Have you already made any memory related changes in BIOS? Have you tried reflashing? Maybe to one of the latest versions here like 0081? What memory configuration are you using?

Nope this was done right after cleared the CMOS and I flashed to 1002. I have 2 x 8GB Corsair Vengeance 3200 mhz and I just tried to boot with only one of them and still stuck on 0d

I also tried using the slow mode switch but it didn't help

It's very unusual for the training to fail on default / stock. I guess you already tested all DIMM slots? I'd really try to flash one of the latest test images here, otherwise theres not much advice left for me to give you. Any possibility to double check the memory in another rig?

Which slots should I test? Or rather which configurations? Or should I just put in 1 RAM and try all 4 slots? I could test the ram in my old rig but they worked an hour ago so I don't think it's necessary. Also by flashing one of the latest images do you mean flash the lates bios? Or is there a way to import settings without getting past post?

I'd also like to try and clear CMOS one last time so how do I actually do it properly? Hold it down for a certain amount of time? Cable plugged in or not? So far I just unplugged everything and hit the button

When RAM training fails and AMD CBS resets with Extreme Tweaker having offset value you end up at crazy voltage frown.gif .

I've had it 3x, SpecChum, Ubardog and others had it more times than me and earlier occurrences in ownership than me.

This is how I know it will happen for sure, power PC > mobo boot > weird chirp straight away from speaker > mobo power down > 3x boot loop > enter UEFI = ~1.5V frown.gif .

Normal boot is power PC > Q-codes happen 1x > clean beep from speaker > enter UEFI all is well.

If it has "borked boot" I switch power off on PSU at bold/undelined stage, press CMOSCLR on rear IO and then restart rig. Then use my saved profiles to get back. I have a base profile with no OC but say fans, onboard devices, etc. Then load next profile base + manual voltages on extreme tweaker except CPU = [auto], then after reboot I load base+voltages+3200MHz, then after reboot 3.8/3200MHz profile.

So changing the soc for me was not good, made no difference and 1.17625 gave me an error f9 or f8 error after pressing reset. Went back to 1.15 and changed ram boot to 1.50 made no difference either. Still needs 1 reset hit to start up and boot at 3200mhz so not sure how to fix that, maybe less soc but i doubt it. Kinda lost but it works somewhat lol.

I set memory voltage to 1.35v as specified by my kit, and save and reset...

I was really thinking, c'mon this a new bios 0083 and my good ryzen is going to be good guy today wink.gif

But that's not how it wanted to play it.

The next boot failed 3 time in a row, and on the 3rd time went into the bios.
Then I've seen Core Voltage at 1.55V, and I've quickly plugged DMM to see it was going up to 1.573V !!!
I've checked the CPU Core voltage settings, and I could see it on auto but with CPU Core Voltage Offset of 0.2000v.

I've changed it back to 0.19875v (what I've configured previously), and then save and exit (keeping the DMM plugged to make sure it wouldn't go crazy with volts?).

System rebooted and went with a 54 error code with volts at 1.18v on DMM

I've rebooted the system again (keep power button pressed for 10sec, and then turn on again) and system started and shown message: "Overclocking failed".

I went back into BIOS and all settings look like default, so I though that ok, I can just reboot.

So I've rebooted keeping DMM on, and then seen the VCore going at 1.547v again eek.gif

Shutdown computer -> pressed clear CMOS -> restarted -> all back to normal, and now I'll play with memory only, going one step at a time wink.gif

Lesson learned, always keep DMM plugged in after changing BIOS settings thumb.gif

Dont think something special happened here. Your dram training failed and you entered bios with stock settings. At stock the volts are showed ~1.55v in BIOS.
Bios is working on stock but showing your last entered values. Only Pstates pages is wiped! If you had pressed "save and restart" to enter Windows you could see that you where running
at stock speeds just with your previous set-up voltages.

This is a known bug, cause its confusing how it work right now. My opinion:

If its booting on stock after failed dram training or oc, then communicate this better when entering the bios again. (No old pre-set values / maybe a prompt message..) or
Just work like now, but dont wipe the Pstates either!

Yeah okay so the memory should be alright then. I mean test each slot with one stick. And yeah I mean flashing one of the latest BIOS from here (0082 for example) via USB flashback.

what dram voltage are you using ?

dram voltage is 1.36 and boot is 1.50

Oke, did you ever try higher dram voltage ? With these new bios version, dram voltage on 1.4 made some magic for me

@bluej511

1st CPU I went to 1.050V SOC and VCORE as needed for 3.9GHz on stock CPU clock/3.8GHz and no 3200MHz. It only did 2933MHz, this needed 0.900V. Where as 2400MHz needed manually set 0.825V which = 0.838V on ProbeIt point = same as [Auto] on UEFI defaults.

Don't know what to suggest, only way I gain 3200MHz was CPU swap.

@Benus74



This is clean install, 3.8GHz OC Pstate 0, default WIndows Profile selection not changed one thing. Will be doing benching as I did on Win 7 to see what power profile tweaks gives best performance.

@majestynl

Your post seem confusing to me.

What happens is on borked boot Pstate is wiped as you say. But let's say CPU on stock is ~1.3V in UEFI when not borked boot, with the borked boot as offset voltage has not reset it becomes ~1.3V + offset and CPU is getting real voltage of ~1.5V. I checked with DMM on ProbeIt point.
