Massman said it really well. TWKR did show some potential during the weekend.

Me and macci did not have too much luck, cause in these 955 ES CPU's there was few, which did not scale under -200c tempratures. The fisrt we tested did not boot at -230C anymore. Luckily Massman and Giorgioprimo was testing very nice chip on LN2 at the same time and we just carried the setup to the table where Lhe pipe was and started to go lower on tempratures. That CPU did scale well and we "overclocked" the helium tank by shutting down the safety valves + feed the tank with some gas. I think only overclockers are brave enough to do that with LHe dewar We just aimed to 7GHz and when we got it time was running out. If I would have known in that point, that we will have more bad luck with CPU's I would have done the 3D runs directly after that.

On sunday we tested two motherboard and one CPU under helium again and the CPU had a cold bug. It did 6750 validation easily under LN2, but when temperature was getting up to -240c the CPU did only 6.4GHz anyomre.
I think we all can accept, if CPU does have a cold bug at that temperature

Well.. luckily elmor was running his Gigabyte UD5 in the second room and we just swapped the setup. At that point we put the pressure to the max and closed all the safety valves
Temperature was under -250C all the time in some runs and that did help a lot with that CPU which was being used. No cold bug, just scaling all the time.

Well, now we have a lot of experience of runnign LHe and how to use these dewars + pressure controlling. I think we might have to do some more runs in the future.

Nice weekend for sure and this event was a great success, with sick scores. Thank you guys! You are the best and you all know it too

Pictures etc. coming a bit later.
