FAQs

Q: Is 1Rx4 different from 1Rx8?
A: Yes. x4 vs x8 refers to DRAM chip data width and can affect platform interleaving and RAS features; check your server’s memory guidelines.

Q: Can I run this with LRDIMM modules?
A: No. RDIMM and LRDIMM should not be mixed.

Q: Will it downclock if my CPU/chipset doesn’t support 3200 MT/s?
A: Yes. It will operate at the highest supported JEDEC speed of the platform.

Q: Is this compatible with desktop motherboards?
A: Most desktop boards do not support RDIMM; use UDIMM for desktops unless the board explicitly supports RDIMM.
