Here's my experience, it's not extensive, this is from a standard user just playing around with the XOC BIOS on the card.
I seem to have dropped in performance from the "OC" switch BIOS(original one) when going to the XOC Beta BIOS, from this forum thread. Let me try to explain it.
I am using an in game benchmark and from actual playing experience to determine my early findings. The game is The Division 2. I made changes to the graphics to full ultra, DX11(12 kept crashing), Vsync off, 1440p. My FPS avg with the original OC Switch BIOS was 127 within the benchmark and in game actual gameplay, around 120 to 125. My X1 settings are as follows: 500 VRAM offset(10k mhz), 100 core clock(maxes to 2070 in benchmarks and in game), 100 on the voltage, and temp and power target sliders in-sync all the way to the right.
With the XOC Beta Bios, no changes to the in game graphics and settings, is now 88 FPS inside the benchmark and around 85 in game actual gameplay. My X1 overclock settings are the same as above.
For sh and giggles, I did an almost default run(0 mem offset, 0 core clock, 0 voltage, 118%/91*C pwr target and temp slider all the way up. My results were exactly the same as mentioned above. Umm, what?
Here is the rest of my specs of the gaming PC:
8700k OC to 5.1ghz(AIO)
32gb G.Skill Trident RGB RAM @ 3200mhz
3080 FTW3 Ultra(mentioned above)
Game is loaded on a WD Black NVMe 500gb SSD
MB: Z370 Asus Rog Strix E-gaming
PSU: 850w EVGA Nova G+ 80+ gold cert
I don't think this beta BIOS is for me. I am losing performance in a game that I play often. I haven't tested any other games but I can't imagine the results to be that different.
My million dollar question is: How can I flash the Stock BIOS back to the GPU so I can re-adjust my OC settings on the OC bios switch to where it was BEFORE I loaded the Beta XOC BIOS?
I appreciate anyone reading and dropping their feedback on my comments above.
Edit 1: I'm leaning towards my PSU isn't beefy enough for this BETA BIOS. I think with the voltage slider all the way up to 100, it's taxing it to it's brink. I'm guessing here. Please don't roast me. I can't think of any other reason as to why performance would go down with the same OC settings as I had prior to loading up the XOC BETA BIOS. I'm perplexed. Ok, I think I'm done...
