post #12891 of 38701
With the new 12.6-12.7 drivers is anyone else experiencing grey screen while surfing the web? I'm currently running two profiles in Trixx on my 7970, one which is 1200/1800 @ 1.3v and the other at stock clocks/voltage. The overclock profile runs fine in games and benchmarks but crashes while browsing; I have to switch profiles when wanting to browse the web. I was wondering if it's just the new drivers or if there's a work around?

The pass few times I've played BF3 my core clocks been at 500 MHZ, other times it was fine, not too sure what's up with it.

It's known problem and it's the Flash, indeed. While in game, press alt+enter, close the particular tab, close and re-open browser, re-enter full screen mode in game, done.

Where is that Flash thing you have to disable in IE?

I cannot seem to find it at all.

Thought i was on a role with all the changes i had made and BOOM! BF3 Crashed on me last night.
Mind you im only playing via campaign through the BF3 shortcut, not going through the IE - so im not sure as to how the flash would still affect it, unless it runs in the background regardless IE open or not... but i have run out of ideas and have done everything i could find...BF3 and heaven 3.0 the last 2 things that crash on me....

Tested Mass effect 3 - OMG - looked awesome!!! only in some cut scene's did it drop to 33FPS - during game play first level was staying in the high 50's. 2560xRes, everything on high.... looks amazing!

Heaven still crashes on transition stage 5 - 6........ still very strange....

Hey guys, my default voltages are 0.993. Does this mean I have a lot of room for overclocking?

You may, but then again, you may not. You'll have to try and see...

Hey guys....

About to start OC'ing my two 7970's

Where should I start, I don't know much about AMD cards to begin with.

It's pretty simple right, just max the voltage slider, then up the core 20 Mhz at a time until I crash in heaven. Then lower the clocks accordingly to most stable.

Repeat with memory, 20MHz at a time.

Combine clocks, and voila?

I dont think my card can even run 1300 in heaven.......
post #12898 of 38701
Also, how do I clock both cards individually without physically moving the cards into the first slot?

Too bad you don't have a Maximus board. On my Rampage I can just turn off the PCIE lanes that I don't want to use so I can just switch between the two cards at will. As far as OCing goes, I like to test each card individually moving up in 10MHz/mV increments and finding max clocks for each mV step. Most 7970's will do 1125MHz at stock voltage so that is where I always start. Set 1125MHz and leave voltage alone, then run Heaven all the way through. If it passes, bump it to 1135Mhz and so on until it crashes. then bump the voltage 10mV and repeat. Do that until you reach a clock speed that won't pass at max voltage and you have your max core speed. Then you can start dialing in your memory. I use 1650mV on the memory and that is usually good for 1600-1750MHz on the memory.

Once you get a max stable clock (core and memory) for each card you will know which is the weaker of the two and you will have to set up your CFX clocks with that weaker card in mind...




Oh, also forgot to mention that one of my 7970 OC's was indeed open box so I have put in an RMA request to Amazon. I hate to return it but I paid for a new card, not a return item. My RMA is already approved so I will hopefully get my new card by the end of the week...

Thank you sir.

I created a thread before you answered lol wink.gif

But I still have some questions.

Thanks...
