ASIC Quality - What is it? Compare?

[blastingcap]

There is a known bug where GPU-Z's "ASIC score" is incompatible with all NVIDIA GPUs and older AMD GPUs. That's why there are people out there with "104% ASIC quality" GPUs which is of course ridiculous. Also, Tempered81 did a good job of explaining why the entire chain matters. Obviously if your GPU is the weakest link then it's the weakest link, but even if you had a perfectly formed GPU, the best of its kind, if the heat spreader is not level or the TIM was put on badly or the fans aren't good or the PCB circuitry, VRMs, chokes, capacitors, etc. have problems, then it doesn't matter how good your GPU is, because it won't be the weakest link.

Or to put it another way: if you have a great GPU and a terrible CPU, you are bottlenecked right? Well if you have a great GPU sample but any part of the rest of the video card isn't as good, then that part is bottlenecking your GPU.

note ; I didnt think the forum needed another post titled ASIC Quality, so I resurrectedly necro'd this post. <3 zombies
My Powercolor 7970 2DHV3 has a ASIC quality of 63.1%, and I've been reading about this ASIC quality riff raff here and there on the web....


I must say I think im more confused than ever. What could be limiting factors on a gpu core over clock on a 7970? I'm using MSI AB , and current OC is 1100/1500 1.2v core untouched memory voltage. Power Limit is at 0%

Is 1.3v okay , long as temps of gpu core and vrm's stay under control? I have read everywhere online that you should just slide the Power Limit all the way to +20% but that doesn't make sense in reguards to what I have been reading about ASIC quality and leakage. I don't think I quite understand how leakage / asic quality / voltage / temperatures are all contributing factors to my overclock.

Stuff's giving me a headache, and im pretty sure I should be able to OC my card pretty high considering temps and everything I've witnessed thus far, but I'd prefer know a little more about this stuff before trying to OC any higher, cuz im tired of unknown reasons for instability.

Anyone ?

Set the power limit at +20%. It doesn't actually increase voltage or anything. 1.3v is pushing the card to the limit on stock cooling. There hasn't been studies that I've ever seen for asic% in regards to performance, in any way.

See what you can get @ 1.2v with the power at +20% Leave memory stock and see what you can get out of the core only. You can increase voltage to see how much more you can get. Often the extra clock speed isn't worth the additional heat. Once you've found your max stable O/C, then start increasing memory clocks.

My ASIC quality is 57.6%, other forums say hardly anyone gets over 60% on cards in the last 5-6 months. I don't give it much thought unless I read about it. I have my overclock stable, so that's what counts for me.

Yeah nfi how reliable it is i have 2 680s one is 79% the other is 61% yet both are stable +200 +220 clk/mem for me in SLI so im fine with that.

 

[willomz]

I've got 88.5% on my 660.

 

[AdamK47]

71.4%
65.0%
73.9%

 

[Zanovar]

just checked 81.2%.im sure it was 100% when i bought the card lol.

 

[BallaTheFeared]

lol, tough luck... That's 19% you'll never get back >.<

 

[Zanovar]

lol, tough luck... That's 19% you'll never get back >.<

The card I currently have :

GTX Titan : 74.2% (1176mhz stable at 1.2v)
GTX 680 : 91.2% (1280mhz stable at 1.2v)
GTX 660 : 71.1% (never tried overclocking)

I'm not sure why lower ASIC quality is better for water cooling. My thought is that you'd want as high and ASIC as possible. If high ASIC means less voltage required, why does it matter if on water or air?
