Did a bit of late night tweaking and I have got superpi1m down to 32secs, with ram on a 166mhz divider at cas2 6-3-3 1T, with my side cooling fans turning and prime 95 running the temps have never gone over 40C! This venice runs really cool on the stoc heatsink and this refurbed DFI 250gb motherboard. That mobo cost me £32 for a refurb and a 90day guarantee, best £32 I ever spent on a mobo! The dfi board has a huge number of memory tweaks I have 90% of them set to auto so I think I can get the TCCD memory running better.
Looks like a lot of tweaking to do yet.
