My Mach II on 404a & 60cm cap tube

[wilso]

Hi all
On the weekend I just had my Mach II gassed with R404a (from R22) and the results are awesome. The dude also added 60cm of cap tube and it works very good, he didn't think adding the usual 1.5m would be good, so thats why he went with only 60cm.

Here's what my 2600+ Mobile can now achieve

I can also make the CPU get into windows @ 3194MHz but i haven't got a screenshot of that yet :)

Nice work bud:)
What sort of temp decreases did you see?
Is the dude in australia or did you send to him?

Yeah he is in AU and he's my mates dad, so it was done for mates rates ;) :D

I've kinda worked out from going from R134a to R404a and a re-insulation on it, it dropped about 16-18 or so. Hard to tell accuratly, just going off the LCD at times & MBM5...

Will do a comparison over next few days once I've removed 90cm of my cap-tube...!

Awesome, be interesting to hear your results.

what part of australia are you from
did you order that mobile into australia, or have they finally got them here now

Im from Victoria, and I won this CPU on Ebay (came from Canada), but I ended up paying a bit more for it compared to purchasing one from an overseas online store... Oh well :)

Nice OC, and what about temps on evap and proc ?

Well, at the above speeds the LCD reads (even though its inaccurate) -60 idle and -51 while priming. So your guess will be as good as mine for temps on the CPU... :)

could you check up SuperPI @1M & 8M plz :)

i've a XP-M 2500+ an it's going only with LiquidCooling to 2,6Ghz and i'm sure, that he would go that far too, with an VaporPC-Cooling...:(

sometimes i wish, that i would be rich:D ;)

1M - 35 seconds
8M - 6 min 36 seconds

Once I get my FSB up they should improve :D

nice stuff going on.

[martinakerman]

Can you explain how the AC guy did to re fill the mach 2?
like pressure?
vacuum etc?
All info you can share with us.
thanks

Yes, that would be very helpfull as i am about to do this very thing. I was hopeing that i wasn't going to have to change the length of the cap tube but oh well..

Any AMD above 3ghz is damn crazy ! with more then 2v o_O
wow dude thats damn fast, congrats :)

I'm building my own vapo around the baker block (i already got :)
what do I need to get around those temps ?

:toast:

Systems are not designed around a block, nor around a compressor. They are designed around a specific heat load. They will work okay above or below that heat load, but that is their sweet spot.

I don't change the capillary tube length "usually" on the mach II when upgrading the gas I simply install a new filter drier, triple evacuate and recharge so that Iget best temperatures, I base line it by having the room temp at 74F and charging so that my suction pressure is at 4 inches of vacume. Then I check my frost pattern and apply a 100W load and add or substract a very little as at a time for best temperatures. Usually on the machII the temperatures will land between -68 and -75C on the display actual temps wil be between -58 and -70C. On a couple of systems I have removed a little cap tube 6 to 10 inches but usually don't have to. The actual amount of gas in the MachII is simmilar to the prommie, remember that the manifold set holds enough refrigerant to overcharge the prommie.. so be careful not to overcharge.

[The Byter]

what kind of heatload this mobile is putting out ?
150W ~ right ?

what do i need to get the same temps ?

[Gary Lloyd]

Changing the refrigerant is relatively simple and straightforward, and doesn't even require a deep evacuation, much less a triple evac or a new drier, if the system has not been opened to atmosphere.

Changing the cap tube length is far more complex, time consuming, and expensive.

IMO, altering the cap tube is not cost effective.

just save up... :P

nyways..nice oc

Thanks Chilly and gary, i am printing this thread off and bringing it with me to the Refridgeration guy so i reference it while i'm trying to explain what i want done. Thing i'm wondering is i don't have any Tecs/Pelts so i wonder what i can use for a heat load. :confused: I ordered my Mach II finally from Kit-Tronics, they were a real pleasure to deal with and i ended up talking to "greer" for 3 hours on the phone. <b></b>If anyone is planning on buying a Mach II i can't see why you would go anywhere else.<b></b>

thats a good idea....but when i shall i buy a S939-System + GF6800U ? :stick: :D

Haha, -62~63°C Idle, -48°C @max Load (might be more heatload than you have). I didnt change anything on my captube :D
