What each brand pays
Brand changes what used memory is worth — Samsung sets the benchmark, then the other tier-one makers, and value brands pay a little less. We still buy every brand on this list.
| Brand | Indicative payout |
|---|---|
| Samsungbest price | $45–$50 |
| SK Hynix Tier-1 OEM DRAM; near-Samsung liquidity in the server channel. | $43–$48 |
| Micron Tier-1 OEM DRAM; strong data-center demand. | $42–$47 |
| Crucial Micron's retail arm — genuine Micron silicon, thinner enterprise resale. | $40–$44 |
| Kingston Reliable, high-volume module maker; softer resale premium than the OEM three. | $38–$42 |
| Corsair Enthusiast/desktop brand; limited server-channel demand. | $36–$40 |
| G.Skill Enthusiast/desktop brand; limited server-channel demand. | $36–$40 |
| ADATA Value module maker; lower used-market liquidity. | $34–$38 |
| Third-party Nemix, A-Tech, Timetec and similar third-party assemblers — we still buy, at a lower payout. | $30–$33 |
| Unknown Unbranded or unidentifiable modules; priced conservatively, still purchased. | $27–$30 |
Ranges are non-binding and scaled from the Samsung benchmark for this exact spec — your firm quote comes by email within 4 business hours.

What this module is
A 16GB DDR4 registered ECC RDIMM at 2666 MT/s (PC4-21300), a workhorse capacity for Skylake and Cascade Lake-era servers. The 2025-26 DRAM shortage pushed modules like this sharply higher as DDR4 production winds down and cloud refurbishers compete with homelab builders for a shrinking pool. Dual-rank modules from Samsung, SK Hynix, and Micron are the most liquid and move fastest through our wholesale channels. Common part numbers include M393A2K40CB2-CTD and HMA82GR7AFR8N-VK.

Questions
How much is a 16GB DDR4-2666 ECC RDIMM worth in 2026?
Our current indicative payout is $45-$50 per unit in used working condition, with the firm number emailed within 4 business hours of your quote request. The range moves with the market — the Payout Index tracks the price we pay week over week.
Will a module pulled from a working server count as "used, working"?
Yes — pulled-from-working with an intact label and clean pins is exactly our base grade, quoted at the full range shown. Our bench verifies with an SPD read and a MemTest pass, and the measured spec always wins over the sticker.
Do I need to wipe RAM before selling it?
No — DRAM is volatile and loses its contents at power-off, so there is nothing to wipe by the time it reaches us. Storage is different: every drive we buy is erased to NIST 800-88, and the erasure report is yours on request.
What if I have more than eight sticks?
Quantity helps you: 8+ identical modules earn +3%, 32+ earn +6%, and pallet-scale lots go through our business desk with a manifest quote and New England pickup available.
How fast do I actually get paid?
Zelle or PayPal within 48 hours of test completion; typical mail-to-money is 5-7 days end to end. Your quote locks before you ship, and if the market drops after we quote, we pay the quote anyway.
