1st time Prommy User: AMD temps

[jmke]

Hi ,
was wondering of any of the techheads can crack this problem :)

I installed my prommy this way ->
http://www.madshrimps.be/upload/jmke/prom/P5310258.JPG

onto a 8DRA with XP1700+
now first time installed it and temps were in the 18°C region in the BIOS while sitting there 5min

after a little checkup I bumped into this:
http://www.madshrimps.be/upload/jmke/prom/P5310260.JPG

on the Prometeia site they advise to use more spacers to give more pressure.. so I did.. I then screwed the thing back together this way:

||||spring|rubber

| = spacer

now the DIE of the XP makes full contact with the evap. but apparantly there still ain't enough pressure as the temp is 9°C in the BIOS

is this +/- normal?
when using 2v & running at the max. this setup can go without unlocking the CPU (12.5x200) and using 2v vcore the temp goes to 11°C in the BIOS

is this normal? can I optimally use the Prommy while using it in the way I set it with (as in: without the case on top) ?

do I need more spacers?
thanks for your advice , it's pretty impressive to see the CPU @ 9°C while the room is at 30°C (yes we are hit by a very warm temp. in Belgium atm)

Just to set your mind at rest on my barton at 3gig temp is the bios is 25 - 30*c evap temp is -28 to -32

The temps on the 8rda+ are measured from the insocket thermistor, once you seal the socket up the remaining air in there holds heat, plus the boards mosfets heat the bottom of the board up quite a bit. This is what causes the high temperature readings.

The temp goes up in the bios when you push the Vcore as the mosfets get hotter, not the CPU. Use your evap temp to judge your temps as this seems to be more reliable.

The temperatues in the bios are semi usefull in an aircooled situation but when using a prommy they are absolutely and totaly innacurate and are not worth looking at all.

Providing you are getting a good mount with the evaporator you will be fine.

The pic you first showed was a very bad contact, make sure your evap isnt being twisted by the hoze.

I'm lucky that the socket on the 8DRA is placed as it is, it fits perfect for the Prometeia without any force on the hoze, I rechecked contact after a 2nd mount using more spacers on the screws & this time it seems I have full contact with the XP die

thanks for the confirmation that my readouts are "okay" :)

now I have to get this XP1700+ unlocked for some higher Multi's =)

Cool, let us know how you get on.

Awwwww. That looks painful for the hose. Aren't u afriad of cracking the hosing. The looks of the thermal compound on the evap. head. looks like u need more tightening of the screw heads. Its not making full contact like it should be.

I thought i remembered reading somewhere that the prommie was more efficent because the evap head was above the compressor, in your case it isnt . Do you here a bubbling sound while in use ?

that doesnt make any sense.... like this, the hose goes up at first, then down, and gravity makes it nearly impossible for unevaporated fluid to go that far up back to the compressor. So its actually a little bit more efficient this way.

Although I have personally run the prometeia like that as well, I wouldnt recommend using it a lot like this though jmke.... the hose doesnt like it that much.

Also, a temperature of +9C on an 8RDA is perfectly normal. Even with a prom that was 15C colder than a regular one I had more than 10C under load on an 8RDA.... temp reading sucks a§§

thanks for the input!
I'm planning on installing it the "normal" way, but was testing the setup and found the temps a little bit weird to me.. as it was first time going vaporchilled =)

Antec Lanboy on top? :)

immerse the radiator of the prom in a watertank and use a watercooling setup (if you have one) to cool it ;)

temps drop a lot, but depends on the quality of the watercooling.

[jmke]

lol, good idea =)
but just sold my WC , but do have a 172Watt pelt extra lying around :)

Ive been thinking of doing this myself, but ill need to make a new case to do it.

Im a bit scared of taking the prommy to bits as well.

Does anybody know the approximate wattage that the condensor puts out (bowman ?)

[jmke]

darn CPU craps out @ 2380Mhz with 2v vcore :/

on air it did 2192Mhz with 2v

Actually, there's is a issue with running it that way. When the hose is ran up and then back down to the block, you're creating a trap for the oil inside the freon, which prevents it from making it back to the compressor efficiently. It's prolly not hurting anything to run it like that for a little bit of time, but I would not recommend running it that way for too long. Eventually you'll be running it with the majority of the oil trapped at the evap.

just for testing now, gonna put an Antec Lanboy on top, small enough to fit my small space @ the appartement
