AMD A8 5600k GPU problem

[Jow Nel]

So I recently bought a pc with the ff specs:

Processor AMD Trinity A8-5600K 3.6GHz (3.9GHz Turbo) APU Buildin HD 7560D
Mobo FM2 Gigabyte GA-F2A55M-DS2 rev1.0
HDD Internal: WD Caviar Blue 500GB SATA 3
Ram Gskill Ripjaws x 8gbx1 Ddr3 1600 CL9

my problem is the allocated memory for my built in GPU is only 780mb... I already set the bios gfx configuration to frame buffer size forced to 2gb... My friend got a lower specs which is a a4 w/ 4gb memory dual 2x2gb but his allocated gpu memory is 2048mb... why can't I have the same allocated memory? my specs are better in terms of apu and ram.

Might try setting BIOS to optimal default settings

I've done that but still the allocated is 780mb... I'm really wondering whats wrong... do you guys think it has something to do with single stick ram?

Might be, but don't really know, it may put a max on what it can draw from a single stick regardless og the sticks density

If that's true then I think I should go for dual memory... but still I need to confirm that your theory is right...

Should be easy to try, borrow a couple of sticks from somebody, as stated I'm not sure it's just an idea
