Sounds funny, since PBO needs a reliable running RAM, but wether ram encryption is enabled or not, sounds like undefined behaviour for me. Where u looking at to see if the power levels have changed?...

Had the same problem some time ago, I thought. Pl0x try some heavy gpu burning first, not game testing only. I know it sounds derpy, but try refitting the GPU power cables, on the psu, too, if modular....

So, 36d for x570 Xtreme vanished from uk supprt site. May this be the sign for us to await the non-usb-****y-bios?

What do you mean by that? I never used the second bios, even when it would be faster to test. But I wont switch the profiles. PBO under 2.0.0.7 is kind of good for me. But I wasnt sure if the old bios may have some impact on the newer one though it is disabled through switch.

Regards...

Since 37d I have laggy keyboard again, so sometimes double printed chars. I disabled duo bios via switch, should I nevertheless update the second bios?

For me, setting PCIe to 3 fixed the usb errors partially. My mouse and usb dac is not lagging anymore, I can life with that till April. On the other hand, AMD could spend us some amd 6900 xt, that would be fine too.
