Which stepping on a P4 2.8 GHz "C" processor

[stianhg]

I'm about to buy a new CPU and I have plans of overclocking it, using watercooling. The obvious choice is P4 with Northwood core as I've read these have great potential. The 2.8 GHz version seams like a good choice with its friendly price, but which stepping should I be searching for? I have the opportunity to make requests regarding CPU stepping to some of the webshops.

SL6WJ and SL6Z5 are the 2 steppings that people seem to have the most success with according to overclockers.com's database.

your best bet is zipzoomfly

just email their customer support and they'll look at their stock

ask if they have any sl6z5 and they should reply back within a day.

I just received my ZZF 2.8C and it was a SL6Z5.

I have it currenly running at 3.4 GHz (Zalman 7000 Al-CU) and that is with Kingston PC2700 memory. Others have reported that this S-Spec should hit 3.5 on air and 3.6 with "extraordinary" cooling, if that helps you any. But I do not plan on pushing it to the limit.

I run my M0 SL6Z5 at 3.5 without any problems. Burned in running Prime95 and SuperPI simultaneously - didn't get very good times for some reason 😉. I am not pushing it and I get about 44C temps when benchmarking with 1.55V. Just make sure you get a good motherboard, fast memory, a quality heatsink and thermal paste and a stable power supply.

Thanks for your feedbacks!

I will ask for SL6WJ and SL6Z5.
