whats ur powersupply also why did u mix up 2 different gpus u know that wont run in sli right.

agrecascinoq · Dec 12, 2013

And before you get on me different gpus I'm using different sli and hypersli

iceclock · Dec 12, 2013

i dunno what u mean sir, but those 2 cards arent compatible for sli. u need 2 exact cards for sli. but u can use the 660ti as a physx card and the 770 as ur main card, also sir whats ur powersupply its possible it may not be strong enought to make both work.

thank you Joe

Psu is thermaltake smart m 850w

your powersupply got good reviews

so that shouldnt be the problem, when did u buy the videocards?

also did u attempt to put the sli bridge between them?

agrecascinoq · Dec 12, 2013

FYI: differentsli is a driver patch that allows gpus of the same core to sli gtx 770 and 660 ti are both gk104 therefore this patch should function

agrecascinoq · Dec 12, 2013

And the sli bridge is on as I tried with or without

agrecascinoq · Dec 12, 2013

Gtx 770 is almost brand new gtx 660 ti is year old

iceclock · Dec 12, 2013

i still wouldnt recommand it, might be creating your issue.

also when did u purchase this 770 might be defective

agrecascinoq · Dec 12, 2013

770 is currently my main gou

agrecascinoq · Dec 12, 2013

770 is currently my main gpu

iceclock · Dec 12, 2013

ok well have u tested the 660ti as a maingpu and does it work?

worst case maybe u need to just use the 770.

agrecascinoq · Dec 12, 2013

Both do work but it seems that the 660 ti acts like it doesn't exist

iceclock · Dec 13, 2013

well if its not detected in windows i doubt it would work, what u mean doesnt exist.
