Product overview
The SK hynix 96GB DDR5-6400 PC5-51200 ECC registered RDIMM 2Rx4 288-Pin Server Memory Module is supplied under part number HMCGM4MHBRB. Memory is the part most often ordered wrong, because rank, voltage and population rules differ per platform and per slot. This module is DDR5-6400. Give us the server model and the DIMMs already fitted and we will confirm the configuration is supported.
Send a photo or a dump of the current DIMM layout and we will map the population for you before you order.

What you get ordering this from us
Ordered by part number
The order is placed against HMCGM4MHBRB, not against a description of it, so there is no room for a substitution you did not agree to.
No substitutions without asking
If we cannot supply the exact code we tell you what we can supply and why, rather than shipping an equivalent and letting you find out.
Population mapped for you
Send the current DIMM layout and we return the slot map with the quote, so the modules go in the right order.
Questions buyers ask about this part
- Is HMCGM4MHBRB genuine and is the warranty intact?
- Yes. It ships new in SK hynix packaging, which is what keeps the warranty and the firmware entitlement valid. Anything we cannot supply that way we tell you about before you order.
- Will HMCGM4MHBRB work in my server?
- Send the server model and a list of the DIMMs already fitted. Rank, voltage and population order all have to agree, and a module that is electrically compatible can still be unsupported in a given slot. We map the population before you order.
- Do you accept purchase orders and quote at volume?
- Yes. We quote against a purchase order and hold the price for the quote period, with tiered rates at quantity. Net terms are available once the account is approved.

Specifying a system, not just the part?
Host memory on an AI node is normally sized against accelerator memory, so the model and its working set both fit.
