overclocking graphics card

It's safe so long you don't over do the voltage or increase heat to much to burn it out. It's also very safe to overclock without touching the voltage but how much you can increase core and memory without voltage will depend on the GPU.
 
i will give it another go with precisionx, i tried it a little already and the overall fps went up a small amount but the minimum fps went lower every time i increased the overclock, is that normal...
 
i tried overclocking again and got the dxgui device hung error, i only went 50mhz on gpu and memory, i really think that my psu 12volt rails may have failed, as the card is a evga 750 ti ftw edition, and it requires a 6 pin input, good job i bought it other wise i couldnt play anything descent...
 
What psu do you have? The power consumption would only increase by a few percent I dont see how that can take your rail out?
 
i had a zotac 780 amp edition that black screened on me after a fresh install of windows 8, i sent it for rma but was found not to be faulty, so in the mean time i bought the evga card, which requires a 6pin pcie, so i was thinking the psu cant dish out any extra, and the card is running tottally over the pcie 60 watts, but then i thought the pcie was 75watts, i cant test my psu to see if the pcie rails are at fault.....
 
my zotac was already overclocked and i think the problem may have occured with that, i am going to try a 12v molex adpter from the psu and see if it fails overclocking, then i will know...

Wht don't you borrow a psu off someone or stick the gtx 750 in another system to confirm it.
 
well i went to 75mhz on gpu and memory and bf4 crashed, the driver failed and restarted, so i think its just not going to happen for me, so i put the clocks back to normal, and still dont know if its the psu....
