In 3DM01, it would be the Northwood EE clock for clock just because that benchmark uses the cache immensely. But, for a max score it will depend on how high the Prescott will clock to beat out the EE or not.Quote:

On other benches showing pure CPU power the Prescott would likely win.
Damnit still no tripple digit temps here :D
-97.8C is the best this thing can do in idle mode.
I did some real testing with the evap on CPU. And was really happy to see that it worked quite nicely.
First test was with uninsulated evap on 2.4C+AI7 board running at the max the mobo could do in stock form (~310x12 3.7G) running Vcore at max value (1.9V set in the BIOS, 1.85V actual).
Looping 3DMark2001 got the evap up to -81C zone.
Then I put some insulation (not optimal yet) on evap and tried a 3.0C+P4C800 combo that would run SuperPi 1M at 4206MHz with R404 modded prommy (evap at -45C).
With the cascade cooler the CPU would run the test at 4406MHz and evap temp didnt get any higher than -83C. So obviously the insulation helped quite a bit there. Idle mode in WinXP at 4.4G evap temp went below -90C (-94C was the coldest I saw when in winxp)
I located another somewhat broken cryofreezer too :D
The only thing that was broken was some silly battery and temp probe (I replaced the 12V batter with PSU 12V line and it would start up and run nicely).
This one has 28cm3 copeland on 1st stage and some Bristol comp (seems to be a bit bigger than the copeland one) on 2nd stage.
btw, I'm using protective gear when I play with the cascade:

LOL!! That's really funny...However, the work you're doing and the results that you are getting are Anything but funny...Great job! :toast:
btw, We should all wear a cool looking protective suit like that! :D
what's a cascade? sorry, i'm a phase change n00b.

and meet me back here in 3 days :D
approx how much would it cost to build myself a Phase change system? And how do i cond. prevent w/o voiding warranties? Danke sehr :toast:
Looks Like a white version of those guys in the old intel commercials ROFL:DQuote:

Tha picture of macci ( or is it ? :) ) made me LMAO . :D If it is then bloody sensible anyhow !
Actually, it is a good point on safety. Having read the differences of opinion on cascades from the experts, the use of dry ice ( producing CO2 in quantities ) and using LN2 I'm wondering who will be the first overclocker to really hurt themselves or worse :(
An extra 200Mhz on the P4 is nice work, with the extra freezer being sorted out and the P4 EE ( 999Euro as pointed out ;) ) on the way looks like it could be very promising.
I bet that -100C goal is like a red rag to a bull ...

if you want me to cheat (using existing equipment moded (no offense macci) wit a computer evap) i can have -100c tonight.
i prefer to make my own, makes it all that much more satisfying.
if it means that much to you let me know, im at my shop right now.
Well actually he has one other like that but even bigger in his back pocket so.... What do you think a XT would do at those temps?!
i just got here.:D :D
I don't think it means anything at all to macci aprt from the fact that -100c would be a nice number to get and it's a means to an end.Quote:

You seem to want to be able to get the coldest setup around whereas macci just makes it to get a good 3dmark score and in the meantime accidently pummels you into the dust celcius wise ;) .. so no point going on about how he did it :)
cheat ? by using old equipment, you sound like a yank being beaten by a European :D
By the way 2 years ago it was -47C in Finland where macci comes from. so he got half way to your temp by just opening the window .. ( joke :D )
"i can have -100c tonight"
Go on then, lets see the money

Hmmz, you change the evap ? What was wrong with the old one ? Or is it your new freezer ?
*edit* i see you have a new freezer and your working on it ;] How long is your heat exchanger ?
the first one will be GPU cooler so I put GPU evap on it :D
nothing wrong with the other, its just going to the other cascade.
heatxchanger is around 10m
Hmm, only 4m longer than mine and looks much, MUCH bigger !
Is that -105C shot made on R23 ?
Yup R23 is all I can get.
what pressures you got? r23 is at 4 inches hg vacuum at -85c. youd have to be at like 40 inches hg to get that temp. what size compressors are u using?
it has some nice vacuum yes ;)
2x21cm3 nominal capacity 778W
heatxhanger hot side at -40C (as seen in the bigger pic)
