Confused about what GTX 580 i have.

Please is someone can help with my issue.

My issue is that i ordered 2 times 3GB GTX 580s sli for my pc. But when i do a DXDIAG i only get showing a video memory of 709mb is this incorrect? or am i just not seeing what it really is.

EDIIIIIIT: When i run the normall dxdiag it shows 4059MB, but when running 64Bit it shows 709mb??

Well i know that software and your system will only ever use/see 3GB of memory from both your cards (Which in your case is the only thing that is showing correctly) but you are correct that your DXDIAG log does indeed look strange...

Yours reports:

Display Memory: 709 MB
Dedicated Memory: 3018 MB
Shared Memory: 1787 MB

Mine reports:

Display Memory: 4050 MB
Dedicated Memory: 978 MB
Shared Memory: 3071 MB

My results are the same whether i run it 32 or 64bit mode.

I am running only a single GPU with 1GB of onboard ram and less system memory than you also.

May be you should start with fully checking through your Bios. Just in case there is something in there that as been missed and may help. But personally i would say it is either down to the cards themselves or drivers. Sorry i can't be of anymore help but at least you have something to compare with. Good luck

Read these lines.

The API that DXDiag uses to approximate the system memory was not designed to handle systems in this configuration
Microsoft is working to resolve this in future release

Why do you think something is wrong? What does nvidia system info tell you in control panel about what your cards are?
