OK..so I´ve been following the discussion both in this forum and on Overclock.net, about the whole bios snafu..and as many others trying to get a stable system. I made this post in the Overclock.net forum so I´ll just quote my self from that post.
I´m using Arch Linux so I don´t have the same tools and options as you guys have.
So AFAIK there is no way for me to check logs for WHEA and error code 41 (if memory serves correctly) since the logging and error reporting works differently.
Relevant hardware as follow:
Crosshair 8 Formula
Ryzen 7 3700X
32GB (4x8) Corsair Dominator Platinum 3200mhz (CMT32GX4M4Z3200C16, wich is QVL certified by asus)
The problem I was having is connected to running all 4 dims populated and also using the PBO Fmax. As soon as I turn on the PBO Fmax, my system hangs/freezes randomly while idling (mostly). The only way to get stability was to use 2 ramsticks and refrain from using PBO Fmax, wich I simply refused to settle with.
Some times it could run prime 5 hours straight (small, large or blended FFTS, doesn´t matter) without a problem, rendering movies, looping game benchmarks and all other loads I throw at it without any problems. And then 15 mins after I stop the torture, while the rigg is idling it just freezes up completely. And other times the rigg was on for 36hours days without any problems and all of a sudden while streaming a movie it freezes/hangs again. A couple of times it even froze during booting the os.
YEAH YEAH I KNOW !! 🙂 ....I could just have turn off the Fmax and be done with it. But my cpu and system is responding really well to it performance wise, and I actually got really nice clocks out of my cpu. And also it bugged me that others could run just fine with Fmax and my system wouldn´t.
So I just had to figure out what it was and why.
So I have tried all bios from 0039 up until the latest 2702.
I have played around and tested almost every days since the 0039 bios was released.
Trying out suggestions in this thread, high and low. Turning on and off "Global c-states", "DF c-states", playing around with diffirent "scalar" and and trying 0-200mhz, different LLC, different voltage settings (vcore, vsoc, vddg e.t.c) and trying different current limits e.t.c. I´ve also been trying out different kind of ram settings and even remove 2 of the sticks to eliminate the possibility of 4-stick ram incompatibility. I just couldn´t get it stable !
And then, a couple of days ago the 3003 bios was released, and of course I had to try that one to, not actually thinking it would make any difference.
But lo and behold, so far it´s still holding it´s own, no hangs, freezes or other hick-ups.
I´ve spent the last couple of days lowering and fine tuning the relevant voltages and settings
So far it´s been stable..holding my fingers crossed.
So yeah bios 3003 did the trick for me at least !
Unless I need to, due to cpu-upgrade, I won´t be touching the bios any time soon.
