OC causing driver crash

[SolOS]

So, I have my GTX 960 clocked to 1550mhz and tested it by running fallout 4 for 5 hours with zero issues. Max temp I've seen is 56c. However I later tried running furmark and got a near immediate driver crash. knocked it down to 1510mhz and same thing, 1480mhz same thing. The card boosts up to 1436mhz on it's own which works fine in furmark, but applying any amount of overclock leads to crashes in furmark even though I see no issues in games. Any ideas what could be the cause?

Is it trying to boost beyond your overclock? Perhaps furmark is causing the boos clock to go far too high.

Have you tried adding voltage? Also, out of curiosity, what's the ASIC quality of your chip?

nope, monitoring it and it's staying right at 1550

Yeah, i have bumped up the voltage, maybe I need more? how much is considered safe? where would I go about looking that up? it's a gigabyte g1 gaming gtx 960 if that helps

Stock GPU BIOS's don't let you push the voltage to unsafe levels. I have my 970 maxed out to +87mv or something. However if you have a custom BIOS that can push more voltage, that can be unsafe. In short, you don't have to worry about it unless the temperatures make you uncomfortable.
