Prime X670E-Pro WiFi, 7800X3D, 64GB Corsair Vengence RAM (6000 CL30)

I got it with BIOS 1616 and it was very slow booting (+30 seconds), then I set EXPO and it still slow boots.

Now I just flashed the BIOS to 1654, still slow boot.  Clear CMOS and still slow boot.  Load system defaults and still slow boot.

Not sure what I should try next.

The rest of my specs are Phanteks AMP V2 1000 watt PSU, Sapphire Nitro+ 7900 XTX.

It seems to boot fine and functions.  I haven't don't any stress tests or any other tests.

Rask manager reports boot time of 58.1 seconds on fresh win11 pro install, with all windows updates and AMD drivers.

Any help would be greatly appreciated.

Are you using a secondary SATA or SATA nvme storage drive? If so try removing that hardware and boot and see if that expedites boot up. Another post I found narrowed down that to the culprit however not details on resolution if the drive needed a firmware update or bad drivers. GL.

I have an NVME 3.0 x4 SSD and a 4.0 x4 SSD.  No other drives installed.

I got it to quick boot with a BIOS tweak on retaining RAM profiles.  I found a quick video to fix the issue.

Under DRAM Timing Controls, I just set Memory Context Restore to Enabled.  Now it clears CMOS in like 15 seconds and boots windows in another 15 seconds.  So basically normal speeds.
