So who does bin their GPU's? - Page 4

But I think stock VID is still really just an estimation of how 'good' each chip is really going to turn out to be once it's actually put onto a card and overclocked ...

Maybe someone could ask MSIAlex on the the "Ask Me Anythign Nvidia-Related" thread he started a ways back
I can't see the VID being set during the fabrication process as all GPU and CPU have VID ranges, not just a specific single VID. They can't just "choose" a VID and throw it in there.

In reality, the VID shows absolutely nothing relevant to overclocking. A low VID means it doesn't require as much voltage for stock as others so in theory, you have more voltage headroom when overclocking.

As I have said already in this thread, binning is nothing more than sorting them based on data. Whether it be VID, clocks, etc.

Yeah, I wonder what the normal VID testing methodology is, because my MSI card had quite a low VID with stock overclocks and it wasn't anywhere close to stable.

I had to get an MSI representative to make me a new bios to override the 0.962v to 1.037 otherwise there were artifacts and errors everywhere.

But like you stated, even with such a high VID, this chip overclocks very well.

Not sure I follow your logic

Just because there's a range doesn't mean it can't be set at the time of manufacture. The fab factory can set it somewhere in that range just as plausibly as it could be done somewhere else (i.e. MSI, Asus, etc).

One thing I can tell you for certain is that the stock VID doesn't appear to be set in the bios. You can go through every bios they have in the bios DB at TPU and flash your card w/any of them (all the different brands) and your stock VID isn't going to change ... I know this because I've had my cards on bioses from like 8 different manufacturers.

This is not to say that a different 'stock VID' cannot be forced through the bios, because it can. But if you look at the voltage table in NiBiTor for any bios for your card ... it will look exactly the same. Nowhere in there are you going to see your stock VID spelled out.

This collection of observations makes it appear to me that the stock VID is built into the chip itself.

So if it's not built into the chip itself, and it's not in the BIOS by default ... where it stored, and who set it?

The post you quoted actually brings up another valid point, if there were no binning process, why do VIDs differ? How would we know that one card needs more voltage than another card without testing it? It'd be stupid not to bin if you already had to test them.
How was'nt I participating in my thread?
Looks like you don't know anything anyway so go try tell people what to do in another thread.
