OCZ memory question

I've been looking at this memory as an option for a moderately oc'ed gaming machine for my brother.

2GB (2X1024) D/C Kit PN-OCZ26672048ELDCGE-K

Anyone have any experience with these chips? I know he doesn't want to spend the cash for the plat rev 2 2x512 sticks.

The build will have: Asus P5LD2, Intel 630 3.0, Air Cooling, x800GTO2 w/ AC Silencer Rev 5, 2x200 IDE drives, OCZ 520 Powerstream

I don't see any reason why the memory wouldn't work with that system. The ram should have some overclocking room as well
