R507 @ Mach 1

[RobinTHEOC]

Hey! How much does it cost to R507 mod a prommy mach1 ? And how are the results ?

Thx for all answers and advice :)

[solo]

fugger does it for 200$ if i remember it correctly

[CrashOv3r1De]

wow thats cheaper then a r404a

[chilly1]

And a better Mod it is..................
actually R507 is a better low temp refrigerant than 404 I get a few degrees colder with it.

[FUGGER]

I have not modded a vapo yet but it should be pretty much the same procedure.

I would need to test loaded to know for sure.

$200 and that includes return shipping (USA only) for the R507 upgrade. I have done several units and all are working great. Mach 1 and 2

[FUGGER]

My mach 1 will go beyond the -52c capable display and stay in error mode until I bench. It will drop to -49c with a regular P4c above 4.2Ghz while benching.

Here is my unstable screen shot of top speed.

hey fugger

is this mod good for 24/7 use?
does it kill teh compressor faster?

do u have temp comparison on Mach II stock vs Mach I 507a
what are teh temps going to be on Mach II 507a ?

thx

[FUGGER]

The mod seems fine for 24/7 use, it will reduce the life of the compressor some. Unknown as I am yet to burn one out.

With 134a I was able to reach -50 at idle stock speed.

Now I can go past -53c into error mode and stay there. at full speed I will drop back to -49c benching from the load.

[mrnuke]

with a low temp 1/4hp compressor w/ r507 and a baker block, is it possable to reach -80c?

What were you seeing at load pre-r507 mod? I'm seriously considering the upgrade and would like to know the improvement under load.

[FUGGER]

by the end of nature I was -20's just running that test with 134a. I was pushing my 3.2c hard @ 4.2Ghz+

[mdzcpa]

Thanks for the info.

BTW, are you still doing the mod for others? If so let me know and I'll PM you for details.

Thanks again.

[FUGGER]

I am doing the R507 mod, I have gotten units back out the same day for minimal down time.

[ctgilles]

:eek: You're so fast :D (*see the irony <-> USPS? LOL ;))
No really, if shipping a unit to you wouldn't cost 500€, you would've modded mine by now ;)

[PyroTeknik]

be cheaper to just buy the unit from a usa store and hae it shipped to him... then he covers return shipping :)

[LTi]

but then the price of the mod increases by the price of the shipping to his place ;)

so just changing from r134a to r507a gave you ~30° difference at full load? omg that's insane! - or do i just read you wrong there?

btw did anybody ever bother checking what an international delivery of a bit that size and weight would cost?

[chilly1]

What is your addy???

Not really, the best I have gotten unloaded with any captube with 507 is -77f, I got to -86F with a pressure expantion valve and an aluminum evap but had no capacity.

[Jvlk]

I have a modded machII with r507a..and i got -46 idle with 134a first....now it gets down to -70 with 2.8c stock volts...and when i run 2.8c@4.1ghz at 1.85v (Can't get it higher stable) goes down to -53 on display at full load.

[sky]

:slobber:
that is just awesome... so i guess i'll have to ask around for intl. deliveries - might be close to what the actual 507-mod costs.. darn, they don't even sell the old prom over here :( sp i gotta start searching for a cheap source in the us...

@chilly1
you mean me with that addy thing? if so, pm me

[NinCom]

oo shiit ! i really need to do the r507 mod to my mach1.. my load temp goes down to -26 =/ So if i charge it with 507 can i get down to -45 - -50C at load you think (1700+@2,9ghz 2.15v)

[chilly1]

You want the 507 mod PM me with addy and Email....

[FUGGER]

Chilly one is my HVAC engieer in Las Vegas. He has mastered the refill of the Mach1 and Mach2. contact in confidence. He knows what he is doing and knows to check/fix problems that have come up before.

NinCom, I dont use an AMD but I would drop to -49c on the display benching on a regular P4c 3.2Ghz @ 4.4ish Ghz

[[SLC]Tachyon]

Ughh.. sooo tempted to order a Mach 1 right now...

[[SLC]Tachyon]

Oh yeah fugger, was that -49C load temp done using the standard Prommie Mach 1 evap or a baker evap?

[FUGGER]

Stock mach1 evap head and original cap tube.

[baker18]

The temperature difference on MachI display and probe tape to the face of the stock evap is about 15c to 20c.

baker18

[FUGGER]

Yea, mach2 is very generous. I agree

That why I state the "on display" temp.

Mach 1 is the same................

[NaHeMiA]

wow that is damn fast fugger

better watchout bowman or fugger is going to put you out of business (*cough* Fuggers Mod Shop) :D

j/p its all good

[DisposableHero]

hey fugger do you do anything about the errors and beeps? or is that left to us to worry about

[chilly1]

were working on it... we can move the sensor to the suction line so it measures the temp there where it won,t go into error mode.

[CodeRed]

FUGGER,

Have you tried a R507 modded prom in high ambient temps?

Quite afew guys down under (on OCAU) are contemplating the 507 mod to their proms and I am a bit concerned that a hot Aussie summer could cause excessive head pressures (we're talking 35 deg C already and its just the start of summer ... cant wait for January :( ).

Dont want anyone busting a brand new prommy.


BTW : the resistor mod works great on a mach I for getting rid of the beeps. Just gotta re-calibrate it correctly.

[chilly1]

We get to 49C here in the summer but I usually run my computer in my house not outside.
25-35C should not be a problem, if you have high ambient you will lose capacity though but you would also lose with 134a.
There is an overload on the prommie and also an internal Overload these will open on high temp and are there to protect the compressor.

CodeRed What resistor do you use on the Mach1 ?

49 deg C, hell where on earth does it get that hot :eek:

In terms of overload protection on the prommmy, do you mean the bi-metallic switch cable tied to the condensor output? The one on my prom (mach I) is rated at 50 deg C +/- 5 deg C.

I used a 10 Mohm pot on my Mach I and lowered the value slowly until it added 5 deg C to the temp reading. I then subtracted 5 deg C from the displayed value using the P14 calibration value. Ideally you would use an accurate thermometer (such as a fluke) and calibrate it more accurately. Either way it will only be accurate over a small temp range (-60 deg C to -40 deg C ... which is where it matters :) ).

I have suggested this mod to several people and it is clear that Chip-con must have changed the thermister (on the Mach I) some time in the past as for 5 deg C offset my value ended up being 800 kohm, others have needed 4Mohms.

[chilly1]

Las Vegas, NV Hell on earth well maybe but we have fun ... Sin City...... I work outside most of the summer.. HVAC/R and Rooftops get to 140-150F (48-54C) And I'm originally from a climate where the temp is usually a lot cooler 95F(35C) max in summer.
Thanks for the heads up on the mod.....

Germany is $240 one way....

[Ewok]

yo fugger, when you do these r507 mods, do you have to have the fans on higher speeds or can they be left on the normal setting?

id go for the 404/507 mod but not if i have to put the fans on fast as that makes too much noise (especially the rear fan, the front isnt too bad).

i could do with the colder temps as it might help me push this 2.8 a bit higher, currently stuck on 4011mhz at 1.75v bios, and i really need 4100+ to max out my memory, im hoping maybe a 507 mod would push me over 4100? maybe even close to 4200?

what kinds cpu temp's did you get that?...idle/load?

i'know that asus p4x800 motherboard doesn't show
real temps ,but post them anyway

how much did you put that r507? or is't r507a?

[FUGGER]

I left my fans stock, they seem to do a good job as long as I keep the sides on.

[FUGGER]

CPU goes into error mode at -24c, need a mobo that can read sub zero correctly

[Ewok]

p4c's shouldnt go into error at -24, ive read as low as -30 on my p4c.

unless of course your trying to use the asusprobe crap, which cant read their own motherboards temp sensor properly.

[t800]

-24c in bios? my p4p800 goes N/A bios when bios cpu
temp is over -39c. but motherboard monitor can read
the sensor somehow, my readings are p4 3.6ghz 1.85
-36c idle and -27c load

[FUGGER]

My P4C800 is not connected to my Mach1, it is still in the cascade. Its a week old.

[Ewok]

any ideas how much i can look at gaining from a mach2 going over to 404/507? how much do people usually gain from this?

currently max stable overclock is 4011 at 1.75v. mb reading cpu temp at idle -29c, load -7c, evap temps -49 idle, -30 load.

PCP&C 510 with pots, mushkin lvl2, so mem and psu arent going to be a factor but i REALLY need to get this chip up to something like 4200 or more to get near the memory max and after the amount ive spent on this thing i damn well EXPECT 4200 or more with the quality stuff ive got in it (except for the crap chip and the crap 9800 pro thatll only do 397 core 354 mem)..

Here ya go Modded Mach II with 60 ambient and unloaded..
finished mod tonight. after finishing charging unloaded -68c on prommie and -56c actual on face of evap..12deg diff (tem.http://www.blairwing.com/images/mackIImod.jpg

Nice!! :slobber:
Great job guys.....

[daos]

i am very interested in modding my Vapochill PE. is this possible, and what kind of temps difference should i expect? FUGGER, i PMd you about this, so im looking forward to your reply.

thanks...

[FUGGER]

You got PM
