I would definately update to at least 12.4 WHQL for single card, single monitor.

thanks for your comment.. hmm.. it says software version 12.3

and i have a question based on the databank most of the GPU Clock/Memory is more than mine g8m.png, what does that mean?? (le noob:o)

I noticed that the msi 7950 does not have a heatsink on one of the memory chips, should I leave it like that or should I stick a heatsink on it?

It's because the GPU Clock is what the owner has OC'd the Core or Memory too. Yours is at stock so it's showing stock values thumb.gif

Unlike previous generations where u could have 3 gtx 285s and still not max crysis. There was always a need for more power.
There just does not seem to be the software out to push this gen of cards.

Have you played Max Mayne 3? You need x-fire or SLI if you want to play it with AA maxed out at 1080 or higher. So hopelly the game developers continue to push the limits and drive the need for the next gen cards

Edit: Can't wait to see how it performs when I slap on a FC waterblock on it in a few days. thumb.gif

That high stock redface.gif My stock voltage is 993mV, no wonder that I can't overclock so well with stock voltages biggrin.gif
Can you get your memory clock higher? I got it to max 1575 without raising mem voltage smile.gif

ok

I been reading a lot of pages (around page 245 or so) people start talking about BF3 and a single 7970 with an I5 2500K and an I7 2600K with HT ON.

could someone please retest (as page 245 was quite a long time ago) and there are now almost 1400 pages and a lot of days have past sense then.


take a SIX core cpu and play BF3 MP (64 player) with HT On and track your FPS and then disable two cores (simulates the 2500K) but with no ht and then check fps again.

thanks

You have an "Enable Graphics Overdrive" check box in the right hand side. Check it. Just max out the power control slider to +20%. Push your core clocks to 1.05 Ghz (1.05 Ghz max possible) . Test for stability in BF3 or Unigine Heaven. If you see artifacts or have freezes / crashes you need to push clocks down(maybe 25 Mhz at a time and test again) I think memory can be overclocked to 1625 Mhz max (though i am not sure) up from 1250 Mhz stock speeds. Good luck. thumb.gif
Here is a thread on overclocking using third party software like MSI Afterburner which allow voltage overclocking.

I overclocked to 1hz and 1350 on my memory. ill try more later. runs stable

What are your temps on a benchmark or gpu testing program like furmark or kombustor that comes with afterburner?

And what voltage?

A little single ram heatsink that has fins would help if it fits under there. If not it is probably ok. i don't think the stock TF3 flash finless pcb heat sink helps much anyways, looks like it is just a big ineffective heat plate without any fins on it.
