Including using APBDIS? That will let you set a fixed SOC P-state of 0. I'm not sure if that's what the other setting does or not.

I used to get idle BSODs with memory overclock on AFRs to 3600 MHz, and couldn't find the right setting to loosen to get it 100% stable.

Using completely the same settings, it seems I'm no longer getting BSODs on idle.
Hynix AFR on 3600? That is not everyday, as they usually clock like ****. Could explain some of the BSODs, just amazing they even boot

BCLK - From what I've read, certain NVME drives don't play nice with it, but, I've not had that issue with these 3 M.2s I've been using whatsoever. SN 550, XLR8 3030, or the Intel 660, all play nice at raised bclk, and one of them is in a PCIE slot adapter running through the chipset in 2.0 mode for mass storage and keep the gpu at x16.

From your SIG specs, i would point at the 970 drive, they're amazing drives but it's the only thing that I see that might be the issue...

I do have wifi disabled... if that matters I don't know.

Optane, I know doesn't like boosted bus speeds.
That's what weird. I used to use high BCLK when benchmarking my 2700X. The only thing different now is the CPU.

Edit:
I mis-remembered and I didn't use BCLK as high as 103+ and the behavior is POST with no Windows. Just the ASUS splash screen so I'm guessing it's the NVME drive.

I can't post at 1900 with LN2 disabled I can with it Enabled. I'm not stable at 1900 either way, but am stable at 1895 with it enabled, but unstable at 1895 with it disabled. No placebo, definite change in behaviour.

I am NOT suggesting to flip the LN2 switch on the board!! (For anyone else reading in the future).

Board switch = very not ok on ambient lol.

Spoiler!
Nice. Going to give this a run with my 3900x on my Test Bench. It has no problem booting at 1900 FClock, but every now and again there are weird stability issues, so I dropped it down to 1800 and those disappeared. The Chip is currently in my Server, but am doing some serious upgrading this next weekend, so I will pop the 2700x back into the server for now, pop the 3900x into my new test bench, and then get to testing.

Unfortunately regarding BCLK that is something you have to be careful with. For anyone running Just a graphics card, and One Sata Drive it shouldn't be much of an issue, but for those of us who have workstations set up, that use Raid Arrays with Raid Cards and 10Gb Network Cards, and even NVMe Drives, you can cause yourself real issues going above 101 BCLK. And the hard part is that every device is different, so some Devices might not have problems until they reach 103BCLK, others Might have an issue once you hit 101.2 BCLK, so I would just advise if you have a NVMe Drive to just back it up before Raising BCLK because you don't know at which point it will start complaining, and unfortunately it will not give any warning signs, at 102.4 It might boot Fine and show no ill signs, but then raising to 102.6 all the sudden it might no longer boot, and then you might find when lowering it back to 100 It still might boot because the installation is now corrupt, so just have your data backed up. (And you can't count on a SKU being safe because of tolerances within silicon. So someone might report that a 970 Pro is fine with BCLK Overclocking, but because of Silicon Tolerances one persons 970 Pro can tolerate BCLK OCing just Fine, while the next persons might become Unstable and Corrupt the Drive under the same BCLK, so just be backed up before playing around just to be safe.)

Spoiler!


Anyways, didn't mean to make that so long, I am extremely envious of your OC, it looks to finally be performing like PBO Should be, so its good to see someone pulling actually awesome numbers out of it!
