Will these parts work together?

not sure how the PIC-E 1.0a slot will affect it, but it won't run it as fast as if you had SATA3.0 on the mobo.

Edit: Noticed the 3GB RAM....

1024 x 2 + 512 x 2?

Else if you have 3 x 1024, you might want to benchmark ram, then take out one that's "single" and bench again.
