Ken is that why AB was giving me voltage reading that appeared too low after I hit reset? The Default is 1175 in Trixx for me, and it was going down to 1049 after hitting reset in AB.
 

 


Actually all hardware monitorings are using default hardcoded voltage 1.175V. Hitting "reset" actually set it to read 1.175V rather than actual voltage based on ASIC quality leakage level.

 

To identify the ASIC VID;

 

Single GPU switch;

MSIAfterburner.exe /rr174

 

Multi-GPU switch;

MSIAfterburner.exe /sg0 /rr174 ----> First GPU
MSIAfterburner.exe /sg1 /rr174 ----> Second GPU

MSIAfterburner.exe /sg2 /rr174 ----> Third GPU

 

Up to 2F90 (up to 75% quality) - 1.1750V
Up to 34D0 (up to 80% quality) - 1.1125V
Up to 3820 (up to 85% quality) - 1.0500V
Up to 3A90 (up to 90% quality) - 1.0250V

 

 

Other hidden switches for advance users;

 

MSIAfterburner.exe -xcl to Extend Clock Limits of AMD Overdrive - Reboot PC.
MSIAfterburner.exe -rcl to Restore Clock Limits of AMD Overdrive - Reboot PC.

 

To acces voltage tweak, enable "Unofficial Overclocking".

 Mine drop to 949 is that right?

 

That's UVD, not in 3D full clocks.

ok, but is the Crysis guru3d 1.05 ok for stability checking or should I run something else.

Also looks like I'm about to skip overclocking, too complicated, all this asic and voltage leakage has me worried lol.

when I put //rr174 in afterburner I get this and I know in gpu-z asic is 77.70%.

Not to imply that you are, Balsagna.
Anyway, I personally couldn't push my card past 1070 MHz core no matter the voltage.

I hear what you're saying. HD7970 is a funny one to overclock though. Mine will run with no errors at 1240/1700 but will error at 1250 on OCCT. However, it has never crashed or had artifactS in any games at 1250, but I put to 1240 to be on the safe side.
Now I have been using Crysis 2 bench to test also and it failed @ 1280 core so I assumed it was too high, even though all games and benches no crashes or artifacts, but it will error in OCCT. Then I noticed it would crash also at my safe clocks, when previously stable, crysis 2 bench that is. Then I tried at stock clocks and it crashed also lol. So I will reinstall that app at some stage.

I can bench with 1300 on the core with only a couple of crashes, (weeks of benchmarks at this stage)but I did have the memory real high also so not sure which caused.

I am starting to think, the extreme overclocks, 1280/1300 are perhaps within reach and it is drivers which are causing issues. Some things run stable, some don't. Which is to be expected I guess with a new card released. Finding absolute limit on my card has been illusive. What is ok in one bench is not in another, card cannot handle or is a driver issue? Hard to say.

I've got 3 74% cards, all do 1235-ish and 1700 memory.

I'm 70.5% and running 1240/1700 stable in everything. Benched the hell out of it and been running those clocks for a week or so no crashes.

I'm kind of out of the loop about ASIC quality and things like that. What do I need to do to get that sort of information? Right now, all I did was flash both of my cards to the ATI Unlocked bios and used either MSI or Trixx to do the overclocking and used CCC to get the +20% (did it through AB now since they allow it)

What does ASIC tell you and what information can you use from it? Thanks!

Click the green button in gpu-z and then click Read Asic quality. It tells you what default voltage your card runs at. Outside of that, there is a lot of speculation on whether it means anything or not. My 74% asic quality chip does 1300/1750 on water.
