FAQs

Q: What is the organization of this DIMM?
A: It is a 4Rx4 DDR5 RDIMM using 16Gbit DRAM components.

Q: Can I use this with 2Rx4 DIMMs in the same server?
A: Some servers restrict mixing different ranks or organizations within a channel. Check your server’s memory population guide.

Q: Will this work in any DDR5 system?
A: Only in systems that support DDR5 ECC Registered DIMMs (server/workstation platforms).

Q: Does it support error correction?
A: Yes, it includes ECC for detection and correction of memory errors.

Q: What happens if the server supports higher speeds than 4800 MT/s?
A: The memory will operate at the module’s rated speed or the platform’s supported speed, whichever is lower.
