AMD Epyc Rome Best Ram ?

[dbiegunski]

ROMED8-2T with 7742

3200 CL22 or 2666 CL19 ? Not sure which one would yield the best performance.

Looking for 8 x 32 for 256

Workload is kubernetes/okd and Windows Server.

Any part number that is worth mentioning ?

Thanks for helping out !

I would start with the tested ram list on the motherboard website: https://www.asrockrack.com/general/productdetail.asp?Model=ROMED8-2T#Memory

Also, a little more info on your specific use case would be helpful for providing recommendations on performance. For example, do you need to maximize memory bandwidth for shared memory parallel calculations? Or do you need to just maximize single core performance?

DDR4 3200 is the best memory for EPYC 7002 and 7003
This is the memory I used: 32GB DDR4 3200MHz PC4-25600 RDIMM 2Rx8 Memory for AMD EPYC 7002 Series processor | eBay

I agree. DDR4 3200 is the best for performance. NEMIX provides a lifetime warranty with low prices (compare with 1 year warranty of Memstore). Make sure you memory test your RAM (especially cheaper brands) within the return window. Consider name brand RAM (Hynix, Samsung, Micron) if you want to minimize the probability of memory errors. I have used a lot of DDR4 3200 NEMIX RAM with EPYC Rome and have had good results.
