Frequently Asked Questions

What is the difference between HMA82GU7DJR8N-XN (ECC UDIMM) and HMA82GR7DJR8N (RDIMM)?

HMA82GU7DJR8N-XN is an ECC Unbuffered DIMM (UDIMM) while HMA82GR7DJR8N is a Registered DIMM (RDIMM). The U in GU7 denotes Unbuffered while R in GR7 denotes Registered — they are not interchangeable.

Does ECC UDIMM require special motherboard support?

Yes, ECC UDIMM requires explicit motherboard/platform support for ECC. Not all consumer platforms support ECC — verify your platform”s ECC UDIMM compatibility before ordering.

Is HMA82GU7DJR8N-XN compatible with AMD Ryzen Pro platforms?

Yes, AMD Ryzen Pro platforms with ECC UDIMM support are compatible. Verify your specific motherboard”s ECC UDIMM support before ordering.
