In part. The BIOS has a lot to do with it as well.

High-end systems, for commercial graphics work can have several Gb of memory......

Does the bios come with the motherboard or what does it come with?
 
Technical questions don't belong in GCRD. Please refrain from doing so.

Thanks
 
The amount of addressable memory depends on the architecture and the chipset as well as the BIOS.

The maximum number of addressable locations = 2 ^ (address bus width). For a 32bit address bus this is 4.3 x 10^9 locations approx.

Each location is a size the same as the data bus width. For a 24 bit data bus each location is 24 bits (3 bytes).

So a system with a 32 bit address bus and a 24 bit data bus can address approx 1.031 x 10 ^ 11 bits of memory.

This is:
1.29 x 10 ^ 10 bytes
1.26 x 10 ^ 7 kilobytes
12228 MB
12 Gigabytes

12 Gigs is alot of RAM but how is there room enough to put that many sticks?

I was not using an actual example, purely a hypothetical example.

In most systems the chipset can handle x banks of RAM at a max. band size of y MB.
