I have two cards GTX 690 (dual core). I did the Sli successfully. Nvidia control panel acknowledges the two cards as quad Sli.
However, the problem is that Windows 7 64-bit Ultimate is showing me the graph memory size as 4 GB while it is supposed to be 8 GB because of the Sli. Also the benchmark from all software is giving me a very low score compared to some other guy's benchmark on YouTube.
It gives me a big headache. Does anyone know why this is happening? If so, how can I get Windows 7 to recognize all 8 GB of memory?
Thanks for your help in advance.
My computer specifications:
(Processor: Intel Core i7-3930k @3.2GHz(12CPUs))---
(Memory: 65536 MB Ram 1866 MHz)--
(OS: Windows 7 Ultimate 64-bit)--
(OCZ 240GB as SSD PCIe drive for booting and storage disk)--
(DirextX version: DirectX 11)--
(VGA Card: 2 X EVGA GTX 690 Dual GPU. Each GPU is 2 GB, so total memory should be 8 GB.)--
(MotherBoard: ASUS Rampage IV Extreme)--
Others with lesser specifications get a 2500 score in heaven benchmark while I get 1501 as if it is one card.
