Hi everyone :)
I bought a used 1080ti SC to assembled a render machine
The guy told me already there was some issue with artifacs while playing but not overheating
I repasted the GPU with Grizzly.
I keep the thermal pad original.
Because my PSU is a 500w NOT MODULAR I bought a SATA to 8 PINS adapter, which I think can lead some problem
The PSU have a 6-8 pins (the one with 2 pins detachable) on it so i put the 8 pins from SATA adpater and I connected the 6 pins from PSU
Until I was in desktop remote and using the Microsoft driver adapter was fine
Really low temperatures (21 degree)
When I attached to a screen begin to have really weord artifacts and freeze with the classical green line from overheating.
Infactt was really hot
I unplugged i let it cold and after I try again
Was good until i haven't update the driver
Again the same thing
So I think the OC factory is too much, also I don't need it, I need CUDA CORES not mhz so I could underclock without any problems
My question is could be overheated because the SATA-8PINS adapter?
I ordered a molex to 6 to be more sure, but you think I could have done some damage?
I have also ordered new thermal pads in case
Thanks

Yes  with the X1 software manually i put at 100% from the begin
The 2 time was really hot there was not X1 installed
 
So could be a combination of 2 things, psu and stock bios
There is a bios can replaced the stock one?
 

No idea what part of the world you are in.
 
Register the card to your region & send an email requesting the correct BIOS for you GPU
 
Please contact EVGA support team at support@evga.com with the serial number to your graphics card so that they can work with you directly

You think can help me also if the GPU is used?
I'm in Italy :)

Please make sure you have registered your product with EVGA at: EVGA - EU - Support - Product Registration
 
Then email the serial number and concern to our German office so that they can work with you on a solution.  SupportEU@EVGA.com  
 
However the first email is the EVGA Headquarters in California, USA .... so expect delays as they 8? hours, behind your timezone
 
Register as second owner, in EU ..... (the email address that you use in registration is where EVGA will reply to you) & request the BIOS file

Please do not use a SATA to 8-pin adapter.  SATA is the worst option you have.  At least use 4-pin molex to 8-pin adapter instead of SATA.

I got a proper psu.
But what about the bios?

Contact EVGA in the EU. Please note that they do not work weekends.
