What each brand pays
Brand changes what used memory are 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.

What this module is
A 128GB DDR5 registered ECC RDIMM at 4800 MT/s (PC5-38400), a workhorse capacity for Sapphire Rapids and first-gen EPYC Genoa-era servers. Registered DDR4 held its bid through the 2025-26 memory crunch; with fabs pivoting to DDR5, clean modules like this keep clearing within days. The most liquid stock is Samsung, SK Hynix, and Micron; we grade every stick on the bench and pay from the measured spec. Common part numbers include M321RAGA0B20-CWK and HMCT04MEERA.
Part numbers we buy

Questions
How much is a 128GB DDR5-4800 ECC RDIMM worth in 2026?
Our current indicative payout is $1,253-$1,567 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 shows what we actually paid over the trailing 30 days.
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 SSD and laptop we buy is erased to NIST 800-88 with a free emailed certificate.
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.
