While I was driving home yesterday I desided to pay a visit to my LN2 supplier which was located nearby. I left the place with a 20L can filled with LN2, naturally

This morning (while suffering of a massive hang over) I bolted all of the parts together and started to test the "new" container. To be exact the container is not new I just havenīt tested it with LN2 yet.

Well the container exeeded all of the expetations and the system ran perfectly for six hours.

The few first hours went while struggling with the P5B Deluxe motherboard which wasnīt working properly. Even for a slow strap the motherboard was definitely much more slower than it should have been.

It seems that Asus has done some changes in bios 0903 for better FSB overclockability. 0903 bios is ridicilously slow when booting with 533FSB+ speeds and it didnīt seem to gain anything in FSB overclockability. However with 0903 bios when booting with 333FSB+ the board can reach 15MHz - 20MHz higher bus speeds than with the previous bios releases.

After flashing in bios 0614 the performance raised back to normal.

Since the CPU can do 5.15GHz with only 1.53V at -120c, it is clear that the board is the bottle neck.
