the only way you will know how cold it really runs is with a good fluke meter set to use a j type or t type thermocoupling.
I have a R404 modified Mach I unit and have resorted to the resistor trick to stop the screaming controller and continuous shutdowns - which sort of defeats the purpose in a way.
What controller (if any) would you recommend could be used to replace the Carel unit so that true temps etc could be seen? I am serious thinking of getting a replacement controller and a suitable j or t type thermocouple to get around this issue once and for all.
Thanks in advance for your comments :toast:
The Carel controller is perfectly capable of handling much lower temps, all that needs replacing is the temp probe. See the Heavy Discussion thread Bowman made for more info. I think the controller can use a J or K type thermocouple, which are capable of -100C. See the other thread for my thoughts on that.
Hi Darkcyde
Have read the post, and it is as I thought. The standard IR32Z controller that comes with the Mach I is only for use with NTC probes - limited to -50 degress. This means that I have to change both the controller and the sensor to get over the issue. :)
The question is - is there a better option than the Carel controller available? For me here in NZ the Carel controller and probe will cost me approx $600 NZ pesos :eek: (approx US$350) :D
Before I race out and sell my kidney to fund the purchase I just wanted to clarify if I had other options :D
Another option would be to mount a sensor on the suction line as close as possible to the evaporator. This will read a few degrees higher than actual evap temp (keeping it within the Carel controller range), and is actually a better control point as far as function is concerned.
Bob: I dunno why, but when I read "NZ pesos" I fell outa my chair. Being canadian, I can sympathise :D
I guess you're right about the controller, there are different versions for the diff temp probes. DOH.
I'm beginning to think that the whole controller needs to go too, but I'm not sure what would replace it.
Yes, thats tuff. I just tried the CPU test, can "only" do 974 on my Cascade Prommy R404a going at P4@3200@4300Quote:

Fugger use an ES, so better FSB and Ram speed:rolleyes:
Hmm I believe I got around 1100 CPU with an FX-51 in 3D 03 :eek: I am sure it was well past a thousand I believe it was in the low 1100s at 2.85 GHz
Thats niceQuote:

I can't get any corsair twin R 3200c2 here. FX-51 and MOB no problem...
Do You have a link to some store in europa, that have Corsair R ram?
:toast:
wow, impressive ;) i've my promy moded to r404a and 1 extra cappilar meter, i used 1 hour to calibrate the gaz and at at 1.8v and max cpu overclock at the end of 3dmark 2k3 i'v -43 on promy chill control
if i use ice on the condenser i get somthing like -48º on chill control
and you with r507, no cap mod an condenser at air get -49 :slobber:
i'm verry interessed to try r507 :D there is no need to change compressor oil and the it afects compressor like r404a right? just recharge with r507? :D
going to buy r507 :D
:toast:
EDIT: only one more question, we are talking about r507 right? not r507a

Don't do it. I now from Danfoss factory, the compressor can't take it.
Its R507a.
R404a is a mixture and R505a is almost the same mixture without R134a. When you vacuum the system, it might bee unsufficient, and when you fill R505a it work!?. Its because its not vacuum proberly, and the mixture actualy is R404a !!!
IF you vacuum proberly an fill R505a, the compressor can't take the pressure, og you can't fill to a desent cooling-effekt but only a "cold" system to do screenshot.
PS: my R404a system is under -54/-53 the most of the time. At the end of 2k3mark my temp is -50/-49...
at 1.81 volt...
:D
My compressor seems to handle it just fine.
I like R507 better than the R404
:slobber: how u get that temperatures? only with a charge of r404a i get -41c full load at 1.8 with an extra 1,2meter of 0.7mm capilar i can get -45cQuote:

:D
there is any other good mod? :P
and i can't buy r507 here in portugal in bottles <10kg :( 10kg is to mutch and to expensive
cumps
Ok guys i have went ahead and pulled some infor for everyone.here is the specs on just 404a and 507a
and you can see the actuall differance in the makeup and temp between the 2.
now you can see the actuall differance...no hype here just the facts:D
about 1C?
Yep very close to the same. only .5c reallyQuote:

and this is one of the best charts i have found...so you guys can look at all of them ...here it is...in pdf format.

cool
As Bowman offen have said: test and ajustment;)Quote:

I use a huge akkumulator-drier on the returntube.
The kap-tube is twisted around the return tube.
The tube to the radiator is subcooled with a vapochill!
Big fan on the radiator and the kompressor
--And a little more!
You can get R507 from a A/C- company you only need 60 g
bring the prommy to them, it cost almost nothing...

lol, but they where so happy bowman,,,,, why did ya have ta go and break the bubble..... isnt 507 just 404a with a tad of 23?
well i should have pulled the specs up a while back..Quote:

i coulnt remember excate ,was thinking 1 or 2 c differ.
the next step in refrigerant would be 410 i would think.but that will be too much i believe for prometia compressor to handle.
Can you do it again, an upload to ORB.Quote:

It alwais interesting to compair results.
FUGGER 977
Tom Holck 975 at 4320 Mhz
CPU 1 FUGGER long ahead. CPU 2 I am a little better, same MOB, and CPU, but FUGGER ES lover multiplier.
FX-51 might be very fast in CPU1 ? :bows:
::Thanks for make it clear Bowman
Damn...... 4764 Mhz.
..... gives me a woodie.
What About R410a?
I have a Kryotech R404a, and i plan to change the gas and use it in my A64 3200+... :)
