I am currently working on a prescott, scratch that, "PRESSHOTT", I got it as far as 3.8 with 3:2 ratio, prime95 it for 8 hrs. no crash so it seems somewhat stable with my co2 rbx setup. At first I had 4x identical Crucial stix to run it, then I thought I could reach 4 ghz somewhat better with a pair of Corsair XL Pro stix but I was only stable with prime95 at 3.7 with 1:1 ratio. I did some forum research so that I could lower the multi at 14 but only to find out that my DO SL7E5 is stuck at 16 with my p4c800e deluxe board. Board is currently down and it won't boot up. I may have to reset the CMOS or something to that effect. Anyhow I am here to ask for advice on which a64 line to purchase for a better overclock. I have read some arguments and discussions on which one is best for overclock and it seems the 3000 or the 3200 is the top choices. I think I am ready for the amd cpu's for I have had some crash course on my p4. I plan to just purchase a cpu and a board so please any one, help me out?
