3 year old Pentium 4 640 running like a champ
I'm loving my old Pentium 4 640, as it overclocks past 3.4 Ghz and down clocks to 2.67 Ghz like a champ with my new Thermaltake V1 Heat sink, although, voltage is a concern, since one must push it past 1.462 V to get it to work at higher clock speeds, and i have already tested my Pentium 4 at 4.1 Ghz and at 2.67 Ghz stable
Overheating
Similar to Bambooz, my SL7Z8 is overheating beyond being usable after 2 years of factory-clock usage
i've got 2 of those SL7Z8 CPUs. both seem to be defective (the only thing they do is get hot ;)).
any suggestions what to do with it to get them working again? :/
to post something useful, i've added a picture ;)
stepping
how to change stepping overclock it!!
