I'm on 0082. Thanks for the hint, I'm gonna try it.

If this is in the context of new SW ignore my post.

I never changed PState 0 VID in UEFI and when memory training fail on my R7 1700 it = 1.5V to CPU.

My R7 1700 stock PState 0 VID is 1.1875V, I use offset mode to add +162mV, LLC: [Auto]. So have ~1.380V on ProbeIt VCORE point / MAX CPU Core Voltage (SVI2 TFN) 1.356V in HWiNFO for 3.8GHz OC.

My rig is perfectly stable but I experience slow distorted sound sometimes in games and just a drop from avg 70 fps to like 13 fps for a few seconds and then back to normal. I also notice in windows sometimes when watching youtube the sound will just crackle/pause a bit, sounds real annoying like a robot. And sometimes windows just freezes for a few seconds or goes blank then comes back. I have used every test program, am 100% stable, no WHEA errors, no mem errors, ect. I would have to think it is a driver related issue or one of my background programs, but they are all up to date. Any ideas on what causes this? Asus suite, corsair link, asus's sound programs (that I never use, lol), or just firefox hogging memory? Seems like I always have to kill firefox and restart as it grows memory indefinately.

Are there any cases where a 1700 would default to 1.35V for some reason? I noticed that when I switched from manual 1.35V to offset +0.2V the BIOS would remember the manual voltage and boot at 1.35V + 0.2V, but I'm not certain if that's because it "remembered" the manual voltage or if it's some issue with the 1700.

1.35V should be the CPB single core voltage right? Just like 1800X will push 1.45-1.5V at defaults due to XFR/CPB voltages being applied while in BIOS.

There is a fix for this, which I recently implemented after hearing about it on the DSLreports ZyXEL forum. It is from Firefox 7.

Open Firefox, and enter About:config into the address bar.
Right-click on the list of entries; new >> boolean.
The name for the boolean: "network.dns.disablePrefetch" (exactly as shown, but not including quotes).
The value: True

Sorry Elmor, gonna ask again: any chance to get future official BIOSes for C6H which increase actual OC potential on RyZen CPUs?

Works really fine for benching:

When I use UEFI defaults, am in UEFI and measure VCORE on ProbeIt point it is ~1.330V. I have R7 1700.

Then when in OS and have x264 load CPU, again on that same boot/UEFI defaults, CPU does 3.2GHz ACB but has VCORE as ~1.119V, but when XFR kicks in (ie 3.75GHz) I can see ~1.35V on DMM.

So from that I would assume when I measured VCORE whilst in UEFI and at UEFI defaults PB/XFR was active.

So then on borked boot when AMD CBS has reset and Extreme Tweaker has +162mV still there I end up at ~1.5V.

Yes.

As I have no tools to check what is CPU frequency when in UEFI or any monitoring data there I do not know what CPU is at.

I can only make assumptions based from other things as highlighted above.

I've never noticed XFR kicked in to be honest, but I don't think I normally have any single threaded workloads for it to be necessary. Is there anyway to disable XFR completely?

It's pretty obvious it's not the the mobos holding back the CPUs, they're pretty much reaching their limits. What I suspect we'll see in future updates is memory stability with higher overclocks.

I don't understand why you insist on asking this question so often.
