ASIC quality ratings?

post #1 of 7
Thread Starter 
Checked my asic on my 7990 today and it's 64.8%

Does a higher ASIC = better OC potential?

Let's discuss this "myth"

Here is a very interesting statement I found elsewhere that counters this argument:

"Higher Asic does not = higher quality. It just means it requires less volts for a similar core clock. This is only a good thing up to a point as high asic cards tend to not like high volts. So a low asic card of around 60% may take 1.3v while a high asic card of 90% will hard lock at 1.2v for example. All of the 7970 Matrix Platinum editions are low asic cards so they can reach higher stable OC at higher volts.

If you want the highest potential overclock a low asic card will usually be better. If you want lower power usage and are happy with a moderate overclock then high asic is better."

Thoughts?

ASIC does not matter really, the quote you have there is as good explanation as any.

I have seen low ASIC quality overclock way higher and at lower volt, than high ones. And the other way around.
It's just the silicon lottery, and you don't know how good the card overclock's until you have it in your hands.

So in short, a low ASIC card can be just as good as a high one.

The Asic quality on my card is low 74% but I was able to overclock to 1205/5800 at 1.2 Volts, running perfectly stable, temps never reach 70C through gaming or benchmarks.

My 7950 is 58.4%. It already coil whines like crazy on stock clocks, I dare not add voltage.

Coil whine does not mean something is wrong....

Actually, you might be able to interrupt the harmonics by overclocking it.

my 690 has an asic of 69% but it Oc's like a beast. I wouldn't put too much stock in the "higher asic=better oc" myth.

Thanks for your posts everyone smile.gif

So, can anyone verify that a lower asic rating (on average) is more suitable for higher voltages?

The statement I provided mentions that asus matrix cards tend to come with lower asic ratings; if this was true, and given the fact that the matrix cards usually clock higher than other cards: Could there be some truth to this?

I realize that the asus matrix cards come with different components and better cooling but still... If asus are picking lower asic chips specifically for these cards I would have to say that it's a very possible conclusion.
