problem with a gigabyte HD7950, cant even pass 1020MHz...

post #1 of 16
Thread Starter 
so, i already made a thread here, that my card crashes in 1050MHz (core) and 1400MHz (memory), i decided to set the core voltage to 1120 but nope, still crashes at 3D Mark 11 and all sorts of first person shooter games. decided to set it to 1140, nope. still crashes.

now, i've accepted the fact that i might've been screwed and i cant pass 1050MHz, so i just set it to 1020MHz and 1370MHz again.

in the past week i've been getting really annoying fps drops in battlefield 3, they're random, its not like they occur at explosions or something heavy, just random. for example, at BF3. it happens mostly at BF3, when im dead and i see the guy who killed me, my fps suddenly drops from 80 to something like 15~20, happens alot when im playing too and it happens like every 20 seconds....

i've had enough of this. i've set the core clock to 1000MHz and 1370MHz memory, hopefully it will better, but due to my soon upgrade (1440p monitor) i really need this overclock. what do you guys suggest? what can i do to pass 1050MHz? remember, even at 1140 core voltage it crashes....

Hi, is this a GHz edition card? If not why do you EXPECT it to OC that far? In order for there to be some great overclockers there has to be some poor overclockers. I bought a GTX 670 DirectCUII I wanted the TOP but it was no longer available the difference in price was only $10. So I figured I would most likely be able to get atleast close to what the TOPs where doing. NOPE can't even get a stable +50 on this thing without increasing the voltage with a modded bios.

You are not guaranteed to be able to get what you saw some review site get with an engineering sample or a hand picked unit that was sent to them.

1020MHz isnt that far... only like a +100MHz to the core and memory, plus i've increased the voltages by at least 60MHz & PowerTune to +20%.

and no, it isnt a GHz edition card, just a standart Gigabyte Windforce OC HD7950

Drop Memory to stock. Then see how high you can oc the core, before instability. Then see what you can get for memory. Core speed is more important than mem speed. If you can up the volts, do that too.

I don't know why people buy a card, and expect it to overclock well. It's guaranteed to run at stock, that's it.

Anything more is a bonus.

Yeah OP like gunderman said drop the memory to stock and then try to push the core. That said though there are no guarantees, some cards just suck at overclocking. Good luck

Quit being trigger shy and raise the damn voltage. Tahiti video cards are good up to about 1.3 volts.
