Sandy Bridge onboard graphics BIOS question (Gigabyte H67A-UD3H-B3)

post #1 of 3
Thread Starter 
For "On-Chip Frame Buffer Size" it's currently set to 64MB+2MB for GTT, is there benefit to increasing the buffer size? say 128MB or 256MB?

I'm planning on running dual monitors using onboard video.

*edit* - Just searched Bing and Google and there seems to be no relevant answer to what is On-Chip Frame Buffer Size. The name sounds like how much memory is reserved for graphics. Since I have 4GB of RAM setting it to it's maximum, 480MB shouldn't be a problem, but I want to confirm that is the true function before doing anything.

*edit 2* - My WEI score was 3.7 using a Sapphire 5450 512MB DDR2, it jumped to 5.2 using Sandy Bridge's integrated graphics, sweet!

I haven't seen any indication that you can run 2x monitors with the on cpu gfx.

Sandy Bridge supports dual monitors.

The onboard video is Unified Memory Architecture (UMA) meaning the memory size I select in the BIOS determines the maximum amount of memory allocated to graphics. Once allocated it can only be used as graphics memory and no longer accessible to the operating system or applications.
