Here you are:

Holy crap I remember that massive insulation on the evap :lol: Wheres the hold down?

i've never seen so much insulation on a cpu before :woot:

Afi --> Two stage with pure R1150 Ethylene in second stage.
One of the worlds strongest cascades :D

Nice going Tom.

I just love reading about your cascade Tom

Good one. And good luck with the pi times!! :toast: :slobber:

/Grau

Welcome back to the action Tom, the king of SuperPI, from all the members of Team Japan :toast:

Very awesome :toast:

I see you're using a 7800GTX I believe... Try it with a PCI card :D

It's a 2 stage but I think the best ever made :D

going sub -120 at full load. That means a FX or a 670 going 2volt+ 64 Bit OS system. I can take more than 250 wat at that load.

Thanks :toast:

Yesteday I have made a nice M32 at 18:29 and was going to post in Japan. But then I saw OMEGA's results at 17:51 :slobber:
I whent back to try some more Pi aktion

WOW! That looks awesome! What size compressors? Home made evap? IIRC you said you had some medical refrigeration engineers help you build it? -120C loaded on a two stage beats the living crap out of every cascade I've ever seen :slobber:

Really impressive cascade you've got there Tom! :slobber:

Its home build Evap head, the first one used a Prommie head but if I recall correctly Tom said that the later ones wasnt top grade quality.

It's two 18" compressors. We first build a "small" one with 15" to make some test :D
The main thing was to get below -50 degree at first stage, with a massive load af more than 1000W. Then the R1150 can be put to work. The engineers that helped me, said that this was better than going 3 stage. Then I made the coolinghead. We first used a modde Prommy head in the small 15".

Tom, do you still have the Prototype one? Wasnt it -118c it hit or something like it?

Right the prommy head at the erly March I was nice, later they was dropping
in quality.

Yes AH^DK I still have the prototype look at picture 0017

Yeah. -50c seems to be the magic singlestage/first stage temp to get :D Whats 18" mean? What HP rating?

prommi head isn't something you can use for a cascade...mine gets freezed at only -55°C on my modded one and I think tom really needs this phat insulation.
i had to give it a +2cm of armaflex until it was cooling without giving me water all over the evap.
this is professional extreme style...high quality test setup with impressive temps.
this must have took you A LOT time but it was worth it :toast:
i think you can use this instead of ln2...doesn't matter what you take imo - it just won't bring alot...compare to team japan's ln2 runs...it's not that far away even they still hold the WRs....i wish you all the best for the WR's...just run RAM maxed out and get the records back to europe :woot:

Yes, from Danfoss in Denmark, they make some nice one.
On the prototype I used freon on first stage. Now it's R507.

thanks SoF

Tom, do you remember what my FX-55 hit under load at 3550mhz or over if you used it in it?

Mig der er Alex fra Tweak :)

The Cascade can take your FX-55 to 3730 mhz this gave the first 22 sek in SuperPi

http://www16.big.or.jp/~bunnywk/superpi.html

The record still stands.

FX-57 can bench at 3850-3900 Mhz but the memkontroller going below 200 FSB within 5 minutes when the temp drop. And after 10 min it won't boot.

YOUR CASCADE IS TRYING TO EAT THE BOARD!!! seriousy nice results though, and good luck on all the world records.

Really Nice Tom. Cant wait for the 32m record to go below 17:50.

Nice thanks Tom.

Yup still waiting with anticipation to see some 32M Action.

wow thats freaking awesome! I like the pic that shows another unit attached to the video card. Methinks its time for some 3d along with the Pi! :woot:
