ROG STRIX Z790-E GAMING WIFI BIOS 1904

I just updated and all seems good

Which manufacturer produces 64GB DDR5 DIMM modules?

EDIT: OK, thanks, I found that Kingston has released some 64 GB modules too and Samsung has released 128 GB DDR5 modules.

Micron, for one. Early doors in terms of validated kits for enthusiast products.

if anyone is on 13th gen cpu dont bother updating to 2001. no performance uplift. actually performance downgrade for me. went from a 25600 to a 21000 in timespy cpu test. that was nuts. flasehed back to 1904

CMO profile from 1801 loaded and saved fine. No BIOS hang.

Quick test in CPU-z show same or slightly better CPU performance, but only few points in MT.

I noticed two new options. :

USB Host Controller Support [Disabled] -> probably related to Thunderbolt 4 support.

PCIe Bandwidth Bifurcation Configuration [GPU + Nvme M2] -> which is x8 + x4, used to be x16 or x8 + x8

did they fix the WHEA error of PCI-E lanes? I have latest firmware with my samsung ssd and that didn't fix the issue for me. I believe that is asus mb issue.

[inge70]

Did the WHEA error exist before or only since the BIOS update?
Which Samsung SSD is it exactly?

[storaid]

thunderbolt function still sucks..

[Galixte]

Which motherboard? Which Thunderbolt issue?

When you connect any device, such as a dock, to the TB4 port, it runs perfectly after the initial power-on and device initialization.
However, once you restart, there is a high likelihood that the device is lost and cannot be found forever unless manual power-cycling.
Tested 1801 and 1904, all had the same problem.
I have tested the following devices:
1. OWC Thunderbolt Go Dock(OWC Tech Support told me that's not its problem)
2. BENQ DP1310 USB-C Docking Station

I am currently in ongoing communication with ASUS Tech Support regarding this issue.

I had a weird issue just now. Booted PC to Windows and in SIVX64 said it cannot detect DIMM temperature sensors.
I never seen this issue on my PC.

When restating I got black screen and PC hang. I did PowerButton override and system booted after 30 seconds to BIOS in Safe Mode.
I loaded my BIOS profile again, just in case and saved. It said no changes were done. I rebooted again and it did boot OK to BIOS after 30 seconds black screen.
And then to Windows where DIMM temperature sensors worked fine.

I wound say BIOS 1904 is suspicious, reminds me the broken 1402 BIOS.
