What does Asic actually mean?? GTX 680 at 100%

[Jay85]

I opened gpu-z last night and ran the asic test which gave me 100% score. Then below it had a small chart but i cant make sense of it.


Is having 100% a good or bad thing???!

Anyone able to shed some light on this and put it into laymen terms?


Thanks!

I think its supposed to represent how the card will overclock, most say its irrelevant.

GTX670 also reads out 100%.

Guess we both have good overclockers? Or really poor ones lol.

My cards a great clocker, but I'm being held back big time by Nvidia locking down the voltages

1359/7160, under air it struggles to hit 60c. No artefacts etc... just a driver crash when I take it higher.

Not seen a correlation between ASIC and overclocking. My GTX470 is a decent clocker but ASIC is something like 54% IIRC.

it was something they added because they'd worked out how to read something and weren't quite sure what to do with it... from everyone posting up what quality they got and the OC they were able to achieve there was no clear correlation between the 2

and now I guess it looks as though all 680's and 670's are just reading 100% so it's even more pointless

The next new feature is ASIC quality, designed for NVIDIA Fermi (GF10x and GF11x GPUs) and AMD Southern Islands (HD 7800 series and above), aimed at advanced users, hardware manufacturers, and the likes. We've found the ways in which AMD and NVIDIA segregate their freshly-made GPU ASICs based on the electrical leakages the chips produce (to increase yield by allotting them in different SKUs and performance bins), and we've found ways in which ASIC quality can be quantified and displayed. Find this feature in the context menu of GPU-Z. We're working on implementing this feature on older AMD Radeon GPUs.

Didn't exactly take me long...

^^ They changed the way to read data off the cards with the 6 series - you can infact destabalise the system trying to read it wrong so that might be why they all show 100%.

The numbers seem a bit meaningless but trend I've seen - which actually seems slightly different to what the GPU-Z author suggested:

Cards with low number <=60% seem to run fairly hot but overclock well, respond better to enhanced cooling than they do higher voltages.

Cards with >60% don't seem to overclock as well on stock but respond better to extra voltage and get good results when watercooled and a voltage boost.

Good info cheers Rroff

Doesn't look like all 600 series at set to 100%

This is mine.

What you said makes much more sense to me since mine is watercooled and i have upped the voltage which allowed me to bump the overclock nearly past +200mhz on the core!

Awesome explaination (thumbs up)

Checked both my 470's, one displays 69.3%, the other is at 68.3%. Both are pretty decent clockers. But hindered by stock cooling.
