Yes, testing processors with LN2 is a part of my job. I also do product reviews and other stuff related to http://www.muropaketti.com

This LN2 cooling and other testing is my daily job. I'm the webmaster of largest hardware-site in Finland and I get paid for what I'm doing.

So what's your point?

CPU still works fine and actually we are already planning for the next test with liquid nitrogen

Earlier we tested Pentium 4 2,4GHz CPU with liquid nitrogen over 20 times and it's still kicking

We dry the components very carefully after the test with compressor.

Re:Hmmm, 145MHz FSB, 21x Multilier = 4Ghz - eh?

Hello,

We have modified TurboPLL-module on Asus P4T533-C motherboard which allows us to use higher front side bus.

Thanks to this module, when we set 145MHz from BIOS, the FSB is actually 186MHz.

You can check out the pictures of modified motherboard here.

Hello, That's correct. I was able to run the last test with 3998MHz CPU clock Here is the original size screenshot: http://www.muropaketti.com/bench/nw2800/superpi_39 .gif
