That's pretty impressive.

Keep in mind this motherboard doesn't have a heatsink on the SOC VRM and it has quite a bit of vdroop at high loads. So I think reducing the SOC voltage would probably help stability. I don't really like it that high.

Keep an eye on VDDG. There have been reports of CPU boost reduction with high memory frequencies. 1.05 or 1.1 might be needed at 3600+.

Not sure if you have seen this

https://www.techpowerup.com/review/a...nchmark/3.html

But the difference between 3200 14-14-14 and 3600 17-19-19) is very small there is a lot of diminishing returns on IF bandwidth once you get passed 3000mhz and timings become more important. I think most b die users are aiming for CL14 at the highest speed they can manage around 3400mhz.

Ah yes thats what I saw.

So I tried raising vSoc from 1.18125v to 1.18725v to stabilize. It just made me stable for 11 more minutes.

Next I tried raising vDimm from 1.5v to 1.525v. 6hours+ stable with Aida64!!! wooo!

when i get home, I'll lower the vsoc and start tuning timings.

Thats incredible that you have gone from 3133 to 3733 just by changing CPU.

Thanks.
I'm going to repeat that last test later. My pc may have went to sleep mode during that. (which means its at least stable for 30 mins lol)

Ok 3733 was kind of hard! I kept failing a few tests after 10 minutes. Perhaps I didnt know what I was doing.
I decided to see how good I could do 3600mhz. I see the new BIOS and wonder if that may help out.

Here's my latest results with 3600mhz at 1.475v. You were right about vSOC voltage, so I left it at 1.1v.
I learned alot about Ryzen RAM overclocking, I want to see if I can lower my tRCD or tRP soon. Perhaps use this knowledge and chase 3733.

CPU and GPU overclocking do not compare to the hours that RAM overclocking involves.

8hrs of AIDA64 stress test.

You could speed things up if you used TM5 with 1asmus profile. It really hammers the memory and detects errors in under 10 minutes that other tests take hours to detect.

Some of the most important timings for Ryzen performance are loose with your settings. Work on TFAW, Twr, TRFC.

CHECK this video it's very interesting https://m.youtube.com/watch?v=iH3qq_mSxTM

Yep youre absolutely right! I did some more research and tweaked these sub timings.
I didnt take a screenshot of it, but originally, my Mem read speeds were around 51.1GB/s with around 73ns latency.

I tried the safe sub-timings. and got great improvement.
Then I tried the fast sub-timings and got even better improvement.
Went to 52.9GBs and 67.8ns with the safe, and 53.4GBs and 67.6ns with the fast.

Currently stressing my timings along with the fast sub-timings. Wondering where to go next, maybe bring tRP to 14 (along with tRAS and tRC), or try for 3666mhz with the current. maybe both, who knows.

this new bios... did it solve any of the issues of the prior one... I updated anyway, but can't really tell any difference

Intel who?
