FAQs

Q: Will my server run this at 6400 MT/s?
A: Only if your CPU and motherboard support 6400 MT/s with the planned DIMM population. Otherwise it will operate at the platform’s maximum supported speed.

Q: Is mixing with lower-speed DDR5 allowed?
A: Yes, but all modules will downclock to the lowest common speed and timing.

Q: What rank is this DIMM?
A: It is a dual-rank (2Rx4) ECC Registered RDIMM.

Q: Any special installation guidance?
A: Follow your server’s DIMM placement guidelines for optimal speed and interleaving.
