About binning.. Sampsa and I tested 4 CPU's under LN2.. there was just a lot of back up CPU's. Don't take it too serious.. it is just nice to take that kind of pictures.

So many back-up CPU's huh? :):)

Anyway, the fabrication process on this CPU's is just amazing, it puts new meaning in the phrase "sub-zero benching". I really hope we'll see more of that inte new CPU's.

Nice results, nice car, nice cpus, nice boards... everything nice! :)

Did you test the maximum "fsb" of the DFI Boards?

Wow, liquid Helium. Isn't that very very expensive?

Great benching, looks like you had a great time : D

Thanks for sharing Dave, it sounds like it was a great oppurtunity and experience! I hope that I'm able to do the same someday, I've been reading about this stuff for years but have never checked it out in person before!

How did you change the N2 out when you wanted to start the LHe? Wouldnt want to have a solid block of N2 lol.

Nitrogen will not solidify even at -273c :)

plus you have to use LN2 to get the pot to -196 in prep for the LHE otherwise it would take too much helium to bring the pot temp down :)

Is this supposed to look like a very large man sat on it?

I thought it froze around there, maybe thats something else. Did they just cool the pot and then let most of the LN2 evaporate or did they just add in the LHe along with the LN2?

Nice pictures and results. :toast:

Yes.. first you let the LN2 boil away and after that you start to use LHe. There was some really weird liquids in the pot after we end our session :eek:

haha we have road rage, now were have LN2 rage :rofl:

Thanks for sharing :)

Excellent results mate! But I have question...isn't it Windows Xp with CrossfireX (4 GPUS)???? There is a new driver which works in Xp?? :P

Thanks!

No it is Vista. You just click "adjust for best performance" setting and you have the similar look on your vista.

There is OS limitaton with GPU's. Quad CF works only in Vista and Windows 7.

It could have been liquid O2 in the container after the benchsession, where temperature was still below -200C. Huminity is very low in Vegas, so no idea about the quantity as it looked like a lot of liquid was in the container.

Yes, when we lifted "lid" which was on top of F1 EE and liquid helium feeding hose, we saw some liquid dripping.. but I think it was liquid air not liquid oxygen:

http://en.wikipedia.org/wiki/Liquid_air

"Liquid air is air that has been cooled to very low temperatures so that it has condensed to a liquid.

Since gaseous air has 78% nitrogen and 21% oxygen, the density of liquid air at standard composition is calculated by the decimal percentage of the components by their respective liquid densities. Its freezing point is -216.7°C and its boiling point is -194.35°C."

Anyway.. very cool :up:

Liquid O2 would not be something you would want to find in the pot...Especialy if you are a smoker =))

Depends on your location and availability liquid Helium here is about $50 a liter :(

I was just happy to sit and watch these guys.
For years I've read the posts of people like Macci and Sampsa and I was lucky enough to get to meet them and see them in action.
Another was this guy SF3D. Gentleman with a big smile having a great time.
Very sharp guys who know "their stuff" and gentlemen to meet.
No ego BS just nice down to earth people.
I can't say enough on that point.
All the people I met were the kind of people you want to know.
Guy's enjoying the hobby amongst friends and that is what made that day so special.:up:

i could have not said it any better!!!! can not wait to meet up again.. anyone still in vegas? im heading back again tomorrow! w00t!!! :up::yepp::p::D
