works fine with primegrid, cpu-usage now down to 7- 10% (tpsieve_1.38)
the machine (P4 Northwood 2.6GHz) shows ~50% cpu usage total while crunching.
This shows: a single CPU can feed a Graphicadapter like HD4670 to crunch

25th april the machine had 2.250.000 pg-credit

Its hot here in the Rhinvalley since 2 days, we had outdoortemperature over 30 grd C already
Roomtemp=25,8 grd celsius
GPU2_470_101_grd  :'(
All temps over 100 grd C makes me trouble with the hardware.
Looks like I need a watercooled solution....or a compressor-cooling like a refrigerator.

If temps are not going down a bit, then I must shutdown my crunchers.

V8-Xeon is dead again.

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

Ordered now a PSU tester unit to see if PSU or board is dead.

PSU tester does not show anything, if I switch the power on, the display of PSU tester goes short on, then the PSU did switch the power automatic off. The PSU is definitely dead.

So I will looking for a new 1200W PSU in autumn. Now in the summer if temps are up 28 grd I can't run the air-cooled V8-Xeon.

By the way today my i3-laptop-gt540m passed 8Mio_distrtgen

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

I found a overheated transformer.
PSU_transformer_E4220_defect
PSU_transformer_E4220_defect_closer_look

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.

More than 180 000 hits on this thread now
Thank You to all users still looking up here.  ;)
~~~~~~~~~~~~~~~~~~~~~~~~~~~
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.
(Errorreport done)

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

(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.

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.
See FPGA thread
