AM4 BIOS info

I may try but i have no stability problems at all anymore and i don't see a warning anywhere that says USB doesn't work correctly when the RAM is overclocked.

Edit:
On intel i had AVX offset in the BIOS. Any ideas how to handle multi core AVX sessions?
I have a flac encoder with AVX optimization and using 20 threads bangs at 90°C pretty fast using only 142W without additional PBO limits.
Apps like handbrake video encoding using AVX run around 80°C here.

This forum is only reachable for me a few hours a day here from germany. Am i alone with this?

I have to shutdown and start again. A reboot is not enough. Ryzen Master still shows the wrong value for VDDCR if set in UEFI -> OC Tweaker\External Voltage Settings I quote myself here because i have to add my USB MX-518 mouse hung itself 2 times since the 2.00 update. It stutters and shortly after losses the key associations done in the gaming software. It is 2021 and USB simply being broken in a mainstream product is a bad joke. I regret switching to this AMD crap. I have no idea how i will be able to sell this board with this build in errors.

BETA L2.04 took 3 days before the keyboard was not detected on a cold boot.
I think this happens more often when a device is also connected on the front USB3 onboard connector.

Board model: X570 Creator
BIOS version: 3.50
CPU: Ryazen 3950X, and 5950X
RAM: Corsair Vengeance CMK32GX4M2D3600C18

Notes: On BIOS 2.0 this worked great with the XMP profile. On BIOS 3.50 in preparation for 5950X CPU upgrade, the system failed when under memory stress. I was able to manually set DRAM to 3400 / 1700, and clocks 18-22-22-22 and have a stable system. If I try to manually clock to 3666, the motherboard will not power on. After 3 failures it defaults to base speed. I was able to recover to 3400 / 1700. The voltage on XMP was AUTO. On all manual settings I use 1.35 volts.

Users have to manually activate the DDR4 settings instead of them ideally being read out and activated automatically.

Board model: B450M-HDV R4.0
BIOS version: 4.6
CPU: Picasso APU
RAM: 16

Notes:

4.6 has much improved over vendor-delivered 3.7 version, e.g. 1 mouse failed on me.

Users should be aware that a power cycle can take 40 seconds during which they might think that the mainboard has "frozen". Just be patient and wait until power-cycle does finish eventually!

UEFI explicitly states that - while in superfast boot mode - the user has to "clear CMOS" to force entry into UEFI menu in case of operating system not allowing to go to UEFI menu. Or in case of OS crash / BSOD (Blue Screen Of Death in MS OS).

Under Linux, I found this to be wrong. The DELete key even now will summon the UEFI menu, contrary to what UEFI itself states.
