Viking.. puh! The norwegians are vikings, we gave Ireland a living hell back in the days.. ;)

That Prescott has to manage 7Ghz thru 3DMark01/03/05? It would be a blast!

Yeah and we gave all the other Countries in Europe living hell :D (Atleast the ones you can reach by sea)

Actually the Norwegians were Danes back then :D
Our hero, Tordenskjold was born in Norway. It as danish territory, though..

The norwegians became "danes" much later..?

Yeah perhaps. I don't really remember my history-education. Just thought i had to strike back for calling us non-vikings :D

Sorry im a n00b :stick:

Cold Bug is one reason why cascade is better than ln2. Few years ago it was littlebit different. In those times cpus loved cold so ln2 was the best way to froze your cpu. One reason why cascade is better than ln2 is that it's very difficult to keep the temperature stable if you use ln2. When you use cascade you don't have to think about adding ln2 to a container. Just turn the compressor(s) on, wait that temps are going down and have some fun :banana:

You couldn't be more wrong

Intel doesn't cold bug
-120C is FARRR to cold for 99% of the AMD chips out there
ln2 lets you have -19c to -190c if you have a good unit. Much better variable temps.

Is that so? Sorry my bad :) Some one told me that thing on muropaketti's forum(heya FINLAND). I just thought that this same problem is with every cpu. But is that -120C loaded or unloaded temperature? I just wondering that if it is unloaded it won't keep your cpu that cold, so that's why I prefer cascade that ln2

Actually I have heard most of the 670's will not boot up lower then -120 but once in windows I have had mine as cold as -160. ;)

I have sub -120 loaded at 2 volt full load both AMD and Intel.

I have no favorit, only the fastest is best!!! FX55 was nice. FX57 bad Intel well 7 Ghz is not sufficient to do 3Dmark better than 50k.

for me cascade is best because I can keep it more stable. In most bench records I have to messure tweak and try again. Thats hard with LN2.

that is what I try to say earlyer when that some dood ask that why cascade is better that ln2. I wish that I have enough time and experience to built cascade or autocascade. Maybe I'm too old for this oc stuff.

Hehe, 45 and feared by lots of people I assume, dentists aint populair :p:
NaaH, I dont think theres "to old" in OC buissness, dont know if I'll keep on, but I think so... Im only 18 btw... :\

Tom, can you please show how the rig performs in AM3 / 01SE, eventhough its AMD-land - 7ghz P4 should kick ass :D

EDIT: Tom, plz warn when you decide to turn on cascade, I bet it affect the power-net all over DK :banana:

-120C loaded... Thats a one of a kind cascade. Chilly1 and even PCice can't touch that. It's 2 stage right? Cap tube or expansion valves?

Amazing cascade. As AFI said can you please tell us waht is used to feed the evaps and if you are willing can you please share some specs on size/type of compressors or gases used?

Thanks

IIRC it is made with two times Danfoss SC18 and expansion valve on low stage. They tried to make it with captube, but ended up shortening it way too much.
I agree it is one of the most extreme coolers ever built :)

I think he also said it was pure R1150 on the second stage and reached something like -50 on the first stage with 1000w load.

One of the worlds strongest cascades :D

Nice going Tom.

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".

That was the goal, yes. With the SC15's as i understand it.
I bet it is a bit better in this one ;)
I know he is not happy with tho prototype - his wife complains a bit over 3 cascades at home, and it only does -112 loaded :D

Tom, nice rig, not only powerful but clean. Is that case custom fabbed?

And what of 3DMark benches??
