Frequently Asked Questions

What is the difference between HMAA4GR7CJR8N-XNB4 and other suffix variants?
All HMAA4GR7CJR8N suffix variants are SK Hynix 32GB DDR4-3200 ECC RDIMM modules with identical specifications. The XNB4 suffix denotes a specific production revision — functionally equivalent to XN, XNT4, XNT8, XNTG, XNB8, and XNBG variants.
Is this module compatible with Intel Xeon Ice Lake processors?
Yes, it is compatible with Intel Xeon Scalable Ice Lake server platforms supporting DDR4-3200 ECC RDIMM. Verify your specific server's QVL before ordering.
Can I mix XNB4 with other HMAA4GR7CJR8N 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.

The SK Hynix HMAA4GR7CJR8N-XNB4 32GB DDR4-3200 ECC Registered DIMM delivers reliable, enterprise-grade server memory performance. Order today for genuine SK Hynix RDIMM quality with proven ECC reliability.
