RAM compatibility for HPE servers

Aco Strkalj asked:

I ordered a HPE ProLiant DL325 G10 server. It comes with a AMD EPYC 7401P and 32GB (2x16GB) DDR4 2666MT/s 2Rx8 RDIMMs. I’d like to add more RAM to it. I’m wondering if I can buy non-HPE branded RAM and save a bunch of money and have no compatibility issues. I looked up the module part numbers for the 16GB & 32GB sticks HPE sells. I found them a lot cheaper without the HPE sticker. Will these work perfectly without any issues? And is there really anything different in the hardware in HPE RAM?

My answer:

Yes, you can buy cheaper RAM from third parties and have it work in the system, provided you buy the correct RAM (ECC RDIMM/LRDIMM DDR4-2666 1.2V CL19).

Keep in mind that third party hardware isn’t covered by the HPE warranty, and it even explicitly states that your warranty is void if a hardware failure is caused by third party hardware. If your third party RAM blows up the motherboard, no HPE warranty service for you. Of course that’s extremely unlikely, but it is a risk you have to account for.
