Today I cleaned the PSU and had a closer look in it to see something.
PSU_open_cleaned
I found a overheated transformer.

After all the cleaning I conneted the PSU-tester, if it shows something.
PSU_tester_connected
And really it shows something now, wow what a effect.
PSU_tester_shows_all_voltages
PSU tester says the PSU is OK.
Now I closed the PSU and set it back into V8-Xeon.
I switched the Power on and the machine runs till to the logon screen, then switched the power automatic off again. Pitty..
A next try to start the machine was not sucessful anymore.
Will order a new PSU now.

Although we are a bit out of the headline, I'm hoping you enjoy.
To running the hardware on its edge is a great challange.
I dont mention it, my P4 with AGP HIS4670 died also, PSU burnt out the third time.
So I have stiil my R3600 ATOM ION and my laptop i3 GT540M to crunch.
Looking and control the hardware is always necessary to run extremly.
I have seen latest GPU-Z 0.6.3 does not show CUDA on GT540M on my laptop.
I was also wondering about DirectCompute is not shown.

Have a closer look with GPU Caps viewer on this GPU:

14 days ago I shut down the machine to go to holidays. As I'm back I switched the power on and V8-Xeon did not start anymore. The light and the fans are on for a second and then off. On the display of the board is nothing shown. No selfest is starting. Looks like the machine eat a next PSU..... :o

(a little late, but it is worth to tell and show picture)
As I opened the case I was really surprized about all the dust in it. Last cleaning was sill two a half months ago.
Have a closer look on the picture and you see dust ontop of the grapicadapters too, Its not light, its dust.
v8-xeon_dustbunnies
The most dust is on the wires before the first cpu cooling unit. I had to think about any effective air-filtersystem in the next future.
See you the small space between the graphicadapters, no wounder to get high temperatures, not enough air can come in.
This is not a masterpiece of engeneering, the graphicadapters must be smaller in the part where the fans are to let more air in.
Better I should run still two graphicadapters on this bordlayout.
I could increase the performance using two adapters with dual GPUs. Maybe a mixed configuration, one from NVIDIA the other from ATI.
One of the main-problems are the high temperatures of the FB-DIMM, you know I had already temps over 100 grd Celsius.
On the market I did not found really good freezers for the FB-DIMMs and a lot of memory coolers does not fit.
I got a KINGSTON HyperX RAM-Cooler 2x60mm blue , but it does not fit, it's too big.
I need a 50mm and still 5 mm high to fit under the clamp of the 12cm fan of the left CPU-cooler.
Looks like I must selfcunstruct something.

Got the machine repaired after a general cleaning and demounting. :)

We see a constant ~90% GPU-load and GPU-Temp ~66 grd celsius, Roomtemp 26,2 grd celsius.
Looks good, my working horse is running again.

10th august 2012, I got a new milestone with my small i3- laptop gt540m_10Mio_distrtgen ;D
my comment to the FPGA:
The price is high, 1392 Euro for a PCI-Express-card with XILINX™ VIRTEX-4™ FPGA and 512 MByte SO-DIMM storage-modul
see this entry in my developer-book some years ago
Although if someone has access to all the hard and software it would be nice to have a seti application on a FPGA.
