need some help, i dont really no much about memory, could someone tell me wot CAS means and is CAS 5-5-5-15 bad, is it the lower the number the better or the higher the numbers the better?
DDR2 works fine with 5-5-5-15, obviously not the best, but it should work and it will give you a little more headroom. I would either run a P4 on a 1:1 ratio or a forward ratio like 2:3 or 5:6. Intels like more memory bandwidth.
