Then tell your buddy about your return and see if he can go buy the open box card(now used) at a discount.

I've actually accidentally done this at Frys.

I've bought a motherboard before which kept crashing, and I returned it. Then I figured out it was actually my RAM was incompatible and I actually wanted that motherboard model. So I went back to the shelf and picked the open-box item they had. Turns out I got the same motherboard back at a 5% markdown. Oops.

I am very jealous indeed. I do plan on getting a 7970 soon. I just decided. So if 71% asic quality is good... what is bad? How well would a 100% clock?

100% is very very very rare. Those cards are worth top dollar. I'd say average is low 70's. Theres the 7970 owners thread which lists all of the ASIC qualities people have gotten to give you an idea.

I was scowering ebay for an 80% by messaging the owners, but a majority were average. But this was a deal I couldn't turn down. (I would've if it was < 70% though. Close!)

A 100% card would have a crazy high clock with stock volts. But under water it doesn't matter much. Most chips behave the same, because the core stays <40C compared to 80C. I think asic quality makes the most difference at higher temps. (granted if you have 70C water passing over your card from a CRAZY clock, lol..)

Thanks for the response. I ended up just googling it. Since gpuz is techpowerup software I just went there. Found some threads about people posting their scores. Several had 7970's in the 90% area. When I do get a 7970, I might check this and return it if I don't like it.

How can you do that ? More specifically, how can you do that in the UK ... Grin

How I would do it is buy a 7970. Install 7970. Open gpuz. Check asic quality. If it was 70%+ I would probably just be lazy and keep it. If I got a 50% I would return it and buy another in hopes it was better. Can you not return items in the uk? Newegg in the US has great customer service. I have read, as I don't have the money, that some people will buy like 3-4 gpu's and then see which one that clocks best for them and return the rest.

That is so damn wrong.

Care to explain why?

Is there a software to determine ASIC quality?

More specifically, a LINUX software.

Why so much Windblows specific software ? MSI AB, GPU-Z, RBE ... makes me sad Cry

Make your own

It only works on some Nvidia cards and 78xx 79xx series cards

Oo)
Gpu-z is the way to go

right click on gpu-z(on the upper corner, where it says gpu-z) and select asic quality

The question is : how do you pick out the better chips before buying them ?

You can't Undecided

Unless its advertised by an end user.. Though if hes smart, he wont advertise it unless its high.

Yeah that is without warranty and used ( I call it abUSED ) so no deal there.

not jsut power. Higher asic quality = able to run higher clocks at a given voltage while at the same time using less power (less leakage). An example is a 60% ASIC quality 7970 may only be able to run 1000MHz @ 1.125v and hit 90C while an 80% quality one would be able to hit 1200MHz @ 1.125v while hitting only 75C. This example may be a bit extreme, but is pretty much the bottom line difference.

So you're talking power efficiency?

I think this guy explained it best:

Quote

It represents the arbitrary number Nvidia or ATI assign a die based on its location and performance figure they are trying to target. Just like it was said before a lower number should have higher leakage, but may also mean a closer to the edge die cut. If everything else were equal a number such as 85% should yield a balance between leakage so you can throw more voltage at it and non faulty transistors from die defects.

Lower ASIC values yield better results with water cooling or extreme cooling. Higher is better with air.

It's a sapphire board with 71.5% ASIC quality

Can you explain that? Huh

The GPU matches 71.5% of manufacturer spec. Average is 65-70%

My first card is 76.7%. Just measures the leakage. Runs on higher clocks at lower volts
