RAM-C (Mixed and Damaged RAM) Grade buying scrap price

Introduction, Construction, Components, and Recycling Value

All qualifying modules are purchased at the applicable RAM C Grade price, regardless of their original retail price, memory capacity, operating frequency, or manufacturer. A damaged high-capacity module does not automatically retain a higher recycling grade. Ohata grading is primarily based on recoverable construction, connector condition, component content, cleanliness, and the labor required to prepare the material for processing.

A typical RAM module consists of a fiberglass-reinforced printed circuit board, copper circuitry, memory IC chips, small passive components, identification labels, and a plated edge connector. Some modules also include heat spreaders, thermal pads, clips, shields, or other attachments. Although RAM contains recoverable metals, its recycling value depends heavily on how easily the material can be identified, sorted, dismantled, and processed.

RAM C Grade usually has lower value than clean and correctly separated RAM because mixed types and poor physical condition increase handling costs. Workers may need to separate different module families, remove foreign materials, clean dirty boards, inspect broken sections, and determine whether the remaining material is suitable for recovery. Therefore, its price reflects both the recoverable metal content and the additional preparation required.

Ohata RAM C Grade Classification, Identification Guide

Under the Ohata Board Scrap Classification System, RAM C Grade is defined as mixed and damaged RAM. The principal identifying conditions are:

• Mixed RAM types, generations, grades, or physical conditions in one lot.

• Broken, cracked, chipped, bent, or otherwise damaged memory modules.

• Dirty RAM containing dust, mud, grease, residue, or other contamination.

• RAM supplied with attachments that must be removed before processing.

• Unsorted memory that requires classification before recycling.

The grading process begins by confirming that the item is an actual RAM module. It should retain the recognizable construction of computer memory, including a narrow memory PCB, edge-connector area, and memory-related IC layout. Items that are not RAM should not be included in this grade.

Next, the inspector evaluates the overall lot rather than choosing a grade solely from the best module present. For example, a container may contain clean gold-finger desktop RAM, shielded modules, trimmed modules, damaged SO-DIMMs, and boards with attachments. If these materials are mixed together and require extensive sorting, the shipment may be handled as RAM C Grade until properly separated.

Physical damage must also be considered. Modules with cracked PCBs, broken corners, bent boards, missing sections, damaged connector edges, or attached foreign parts normally fall into C Grade when they remain recognizable and recyclable as RAM. However, completely destroyed, heavily fragmented, hazardous, or unidentifiable electronic material may be rejected or classified outside the RAM category.

The following inspection sequence is recommended:

1. Confirm that every item is a genuine memory module.

2. Check whether the lot contains mixed RAM generations or construction types.

3. Inspect the PCB, IC chips, and connector area for damage.

4. Look for dirt, oil, moisture, corrosion, adhesive, or hazardous contamination.

5. Identify heat spreaders, clips, cables, sockets, or other attachments.

6. Determine how much sorting, cleaning, or dismantling is required.

7. Separate higher or lower grades whenever practical.

8. Assign RAM C Grade when mixed condition, damage, contamination, or preparation labor is the defining characteristic.

Capacity markings such as 2 GB, 8 GB, or 32 GB do not determine the scrap grade. Likewise, a famous manufacturer’s label does not override the physical buying condition.

Recoverable Materials, Buying Standards, and Handling

RAM C Grade can still contain several recoverable materials:

• Copper: Found in internal PCB tracks, electrical planes, and plated-through holes.

• Gold: May be present on edge contacts, connector plating, and in microscopic IC bonding structures.

• Silver: Commonly associated with solder alloys and certain electronic contacts.

• Palladium: May occur in small quantities within multilayer ceramic capacitors.

• Nickel: Frequently used as a barrier layer beneath connector plating.

• Aluminum: Often found in heat spreaders and attached cooling covers.

• Tin and other alloys: Present in solder joints and some silver-colored connector surfaces.

Ohata buys RAM C Grade according to the condition of the delivered material, not according to its former functional performance. Testing whether each module still works is normally less important than inspecting its construction and recycling condition.

Acceptable C Grade loads may include mixed DIMMs and SO-DIMMs, damaged but identifiable memory boards, dirty modules, RAM with heat spreaders or attachments, and batches that need substantial sorting. Sellers should keep the material dry and free from hazardous substances. Batteries, loose steel parts, cables, packaging, plastic trays, and unrelated electronic components should be removed whenever possible.

RAM should not be deliberately crushed or shredded before inspection. Excessive breakage makes identification difficult and may reduce the recoverable yield. Wet, burned, chemically contaminated, or hazardous material should be disclosed before delivery and may be downgraded or refused.

For better value, sellers should separate clean gold-finger server RAM, clean desktop or laptop RAM, shielded or trimmed RAM, damaged RAM, and blank memory boards into different containers. Proper separation reduces inspection time and helps prevent higher-value modules from being purchased at the lower mixed-lot price.

Comparison and Official Ohata Classification

The easiest way to distinguish RAM C Grade from the other Ohata grades is to compare construction, condition, and processing requirements.

Comparison and Ohata Classification

Ohata distinguishes RAM grades by physical construction, connector type, installed components, completeness, condition, and required processing.

RAM-S Grade primarily includes qualifying server or enterprise memory with gold-plated edge contacts, ECC or registered characteristics, and high component density.

RAM-A Grade generally includes standard desktop DIMMs and laptop SO-DIMMs with intact gold-plated edge contacts.

RAM-B Grade includes modules with aluminum heat spreaders or shields, silver- or tin-colored edge contacts, or previously trimmed contact sections. Customers do not need to remove heat spreaders or shields before delivery.

RAM-C Grade includes recognizable RAM that is damaged, significantly dirty, contaminated, supplied with non-standard attachments, or mixed with different grades and physical conditions requiring additional sorting. Different brands, models, capacities, or DDR generations do not automatically make a load RAM-C.

RAM-D Grade includes blank or nearly blank memory boards with no integrated circuits or very few components, including certain test and dummy modules.

Not classified as RAM applies when the material cannot be identified as a genuine memory module or is unsuitable for classification within the RAM categories.

Recognizable modules that meet the mixed-or-damaged requirements are evaluated as RAM-C Grade. Brand, capacity, DDR generation, and original purchase price do not determine the grade by themselves. Separating higher-grade modules from damaged, contaminated, and lower-grade material supports accurate inspection and classification.
