I doubt a fan control feature for the chipset fan will happen.

But anyways, use this method for now: https://www.reddit.com/r/Amd/comment...mmend_massive/

I'm waiting for others to start OC so we can discuss controlling VID voltages. Haven't seen anyone talk much about CCX OC here yet.

With this method, I have accomplished the following:

Ryzen Master - All VID voltages controlled to be below 1.325, no thermal warnings happen.
CCX0 4425
CCX1 4425
CCX2 4475
CCX3 4475

der8auer's OC tool - VID voltages spike to 1.38v-1.48v, thermal warnings happen and PC shuts off
CCX0 4425
CCX1 4425
CCX2 4450
CCX3 4450

My scores with der8auer's OC tool is actually higher because Ryzen Master sucks up resources. But Ryzen Master lets me run 4475 because it controls the VID voltages!

I CAN'T GET THE BIOS TO CONTROL THE VID VOLTAGES LIKE RYZEN MASTER DOES!

Hopefully someone here can figure it out. We'll get really nice OCs soon. We need to Overclock and Undervolt the best that we can to maximize boost because if we don't, thermal throttling occurs and these chips heat up quite rapidly due to the way they are designed.

Thank you for sharing the link and info. +Rep

I'm sure as the BIOS and microcode matures you'll be able to overclock better with less volts and lower temps. Maybe the ROG Team can put together an overclock guide to maximize overclocks with minimal temperatures.

I'll locked the computer just then to cook dinner, Chrome was running, when I came back the machine had reboot, checked bluescreens and there was no dump logged other than the first BSOD.
The first BSOD I was just browsing the web (Chrome), and I actually saw the BSOD, the log on that was with the ntoskrnl.exe.

I've run Prime95, Realbench, Cinebench, Memtest all fine, heck I've played hours of GTA V, AC:O, Metro Last Light, so it's not load or memory related.

I have a 3900x (no oc) with a negative -0.100v offset, maybe I need to lower that to -0.05v, it's all I can think of that would be causing a idle crash.

I've notice even with Chrome open my idle voltages when not touching anything drop to about 0.496v occasionally.

System:
3900x
ROG Crosshair VIII Formula
32GB (2x16GB) Gskill Trident 3200Mhz 16-18-18 38 (1.36v)
Samsing Evo 970 Pro 250GB NVMe

I wouldn't use an offset at all. Seems there's not enough volts at idle to maintain your stability.
