Problems with epox board or ram?

[mentalcrisis00]

Here's the deal

I'm running an Epox Nforce 4 ultra board, i run my old 333speed 1GB set of ram with it and everything runs great, no crashes runs BF 2 at 70 frames.

I put my new corsair dual channel 2GB set of ram set the timings to 2336 and i load BF 2 and i get the following errors and/or blue screen "Physical Memory Dump"

My question being, is this a motherboard problem or is my ram dead?

thanks
