Frequently Asked Questions

How do I read a Hynix HMA part number?

HMA part numbers encode capacity and speed in the suffix. Example: HMA42GR7AFR4N-TF = 16GB DDR4-2133 PC4-17000 ECC RDIMM. The first 3 chars after HMA encode capacity tier, ranks and form factor; the last 2-3 chars after the dash encode speed and voltage.

Are SK Hynix modules cross-validated with Samsung on Dell servers?

Yes — Dell PowerEdge QVL lists both Hynix and Samsung as validated for the same DIMM slots. You can mix manufacturers across sockets but should not mix within a single CPU's memory channels for optimal interleaving.

Where do refurbished Hynix DIMMs come from?

From decommissioned enterprise datacenter assets, post-lease enterprise fleet refresh, and certified vendor takebacks. Every refurb DIMM passes a 12-hour memtest86+ burn-in before re-warranty under our 12-month advance-replacement program.
