7970 overclocking NEED HELP PLZ! ty :D

7970 overclocking NEED HELP PLZ! ty biggrin.gif


ok so i just bought this thing new today. i been playing with clocks and such I am not new to overclocking but I am seeing some reactions here that I can't explain.

first why is it that my card with 1200 core and stock memory is not much different then 1200 core with 1600 mem???

i would think i would see a big gain for that boost in oc. but its not working that way.

second, the card at 1.15 or 1.125 can get stable but to push it to 1.25 or 1.3 with same clocks or even stock clocks won't run just goes to black screen like insta.

normally i understanded that raising the voltage INCREASES stability and again I am seeing the opposite. could it be my card just doesn't like to run with that high voltage? is that a bad thing?

third and final thing. I notice with 1200 core and playing with 1550 or more on memory with 1.5 volts the core clocks stutter / jump around according to msi afterburner chart but with no memory overclock and 1200 core its a solid 1200 on the core all the time.

is the jumpy / stutter in core because of instability?

and suggestions how to reach 1200/1600 or should i just run a solid 1200 with stock memory. will in game fps be much different cuz in furmark its like 1-2 fps off stock mem vs oc mem

help is lovely thanks yous.

What 7970 do you have? At those voltages i suggest you check your temps

my temps never hit over 70

i have the gigabyte oc card.

I don't know if you realise but you should aim for the lowest voltages which are 100% stable with your clocks tongue.gif If you raise them too much it will cause intability!

You're quite demanding. Memory does not effect your FPS/Benching nearly as much as core does, 1600 on memory seems like it should be stable pretty much no matter what card you have. In OCCT I see gains of maybe 10-15 frames between stock and 1750 memory which is the grand scheme of things isn't a lot at all.
