Is my 8800GTS 320mb or 640mb?

I purchased my 8800GTS graphics card believing it to be 320mb, evrything on the box and description said 320mb, but, when I run diagnostic programmes on my comp its reported at 640mb! Have they put the wrong card in the wrong box or am I reading things wrong? River Tuner reports 320-bit G80 (A2,96sp) with 640mb DDR3. I have pasted results from Riva Tuner below, please help.

Ok will do

jipped? how so?

Lucky chap!

Still, 640 cards aren't really that much better than 320 cards - shame they didn't give you a GTX instead

Its BFG 8800GTS bought from PC World, came in all BFG packing even had the BFG T shirt in the box, BUT, it also comes with a programme called XpertVision which is a small overclocking thing that allows you to increase the mhz in both cores. When I contacted BFG about this they said I had not bought a BFG card but I had bought an XpertVision card. I visited their website and my 8800GTS dont look anything like theirs although they only seem to seel the 640mb card. I am as confused as hell!!

£185 web only price, should have been £225

Have done that and it states that approx total memory 640.0MB

well then its 640mb, thats worth prob 60$ more than 320mb. Never heard of xpertvision though. Looks like sketchy, it seems you might have gotten a returned card that was repackaged into a BFG box and sold.??

My friend has got a BFG 8800GTS card and we put it in my comp to run in SLI mode but we couldnt get it to work, this may explain why

Yes it looks exactly like my friends card came with the T shirt and everything

Open EVEREST ULTIMATE EDITION , ---> DISPLAY ----> GPU , and here u will see the specs

an appropriate comment given your "Here endeth the warranty, and pass that fire extin(guisher I assume)" part next to ur name

The trouble is I want to SLI the buggers and I dont know what other card to pair my existing one up with!!

unless they then claim the warranty is invalid

I haven't looked at the legality, it just seemed the kind of thing that might happen in a worst case scenario

I have been in touch with BFG and they want the serial number off the back of the card so will take the thing out and send it to them and see what they say, what a blooming palava

so lucky u , u get a 640 for a very good price
