    It turned out to be a crap - Powerchip T series for sure, they don't even boot at 2400MHz 8-11-8... :cool:

    In fact I was a bit lazy to finish it in 100% and show the pics, but unit is working pretty nice since I had built it. On the most cpus temps are around 65-70C negative, it's perfect for benching on...

    How you figured it? I bought these, because they have 1040 marking and it seems to be nicely binned PSC - that's my opinion.

    Bought these in this week:

    131890

    2x2GB RipjawsX 2200Mhz with original box and fan. I can't wait to test them :) I'm wondering if the can beat my best PSC kit - Axeram 2400MHz, which do 2600...

    On 250W load tester or on CPU? I think that Thuban on this vcore has more than 260W...

    Tested today on Phenom II X6 CPU. 4800MHz @ 1.8V wPrime 1024m - -61/62C under load. I don't think that there is cpu with more power draw. I have to finish insulation (only small part is uninsulated),...

    No, I didn't swap them - I have cut half of the pipes and replace them :)

    Now, at the output of SLHX I'm getting frost, with insulated HX and pipes. Previously I had couple degrees of Celsius...

    I've made another changes today. Shortened 1st stage captube to 1.60m and connected propane return before SLHX, but after interstage HX (before propane return was connected near the compressor)....

    Some pics :)

    I made longer load testing and so far I've got -57C @ 260W heat load, what is good, but I believe that it can perform much better. Discharge pressure still concerns me a bit, because...

    I'd use a water chiller with temperature controller. Much easier to tune and with 2-3l reservoir compressor will be turning on not so often.

    This HX on photos above turned out to be complete crap - it was impossible to braze it. I put all those captubes into bigger pipe (35mm) and it seems to be working better.

    Autocascade was...

    Yesterday, my friend ryba :) gave me a hint about SLHX. Today I bought some fittings and cut all small pipes, which I found in my workshop to make a SLHX.

    SLHX is 30cm long, outer pipe is 18/16mm....

    Today, I've brazed expansion tank to he unit, and lowered both filters (fortunately, no brazing was needed in this case, only some bending). Static pressure still seems to be high, but 13 barg looks...

    Unit seems to be ready :) Used parts and components:

    80 cm long HX before phase separator (6mm pipe inside 12mm pipe on CO2 return)

    20 plate heat exchanger

    2.7m 0.9mm captube on 1st stage
    ...

    Phase separator is ready, I only need to braze it. Most of the unit is ready, I have to order plate exchanger and new filter, because I damaged the old one.

    ...

    Thanks for your answers. I've found plate exchanger in good price, 20 plates, 315x73x52mm (costs about 70$ in my country). It's not that long as you mentioned, but still 50% longer than a standard...

    It's really interesting idea - now I'm really thinking about morphing it to autocascade :) I'll need only heat exhanger (I was thinking about 10 plate exchanger, exact the same which is working in my...

    Stripped 2x2GB kit of G.SKill PK Series. They use exact the same Powerchip IC as DDR3. They're marked 1030 (DDR3 are 1040), I saw other kit (PQ Series 1000MHz) marked 0630, so it means to me, that...

    My last unit (13300 btu rotary) was doing -52C @ 260W load and -58C idle, so I don't think that -60C is unreasonable ;) -70C maybe sounds a bit optimistics, but maybe idle or slight load like single...
  20. Killer Single Stage - Turns Autocascade 19300 Btu rotary build

    EDIT: I decided to make autocascade instead SS. See next posts for details.

    New build, this time I'm building really strong SS for myself. I'm aiming in -60/70C area, so it should be nice...

    If you keep liquid above 8-10C (depend on humidity) you don't need any insulation.

    Thanks for the tips :up: But in my opinion better cooling is the way to go. 8600GT core is so small, I had positive temperatures in load. I've noticed, that shader clock scales very well with...

    Project 8600GTX

    Hello,

    I had a simple plan. Connect working VRM from 8800GTX (bcoz all Evga stuff is too expensive for me) to 8600GT and make some scores. I bought dead 8800GTX and working 8600GT Sonic + and...
