What are your settings so far? Also what driver are you using? And what version of AB?
Do you have GPUZ on your system? If not...go get it.
Open GPUZ and click on the Sensors Tab

Then where GPU Core Clock is listed, click on the little black arrow pointing down and select "Show Highest Reading"

What is your max clock when benching?

I started off with +100 mV, 200% power limit and +100 MHz core clock.

Like I said, starting Heaven the first time (when you press run), resulted in a crash. Starting it immediately afterwards, I can run the benchmark until the end. First attempt got me 129.0 FPS average and a score of 3249 (default settings).

My driver version is 306.97, 2.30 for Afterburner.

Max core clock: 1293.4 MHz.

Soyou press run to start Heaven, it crashes, and then you have to press run a second time and it will complete? Or it will crash and then auto restart itself? Does this happen with any other benchmarks, like 3Dmark11?

Yes, exactly. It does not restart itself. I have to do it manually.

Has not happened to me yet AFAIK. But tbh, I have run 3DMark11 only once.

I seem to be able to clock higher stably on drivers 306.97 or earlier., benching on the later drivers don't work as well, for me at least don't know about anyone else
post #4456 of 7827
Same for me, I went back to 306.97 last night.

Yesterday i changed the LN2 BIOS of my card (80.04.47.00.19) with 80.04.28.00.3A and began new overclock session smile.gif In Unigine Heaven 3 i reached stable core of 1385Mhz (without memory overclock) with Core Clock + 93 and AUX Clock + 40. Without core clock and rising voltages the memory goes to 4000Mhz (8000) , but when tryed simultaneous core and memory clock the stable clocks were 1359/7600 :


3DMark11

Yesterday i asked MSI support why there is no difference in overclocking between the default BIOS (80.04.47.00.18) and the LN2 BIOS (80.04.47.00.19) and they answered me:
"Regarding your concern,it's normal that the two bios are same in core clock,but the LN2 bios has extended the limitation of OCP and add the function of APS."
What does OCP and ASP means ?

Very Nice there, never tried the aux yet but would any of use recommend that high for 24/7 OC? i'm wanting more than 1333.

I don't know, but the voltages in 3DMark11 max goes to 1.365V (core clock is + 81), i believe if core clock is at max (+93) it will go to 1.375V max in 3DMark11. I am measuring with digital multimeter, because the software shows max 1.275V. I am not sure is 1.375V still save voltage for the core? I found that with 3A BIOS 1300Mhz is easy possible without rising any voltages. I have found what OCP and ASP means:
OCP = Over current protection
ASP = APS (Active Phase Switching) APS is Active Phase Switching is complete function to Control Power Demand , helps to stabilize the voltages

Still tinkering,
+100mv(93) , power limit 300, aux +50, core +160, mem +405
cpu @ 4.8 1.355v
unlocked 3a bios, with 310.70 beta drivers
Afterburner 2.2.3 no voltage hack




With voltage hack i think i can take these to a stable 1400 with about +25-30mv.
