What is a binned chip?

'binning' is the process of testing chips for certain criteria and marking them for a particular group. In this case a chip scores a better mark, so it goes in a higher 'bin', or one fails a higher test, but passes a lower test, so goes into a middle 'bin' etc.

So in this case, he is inferring that the chip was a higher binned model, i.e. it passed the higher tests so more likely to overclock better etc.

I wonder if EVGA, MSI etc bin on ASIC value or maybe that would be too simplistic :confused:

I've never looked that much into it. drunkenmaster takes a keen interest in this side of things, so he might know more. I really wouldn't be surprised if the chips were sold by Nvidia in binned batches at different prices with them doing the binning as such, but as to how they bin.... anyone?

Seems plausible.

Cheers. Are you overclocking? if so what can she do.

Seems to be good for around +200 on core and +160 on mem, only tried a few laps of the Tomb Raider bench though, which isn't the most demanding.

I'm not really much of an enthusiast when it comes to overclocking.

Good find

So in essence, there is some value in buying the classified & Lightening cards.
Over spec'd PCB's & components allied to potentially tier 1 chips.

My only real beef with the Classi is that the memory manufacturer is a lottery.
I have a feeling I have Elpida on mine but short of taking the cooler off, I will probably never know.

Truth is, on every level, it doesn't really matter but when buying the best, you generally expect the best

Take the cooler off and have a look. I wouldn't be pleased getting Elpida on a Classy but would accept SK Hynix. It seems to clock just as well as Samsung.

I'm sure that EVGA guy on here said all Classifieds are samsung memory.

I'm a bit loathed to do that as I don't intend water cooling.
If it were simply a case of lifting 4 screws, I might have a go.

I know it shouldn't, but it will bug me

You are correct.

I think he stated when pushed that all Classified's would be produced using Samsung memory.

Checked the EVGA forum but they have no idea either.

I don't think that the fire at the Samsung plant helped matters!!

Really wish that there was a piece of software that would fully analyses the components on a graphics card :mad:

Nice, can you confirm if it's full GK110 i.e 2880 cores?

Appears to be confirmed now.

My stock has shipped, so OcUK will have plenty for launch.

Just reference at launch or do you have some customs on the way?

Please keep in mind he is talking about the Classified card.
Customer Reporting they reach under water with the modded BIOS you can get in our Forums 1.4+ close to 1.5
All actually available Classified cards have Samsung RAM

Found quote from EVGA rep.

I'm not convinced though

Adam123 · 31 Oct 2013 at 23:32

4Gb as standard would have been nice, not just 3gb

Supposedly a high ASIC can lead to better overclocking results.

Hey Raven

Just bought an EVGA 780 Classified.

Has an ASIC value of 86.2

Where are you all getting this information on ASIC values and why are you so concerned with it?

I did a lot of research on this about a year ago and came to the conclusion that it wasn't something to worry about. That the method of calculating the ASIC value during the binning process is not only based on the leakage value of the chip but several other factors as well, like the location on the wafer, ie if its closer to the edge or further in. All these combine to make a number so arbitrary that it's meaningless.

And if you look on forums around the internet I think you will find that the ASIC value doesn't seem to have any correlation to how good a card is at overclocking or chip quality. Even GPU-Z seems to change it's mind about the values between each version of it's software.

I have seen classified's with ASIC ratings around 70% and less. Hell I have seen Titan's around 65% ASIC quality.

So to sum up, I don't know exactly what ASIC means in relation to GPU's, but I fairly certain that it means nothing to how good your GPU will overclock or to the quality of your GPU in general.

You are probably correct

From my own experience over various card generations, my 780 Classified ASIC reading is by far the highest I have encountered.

Now this may be total coincidence, but this is the first time I have purchased a top end, i.e non reference card.

Whilst I tend to agree, based upon the little research I have carried out, that the ASIC value is meaningless, there has to be some science behind it.

Whether a "binned" chip automatically guarantees a high ASIC I have no idea.

Ironically, a lower ASIC value is supposedly better for water/LN2 which is what I would imagine a large proportion of the "real overclockers" are using to cool their cards
