Hi I have an MSI X58 Pro-E, 6gb Corsair Dominator 1866mhz triple-channle memory and an ATI X1300/1550. The Graphics Card is obviously crap but I'm saving up for the minute. Without me doing anything it adjusted the shared gfx to 2811mb, and I can't find an option to alter this to a lower amount, as I'm only going to be playing basic games on a card like this. How do I change it?
Thanks!

I'm not too smart but the shared memory is used with onboard gpu or chipset and can be adjusted... with a ded.card I don't know why it needs to share the system memory

I think it's doing it as it has so little dedicated

This is normal.

The Display driver can shift some of the PC's memory to the kernel's non-paged pool and use it as additional video memory. It will only do this if it needs to though to prevent crashing and other nasty things.
Notice that the "Dedicated system memory" is zero. The "Shared System Memory" will always be between 40% and 50% of the total installed capacity.

EDIT: The actual formula used to calculate this value is:
((SystemMemory - 512) /2) - Dedicated System Memory

So in your case, (2811 * 2) + 512 = 6134 which is what I bet corresponds to 6GiB of installed capacity less hardware reserve allocated by the firmware

I know that you're able to do this from a uefi bios and change it though, as 2.8 gigs seems very excessive. If I can't change it though thanks for explaining it so well!

You can adjust the "Dedicated System Memory" in the firmware settings if you have an IGP. The shared system memory is the amount of physical memory that the graphics driver can use if it needs to. If it doesn't use it, something else will; if something else is using it at the time, the graphics driver will be SOL. You can't change it, because you don't need to.
