Since I was looking for a cheap core duo to replace my 5400+ Mhz 3d stable E6700,I was lucky enough to get my hands on a little jewelry : E2140.
Not plated in gold nor shiny,just an ordinary piece of silicon who will live his entire lousy electronic life under a dusty regular intel box cooler.

And my itchy fingers dont stop when new cpu's are sitting on my desk, i pluged my regular P5K-E and starting to raise the bus.
Five by five mhz. At 450 Bus i was starting to look for my cigaretts.
When hitting 500,on the same crappy intel cooler,my chair was pushed behind to bend me towards the monitor as i wasnt sure im seeing it right.
520 made me pull the plug off and start searching for hte ln2 tube.Wife waking up in this neverending process of searching..Like usual.
Iwasnt sure if any ln2 was left after 2 weeks of normal life (ln2 free),but thanks God, some cold steam rolling down the dewar made my pulse accelerate a bit.
So, mounting my fast response tube was never easier.no isolation no nothing.

560 was my fisrt stop, and dunno why but i felt like testing the stability with 2k6. Which almost empty my dewar.
With the last drops,raising the bus a bit more managed to pull up a 4mb pi.
Setfsb and to 575 FREEZEE!! Temp were getting up -130C, -125..no ln2 left.
Just a sweeeet smile staying in my eyes, even now,20min after the incident
