![]() Temp GPU1: Max 76°, temp GPU2: Max 59° after assigning it a more agressive fan profile, should be nice no? Why is that? 140% supersampling + everything on ultra seems to run fine without jitter / stuttering. Passed multiple times Firestrike + Firestrike Extreme + Furmark benchmark + Realbench 2.0 and i played BF4! Although i had to switch back from 160% / 165% / 170% supersampling to 140% because i noticed jittering / stuttering, but the FPS were just fine. Welp, i have both cards synced now at +75, +250 and they seem to run fine without crashes. Thanks a lot for providing me such excellent answers! And thanks to all the other people too which replied in this thread here! As usual, great community! In your example sync both to +75 and +250.but max out power target for both! Then sit back and let GPU boost 2.0 take max performance to where it wants.make sure, of course, your cooling is adequate.since this will be the big limiting factor in giving GPU boost the room for manoeuvre. However the boost function looks after itself.when you sync the cards, in say Precision X, I would do it to values you know work for both cards i.e. I have heard a few bad things of the new BETA and was kind of expecting to too.guinea pig for new functions I don't want to be. That beta includes new functions not related to gameplay and is no different to the earlier WHQL in terms of performance for games.so I would leave off updating from 331.82 for a while.until you hear good things about the new drivers. This is perfectly possible without microstutter so what you were seeing is probably due to the beta driver. This is independent of any link in OC software. I just want to confirm.Īrne hates to say it but Arne is correct.:o GPU boost 2.0 can and will boost cards to their full potential and if this gives different highest boost clocks so be it. But both cards are linked and have the same OC!ĮDIT: After a reebot and now in BF4 both GPU CLOCK's are at 575 but i didn't change the OC? Is this because of SLi? Getting confused right now!Ģ: There is still a question on my mind, i've read that in sli mode it is good to have the 2 GPUS at the same speeds (mem clock, gpu clock) because theįaster one will adapt to the slower one so they run the same speeds.įor example card 1: +100mhz gpu clock, 300mhz mem clockĬard 2: +75mhz gpu clock, +250mhz mem clock.Ĭard 1 then automatically adapts to card 2 and clocks down to +75mhz gpu clock and +250mhz mem clock.Īrne stated though that different clock and mem speed isn't a problem. Well it actually did not jitter or stutter while moving the camera or moving before i installed a second 780.ĮDIT: Switched back to the non beta driver, at 160% supersampling now no jitter or stuter as it seems!ġ: Strange is that EVGA Precision shows GPU CLOCK GPU 1: 1124MHz, GPU CLOCK GPU2: 1150MHz. Once sucessfully OC'ed and stresstested put the other 780 in. Remove the 780 i have installed now, put the new one in, leave the old one out so when im OC'ing i can see if the new 780 SC ACX handles more than +75MHz GPU clock offset and +250MHz Mem clock offset. Of course i would OC the second card aswell and my thoughts of doing this are: How long would 2 X 780 last for playing games 1920 x 1080 on ULTRA? Can't speak too much about that since im only starting to read about this topic. I am afraid of microstutter though, but I read on the interwebs that Nvidia at the moment has good SLi profiles and updates them regularly. What are your recommendations? YES / NO? Why no? Upgrading to a 780 TI is not an option! I'm aswell curios to have a SLi setup for the firs time too, pure eyecandy! Im only running 1 X BENQ XL2470T at the moment, might add one in the future. ![]() I need some feedback, im really considering getting a second EVGA GTX 780 SC ACX for my system.
