What happens if i mix 2 sets of ram in a P4 system with different CL ratings?

[Raymond Lin]

Currently have 2 x 512 Geil ultra platinum PC3500 in my computer running in a P4 northwood in a Asus P4C800E mobo at stock.

The Geil is 2.5-3-3-6, and I wanna get some OCZ 1GB (2x512MB) DDR-400 PC-3200 CL 2-3-2-5 Platinum EL Dual Channel Kit to go with that.

Or some cheaper Kingston 1GB DDR PC3200 400MHz Non-ECC CL3 (3-3-3).

or

GeIL 1GB (2x512MB) PC3200 Value Dual Channel Kit CAS2.5 ?

Would it be ok? or would it cause stablilty problems? Which would i be better off with?

what will I have to tweak to make them run the same or it'll just do that when i put it in? Sorry i am being really dumb here, never OC memory before.

BTW, the Kingston is £50, OCZ is £65, and Geil Value is £65 too.

Ta, think i'll go for the OCZ then only a bit more and its cheap as chips compared to the £120 i paid for the Geil !
