Trying to ID my board

[CPnUb]

I bought a gateway from a pawn shop for cheap awhile back and the Intel AA C45431-104 went out in it. I think it had a 2.3 intel processor in it (its been quite awhile)

Anyway, I've tried searching for it with little assurance to what it is exactly. I mainly just need to know what chip set it is (I think 478?)
If anyone knows or has a site where i can find out (or both)
I'd appreciate it

Just looking for reassurance so i don't have to waste the time when i order a new board.

While I'm at it... If my ram slots can handle up to 400mhz and i put 500mhz in it (1GB DDR overclockers) what kind of problems should i look forward too?

DDR that runs at higher clock speeds, will clock fine at lower clockspeeds. You should have no problems.

The board you have is Intel D845GVSR. All the info is on Intel site:
