Zalman CNPS9700 cooler.
So far reached stable 440*8,5 3740
Tj max 80°C on small fft prime.
Proc @ 1.35 V (any less results in Prime error)
NB @ 1.2V
Dram 1.9 V (def 1.8) (timing instead 5 5 5 15 - 6 5 5 15)
What steps can you suggest to take to get stable 4K?

It's weird how much processor voltage you are using. I've got a very similar system (ok, better cooler) and at 400 FSB I am using 1.144 CPU volts for stability. Haven't touched my NB and DRAM -- still on auto. I know every system is different, but these are way way different. System below.
