Frequently Asked Questions

What is the difference between HMA84GR7DJR4N-WM and the WMT4, WMT8, WMTG, WMTG-AD variants?

All are SK Hynix 32GB DDR4-2933 ECC RDIMM 2Rx4 modules with identical specifications. WM is the base part number while WMT4, WMT8, WMTG, and WMTG-AD are specific production revision or OEM/channel suffixes — they are functionally equivalent.

What is the difference between HMA84GR7DJR4N (DDR4-2933) and HMA84GR7DJR4N-XN (DDR4-3200)?

The WM suffix variants run at DDR4-2933MHz (PC4-23400) while the XN suffix variants run at DDR4-3200MHz (PC4-25600) — they are different speed grades of the same 32GB 2Rx4 RDIMM family.

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.
