Technical Specifications

FAQs

Q: Is this compatible with Gen10 servers?
A: No. Gen10 platforms use DDR4. This DDR5 RDIMM is intended for ProLiant Gen11 systems that support DDR5.

Q: Can I mix RDIMM and LRDIMM in the same server?
A: No. Mixing RDIMM and LRDIMM is not supported.

Q: What happens if I mix different memory speeds?
A: The memory will operate at the lowest common supported speed and timings per CPU and population rules.

Q: Does rank or chip organization matter when combining modules?
A: Yes. Follow the server’s population guidelines; mixing 1Rx8 and 2Rx8/2Rx4 is usually supported but may affect maximum speed.
