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
 
The machine just plain rebooting under heavy load would almost certainly be a PSU issue IMO, especially if you know the card is good from having it in your own system. Although the CX series isn't the absolute worst out there, and I'd expect it to be able to handle a 980 Ti at those wattages under normal circumstances. Could possibly be faulty or overheating though.
 
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
 
Not necessarily the psu or the card. I had these same symptoms of sporadic rebooting with particular games with my GTX 780 and the cause turned out to be having intel vt-d enabled in the bios and windows 10 past the creators update. This was on the x79 platform with an ivy-e cpu. Not sure if it affected any other intel platforms but it is certainly worth a look.

It does show that these symptoms aren’t always hardware related. I tried everything and it all pointed to a faulty GPUs as swapping it out for a spare amd card stopped the crashing. Figured it couldn’t be the gpu after fitting it in an old amd fx system and it worked flawlessly.
 
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

I don't think a 2600k has vt-d, only vt-x which in my case had no effect whether on or off. Might be worth making sure the bios is at the latest version. Trying a known good PSU is always a sensible idea too just to rule it out.
 
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
