In search of the golden FX57 w/o frost bug @-90C

[Dumo]

Then...start benching @-86/84C evap. temp.

[Dumo]

Ordered Opteron154 from Egg ..Hope it will fly like this 150...

[Eldonko]

Awesome, good luck DUMO. My 150 doesnt have cold bug either, although I only have a peuny single stage heh heh.

Dumo, clear out some of your PMs. Your box is full bro.

[/hijack]

[Dumo]

Done

[Hell-Fire]

Done

Roger that, thanks.

Back on topic....In a few days, I'm gonna receive the cpu which I consider the Holy Grail of all AMD cpu's :



Too bad I won't be able to get it into the -100's

Surprises me that you dont own a cascade, honestly.

But with your auto it will run with less temp swing (load<>idle) @ high vcore...Thats better than an instant -105C evap..

I don't own one by choice My feeling is why be like everyone else when you can have something unique yet sufficient for most intents and purposes. It also helped that AMD was starting to release cold-bugged cpu's and an autocascade would put the chips @ a temp which was ideal

You're right - but tbh, and autocascade isn't designed like that. Usually autos have more of a deltaT than multi-compressor cascades. The reason why mine holds a load so well is that we haven't even begun to challenge the capacity of this unit. Chilly1 says it's possible to tune this unit to HOLD @ -110C temps

[Dumo]

Its the way of the future....less cold, more load stable cascade
Only the masters can tune it right.

Don't forget that it's Energy Star Efficient too! lol....(well at least it only uses one compressor).....

I am using my FX57 with Vapochill LS stock and at -50 degrees evap. temperature and -25 degrees cpu. There's minor coldbug at these degrees and it doesn't boot up above 310 mhz fsb and I haven't tried with lower temperatures. I am willing to give it a go with some Ln2 setup of my friends.
It has a good stepping as much as I heard from here. It's CABNE 0530 APMW

Don't know how it behaves under LN2 , but with DI it had a small easy to control coldbug if running > 265-266 HTT , once temps are lower then -45 (actual CPU temps) it goes into blue screen (that's why there's memtest running in background )
I wish i could test it with LN2 but i can't find a place where i can buy some

LOL, if you mean "like everyone else" you are referring to the maybe 5-10% max of the overclockers here that use cascades?

Not diggin' at ya, but I doubt they are that prevelent compared to single stage cooling. There are obviously a ton of them here, but I would say compared to overall member strength the numbers would be relatively small.

I still have tons to learn about how phase change works in general, but are you saying that an autocascade adjusts??

it's sorta a cascade, but with one pump driving multible kinds of gas. iirc, steve's autocascade is actually.. 6 stages?

LOL...kinda sorta....

Phase change uses COMPRESSORS and not "pumps" Pumps are for watercooling, women, and people with small wee-wee's LOL

The compressor in my autocascade actually only compresses one gas (or blend of gasses) and in turn that gas cools another gas which cools another gas which cools another gas and so on.....my unit is unique in the sense that it utilizes 6 stages in which 2 different gases are interacting with one another inside of a heat exchanger. That allows the unit the ability to condense such gases as R1150 (ethylene, boiling point @ -104c) and R14(Tetrafluoromethane, boiling point @ -128C) which on a normal single stage would be impossible because of the pressures necessary to do so. I'm FAR from grasping the concept behind an autocascade, but you know it's complicated when Chilly1 says that he "has no clue what's happening in the heat exchanger area" of my unit and is offering a trade of a true cascade for my auto so he can take it apart and analyze it Basically it does the work of a dual compressor cascade with just one compressor.....

@ Hellfire: When I say "like everyone else", I'm referring to people who use phase change. Tell me - how many single stages you see around -> A LOT. Now how many dual or triple cascades do you see around -> Enough that you probably can't recall the exact number. So tell me, How many AUTOCASCADES do you know of that are currently up and running and in use? If that's not unique, then I don't know what is

ANY phase change unit (including single stagers) can be adjustable as long as the right valve is correctly in stalled on it.....
