980ti.....crashing system in certain games

[phatboy]

Hi all,

So I sold a guy at work my old EVGA 980ti SC+ and he has been having issues where the card is fine running PCARS and he can successfully run full Unigine Heaven / Valley bench mark no problem at all but.......

Grand Theft Auto 4, NKB 2K19 and NFS 2016 all run for a short period and cause the machine to reboot.

The card has been faultless in my gaming machine for the last 2 years, so I would be surprised if it was the card at fault...obviously you never know though

Any thoughts on what could be causing issues here? or seen similar issues?

My first thought was PSU power issues, for reference he has either a CX 650 or 750 in the machine.

Thanks

Ben

Thanks for the reply

Yeah I heard same about CX but it's high end model so you would think it would be ok tbh

Going to test the card tomorrow on my rig at work and try see what's what. Just wanted to get any ideas I can upfront

So!

Card has been thoroughly stressed and tested on my rig at work using need for speed, NBA 2k17, fault free 12.5k firestrike run along with pasmark etc. Didn't miss a beat for nearly an hour. So looks like issue is down to his machine sadly.

He is running a 2600k sandy bridge system and currently has a reference 980ti in his machine and 970 in his sons machine, they are both similar mainboards and both give same issue which does lead me to believe that @Kei could be on to something with it being something BIOS setting related

typical psu sympton described.

what was his old card? what is his psu?

Reference 980ti in his machine and he has a cx750

I got a new 700w PSU a few days back in the rig I tested in today, I have loaned him it to take home and try tonight as we know that handles the card fine
