Frequently Asked Questions

What is the difference between HMA84GR7AFR4N-VKTD and other VK suffix variants?

All HMA84GR7AFR4N VK-suffix variants are SK Hynix 32GB DDR4-2666 ECC RDIMM 2Rx4 AFR die modules with identical specifications. VKTD denotes a specific production revision — functionally equivalent to VK, VKTF, and VKTN.

Is this module compatible with Intel Xeon Skylake processors?

Yes, it is compatible with Intel Xeon Scalable Skylake and Cascade Lake server platforms supporting DDR4-2666 ECC RDIMM. Verify your specific server's QVL before ordering.

Can I mix VKTD with other HMA84GR7AFR4N-VK 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.
