My card is 100% perfectly normal as if nothing happened now @ 2012 Mhz core, stock voltage and +700 Memory. It just won't run the 2126 @ 1.200v anymore that I previously could run with the XOC bios. And I can not clock higher than 2012 Mhz with the stock bios. Anything higher crashes the driver.

Like I tried to tell you, most stock bios's for reference-PCB board 1080 Ti's will not let users increase the voltage at all. This is standard for almost all reference-PCB 1080 Ti's. It's Nvidia that was intentionally trying to lock down the voltage. This is what Nvidia does with their video cards. No one with any 2080 Ti can increase the voltage at all as far as I'm aware for example. The only ones that let us increase the voltage for 1080 Ti's are the custom-PCB cards typically. And even then they're usually limited to around 1.087v - 1.10v You can change the voltage -DOWN- and under-volt it but you can not change it -UP- to increase it. The XOC unlimited bios is the only bios that allows anyone with any 1080 Ti to raise voltage above 1.10v. I'm pretty sure of that.
Hi there

I would rather say, on stock BIOS we are limited by 1.093v voltage, only XOC BIOS allows us to to run higher voltage than 1.093v, this is probably biggest difference


I'm still running stock EVGA BIOS on my GTX1080Ti with 2113MHz and 1.07v and no issues, with 1.093v I have run 2126MHz and 2164MHz which are stable but temperatures cannot be higher than 33-34°C if they're higher profile/clocks 2164MHz are unstable for longer periods of time and therefore I run 2126MHz profile,I think there is still bit more in clocks, maybe something around 213x-214xMHz didn't tried push clocks bit higher

You have been unlucky with yours Ti that's for sure, I told you that last time and still think yours EVGA is dud like my Zotac RTX 2080Ti right now which wouldn't OC beyond 2115-2130MHz and still that's with 1.093v and many on RTX 2080Ti thread would OC well above 2160-2175MHz and in better case 220xMHz is possible

Most of GTX1080Ti what I owned or tried they most of them will OC beyond 2100MHz under water, Aorus Extreme GTX1080Ti this wouldn't OC beyond 2088MHz and MSI GTX1080Ti Gaming X wouldn't OC beyond 2088MHz too

Hope this helps and good luck there

Thanks, Jura

Did you tried run 2126 with XOC BIOS and 0MHz on VRAM or downclocking VRAM by - 200MHz, Micron memories aren't very consistent this has been confirmed by many OC'ers and have borrowed RTX 2080Ti from friend which would start showing space invaders at anything above +200MHz and then started to showing up again at stock VRAM speeds etc and only cure has been to downclock VRAM by - 300MHz and more

Hope this helps

Thanks, Jura

that reminds me... these cards have different bios, i should probably sync em & test before tossing out one of the cards.

Add me on Steam, same name

If something appears too good to be true, it probably is.

I don't want to -decrease- performance below stock with this card ever. Right now it runs 2012 core / +700 ram and it's so far stable. At worst I will only ever drop it down to stock ram speeds of +0 Mhz. If for some reason some day it never runs or crashes at stock speeds then I will just RMA it back to EVGA before I would ever consider running it -300 Mhz ram below stock speed. It's still covered under factory warranty for another 580 days for me. Thanks for the suggestion but what I have right now works and I'm happy with it as is and don't want to change anything on it at the moment. It's only -1.8% off overall performance from where it was with the XOC bios and so I'm fine with that. And yes I know it's a dud but I don't have the money to sell it and buy another one and hope I get lucky and do it all over again. I rather just deal with what I have and enjoy it as-is.

Talk about a trip down memory lane. Sometimes I wonder if AGP w/sideband addressing had less latency than PCIe -- after all AGP was a direct, point-to-point connection between the CPU and the video card with no intervening serial communications protocol or endecs.
