Intel i-series desktop motherboard with a metal LGA1156 socket, Intel P55 consumer chipset, four DDR3 slots, ordinary desktop LAN/audio/controller sections, PCI Express expansion, SATA storage, and ATX consumer construction.
Confirmation Against Detailed D Grade Standard
The detailed D Grade standard emphasizes that modern desktop motherboards often integrate many functions into fewer chipset or CPU packages, reducing support-chip count and precious-metal content. The EVGA P55 FTW shows exactly this transition-era construction. The processor carries major system functions, the P55 chipset consolidates I/O, and the remaining board uses standard consumer support controllers for LAN, audio, FireWire, storage, and BIOS.
The board has a strong VRM area and enthusiast controls, but the grading standard is based on recoverable material value, not gaming reputation, overclocking reputation, or original retail price. Its metal LGA socket places it directly in the D Grade i-series desktop motherboard category.
Why It Is Not C Grade
C Grade covers standard desktop motherboards, trimmed expansion cards, graphics cards, interface boards, and standard-grade electronic boards with moderate recoverable value. The EVGA P55 FTW is certainly more advanced than a basic office board, but the Ohata Board Grade Class gives a more specific rule for i-series metal-socket desktop motherboards: they are D Grade.
The board’s enthusiast branding and extra expansion slots do not overcome the specific D Grade rule. It remains a later Intel desktop board with a metal socket cover/lever, integrated chipset architecture, standard DDR3 memory, and lower precious-metal concentration than older standard desktop boards or higher-grade computer hardware.
Why It Is Not B Grade
B Grade includes medium-value electronic boards such as desktop motherboards with medium-value CPU socket designs, lower-grade telecommunications boards, embedded controller boards, entry-level server boards, and peripheral interface boards with moderate component density. The EVGA P55 FTW has enthusiast features, but it is not a server board, not a telecom board, not an embedded industrial controller, and not an enterprise workstation board. It is a retail consumer Intel P55 motherboard.
Because the Ohata standard explicitly categorizes i-series motherboards with metal socket cover and lever designs as D Grade, the board should not be promoted to B Grade based solely on brand reputation or the presence of overclocking controls.
Why It Is Not A Grade or A+ Grade
A Grade includes non-Apple laptop motherboards, large single-socket server motherboards, clean gold-finger expansion cards, optical-drive controller boards, NEC desktop motherboards from earlier generations, and selected backplane expansion boards. The EVGA P55 FTW 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, industrial control boards, PLC CPU modules, CNC controllers, robotics controllers, medical boards, industrial communication boards, and large multi-socket enterprise server boards. The EVGA P55 FTW is a desktop enthusiast motherboard, not Apple, industrial, medical, or enterprise multi-socket material.
Why It Is Not S, SS, or SSS Grade
S Grade is associated with premium legacy computer boards, multiple ceramic CPU boards, non-SATA hard drive controller boards, and older enterprise hardware with higher precious-metal concentrations. The EVGA P55 FTW uses a modern organic LGA1156 CPU package and contains no ceramic CPU array.
SS Grade is used for enterprise networking, telecom switching, fiber optic communication, server backplanes, cellular infrastructure, and high-density communication boards. The EVGA P55 FTW has dual desktop Gigabit LAN, but not carrier-grade communication architecture.
SSS Grade is reserved for military, aerospace, satellite, radar, defense, and mission-critical boards with exceptional ceramic packages, gold-pin connectors, and ultra-high-reliability construction. The EVGA P55 FTW is a retail consumer desktop motherboard.
Identification Guide
Step 1 – Confirm Desktop ATX Construction
Confirm that the board has full-size DDR3 DIMM slots, desktop PCI Express/PCI slots, 24-pin ATX power, rear I/O, SATA/eSATA connectors, and ATX dimensions. Retail specifications list the form factor as ATX and the dimensions as 12.0 in × 9.6 in.
Step 2 – Confirm EVGA P55 FTW Identity
Look for EVGA branding, the 132-LF-E657 board code, P55 FTW layout, SLI badge, onboard debug LED, onboard power/reset/CMOS controls, dual LAN rear I/O, eSATA, FireWire, and the three PCI Express graphics-length slot arrangement.
Step 3 – Confirm LGA1156 CPU Socket
The board should have an Intel LGA1156 metal socket. The correct CPU package size is 37.5 mm × 37.5 mm.
Step 4 – Confirm Intel P55 Chipset
The board should be an Intel P55 chipset motherboard. Retail specifications list the chipset as Intel P55.
Step 5 – Confirm DDR3 Memory
The board should have four 240-pin DDR3 DIMM slots with dual-channel support. Retail specifications list four 240-pin slots, DDR3 2600 MHz+ support, 16 GB maximum memory, and dual-channel architecture.
Step 6 – Confirm D Grade Indicators
Confirm the metal LGA socket cover and lever, later Intel i-series desktop platform, cost-efficient consumer chipset architecture, standard DDR3 memory, PCI Express desktop expansion, and lack of laptop/Apple/industrial/server characteristics. These match Ohata D Grade indicators.
Apple Logic Board Types Comparison
Apple logic boards are not part of this board’s identity. Apple MacBook logic boards usually have compact proprietary shapes, dense BGA packages, fine-pitch connectors, integrated processors or SoCs, soldered memory, and much higher component density per unit area. Ohata’s Apple logic-board guidance treats genuine Apple laptop logic boards as A+ Grade material because of dense semiconductor coverage, premium multilayer construction, and high-value connector systems.
The EVGA P55 FTW is the opposite type of board: a full-size ATX retail desktop motherboard with removable CPU, full-size DIMM slots, desktop expansion slots, and ordinary consumer desktop I/O. It should not be mixed with Apple logic board scrap.
Recoverable Materials, Buying Standards, and Handling
Recoverable Materials
The EVGA P55 FTW contains the typical recoverable material profile of a D Grade desktop motherboard. D Grade boards contain lower precious-metal concentration than C, B, A, A+, S, SS, or SSS Grade materials, but they remain important for copper recovery and limited precious-metal recovery because of their massive supply volume and consistent construction.
Copper is the largest recoverable metal by weight. It is present in internal PCB layers, voltage-regulation traces, power planes, ground planes, PCI Express routing, DDR3 routing, SATA routing, USB routing, LAN magnetics, inductors, chokes, and connector pins.
Gold is present in limited but important locations. Gold-bearing areas may include the installed CPU package, LGA1156 socket contacts, DDR3 DIMM slot contacts, PCI Express slot contacts, PCI slot contacts, USB 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 present in solder alloys, connector plating, socket underplating, component leads, and rear I/O shielding.
Aluminum may be present if CPU, chipset, or VRM heatsinks remain attached. Aluminum is recyclable, but heatsinks and fans do not define the PCB grade.
Preferred Buying Condition
A preferred D Grade EVGA P55 FTW board should have:
Compatible LGA1156 CPU installed when CPU-included material is required.
LGA1156 socket intact.
Intel P55 chipset present and undamaged.
Four DDR3 DIMM slots present.
PCI Express and PCI slots present.
SATA/eSATA connectors present.
Audio codec section present.
Dual LAN controller section present.
FireWire controller and header/port present.
BIOS flash and support ICs present.
Rear USB, LAN, audio, S/PDIF, PS/2, eSATA, and FireWire ports present.
Onboard debug LED and onboard buttons present where not physically damaged.
24-pin ATX power and CPU power connectors present.
PCB complete, dry, and reasonably clean.
No severe corrosion, burn damage, water damage, battery leakage, or chemical contamination.
No heavy component harvesting.
No mixed non-board waste attached.
Functionality is not required. The board does not need to boot. Scrap value is based on CPU presence, board completeness, recoverable material, connector content, socket condition, and contamination level.
CPU Completeness and Value
The CPU is the most important removable value item on this motherboard. The correct CPU package is Intel LGA1156, 37.5 mm × 37.5 mm. A CPU-installed board is more valuable because the CPU contributes semiconductor die material, package substrate, contact lands, heat-spreader metal, internal conductive structures, and precious-metal-bearing internal material.
If the CPU is missing, the board remains D Grade motherboard scrap, but the value is lower. If the socket is also damaged or removed, the board may be downgraded more severely. Retaining the CPU improves buying value within D Grade; it does not raise the board into C Grade or B Grade because the overall Ohata rule still identifies i-series metal-socket desktop motherboards as D Grade.
Acceptable Removals
The following removals usually do not change the D Grade identity if permanent electronics remain attached:
CPU heatsink.
CPU fan.
Chipset heatsink, if the chipset remains undamaged.
VRM heatsink, if MOSFETs, chokes, and controller ICs remain attached.
Loose DDR3 memory modules.
Loose graphics cards.
Loose PCI or PCI Express cards.
I/O shield.
Case screws and brackets.
External cables.
Plastic case parts.
Non-electronic accessories.
The D Grade standard allows removal of non-electronic accessories such as heatsinks, cooling fans, brackets, plastic housings, and loose cables, while permanent components such as processors, chipsets, sockets, connectors, and voltage-regulation circuits should remain attached.
Conditions That Reduce Value
The following conditions reduce buying value:
CPU missing when CPU-installed boards are expected.
LGA1156 socket bent, cracked, burned, corroded, or removed.
Intel P55 chipset removed or damaged.
DDR3 slots removed or broken.
PCI Express or PCI slots harvested or cracked.
SATA or eSATA connectors removed.
Audio, LAN, FireWire, or BIOS controller ICs removed.
Rear I/O ports broken or missing.
24-pin 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 delamination.
Oil, adhesive, paint, chemical residue, or excessive thermal paste.
Mixed loads containing appliance boards, wire, batteries, plastic, steel, power-supply boards, or unrelated low-grade scrap.
The detailed D Grade standard states that missing processors, removed chipsets, broken PCB sections, heavy corrosion, burn damage, water intrusion, battery leakage, oil contamination, and large cut sections may reduce classification or buying value.
Rejection Conditions
A board may be rejected from sorted D Grade motherboard buying or moved to a lower mixed-PCB category if the expected recoverable structure cannot be inspected. Serious rejection or downgrade conditions include:
Board cut into multiple pieces.
CPU socket removed.
P55 chipset removed.
Heavy IC harvesting.
Severe fire damage.
Severe corrosion across CPU, memory, or chipset 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 EVGA P55 FTW 132-LF-E657-KR 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 LGA1156 socket contacts, DDR3 contacts, PCI Express contacts, PCI 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 boards 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 are typically smaller and denser, using SO-DIMM memory, flat-flex display connectors, battery/power circuitry, fine-pitch board connectors, and proprietary notebook shapes. Non-Apple laptop motherboards are generally A Grade under Ohata because of their compact multilayer construction and higher component density. The EVGA P55 FTW is a desktop ATX motherboard with full-size DIMMs, PCI Express slots, PCI slots, and ATX power.
Comparison with Apple Logic Boards
Apple logic boards are usually A+ Grade because they contain very dense BGA packages, compact proprietary layouts, fine-pitch connectors, and higher component concentration per unit weight. The EVGA P55 FTW is a retail desktop board and should not be mixed with Apple logic-board material.
Comparison with B Grade Boards
B Grade includes medium-grade electronic boards, including desktop motherboards with medium-value CPU socket designs, lower-grade telecom boards, peripheral interface boards, and entry-level server-type boards. The EVGA P55 FTW has enthusiast features, but the Ohata Board Grade Class specifically places i-series desktop motherboards with metal CPU socket covers and levers in D Grade.
Comparison with Appliance Boards
Appliance boards control motors, pumps, relays, compressors, heating elements, sensors, and appliance user interfaces. The EVGA P55 FTW is a digital computing board with CPU socket, DDR3 memory, PCI Express graphics expansion, Intel P55 chipset, BIOS, SATA, USB, LAN, audio, FireWire, and ATX 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 P55 chipset is removed, the LGA1156 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.
