StarCraft 2 FPS Problems

Ok so i bought and installed Starcraft and am getting some fps problems on some maps even with LOW settings. I will list my computer spec's and tell me exactly WHAT needs to be "upgraded" first I appreciate it very much.

Intel Core 2 Duo e4600 2.40 Ghz 2.40 Ghz
2 Gigs of Ram
GeForce 8400 GS Pci-e 16x the 512 mb version


Someone also told me my computer can only use 3 gigs , so NOT to get 2 2 gig sticks ? anyone ever hear of that? i thought if it HAS the slots you can pack it with the RAM ? its dd2 i believe.

So theres 2 slots, why wouldnt it make use of 2 2gig sticks anyone know

 

I'm not familiar with Starcraft but it will help if you can tell us your current CPU, GPU, RAM, and Virtual memory usage whilst playing it

Task Manager will show you the CPU and RAM stats; Start > run Dxdiag > first page = Page file used/available will tell us the Virtual memory stats, GPU-Z will enable you to see the GPU load in use.

Can you find your motherboard make and model # please, it'll enable us to be sure about what CPU you could upgrade to.

Re. the 3GB memory limit, with all 32-bit Operating Systems there's a limit of 4 GB of RAM that can be utilised; this is only a rough figure as the BIOS can reserve some of the 'top' of the RAM for hardware like the graphics card(s), etc. For example: if you were to add 2x2GB to your machine right now, you'd probably see that Windows will report and use somewhere between 3 and 3.5GB. If you had a 1GB graphics card, then this would reduce to around 3GB, 2x1GB cards = 2GB or so usable RAM

The good news is that a 512MB (DDR5 is best) card is fine for most games and, if you really must use ALL of the 4GB RAM, you could upgrade to a 64-bit operating system.

The bad news is that you might have to lay out $200 or so for a good graphics card, similar for a better CPU AND the full 4GB of RAM PLUS a 64-bit version of Windows to get some of the latest games running well Much depends on the screen resolution that you'll want to play at and the engine of the game.

The above, if reasonably accurate, suggests that your CPU is pretty close to the recommended stats but the GFX card is probably way too low but your 2GB of RAM is adequate.

It all boils down to your expectations and how fat your wallet is.
