Your existing CPU will not work with that motherboard. The AM2+/AM2 processor slot is for AMD processors only. For this motherboard, you will need one of the following processors: Phenom FX / Phenom / Athlon 64 FX / Athlon 64 X2

Answered originally by TimIsHectic:

Assuming you mean a bad framerate and not actual 'lag', the problem would appear to exist in your processor, as it is old and outdated. and only just fits the minimum requirements to RUN THE GAME, not run the game well.

Answer: You should upgrade your CPU to a Pentium Dual-core at least.

Processor: Minimum: Intel Pentium 4 1.3 GHz or AMD Athlon XP 1500+
Recommended: Dual-core processor, such as the Intel Pentium D or AMD Athlon 64 X2

Recommended: 1 GB RAM (2 GB for Vista users) Video: Minimum: 3D graphics processor with Hardware Transform and Lighting with 32 MB VRAM Such as an ATI Radeon 7200 or NVIDIA GeForce 2 class card or better
Recommended: 3D graphics processor with Vertex and Pixel Shader capability with 128 MB VRAM Such as an ATI Radeon X1600 or NVIDIA GeForce 7600 GT class card or better

Let me make sure, even if your motharboard supports 4 GB memory, A system of 32 bit (most users use 32 bit and among intel processors only intel core2duo/dual core supports 64 bit) wont show more than 3 GB of ram. its an operating system limitation.

But sorry to say, The max limit for your motherboard is 2GB.

Thanks
