You guys should see my ITX case lolz
2 140MM intakes and 2 120mm exhausts!! biggrin.gif
just ran heaven 3.0 and max temps were 69* C on stock volts @ 1065Mhz...
but i got a lower FPS scor then when I was on the 12.8 drivers.....im on the 12.7 betas right now and BF3 has crap FPS frown.gif
also what gives!!!! Just idling and moving my mouse around the desktop!

you have not maxed out power option to +20%. thats the first thing to do. without that your card is power constrained. Push that slider to +20% . and tell if your perf is better.

I recently bought a HIS IceQ 7950 http://www.newegg.com/Product/Product.aspx?Item=N82E16814161407 and my computer freezes when I play Diablo 3 on low settings in both CCC and the in game settings. I'm using MSI AB and I'm not OCing my voltage, but I upped the power limit to +10%, the Core Clock to 950 MHz, the memory clock is the stock 1250 MHz, and the fan is running at 80%. My idle temp is 31C, and Load while playing Diablo and Heaven 3.0 is 55C. Playing Diablo/Heaven 3.0 is 99% GPU usage, maximum memory usage was 1221 out of the total 3GB. Diablo is around 40 FPS with those low settings, and Heaven 3.0 was an average FPS of 137.7, with a Min FPS of 43.5, and a max FPS of 231.3 granted this is with basically everything turned off/lowest levels they can go. Using CCC version 12.8, drivers are completely up to date, CPU is an AMD Phenom II X4 955 black edition at 3.6 Ghz, and my main board doesn't support PCIe 3.0 only 2.0 but from what I've read that isn't anything that would effect this and won't really be used for awhile, 8GB DDR3 ram at 1600, and I have a 750 watt power supply which should also be more than enough for this build. I searched this forum for some advice and downloaded Heaven 3.0 to use that to benchmark numbers. I don't think my CPU is bottle necking my GPU but it could be... Any suggestions on what to test next/where to go from here?

With sapphire trixx get that bad ass chip to 1.15 Ghz with a slight voltage increase. just build a custom fan profile in sapphire trixx to keep the core temps at 70c . thumb.gif

Downloaded trixx now, I don't see a voltage increase thing though. Only that basic power stuff which is at 20%

there is a scroller on the side in overclocking in sapphire trixx. move it down. you will see VDDC. thats core voltage. first see whats your stock voltage. try to run overclocks with stock voltage. start with 1050 Mhz and stock. if things are stable, try 1100 Mhz. if unstable increase voltage by 0.05v. so if stock is 1100 mv push to 1150 mv.

So can anyone achieve 1050mhz of OC on stock voltage?
post #15338 of 38704
Voltage is at 975

I did try 1050Mhz last night and noticed some line shooting across the screen randomly so put it back down to 1Ghz.

I just ran Heaven 3 basic (no tessellation, want me to enable it?)

I took a screenshot of results but the screenshot ended up blank and I can't find where the results saved, I'll run it again now but the average FPS was over 100

LOL don't even ask whats up with the "GPU model".

How is this score? Good, bad, average?

run Heaven with tesselation extreme, 8x AA, 16X AF , everything else maxed out. lets see the score. also for voltage increase try 1.1v and 1150 Mhz.. thats a good balance of perf, power and fan noise. you could set fan speed manually to 70% . later you can create a custom fan profile in sapphire trixx. monitor temps in HWinfo32 . it allows logging temps to a file . so start logging and then run heaven 3.0 . GPU temps should stay below 75c and VRM temps below 95c for safe operation.
