7970 Asic Quality

I have a 68% and 78% 7970 atm both run about the same temps and overclock the same.

One thing the 78% one has bad coilwhine so bye bye lol.

Also i see no difference in voltages where do you see this?

Edit wtf? ive just rechecked it and now its 69.6% alls ive done is put it back in from 2 weeks ago? its gained 1.6% :D

TBH i wouldnt pay much attention to it, ive read people get better clocks with lower % and so forth.

Card 1 81.4% is the coolest by 4c

Card 2 74% is 2c warmer

Card 3 71.4% is the hottest card 2c warmer than card 2

But they all run in under 46c so it makes no ods to me :D
 
Asic numbers largely mean crap all, because its more likely they test the cards by batch then individually and if the batch is tested for say 10 samples and those samples need higher than average voltage then they'll be binned as slightly higher voltage cards... doesn't mean any of the other 90 odd gpu's on that die need higher voltage.

As a hint mine seems to run 1.12v stock under load, I can undervolt this to 0.97v and run completely stable in everything with a small overclock(about 975Mhz). What asic number do I have, don't care, won't test, means nothing. The card is fully capable of running WELL below stock voltage, the stock voltage is likely at a higher level because other cores in the batch weren't as good.... who cares.

The card you get is the card you get, asic quality is a useless measure, stock voltage isn't for certain the lowest stable voltage you actually need, its all relative.

For so many games the 7970 is so much faster than I need, Lotro/Eve, older games, plenty of other stuff, that undervolting as far as possible and saving power, lowering heat and ultimately noise is incredibly useful. Overclocking certainly makes a difference in some titles though there are very few games it can't chew through at stock... then again I don't feel the need to add levels of AA that really can't be seen unless you pause and get weird about it :p
 
My cards are not that shabby 80+% 1000core @1049v nice and stable for a modded GHZ gigabyte bios on a HIS ICEQ 7950s ;)

Which games cant it chew through and what res you game at?

Ive found my main concern to be games that are single core only to be my only problem with fps.

But the other end of the scable is my 7970 does not make games look as good as the 660 i had, im getting loads of problems with certain titles.

AMD cards render colour better than Nvidia cards, and they're working on a fix for frame time, so hang on to your 7970.

Really? Will this be in the 12.11 official?

Seriously? We all understand you're miffed, but do you have to troll in every thread on the GPU forum? This one is about the ASIC quality number and whether it practically means anything or not, it has nothing do with with AMD's drivers, your issues with your 7970, or just how much like a petulant child you can make yourself sound. Please could you lighten up a little and maybe contribute to the discussions you're joining?

Back on topic - my ASIC is 74.1%. It clocks to 1125/1575 on standard voltage. Did once try 1600 on memory but got artifacts in Just Cause 2, so popped it back down. Not tried to clock the core any higher, but I doubt I've got much left anyway. On the stock cooler it was hitting mid 80s on taxing games (and 70s on single screen taxing games). The Accelero has knocked a good 10-15C off those.
 
Cool im glad to hear of this, so this will fix all the stuttering problems and vsync issues?

To the moaning bloke above i already did post about the asic quality if you read it! Im allowed to ask questions :\ jesus so many moaning people.

You're right, I owe you an apology. Bad day and I took it out on you when it wasn't deserved.

Sorry. :(

Going to bed now, hopefully will get out of it in the right side tomorrow.
 
My current one is 68% ASIC and never went above 75 in games. The other one i had was 89% or 92% or something like that and was always running 6-7 degrees warmer, no matter what slot.

Chip you need to address the theory you had that lower asic cards run cooler as there is more gpu leakage.
 
7970 82%
clock at 1100/1600 volts 1175mv
If i up the core, I get artifacts in heaven. When gaming in ArmA2, the temps on the reference model is around 75-80c

Well I presume if there's less leakage that everything else on the board would have more voltage or current running through everything heating up the rest on it's way.

My theory was that the more volts that leak from the board the less runs through other components thereby leaving them cooler.

Could be totally off the ball tbh though.
