hi guys, i just bough a zotac gtx650 ti synergy and i would like to oc it using firestorm and i wonder how much it oc it can take without increase in voltage?

base gpu = 928,mem=1350,base voltage = 1075, if max voltage to 1150 it can be gpu 1150/mem 1600 (taken from a site) but it wont last for long at maximum voltage right?

update: as i tested at 1100 the temp is ~57-60C, at 1125 temp is become 69, is it safe to keep for 24/7 use??

To be honest I've been having trouble working out exactly how to keep this card happy. I seem to have found the perfect balance though, and for the record, it seems to be the Memory Clock that causes instabilities for me. If I try to push it any higher than 1423MHz, it throws a fit and kills the driver causing the OC to reset to factory settings. I tried pushing the GPU clock past 1180MHz, while keeping the Mem Clock at 1400 but it crashes when the GPU hits 1200MHz so I've decided to stick with what I've got. The links in my other post are now invalid as I deleted my older results, new links are now in place showing current scores and card settings.

i tried to make it to just 1070/1500 no vol increase and it work fine for 1hr playing bioshock, but crash right after 5 mins playing tombraider, so i guess its not stable at all

btw isnt oc from 928 to 1300 is a little too high? i dun think that card could get to that point.

thanks a lot @AdmiralDonut :D
i heard that GPU clock gives more than memory clock is that true? i kinda always have problem if i push the gpu clock more than 1100 but also keeping memory clock at 1550, guess the mem clock is the problem

i wish i could do like urs, but tombraider(which is AMD card prefered) crash whenever i push the gpu clock over 1100 XD but the memory clock then fine with whatever lower than 1600, weird thing. i guess i should keep it equally to match the ZOTAC 650 Ti AMP edition (100 and 200 higher) and it gives me ~10 more frame without pushing max voltage.
thanks for ur help :3
