"David versus Goliath?? .. I hope you all remember the end of that story! And please check back often since we are just about to start extensive testing of VapoChill's overclocking abilities!" ...

"Well since I have two verified PIII450's that works flawlessly on 140MHz FSB (630MHz) I was very interested to see whether i could push them even further :) .... + 140MHz fsb is high bus speeds - and especially the quality of RAM (random acess memory) and a capable AGP card will be of outmost importance when trying to push a system past this front side bus. On the other hand - I have a extreme stable 3DBlaster 4MB PCI card at hand. The stability off the motherboard will also be of high importance.... At the time off testing I had four motherboards in house - AbitBX6r2 / AbitBH6 / Aopen AX6BC Pro Gold and AsusP3BF. I also had three types off +133 MHz RAM (128MB dimms) to choose from...
I got very dissapointed to start with --- I actually didn't get past 140MHz front side bus with the VapoChill - on any of the motherboards... Just the same speed I could achieve on AsusP3BF with a AlphaPIII cooler attached to the CPU !! .. Well - I have experimented with cooling off the bx chipset in the past ... And did something radical ... I mounted a 53watts peltier on the back off the bx chip and a 23 watt peltier on top off it ( limited space under the VapoChill CPU box ) ... Off course I had to cut out a opening in the plate behind the motherboard to mount a 60 mm fan on top off the peltier heatsink.. The fan mounted on the front peltier had to be mounted offcenter - not enough space under the CPU box.

I used the AbitBX6.rev2 motherboard flashed with the MW bios. I fired up at 143MHz front side bus / 2.4 core voltage....and after 'chill' (Aseteks own program) halted the boot for 60 seconds the system went straight into windows -- 100%stable..."
