Its up and running

[Circaflex]

So my sweet single stage is up and running on the quad. However i have a few questions.

1. Dr Frosty doesnt work in Vista x64, what can i use?

2. Abit Uguru temp reading shows like 120C, what should i use to monitor temps?

[n00b 0f l337]

Try CoreTemp.

[Circaflex]

doesnt work in vista x64 either, any other ideas? Also what does Dr Frosty do?

Speedfan?

Speedfan?

will try that out tonight, off to work. Will floodback hurt the unit? I didnt have any load on my quad while i was tinkering around and i could hear the "popcorn" is it really bad for the machine?

Floodback isn't good. It can damage the compressor pretty quickly, probably best to avoid causing it if you can.

But if the unit has floodback problems while the PC is running, that might be a problem.... (the unit shouldn't have floodback while there is SOME kind of load, even if it is just idle).

[Circaflex]

well my builder told me id need to load 3 cores up 75% because its a little overcharged and i was browsing around trying to download orthos and i could hear floodback.

If you're looking to use the unit 24/7 and it gets floodback at idle, you're going to run into problems. Run WCG (world community grid) or something similar to keep the processor running hot. Surprised to hear that it's flooding back at idle temps, that shouldn't happen ideally.

Time to start crunching. Thats way to much load needed to stop the popcorn though, definitly needed a suction accumulator or something or different tuning. Hmmm hope it doesnt need that much. But throw 2 cores on crunching or maybe three.

Thats not a little overcharged.... thats a lot overcharged. It shouldn't have any floodback even at idle if it is done correctly. You should have it retuned.

[n00b 0f l337]

Its tuned for 275W, beleive it has a small accumulator as well. Very hard to avoid 275W not flooding back. Wanted 275, got 275, but yes going to have to keep the load up. Idle can be almost zero watts of load on some CPU's, the best way to be is simply keep the load up.

I want pics!

This is a unit I built and yes, it's tuned for 275w and meant to run 24/7 at 275w. I ran an identical unit at 4.4Ghz on my G0 Q6600 at 1.625vcore crunching 4xPSP-Sieve clients, core temps were in the single-digit positive C values and compressor discharge and shell temperatures were within spec. 275w was specified and 275w was delivered while keeping with compressor spec, it's a simple de-tune process to drop capacity. Unit should have 8' 4" of 0.031" capillary tubing and charged with pure r507. At 275w the temperature at the base of the evaporator was -21C.

note: my tests and notes were with a 22C ambient, for some reason I failed to plot all of my evaporator temps through the range of tests, not sure why I didn't record them.

Im folding now and its all good, im gonna pump some serious volts through it probably thursday and bench, ill get you guys pictures im tired, and its late for me ( i have class tomorrow). Thanks for the unit gomeler!

Speedfan works, showing -9C while folding with my quad at stock, does that sound about right? Or do i need a remount? Froster unit shows -25

[[XC] gomeler]

-25C on the evap and -9C on the die sounds like a really good mount. I typically experienced 15-20C delta between evap and CPU temps, so you are doing great on that aspect. Let me know how it goes, I maxed around 4450Mhz on the other single-stage as I didn't give it more than 1.65v plus I was trying to stress all 4 cores.

[tiborrr]

Not sure if anyone mentioned, but CoreTemp doesn't show negative temperature as it's calculating the temperature from power draw.

Any link to Mr.Frosty software?

Hmmm, I would think the best way is to actually build one with the correct components and design to handle the load.

It's not hard to get 275w if the unit is designed for it, but overcharging one that isn't to that extent is not good. Too many people are claiming high capacity when all they are doing is overcharging, if the unit won't idle without serious floodback, it's not designed correctly. If you need 275w, then use components that will handle that load, don't just keep pumping in gas until you get the load then try to convince the customer that it's normal to have to run high load all the time to avoid killing the compressor.

I've got it setup with 8' 4" of capillary tubing, an NF11FX, Chilly1 Blue condenser, small "accumulator" on the suction line, and a wrapped capillary on the suction-line. I didn't just take random components off the shelf, slap them together, and throw gas at it until it held a load. I could have de-tuned this system so that it held 0w without floodback but then it'd die with anything over 175w a la VapoLS.

The issue with quads in general is the huge swings in loads so you've got to have a high mass-flow going through the evap. Since this entire unit has to fit in a single-stage case, I can't simply throw a large accumulator into the chassis to deal with the floodback so some compromises had to be made.

So... what would you have liked me to do? Tune the system for zero floodback or tune the system to hold a processor above 3.8GHz? If there is a magical secret, please tell.

[Circaflex]

BAH my raid crapped out i need to reinstall, ill get pics and benches tomorrow (its my day off). Im worried about the short amount of time during the windows install that i will get floodback, will it be fine for that portion and right when vista installs start folding?

[Pandrone]

If i were you and it's constantly flooding back liquid refrigerant too the compressor i would check the unit for schrader-valves (service-ports) and then let some gas out, just small amounts and check when the floodback stops, then you probably will have a long lasting good unit

I'm thinking that the builder of this unit did not tune it, as flooding back is Never good!

[[XC] gomeler]

I am not going to suggest venting a regulated gas and I'm going to assume Pandrone didn't read this thread. Sorry to hear about that RAID setup, I've thrashed many a setup while benching, thankfully I only use a 10GB partition on 500GB drives The unit will be fine with a little gurgling while you install Vista, she won't keel over and die on you. Goodluck with the folding, just got my 9650 up to 4650Mhz on a single-stage for 4-core folding, time to churn out some points.

[[XC] 2long4u]

Why don't you not use the phase until you get your computer setup and the appropriate background programs setup? Then once you get everything to where you have a high load, then overclock the chip.

[Circaflex]

because how i have it setup it isnt feasable for me to redo the entire phase setup, a 30min install shouldnt be bad on it.

[Circaflex]

will flood back make things unstable? I get part way through vista install and then i hear popcorn, install comes to a hault. I reboot and it wont even get passed me entering the serial number. Is floodback causing some sort of problem in that sense?
