2CPU

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

Ok I want to start on this process. I think I will first "Disabled the internal RTX 2080" This is because I never plan to use it anymore. Do I need to also do eGPU Root Port edit at the same time? What does that setting do?

Wow thanks for the tips. I will follow these when I can and report back.

I believe the very latest BIOS can only be downgraded to 1.12.0. The later (more recent) BIOS burn e-fuses in the CPU as I was unable to boot after recovery flash below 1.12.0 without replacing the CPU to boot 1.3.2. So if your R1 is on the latest BIOS you might need to swap CPU if you get blinking red Alienware head on attempted recovery BIOS downgrade.

Wow that is amazing. I need to do this!

In the past I tried to adjust the CL values but they would get overwritten by the SPD read of the DIMMs upon boot. (guessing that is why they changed from my RU.efi settings) The DIMMs I purchased are only 2666mhz max per the label. I think these are TimeSpy scores: ~21k

I am missing these extra settings: ✅ Memory Profile: ‏ MEMORY PROFILE 0XA65 → 01 ‏✅ Additional Overclocking: ‏ 0X93F → 0B Would this help my Area51m RAM at 2667mhz?

It is more like bad BIOS PCIe handshake. Re-connecting in Windows resolves it somewhat. I am on 1.3.2 BIOS and I am 99% sure downgrading below 1.12.0 requires you to swap the CPU (later BIOS burn efuse to prevent rollback)

Woo the hero is here. Sweet! I will dabble in this in upcoming months.

Thanks for your efforts. I used your posts to reverse engineer backwards to get 2667mhz on my Area51m.

Simple online search shows a few options but might need to buy the 2080 cooling setup. I have the external graphics amplifier working on the Area 51m with good results.

Anyone else running 5070, 5080 or 5090 in AGA? For some reason my laptop doesn't stay asleep and transitions to off overnight. I just tweaked some settings in the power area (I think HDD power savings not set to never was the issue). Hope that resolves as I am required to unplug/plug back in the AGA to get the 5080 to proper PCIe settings. I am hoping to just keep my stuff open and sleep overnight and wake fine.

I was really worn out with the system being "dead" for ~3 hours while I actively tried everything to get one boot. I would of rather spent that time playing Borderlands 4 so I did not put it through a lot of testing. It is booting fine now at the 2667mhz (vs 2400) & maybe works better for games but need time to check. If you have mismatched sticks then you should put the worst CL rated pair in the slot 1&2.(I think I have one pair CL17 and other pair are CL19) That way the SPD read assigns all sticks with the slower CL values. The system was crazy hot yesterday so I do see minor improvement. Maybe a "good run" will yield 83 fps? Time spy: CL17 @ 2400mhz vs. CL19 @ 2667mhz yielded 0.21 more fps in bench marking. Overall I do see more consistently higher fps scoring. Just surprising to me how little you gain with a different CPU (+600Mhz w OC), RAM capacity (+32GB) and RAM speed (+267mhz). Two fps in Steel Nomad. However, all those changes cost me nearly nothing since I resold the older CPU for more than I the faster one and extra RAM. Edit: The fps in Indiana Jones does seem a lot higher.

Yes, you made me go check it out. Summary is if you care buy faster RAM. But I did not see anything life changing from 2400->2666mhz Yielded the best benchmark yet: Time spy:
