Frequently Asked Questions

What is the difference between HMA84GR7DJR4N-WMT4 and other WM suffix variants?

All HMA84GR7DJR4N WM-suffix variants are SK Hynix 32GB DDR4-2933 ECC RDIMM 2Rx4 modules with identical specifications. WMT4 denotes a specific production revision — functionally equivalent to WM, WMT8, WMTG, and WMTG-AD.

Is this module compatible with Intel Xeon Cascade Lake processors?

Yes, it is compatible with Intel Xeon Scalable Cascade Lake server platforms supporting DDR4-2933 ECC RDIMM. Verify your specific server”s QVL before ordering.

Can I mix WMT4 with other HMA84GR7DJR4N-WM revision variants?

Mixing production revisions of the same module family is generally supported, but consult your server documentation and QVL for mixed-revision DIMM configuration guidance.
