Seems the new AGESA will be dropping in conjunction with the 3950X which makes sense.
Given that the 100+ features/fixes is part of an MSI marketing slide, not so sure about this one. I suspect there will be a number of additional items, not least additional menu items in AMD part of the bios however, I also reckon MSI marketing may have gotten a little over excited about the number of changes
Thanks a lot for this. I was looking for this information. If you donât mind, I will quote your reply to that thread, in case anyone else is going through it and doesnât stumble across this thread.
A question though. I see 2 separate IOMMU groups for USB controllers. Does this mean that I wouldnât need a USB PCI-E card ?
Blockquote
IOMMU Group 23 08:00.1 USB controller [0c03]: Advanced Micro Devices, Inc. [AMD] Matisse USB 3.0 Host Controller [1022:149c]
IOMMU Group 23 08:00.3 USB controller [0c03]: Advanced Micro Devices, Inc. [AMD] Matisse USB 3.0 Host Controller [1022:149c]
IOMMU Group 35 0e:00.3 USB controller [0c03]: Advanced Micro Devices, Inc. [AMD] Matisse USB 3.0 Host Controller [1022:149c]
Yes but it may be trial and error to find which ports. Every now and again I find these go to headers on the Mobo which I havenât used! Haah
So I have to order a USB header
From my testing IOMMU group 35 is the white port labeled âbiosâ and the blue one next to it. Group 23 are all the other USB ports it seems.
Despite the good groups now, there seems to be a bug in the bios/agesa and passing through the USB controller in group 35 will freeze the system immediately. I spent an hour or so troubleshooting this and all I managed to get was hard freezes (no logs, no nothing) the moment I launched any VM with this USB controller attached. With one of the ports connected to it being labelled âbiosâ (for the flashback feature) maybe thereâs something odd going on with it.
WaitâŚdoes this mean using USB PCI-E card can be avoided ?
Also, the USB-C on RTX 20 series cards can be passed through, right ? Wish Navi also includes USB ports on their upcoming cards.
AwesomeâŚBtw, doesnât this MB has USB 2.0 as well as 3.0 ports ? Why group the USB controllers together, I wonder.
Can you please also test whether this x570 Aorus Master MB has rdrand (random number generator) issue or has it already been patched through BIOS update including the microcode fixes? This wouldnât take long
Iâm still trying to figure out whatâs going on with the USB controller, but Iâm fairly certain something isnât right with the bios. Hopefully an update will fix this.
The author of this article misunderstands how one off bioses work⌠this is technically an Enterprise product which takes a long time to qualify. I agree itâs frustrating to wait so long for an update but an assumption made by the author â that any new bios made after the fix was known would have the fix â is never a safe assumption.
Even our own users here were told the update had the fix, but it didnât.
I didnât have any proems with Steveâs build but only because I verified what changed I the fixed bios posted here.
All consumer boards that have the abb+ agesa and newer smu will have the rdrand fix. Itâs not the date that matters, but the agesa, for this particular issue.
It is a bit disappointing it was fumbled but this is not a typical in the Enterprise. Iâve ordered over a million dollars of kit that wasnât actually fully usable for 3 months because we were an early adopter and the stake holders decided the payoff of being an early adopter was worth the risk.
For a while I had a similar issue and fixed it by plugging keyboard/mouse into different USB port. Kinda weird I know however, it worked ⌠so that was nice
