ECC UDIMM (unbuffered)

Entry servers built on Intel Xeon E and AMD EPYC 4004 take unbuffered ECC DIMMs, the same physical format as desktop memory but with an extra chip for error correction. They top out at four slots and modest capacities, which is fine for a domain controller, a file server or a small line-of-business application.

The most common mistake is buying desktop non-ECC memory because it looks identical. The server will post with it in some cases and then quietly lose the error correction you paid for.

How we work

A memory engagement starts with evidence, not a parts list. We pull utilization from your monitoring or hypervisor, confirm memory is the real constraint, and only then choose modules that keep every channel populated at full speed.

Firmware comes first. BIOS and BMC updates fix memory training bugs and unlock newer module types, so we baseline them before opening the chassis. Installation is scheduled in a maintenance window and validated with a memory test and an application check before the server goes back into rotation.

Parts are new or tested refurbished with a warranty, matched to the vendor's qualified list or an equivalent specification, and we keep a record of exactly what went where so the next upgrade starts from documentation rather than guesswork.
