This is a P4 1.8A overclocked to 2.52GHz/140MHz FSB using 1.575v. Stock Intel Cooler. This chip does 2.7GHz requiring 1.65v but I dont want to run it on a 24/7 basis. Motherboard is Asus P4T533-C with 512MB RD1066 Memory.

It seems like with the newer P4 C1 stepping there ARE some clock to clock improvement over the current B0 stepping. Currently this includes the P4 2.66GHz and the 2.8GHz.

Xyzzy: I think the Intel 845x chipset does NOT support ECC at all. Thats why you will have problems when using ECC memory. Either not POST or not 'using' the ECC function.

Daffy: I do notice this. Sometimes notice that Prime95 is running slower than it should be. No idea how it happens it just happens.
