good to know that.
JC got better temps when he placed those extra spacers, so I'm gonna have to find me some spacers and put a lot of them on the screws.

Maybe you should try these products that keep everything cool when the heat is on.

I would recommend the Artic Bandana's !

Sorry, 2 tempting :^)

WTF is that :^D

Now I'm at -3°C idle and -37°C on the evaporator, but with 1.75v Vcore.

Question: chip-con supplied artic alumina, now I'm wondering if ASII would improve my temps? Or ASIII?

ASII, not really. ASIII: yes.

The better the cooling the larger the temp difference is with better thermal paste. Get some ASIII now! :)

chipcon sent me as3 (two tubes) with my order due to some mixups with the payments... so it'll probably mean
1. you can use it
2. they like me
3. if they like me it oughtta be good if they give some more
:^D

I just tried something which I thought would give me a boost but result was worse then with my regular aircooling: just put my mobile airco against my case (sidepanel removed offcourse) and temps dropped to 24 cpu &15 mobo. A run off 3d mark with my gpu settings a little higher (325/315 >< 323/315) gave me 13425 points instead of 14050 and a giant crash just after the results readout. I even had to clear cmos to get the computer up again
???

Is there a component inside that can't stand low temps?

nope...
it's weird but that happens every now and then when you're playing @ the max... i ****ed up several parts not knowing where I'd gone wrong...

the weird thing about this is: afterwards I ran the tests again with stock cooling (@ 223/315) and I got the +/- same result as before (14043), so nothing is broken or so, it just seems there's something that can't stand low temps

your call your self an phase changer, but you don't have any AS3 lying around? "FOEI"
(n/o)

ASIII should be an 2~3°C improvement :D

I know... :bloos: :gay:

If there only was a store nearby that has got ASIII in stock...

I know for a fact that every component in my pc (my FSB speed, max absulote OC, vidcard speed) doesn't perform best went it's pushed to it's absolute limit, but just a few Herz lower.

A couple months ago I spend a few days benching my ram at every single FSB it would ran smoothly on and found an interesting conclusion: optimal speed does not mean maximum absolute Hertz, but maximum Hertz with no "errors" happening.

The sad thing is: you can't always see those errors happening. A vidcard that is too much oc'ed usually shows artifacts and whether the memory can follow at the high FSB speed can be tested with memtest86. But that's it. You can't really know whether your AGP port can handle 400Mhz, or a disk controller works flawlessly etc. When they produce errors at high FSB, it will often result in the fact the data has to be asked/sent once again (if your lucky, otherwise = crash) which results in a slower system than a flawlessly working system with lower FSB/GPU/Mem settings.

so there is a problem with the abitth7-II.

thanx to JC for doing all the fieldwork towards chip-con so they could get it solved...




"Dear Prometeia User.



It has come to our attention that a couple of customers have had some difficulties in assembling the unit properly the first time. It has however shown by thorough investigation, that these incidents except with one specific Mainboard (the ABIT TH7 II), mainly emerge from lack of understanding the two basic and most important features of the Prometeia Cooling System.





· The first being, the issue of proper thermal contact with the Core of the CPU. The fact that the Cooling head does not fully cover the heat transfer plate of the P4 on some MB’s is not an issue of concern - the actual Core of the CPU is much smaller. However, insufficient pressure towards the heat transfer plate is very much a concern, and the manual describes in the mounting instructions for the P4, how to adjust this pressure to achieve full and effective contact by adding spacer rings.



· Due to a difference in the threaded brass Stands on the mounting Clips, with respect to our original specifications, it is recommended to place 4 spacer rings on the screws holding the Cooling head in place. Units shipped out after the 4th of June have those already. Units shipped prior to that date does not have them, but spacers should be included with the kit.



· The other issue of concern is that of Condensation. The Prometeia is delivered with a very efficient Seal String, that totally prevents any vapour diffusion into the hermetic Cell, as long as it properly closes all gaps into the Cell, also gaps under components caught under the mounting bracket. Other important parameters of the Seal String are that it does not cure (harden), it is removable without leaving any sticky or greasy trace, it settles very quickly under appropriate pressure. It is not recommended to use any other sealing method or material, as that will result in formation of Condensation.



· On the issue of the ABIT TH7 II MB mentioned earlier, the matter is slightly more complex. Due to a couple of components placed very “unhandy” with respect to the Mounting bracket and Clips, and some improvements implemented to accommodate mounting issues on other MB’s, it is unfortunately no longer possible to mount the bracket and Clips in the proper orientation. If you are going to use this Mainboard please contact our Support department to obtain a new Clips and mounting bracket. If however you cannot wait and want to try on your own, you are welcome to follow the instructions provided in the attachment to this mail. Should you fail to carry out the alterations, you are of course still welcome to obtain the revised parts from us.



Please make sure that you have understood these issues, and do not hesitate to contact our Customer support, in case you are in doubt of an issue. If you consider these matters carefully, comply with the guidelines provided in the manual and this newsletter, you should not have any problems and obtain very satisfactory results with the Prometeia product.



Please accept our apologies for the problem related to the ABIT TH7 II MB. Orders shipped after today, will have a modified version of the Kit included.



Kind regards

Alteration of P4 mounting kit for use on ABIT TH7 II MainBoard

These instructions are only for users that feel confident they can carry out such alterations, and prefer to do so, in order to get going straight away, rather than resorting to wait for a new Clips and mounting Bracket from Chip-con ApS.



1. The correct orientation of the mounting bracket is with the wider end wall downwards. In this position you will notice that a few components are obstructing the mounting of the Clips in the Bracket.



2. It is necessary to reduce the height from beneath by 1mm of the single Tap holding the Clips in that end, so it provides additional space over the small component located just below it on the MB. Otherwise the Clips is likely to touch that component, which may cause electrical problems. It is recommended to cover the small components with 2 layers of tape for additional insulation and safety.



3. Just next to the centre (and only) Tap in the same end, there is an additional rather tall component on the MB, this is also in the way of the “leg” on the Clips, however since the mounting Clips is not making use of the outer mounting point in that end, this part of the leg on the Clips can just be cut off. Cut as close to the centre mounting point as possible without interfering with that, and at the outside corner of that mounting point. Make sure you make this cut-out in the correct end of the Clips where the brass stand is closest to the “leg” (narrow end of the Clips).



4. To compensate for the 1mm raised Clips position due to this alteration, it is required to add extra spacers in that end under the mounting screw heads of the Cooling Head, to obtain full and proper contact with the heat transfer plate of the P4.



This is the only way you can currently use the System on the ABIT TH7 II, sorry. Do not try to mount the Bracket and Clips and Cooling Head upside down, as this will cause unsatisfactory Cooling performance, and excessive un-evaporated R-134 to return to the Pot inside the Compressor under low to medium load.

We apologise for the extra inconvenience, and hope you will forgive us this blunder.



Kind regards

Seems everybody is waiting for some sort of conversion unit ;)

Ik heb maar drie spacers gekregen, kga nu is tussen mijn vader zijn spullen zien of dak daar geen goei vind, anders wordt het een bezoekje aan den Brico...
Dat samen met ASIII zou mij deftige temps moeten geven.

o, what a misfortune for you doc, but no worries, bring me the promethea and i'll take good care of it :D

no Bicker, that's not something you can use to fix your roof with :D

no ASIII? A SHAME

did you lap your core?

the prometheia included no less than two tubes of arctic alumina and two tubes of as3! this due to the fact I lost quite some money in double wire transfer due to a miscalculation in their price...


total price was 720 euro!!!!!

and I can't use it yet, because I need a new mounting kit...

so you got it Calantak...

:ws: :ws:

damn, I'll be the last one to get below zero :(

nice...I only got one tube of AA and no ASIII (hint ;))
Hope you'll get your conversion kit soon...

my pc is dead.
read the abit th7-II thread... on problems forum.

no bootup possible.
and no conversion kit.

it'll take some more weeks before it goes online and I promised it to JMke for at least some weeks

van poloke

hij heeft dus extra spacers gebruikt enzo...prometeia werkt dus toch redelijk goed met AMD XP
(Petrus op icrontic heeft ook geen goede temps)

mijn 'slechte temps' liggen dus aan mij ;)

Yes, but saw another "dead" MX-EVA3 on icrontic...third from four or five I've seen...

you smell rat?

or just incompetent ppl :)

last one (Leo) ain't dead

at last, my vapo will work at the end of the week :)
good news from OC-shop, the ordered stuff is on it's way.

me verry happy :love:

about time :super:

no, read it 2, but its poor quality control tho...

Ok this type of cooling rules hard, but damn the expence.
I would try that ****, but a guy with a small budget can never afford those things. I'll try and make something like it myself though (allways do it yerself, y'll do it better) :king:

Anyway the cooling only getting just below the 0°C is pretty weird. It should really be a lot colder, if the hardware would be a little better. About a year ago I saw the pc from the guys of cryotech. They had a system running a athlon 800 @ 1.86gig with some nice freezer and the temps were about -25° idle if I recall it correctly

those are evaporator temps... the idle evaporator temps on these machines (prometheia and eva) go to -38 and more...
Even with evaporator temps going as low as this, idle temps still won't be below -10...

I have indeed been mistaken. the temps were the evap temps, and It wasn't -25°C but -40°C.
My memory let me down, luckily I found that site again, too bad they don't sell any homepc anymore

http://www.kryotech.com/index2.html

idle results around -40 on evap are what we see mostly at the moment.

got the vapo up and running, not a better result :(
I think my ram is maxed out ...

172x16 highest setting and it is't stable...

hmm, going to shop and get my 2.26, it's just in
see what this baby can do.

if it is 172x17, it would be nice, but not what I expected
:grum:

temp: evap : -18
cpu 8° idle, 25° stressed.

ram maxed out? at 3*172... possible...

maybe the chip is at his max... it's possible you get your 2.26 well over 3 gig, don't worry...

should indeed go "way" over 3 gig with vapo. I can run 180x17 on it-7 with 2/5/2/2 stable on air

Bicker, you got DDR, Ive got RDRAM, not the same :)

Damn, did try anything that could help, nothing..
this :puke:

someboby knows if the wiretrick is the same as on the 400 mhz versions ?
didn't find anything about that on the net...

fsb@172 is fsb@172 no?

ask here, it's were all the overclocking guru's hang out. :)

Damn, so long waiting for the conversion kit and no improvement... :grum:
