Thanks to Peter – bob(nz), I’m now the proud owner of my first Kayl Cascade cooler – 2x 1.7HP unit. This cascade cooling unit was built by fellow Team Australia team mate, Kayl for another team mate youngpro (James) and was then sold to another team mate bob(nz) and now it lands in my hands.
While I am busy with work right now, found some time to at least start up the cascade cooler to check if it survived the trip from South Australia to Brisbane.
Took a few photos and 11.5 minute edited video of the Kayl Cascade unit starting up – quite noisy. At around ~49 seconds into video I tested out the cold bug bypass switch, so you see a momentary increase in temps to -91.5C mark then I turned it off to end up with coldest temps of -111.6C on evap and -49.3C on first stage.
Power-mate wattage meter measured a peak at startup of 2695 watts, and average operating power consumption measured from the wall was between 1775 – 1795 watts at ~247-249 volts mains power. Checked my electricity box and while I have 1 phase mains (10A) – all my fuses show rated at 16A, so nothing tripped the safety switch.
The compressors definitely put out considerable heat starting off at +55C rising eventually to around +88C to +93C. Definitely will need a fan to cool those compressors.
Long overdue, but here’s a video from Team Australia in world finals at GOOC 2009.
I did some testing tonight on LN2 last night and finally managed to grab a screen from latest SuperPi testing. It’s not as efficient as 2:10 CAS7 runs i’ve had at lower clocks but it allows me to bench very high CPU speeds
Here are some details.
EVGA CLASSIFIED E760 (S610 bios)
Intel Core i7 960
6GB 2000GT Corsair Dominators CAS7 DDR3 > Week 22, 2009
Nvidia 8400GS Graphics Cards
1000W HX1000 Corsair PSU
F1EE pot on CPU
80GB SATA Hard Drive
Windows XP Pro 32bit SP3
Been playing with my new Xeon W3520 cpu and managed to break alot of personal best benchmarks for max validation, max uncore frequency achieved, Super Pi 1M, 32M and Pi Fast on DFI UT X58-T3EH8 with just regular water cooling
Uncore Frequency @4645.6Mhz
After a enourmous amount of effort I am happy to announce I am official part of the sixes club… That is below 7minutes in superpi 32m and 7s in superpi 1m!
Achieved on two very different platforms. The 1m result on the enjoyable DFI P45 DDR3 board, accompanied by the Intel E8600.
The 32m result is on the Gigabyte X58-UD5 board, with the help of a nice Intel i7 965 cpu.
Now that I’ve found my max Bclk limit of 228-230Blck, it’s time to revisit max i7 920 AIR overclocks with HT disabled
Powermate wattage meter = ~280-295 watts idle and peaked at ~461 watts for total system power draw from the wall.
Room temp = 21.5C – 23.5C
Max screen capture capable @4680Mhz at 1.5875v bios
