Agree with moving this to "Problems". Did not mean to "bend" your thread. I am easily side tracked. :
i seem to recall on my report card, "easily distracted", and like any thread on these forums it eventually ends up discussing GPUs. Anyway's i put together all i can think of in a thread in Problems.
Meanwhile, deuteron has fused a few tasks, and thanks to some wingmen, validated. Still running 16 concurrently, temps still under 56C.
Following the idea of some of you I emptied my piggy bank and tinkered such a "only CPU cruncher" (expandable with Graphics Card later on).
Housing
Corsair Carbide Series Air 540 - Midi Tower EATX (my favorite). Added some more supports and replaced the two front fans outside to make mounting of a SSI-EEB Board possible.
Mainboard
- ASUS Z9PE-D16/2L with two sockets LGA 2011
- 2 x CPUs Intel XEON E5-2660 V1, used ones for $65 each, watercooled by CoolerMaster Seidon 120V ver.2
- 2 x Kingston ValueRAM - DDR3 - 16 GB : 4 x 4 GB - DIMM 240-PIN - 1600 MHz / PC3-12800 - CL11
Operating System
Windows 7 Professional, ordered as used from German ebay for $20 (in Germany - and almost in other EU-countries too - it is now possible to deal with "used Software" including splitting of license packages !). No problem with activating, updating was a bit confusing.
Crunching
After a "test phase" with some "Gamma-ray Pulsar Binary Searches" now running 32 "Gravitational Wave 01 all-sky I" about 17 hours each.
That's it ! Uhhhmm, no, I have one more Mainboard, two CPUs, a PSU and a case ready to build a identical second one. I only have to search first for another money-box which I can plunder ...

Could you tell me your CPU temperatures and what frequency they are running at?
I'm still exploring a bit.
Currently running 28 tasks, taking ~18hrs each.
running 16 tasks, ~11hr
Temps 52-59C (although it's probably needs a cooler room!)
Current Speed: 2200 MHz
That seems to more closely match my experience on the 2660's; I'm finding the 24-26 range to be best, while running 6 GPU tasks on two boards. Either Arthur bought magic CPUs, or his cooling solution is getting them to run at max turbo. I'm fairly certain I've set my BIOS for maximum output.
Either Arthur bought magic CPUs, or his cooling solution is getting them to run at max turbo.
I noticed your and Arthur's are Family 6 Model 45 Stepping 6, Cache 256 KB whereas i see Stepping 7 and Cache 20480 KB.
Interesting, I see that. It appears that data field is populated by our level 2 cache, not the 20MB level 3. Perhaps a read error, we using Windows and you Linux, or we having the Stepping 6 CPU and you 7? To the best of my knowledge, the only difference between your later iteration and ours is VT-D virtualization support.
I did briefly test disabling the level 3 cache on one machine based on a manual suggesting this may speed up an application that is maxing out the memory controller, but I changed it back after realizing my work units would be completing sometime next century.

looks like a very "clean" setup. But there is that "water stuff" again and the "hose" plumbing. I am just not that brave. Great looking setup though.
RE: After a "test phase"

I looked at your results, and you are indeed completing in 17 hours. I cannot get 32 units to complete in this time, even with quad channel RAM.
Could you tell me your CPU temperatures and what frequency they are running at?
Mine, from HWMonitor:
2x2660: ~60c, 2700MHz typical.
2x2670: ~55c, 2600MHz typical.
Very nice Arthur. The closed

Very nice Arthur. The closed loop all with in one cooling seems to be an easy solution. Those EEB boards are large.
Which Corsair PSU did you use?
