Intel Pentium Presler XE overclocked to 4.26GHz on air

The Inquirer got their hands on Intel's Presler Pentium XE 955, which features a 3.46GHz clockspeed along with 2x 2MB L2 cache and a 1066MHz. They managed to overclock this processor to 4.26GHz - on air! This was done wiht Intel's 975XBX motherboard.
Boy, was I wrong... by mistake, I changed the default x13 multiplier not to x14, but to x15 and, when I rebooted the system, the magical 4.0 GHz clock frequency status appeared, yet I only upped the default CPU voltage by 0.025 volts. The CPU temperature as per hardware monitor jumped from 80 C to 90 C, and then pretty much stayed there over those 15 mins as I checked all the new BIOS options, some of which I saw for the first time on an Intel board.

Anyway, let's go all the way to a nice, more harmonious x16 multiplier - yes it worked too, and I got an even nicer 4.26 GHz clock with an extra 0.025 volts on top. Hmm, counting dual cores, this is now a 17 GFLOPs PC system - once this was considered a supercomputing power. The CPU temperature went up to 91 C and, again, stayed firm there over another 20 mins or so - the system also rebooted to BIOS fine several times at this setting.
