so for the first time i've tried to overclock my gtx 580 twin frozr 2

i changed the settings as follows

voltage core memory

1050 - 1100 800 - 900 2048 - 2099

at first it worked great giving me 5-7 fps increase in GTA 4. then however it bluescreened and i had to reset. so i tried again setting the speeds as follows

1100 850 2048

bsod again

1050 830 2048

bsod again.

why am i having problems getting the slightest bit of overclocking from my gpu? is their anything i can do because i don't want to keep bsoding my card. thanks guys

if you truly what to overclock your card it will take days to get the best overclock for it, not just punching it numbers and hoping it will work.


ALWAYS KEEP AN EYE ON CARD TEMPS WHILE DOING THIS

keeping the stock voltage bump the core clock from stock up by 5 points and run a benchmark, I use 3dmark 11. If it works, great, bump it up another 5 points and repeat the test. keep doing this till it cant finish the test, once it cant finish the test bump the voltage up a few bumps. Then continue bumping the core speed up, you will get to a point that you run out of voltage or cant raise the core clock anymore without failing the benchmark. Once you hit the max speed for core clocks write it down and return the card to factory speeds. Start the process all over again but this time raise the memory clock instead of the core clock. Once you find the max for both core and memory set the card to these then move the core speed down by 20 and the memory down by 50, run the benchmark or test and see if the card is stable. If it is great slowly more the core up by 5 run the test then move the memory up by 5 and run the test, keep doing this back and forth till it fails. If you move one at a time you will know which one causes the issue when the card fails the test.
