So im building an apu system for my brother and I was wondering if 4gb of ddr3 1866 ram would be good. I have windows 7 32 bit and i dont want to spend 100 dollars on 64 bit unless it is absolutely necessary

APUs have a problem with RAM bandwidth. Long story short is: CPU uses RAM, but now the CPU shares it with the GPU inside with him.

So, in layman terms, your game will put all it things into (RAM) memory and you'll also need the GPU to use more (RAM) memory to process its own stuff. 4GB will be very close to cap what you can do and 8GB will give you more room down the road in my opinion.

In regards to RAM speed, yes, APUs need the fastest RAM you can feed it (and supports).

Llano (3x00-series) supports up to 1866, Trinity (5x00 series) supports up to 1866 and Richland (6x00) supports up to 2133, I think.

Cheers!

I also am just about to buy ram, does the ram size and speed effect performance or is speed the only factor that improves graphics? for instance 8gbs at 1866 as opposed to 4gb at 1866
