MSIAfterburner.exe /rr174
 

Looks like 7990s will have higher clocks again.

AMD uses the following table to select VID depending on ASIC quality:

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

Don't forget the multigpu commands:
Quote:
If you have multiple GPUs use:

MSIAfterburner.exe /sg0 /rr174
to select and dump the first GPU
MSIAfterburner.exe /sg1 /rr174
to select and dump the second GPU and so on

*darn quote left out the leakage table.

In all reality.... You shouldn't really worry bout the VID type unless your putting them under water and going for extreme OC's.
IMO, 1050 - 1100 is really good for 24/7 on the reference cards.

Durnit. rolleyes.gif You think the various VIDs are random from vendor to vendor? I would assume ATI just fabbed the chips, assigned that register based on their testing, and shipped them to the IAB partners?

Meh, I had version : 00002ef0

Its on at 1200/1525 @ 1,2V
post #1085 of 38735
My card #1 is 2EB0 and card #2 is 3550.

Might have to play around with individual overclocks.

Both have been doing fine though 1200/1600 @ 1.2v.

Are you 100% stable? I doubt it if you have a 1175mv card in that mix.

These tables don't tell the whole story. Look at how leakage affected Intel cpus! It's the opposite of what you'd think.

Sigh, both of my cards are 1.1750V and barely can break 1100mhz individually. I haven't been able to get them over 1050mhz in cf. I'm happy with their performance but I would like to get a bit more out of em for my setup. You guys think its worth it to return em and buy 2 more if i plan on putting them under water lol? If I keep these ones I'm probably not going to put them under water because it seems pointless.

Wait. Is that voltage?

 

If not, it falls into this "up to 2F90 (up to 75% quality) - 1.1750V".
 

 

Lower is better to achieve higher clocks.

 


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
