STRIX B550-F GAMING WI-FI II BIOS 3607 Overheating CPU

[theonlymaverick]

Hi, 

I have just updated my BIOS version from 3202 to 3607, everything went as expected; however post update I am experiencing significantly CPU higher temperatures than previously (to the point where it is failing stress testing). 

On average my 5800X3D used to max out at 60-65 degrees during gaming, it is now maxing out at 75-90 degrees; which is causing issues with stuttering and poor performance. The cooler has stayed the same (an 240mm Enermax AIO), the only difference has been the BIOS update. 

What is worse, is that despite multiple efforts, none of the previous BIOS revisions are recognised by EZ Update, neither in the BIOS nor in Windows; so I can't even revert back to an older version. 

Running Ryzen Master, the voltages seem to be running high for no reason, even under minor load (sub 10%); I am running over 70 degrees just by typing this message.

I have tried isolating some of the background processes that were running, but it still runs hot; it also seems to boost out of control really quickly, which is concerning.

Any ideas?

If the old BIOS is not recognized, why not try resetting it to factory settings? If so, you can install the BIOS you want again. I hope that helps.

Make sure that the AIO is not about to fail.

I checked it still works; pump is still running, it isn't totally full in the rad, as it is a few years old, but still good enough, and it is in the optimal orientation. I will run it with an air cooler I have knocking around and see, though it would be pretty incredible if my AIO happens to be failing at the same time I updated to 3607

There could be a blockage somewhere (caused by gunk build up).
Then the pump will still be running but it can't move the coolant.
Does the radiator get warm/hot?

True, but possible.

[theonlymaverick]

It is possible I guess, let me to some further tests. 👍

Tested the AIO, definitely no problems there; I used curve optimiser to run a negative 30 offset and the temps are much closer to where I would expect them to be pre BIOS update, but still high. Maybe ASUS/AMD is telling me to buy a Hyte Q60 lol; I'll probably just buy a Arctic Liquid Freezer III 280 anyway.

How did you test it?

You mentioned the voltages are high?
How high, are they still in safe range?

Did you try a bios factory reset as madao1945 suggested?
For downgrading the bios, did you try usb flashback?
Also try just a simple reflash... some people actually always flash twice....

Sure, could be bios bug but if other users don't experience the same issue, it's unlikely.
Some sort of malware running in the background? (which hides itself from taskmanger)

Reinstall chipsetdrivers and make sure that the amd power package provider is installed.
Try switching power plans in windows. (to perfomance and back to balanced)

Hello again,

My wife just upgraded to a 5700X3D on an MSI board, granted a lower power chip, but temperatures were decently under control with my Enermax.

Voltages are still in the safe range, but stayed consistently at or near 1.3 volts, even when at/near idle.

It may not necessarily be a BIOS bug, it could be by design. I have seen another person reporting higher than before (1.3v) SOC voltages after updating to 3607 with AGESA version 1.2.0Ca on this exact board; so this just may be how it is. This aligns with how curve optimiser helps to reduce the temps to something closer to before.

I hadn't tried USB flashback, so I could drop it back to a previous AGESA version and see if that helps; though I have just bought an Arctic Liquid Freezer III 280mm to further rule out any AIO issues, so I will check if the new cooler doesn't sufficiently lower the temps.

Well, you can try to lower voltage to the level of the earlier BIOS?
