I agree with what Acanthus said. He was even more correct on his posts than you were with the whole thread. choose your replies and words more carefully and you will become a much smarter, logical person.

my eyes must be deceiving me then, cause this sure looks like 2 different cards http://theinquirer.net/images/articles/g80sli.jpg
from this article http://theinquirer.net/default.aspx?article=35604

and I can find you tons of other pictures, thats just the first one that popped into my head. i remember seeing that picture on the inquirer.


and lopri, its always been a dream of mine to end up in someone's sig. thank you! :heart:

Those are not different cards.

They have identical bioses (other than manufacturer info embedded to ID the card).

oh rly? I believe not only the manufacturer is different (which already disproves oblivion121) but the clock speeds are ALSO very different. read carefully acanthus.

peace ;)

That's funny, because when the 8800 came out, every single board, regardless of "vendor/manufacturer" was actually made by Asus... hence people running SLI with an EVGA and XFX board, or EVGA and BFG, or BFG and Asus... etc... etc... etc...

Which means all of those cards would be identical with an identical bios.

:confused:

peace ;)

Default clockspeeds are about 3 bytes of code in a bios.

If the bios code is the same, then it will work.

If the code is drastically different, it will not work.

I still contend that you find me the situation in the OP working. Beacause you made a bold statement with no backing at all, and are citing unrelated evidence about mixing OEMs, not framebuffer sizes and different bioses.

oh yes I agree with you on the frame buffer size, but the bios has absolutely nothing to do with it. for the bios to be DRASTICALLY different, the cards must have a different GPU. otherwise all the bioses are essentially the same, all that changes is the vendor ID, the core/mem clocks, and on the OC cards the fan speeds. thats it.

the frame buffer size thing can be worked around as I explained earlier. and it can be done. I just dont understand why one would castrate their 640M card like that but hey, its your money...

So you would assert that you can use NVflash to flash a GTS640 to a GTS320 with no ill effects...

Futhermore that you could flast any GTS with another BIOS from another GTS with no ill effects...

That all of these are identical code except for OEM code, clockspeed, and framebuffer sizes.

in the order that your wrote:

probably yes, the card would only address half of the memory chips on the board. now, if the memory ICs are actually the same number but smaller (eg 32mb vs 64mb ICs) it definetely wont work.

yes, for sure. Ive done this before with a GTX card.

Are GTXs under "nvidia lockdown" though and being produced by one OEM?

Nvidia has been doing this since the FX5800s for their flagship card.

This probably isnt the case with GTS's.

There are 12 chips on both the 320MB and 640MB.

The densities are different.

you can do the flashing with both GTX and GTS cards. they are all the same. heck if you peel off the sticker from the heatsink they all have the same nvidia sticker underneath. as far as the 320 vs 640 discussion, if the ICs have different memory density than it cannot be done. My educated guess is flashing a 640 card to 320 bios will brick your card.

but SLI can be done ;) you just need coolbits and a working ntune :roll:
