Yikes, my 7970 only scores 61.5 on ASIC

My Powercolor card did 1300MHz core on 1300mv.

Both my cards chug along at 1050core, 1500 memory, stock volts, 100% stable.

That's a little confusing as the lower ASIC would suggest it should handle higher voltage relatively well. The ability to run 1125MHz at stock volts is also pretty decent, so not sure what to make of that. I suppose I will have to wait and see how my card behaves, once it arrives.

Thanks.

Meaning that the lower ASIC quality chips, which are usually found on more expensive, overclocked SKUs, would probably have higher quality components compared to a higher ASIC quality chip which, as mentioned above, don't require as much voltage, etc, thus are found in cheaper SKUs that don't require as powerful components/circuitry. This means the SKU using the higher ASIC quality chip may not be able to handle higher voltage.

EDIT: Sorry, that is what you meant - misread your post. Need sleep...

I think I see what you mean, there is more at play than a single factor.

However, the card not responding to any voltage increase at all is what I was referring to as being unusual given the relatively low ASIC quality. But then, combining the, already mentioned, multifactorial nature of overclocking with the good old fashioned luck of draw argument probably puts things back into perspective.

I haven't experienced "coil whine" in a PC since before the new millennium. I never experienced whine/hiss on a GFX card either This is/was mine & family/friends experiences...

Conversely; Every piece of electronic equipment I have owned in the last 15yrs has been silent. Untill it popped... Of course

Most times I lost the PSU or some caps went up in smoke...

My VaporX 7950 is 86.3% and overrclocks like a champ beating out some OC 7970's and 680's

[Jetster]

I think my 7950 is lowest at 57.4% Do I win something?

LOL sure, until you overclock them.

If you don't like your card, how it OCs, the color of it, the smell. By all means, return it, that's what restocking fees are for.

Except we are not just saying ASIC, we are saying ASIC score or rating, and I've yet to see anyone here not know what that means, unless it's someone that's never even heard of ASIC regarding quality testing before. Kinda splitting hairs really. Sorry W1zz, not going to feel guilty for just saying ASIC score or rating like most do.

Don't care beans about the smell, unless something were to smell burnt, which it doesn't. I've always hated those pine scented car fresheners, since you seem intent on paralleling it to car maintenance terminology.

Again, not cost effective to pay return shipping AND a restocking fee just to take a chance that I'll get something with a higher ASIC, uh ASIC q-u-a-l-i-t-y rating, on the same model, or pay quite a bit more for a Vapor-X or something, that again, may or may not be binned higher leakage wise.

I'll just have to chalk this up to bad luck and be content with the fact that I only paid $330 for it. Even if only run at the stock 1000 OC, it's still a fairly good deal, until the 8870 comes out and equals it's performance for a rumored $280. Then again, even if that IS the case, I'll have had several months worth of use on this one before that happens.

i have a 68.6 and it oc higher out of 3 cards i had

they where ref. cards and even on the stock cooler at 100% fan speed i could bench it at 1300Mhz @ 1.3v in MSI AB

but thats from my experience

and the other two where higher % i think in the 80's

Probably depends a lot on fan speed, case thermal efficiency and ambient temps, but thanks for the input. Yours sounds like one of the more atypical results but I won't treat it as invalid.

It was just at around 70-75F range

But now its on a full wb and just run it @ 1174mV 1050/1500 a bios I flashed it to

Well there you go, perfect example of what I said earlier. An expensive WC setup is a risk, and won't necessarily pay off. Two 7950s, even if the cheapest available would cost probably $30 more and yield MUCH better results.

Even if just buying the WB and adding the GPU into an existing loop I tend to think would be questionable as far as cost effectiveness.

[DOM]

I had the wb in my first card which was alright but on water or stock it oc about the same wcing didn't get more its like the lotto its all luck imo to get a good ocing one

[BlackZero]

CF/SLI are not something everyone would consider risk free either, multi-gpu based systems have a host of other issues, especially the micro stutter can be unbearable for some. At least with water cooling you are guaranteed a quiet system.

Though, it's all subjective at that point as preferences and requirements can vary widely.

56.01% on my HD7950

[THE_EGG]

This is why i don't look at the ASIC of the cards I buy. I just overclock the card the old fashioned way and be happy with it.

[Techtu]

Although in all fairness I can't get my card to clock for anything, but I'm hoping that's a power issue... Soon find out when I get that other rig from MoonPig and swap the PSU's :P

I always smell my GFX cards when they come out of the box. If they do not smell like cheap beer or hookers then its a auto return and a swift call to the packing manager at newegg

I don't either. I was just curious.
