First run is stock 920/1150, Sapphire OC edition
Second is 1100/1500 @ 1.175v
Should shed some light on the Core clock vs memory clock fps question.

With the volt that low in the safe zone I think i'll call it a day. My card isn't very core clock friendly but memory clock it seems to be okay with to pump up.

Random question, but in CCC what are the highest clocks you can set it to for the 7870?

Have not had time to do much with my 7870 yet, but I got a HIS IceQ X version, after gathering that it was the quietest version from various review charts. It is indeed extremely quiet and runs very cool (29C idle), so I am very pleased so far.

Hello, I have a problem with overclocking my HD 7850. First of all, I didn't touch the voltage nor I intend to.

I tried setting core clock to 1050MHz, memory clock to 1450MHz, and power to +20% and I got some weird blue screen with vertical stripes as soon as I entered the game (Prototype, the actual game, not the menu).

Then I tried 1000MHz / 1400MHz / +20% and the same thing happened, not as soon as I entered, but after about 1 minute of playing.

Can anyone tell me what happened and why? The computer didn't freeze completely, I could still hear the sounds from the game, but the computer seemed unresponsive to keyboard (Ctrl+Alt+Del, Alt+Tab, Alt+F4 didn't do anything, at least I think because sound didn't change).

i get the same thing when i overclock too high you need to increase your voltage or lower your clocks.

If I can't go from 900 to 1000 without touching voltage I won't even bother. Must admit I'm kind of disappointed after hearing how good they overclock.

What is your default voltage?

BTW saying you don't intend to increase voltage and then expect a good overclock is pretty silly.
