So....
I have installed the new 3001 Asus bios on my ITX X570 Motherboard.
Initial tests are really promising, although please note that this is the strangest update I have ever had on an Asus board. The bios update itself restarted the machine 3 times to complete various update steps (inc the LED lights firmware).
Please note: Once updated, you will need to reapply PBO via Ryzen Master as the settings won't stick even if they were successfully applied before, so please do re-test and apply PBO if that is something you want.
My own testing shows no WHEA Windows Cache Hierarchy faults, and the machine does not do the strange idle reboots like it did before. XMP/DOCP also seems to work. Scores in Cinebench seem very good once PBO is re-applied (scores over 27K consistently assuming you kill most background programs). Boosts have gone up to 5Ghz, but not quite as good as when I set some voltages manually myself where I was closer to 5.1. CPU temps seem to range between low 50s and high 80s with my current cooler setup, but I am upgrading from a 240mm to a 280mm cooling setup in the next few days so hopefully that will help lower these. I believe AMD when they recommend an AIO for these new chips, although I suspect some of the high end air cooling solutions might also be good enough.
Those of you thinking AMD had messed up big time and that a bad batch of processors were sent out to a lot of customers really need to try these new BIOS that are starting to come out from the board partners, as they honestly seem to work. It was pretty obvious reading between the lines reading all the forums out there that a lot of this seemed to be down to the way voltages and other settings were being handled in the background, rather than fundamental flaws with a chip production batch. Obviously an hour or two of testing is not the end result, but I would say this is a massive step forward as I know the older bios would have had me blue screening in minutes on basic web tasks, let alone anything more creative.
The only thing that is still buggy appears to be the LED Aura settings which don't always survive a reboot. That's an issue that seems to be infected the last 2-3 BIOSes from Asus, and I don't see this as a deal breaker myself, although it would be good if Asus fixed this. it's clear Asus testing team are not always up to the task, but at least the more fundamental issues seem to be resolving themselves.
As always YMMV, so keen to hear what others think about these new BIOS versions and how positive (or negative) your own experiences are. Personally I am now pretty happy with this 5950X based on these updates.
