Did you adjust Memory Voltage? Right now i am stable 1165Mhz @ 1.175v. Memory @ 1575. Should i bother to OC it more or the gain is minimal?

To those saying OC is temp dependent, I had the unfortunate situation yesterday whereby AB 'forgot' to apply my fan curve, so I was happily playing Mass Effect 3 (multiplayer) with 16xEQ AA on, pushing both 7970s to 70ish%, until I ended the round and noticed that both cards were @ 93C with 23% fan speed eek.gif

No artifacts whatsoever.

I blasted them with 100% fan speed ASAP to get them down biggrin.gif hate seeing temps that high, even if very briefly.

what are you using to get your AA that high?

I'd like to keep the clocks 1Ghz core and 1400 Memory and thus, I'd really like to know about yours. Do I have to worry about ULPS? Trixx kept spamming "You need to disable ULPS" but it couldn't give me option how to do it. Afterburner once, I don't know why, it kept the 1Ghz, but lowered back to default the voltage and suddenly got a crash after a tank was firing on me ( intense scene ).
Any advices or about your experiences would be much appreciated!
Drivers: 8.95.5 and just for the record, I haven't experienced a signle problem while running at default clocks.

Yo dude smile.gif

I have ASIC 74 and 78, my cards are 880 stock and run at max 990mv. Overclocked i run both cards a 1100/1700mhz at 1130-1150mv...

I have had every possible problem, you would seriously not believe me..lol. But suddenly everything worked. Almost out of nowhere, BUT i THINK many off my problems came with using TRIXX. So with some work i now only use afterburner, i'm never opening trixx or ccc. I also had some sudden volt spikes using trixx which i only now see if i run at "extreme" clocks...

It only happens when the card is close to it limit and has low ASIC Quality.

Here are my logs if anyone is interested with a similar setup.
I've also found my spot on the CPU 4.8@1.45 with auto offset. Cards are 7950 CFX.
The bench I was using was 3Dmark 11, Graphic Test 1 @ [P] mode. Temps are max temps reached during bench. Driver: 8.95.5-120224a-134185E-ATI
Test#, Core Clock, Memory Clock, Voltage, AVG FPS, Full load Temp
Test #1 - 800/1250/1.093 = 56.41@38C
Test #2 - 825/1275/1.093 = 57.59@38C
Test #3 - 850/1300/1.093 = 59.21@39C
Test #4 - 875/1325/1.093 = 61.02@38C
Test #5 - 900/1350/1.093 = 62.55@40C
Test #6 - 925/1375/1.093 = 64.30@40C
Test #7 - 950/1400/1.093 = 65.33@40C
Test #8 - 975/1425/1.093 = 66.92@41C
Test #9 - 1000/1450/1.093 = 68.61@40C
Test #10 - 1025/1475/1.093 = 70.06@41C
Test #11 - 1050/1500/1.093 = Lock
Test #11b - 1050/1500/1.125 = 71.50@41C
Test #12 - 1075/1525/1.125 = Lock
Test #12b - 1075/1500/1.125 = Lock
Test #12c - 1075/1500/1.150 = 72.41@41C
Test #13 - 1100/1500/1.206 = Lock
Test #13b - 1100/1500/1.206 = 73.19@42C
Test #14 - 1125/1500/1.206 = 73.55@42C
Test #15 - 1150/1500/1.206 = 73.63@42C
Test #16 - 1175/1525/1.206 = 73.85@43C
Test #16 - 1200/1550/1.206 = Lock
Sweet Spot = 12C, 1075/1500/1.174
- I bumped up the volts because temps aren't being affected by it and gives the card a little more head room if it needs it. I can't complain, 800/1250 stock, that's a nice increase.
