Sell Used RAM: DDR4, DDR5 and Server Memory.
Bulk buyback of memory modules pulled from servers, desktops and laptops. Server memory is often the part companies overlook in retired racks.
PrivAce Technologies buys used memory modules: server RDIMM and LRDIMM, desktop UDIMM and laptop SO-DIMM, in DDR3, DDR4 and DDR5, from Samsung, SK hynix, Micron, Kingston and other brands. Price depends on generation, type, capacity and speed.
No minimum quantity. Payment before pickup. Modules are tested before resale.
Memory we buy, by type.
| Type | Where it comes from | Generations |
|---|---|---|
| RDIMM (registered, ECC) | Rack and tower servers | DDR3, DDR4, DDR5 |
| LRDIMM (load reduced) | High-memory servers | DDR4 |
| UDIMM (unbuffered) | Desktops and workstations | DDR3, DDR4, DDR5 |
| SO-DIMM | Laptops and mini PCs | DDR3, DDR4, DDR5 |
| Soldered LPDDR | Thin laptops, MacBooks | LPDDR4X, LPDDR5 |
How to read a memory module label.
Most modules carry a JEDEC label such as 32GB 2Rx4 PC4-2933Y-RB2. PC3 means DDR3, PC4 means DDR4 and PC5 means DDR5. On DDR4 and DDR5 labels the number after it is the speed, here 2933 megatransfers per second. On DDR3 labels it is bandwidth instead, so PC3-12800 is DDR3-1600.
The letter after the dash gives the module type: R for registered (server RDIMM), L for load reduced (LRDIMM), U for unbuffered (desktop) and S for SO-DIMM (laptop). 2Rx4 means two ranks built from x4 chips, which is typical of server memory.
The part number identifies the exact module. Samsung part numbers start with M3 or M4, SK hynix with HMA or HMCG, and Micron with MTA on DDR4 and MTC on DDR5. Samsung, SK hynix and Micron make most of the world's DRAM chips, so these three names appear on most server and OEM modules.
DDR3 arrived around 2007, DDR4 around 2014 and DDR5 platforms from late 2021. DDR3, DDR4 and DDR5 are all collected.
What we check at inspection.
Equipment is inspected before the quotation. These are the things that matter most.
| What we check | Ideal | Needs attention |
|---|---|---|
| Generation | DDR5, DDR4 | DDR3 and older |
| Type | Server RDIMM and LRDIMM | Low-capacity desktop modules |
| Capacity | 32 GB, 64 GB and larger | 4 GB and smaller |
| Speed | DDR4 2933 and 3200, DDR5 | DDR4 2133 |
| Quantity | Matched sets of one part number | Mixed loose modules |
| Condition | Clean contacts, labels intact | Damaged or unlabelled |
Prepare memory for a quote.
- Group modules by part number if you can. Matched sets are quicker to test.
- Keep modules in anti-static bags or trays.
- Photograph a label from each type so we can quote before pickup.
- If the memory is still in servers, we can pull it during decommissioning.
Other equipment we buy.
Questions, answered.
No. RAM is volatile and loses its contents when power is removed, so it does not need data destruction. The drives in the same machine do.
All of it: server DDR5 and DDR4 RDIMM and LRDIMM, laptop SO-DIMMs and desktop DIMMs, down to DDR3.
Yes, and Kingston, Crucial, Corsair and other brands. Server and OEM modules are most often Samsung, SK hynix or Micron.
No. A handful of modules is accepted, and large lots from data centre refreshes are welcome.
