I am wanting to sell my current card (GTS 640) for around 200 or more if I can get rid of it for that much. Am aming to sell it to a friend of mine but her currently has a BFG 320. so Is it possible if he can run both since they are the same card just diffrent brand and lock speeds, as long as he underclocks the 640 first? or am I missing somthing.
Able to SLI 8800 320 and 640?

No, the cards have to have a matching bios.
In some cases even 2 of the same card that are different brands wont work.
There may be a way to mod the cards bios to match that of a 320, but not only would i not try it, downclock the 640 to 320 speeds, and disable the extra memory controllers.

Acanthus are you sure about the matching BIOS? I know that was a factor when SLI first came out (E.G. NV4x) but newer drivers enabled cards from different manufacturers and different BIOS's, albeit the same Core and Mem.???
OP: no I don't believe you can SLI a 640 and a 320. You need 320x320 or 640x640 AFAIK. I don't think Bios matters anymore since late NV40.
its amazing how many people reply having absolutely no experience concerning the issue, and still feel like they need to open their mouth.
it can be done, and its very easy too. it does not involve modifying anything in the bios (like some people said :roll
. all you have to do is use coolbits.
Here are some useful links:

And this is how you enable coolbits:

isnt it better to stay quiet and be thought a fool, then to speak and remove all doubt? you people should do your homework before you reply, and if you dont feel like helping out, then at least dont post misleading replies.

I love the personal insults and mudflinging there jag.
I have *NEVER* heard of someone successfully doing this.
Can you show me one person doing this with a GTS320 and 640?
Lets hear you back up your claims after opening your fat mouth, you immature insulting little sh!t.
The 1st sentence of your referenced paragraph.
"While it is not recommended"

It is supposed to work with mix and matched bioses as long as the cards are the same clock, but it doesnt always.
amazingly, I am still the only one that helped the op in this thread. I never attacked you personally acanthus, as a matter of fact I never specifically mentioned your name in my reply. my reply was a general statement that all the replies in the thread were wrong and/or misleading. but since you put it this way, congratulations keep going off topic. i guess if we were all like you, we would all have 13k posts, since most of those are garbage. 3/3 of your posts in this thread do not help the op whatsoever. all of my measily 900 posts have been helpful as far as I can remember (except for posts wasted on akshayt, but come on, I had to pitch in there). so before you specifically go calling me a little sh!t, if I were you I'd choose my words more carefully.
edit,
just to add to the conversation, the bios and the clock of the cards DO NOT have to be the same (and so doesn't the memory size). Both the bios and the clocks of the cards can be different, and the cards will work just fine. nvidia does not reccommend running different memory sizes (you dont have to be engineer to understand why thats bad. you will basically be limiting your frame buffer to the smallest memory amount, in this case 320MB. basically, the only thing that needs to be the same for SLI to work is the GPU. all other aspects of the cards are automatically downscaled to the lowest performing card (clocks and memory wise).
Do you even have SLI acanthus?

While you have a point Jag the Nvidia site claims it works, the Geforce 8 is a completely different beast and different drivers so it may not work at all
you know what vinny, like I tell everyone else, YMMV. point is that theoretically it can be done. whether or not nvidia developers want to make decent working drivers, and fix the innumerable bugs ntune has, does not depend on me. unfortunately with new technology come new problems.

Well Jag, we might have missed the SLI info, but that doesn't excuse you being a rude idiot. These internet tough guys deserve a real beating.
im not trying to be an internet tough guy, i just get very pissed off when i see a whole bunch of replies and they are all wrong, and then the op even says OK thanks. so he even believed you, and you have no shame in the fact that you have given him wrong information.

SLI has evolved quite a few times since in came out. At first, there was the need for identical cards right down to the BIOS. Then nvidia made it possible for cards from different manufacturers to work together. No flashing necessary. Which is what I told the OP. You said yourself that nvidia does NOT Recommend using two cards with different frame buffer sizes. So why should I? Can it be done? Anything can be done eventually, except maybe getting you some manners. Work on that. Then look back on this thread and see who should feel any "shame". -Thanks
Jag87 you need to cool off. I'd even go so far as to say you need a vacation for this thread.
Keys was just trying to be helpful, and really he didn't say anything untruthful.

So why are you reccomending something shaky to someone when they ask a very specific question?
The answer is: because for some reason you want to think youre outsmarting people.
actually, someone asked a very specific question and I gave a very specific answer, while the rest of you just said it was not possible without being bothered to find out if it was possible or not.
thats what bothers me, but heck fine I apologize if I was rude. I just hope you guys understand why I got ticked off, thats all. Sorry keys, sorry acanthus.
cheers :beer:

Sorry to burst your little bubble JAG but you do need the same card and manufacturer. I have been testing this ever since G80 came out. The card has to be the exact same model from the exact same manufacturer. I have tried tons of 8800gtx's with different manufacturers and they dont work at all. as soon as i get into windows the screen gets stretched and overlapped. Now when I replace the 2nd card with the corresponding vendor of the first card. The machine runs flawlessly. On the contrair to what you said. You need to do your homework and review what you said yourself. You were completely off with your posts. A PNY 8800gts 320 will not work with an EVGA 8800gts 320. They both have to be the same model. 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.
I would like to know as I think Nvidias information could be old on their site.
I recommend that the OP emails Nvidia to find out if it can be done. (Unless he gets a standard response from their FAQ).

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...
my eyes must be deceiving me then, cause this sure looks like 2 different cards http://theinquirer.net/images/articles/g80sli.jpg

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:
here ill throw in another picture for you oblivion,

i believe those are 2 8600GT cards, one evga card and one xfx. Guess what, sli works.
