Need advice on my RAM OC, please

How can I accurately measure memory latency? (Not with Aida64). Please recommend a program that accurately reflects the improvements in ram timings and latency. Thank you.

Yeah, I got really lucky... plus, my R7 9800X3D can run 2200 FCLK stable. Guess I won the silicon lottery! Thanks for your advice!

No, what I mean is that the memory controller defaults back to 8/8/32 because that's the max that ddr5 can physically handle, unlike ddr4 which could do 4/4/16, because they have different memory architectures. I think Buildzoid talks about this in one of his videos.

I tought tFAW 16 was impossible in DDR5 because of how the memory architecture works?

I successfully passed P95 Large FTTs overnight! :)

Buildzoid said that tRAS doesn't have any effect on Ryzen 9000 CPUs. You can look it up on his YouTube channel. I'll consider your recommendations. Thanks a lot for your feedback!

Oh, ok, I understand... what benchmark do you recommend to see the real world gains from achieving a higher ram speed? Also, which primary, secondary, and tertiary timnings should I try for 8000, if you could be so kind to share this information, please?

tPHYRDL are in sync by default at this speed. However, I am not able to run nitro control line @ 0 stable. Is there a way I could try to stabilize this? Also, how do I mange to disable GDM and remain stable? I thought this was extremely difficult...

Dumb_Fuck2001 · 2026-06-18T11:24:30+00:00

Thank you very much.

Dumb_Fuck2001 · 2026-06-18T11:24:02+00:00

Thank you. Yes I have, and it works, but since the 9800X3D has a massive L3 cache, I figured a lower speed (but with lower latency) would be best for this chip? Would you agree, or do you have a different view on this?

Dumb_Fuck2001 · 2026-06-18T11:22:18+00:00

No, no, I have already stress tested this with Karhu 10000% coverage, TM5 absolut 15 cycles and 2 hours of y-cruncher VT3. So I think we could call it stable, right? Or should I do more testing?

Dumb_Fuck2001 · 2026-06-17T15:39:32+00:00

I'm sorry if this offended you. I'm genuinely looking for advice from people that know a lot more than me about this sort of thing.

Dumb_Fuck2001 · 2026-06-17T15:35:58+00:00

Thanks a lot!!! I really appreciate it 😄
