https://steamcommunity.com/app/223850/discussions/0/598527307801480746/#c598527452475617102 The dev of TimeSpy says the 5090 or 5080 can cause CPU overhead issues and not to use it. Rather Steel Nomad is better choice. -
Joined in. I have better luck in RU.efi doing below: Alt-F to enter menu bar Choose EFI Variables and then the scroll to the EFI Variables -> Setup Use Control + PgDwn to get to proper addresses. Control + w to write before Quit and reset.

Checking my settings in RU.efi the eGPU root port was already set. I did the 2080 RTX disable, PEG and internal Gfx disable.

From cold boot the 5080 has incorrect PCIe settings. As if the BIOS picks a "bad handshake". The only workaround found is to allow boot to Windows. Disable, unplug, replug the AGA inside of windows. Then stable connection is established. You can see all the screenshots and progress in the AGA thread. What stinks is that if I leave the AGA plugged in overnight with the laptop on suspend or hibernate the system crashes. Comes up cold boot.

I set the max for all cores to 47x in OC BIOS settings. Then did this under-voltage:
-
"0C80 = 3200, 0xA63 as 80 and 0xA64 as 0C"
-
9900K (updated since rolled back to 1.3.2 BIOS and needed CPU without later e-fuses burned) 64 GB RAM at 2667mhz (don't try and code in 2666) 1.9.3 BIOS update since trying to fix AGA 5080 RTX "bad handshake" PCIe defaults. Still have to unplug/plug in Win10 to work.
-
I was on 1.3.2 but updated to 1.9.3 to try and fix the bad BIOS handshake with the AGA 5080 RTX. No improvement.

Post pics of the swap when you do it!

If you are just doing 2667mhz do not enable the "MEMORY PROFILE 0XA65 → 01" I think that is XMP and not supported for some DIMMs.

What size shim? Where can I find it? -
0C 80 but you got methods to recover your NVRAM/BIOS chip right? 0C80 = 3200, 0xA63 as 80 and 0xA64 as 0C Dude above knows way more settings that me but like I could not get the CL settings to be "hard coded" IMO the DIMMs have SPD read values of CL. Still no direct reply to this: ✅ Memory Profile: MEMORY PROFILE 0XA65 → 01 ✅ Additional Overclocking: 0X93F → 0B

Well I can report there is no improvement of the original PCIe handshake of AGA w 5080 on the following BIOS: 1.3.2, 1.5.0, 1.5.4, 1.9.3 But from what I've read people stayed on the older BIOS to squeeze everything out of the 2080 which I am not using anymore. Running 1.9.3 now and still using the AGA disconnect/reconnect inside of Windows to get good link.

So I've been on 1.3.2 since I trusted the feedback that is was for max perf. Now that I use the AGA for most of my performance I am wanting to solve the sometimes bad handshake. So going to try 1.5.0 version first as I am not sure I can roll back once I go up to 1.9.3
