V8-xeon is death  Cry
After the last shutdown I restarted the server yesterday. But surprisingly the machine did not start, it hung up while starting the OS Vista64. I tried the secure mod, but nothing helped. After initial loading of some driver the machine switched off automatic. After this happened, the machine comes no more over the BIOS selftest. So I decided to open the case for a general cleaning. I took off all 3 grafikadapters and the main memory.
Here a look at the empty machine.
After cleaning all tools I let the 2 GTX470 off.
Now still one graphic-adapter GTX570 is inserted
If I switch the machine on, the display on the board runs till 28 and then comes 29 and the machine switched off.
Port 80h POST codes
No good sign. Looks like a defect memory or chipset.
I will took off the memory and clean again, hoping to have a little more luck.
If you have some specal tips, they are welcome.

V8-Xeon,
after recleaning, I could run once through the BIOS successful till to the access on the disk, then switched the PSU off.
So I can hope the board and chipset is not damaged.
Looks like I need a new PSU.

btw.
 i3 GT540M got 5Mio primegrid

Hi,
here are some pictures of our latest cuda app's running on my i3.
Installer v0.38 used to install.
GT540M slightly oced
GT540M_sensors_Lunatics_x38g_win32_cuda32_2_wus_running

picture from our beta test
running 4 akv8 and 1 x38e at the moment of downclocking
the downclocking is solved now.

Thanks to the developer team and the beta testers, and all people who are involved.....

download the v0.38 installer and try the new published app's -->downlod v0.38

i3 gt540m crunching 3 akv8b and 2 x38g
while running 3 akv8 vlar on CPU the temp was goi~g up to 84 grd and the CPU downclocked from 2,6GHz to 931MHz.
Yeah, akv8 is a toaster

Hi Jason,

CUDA3.2 & INTEL's Compiler
Package ID: w_ccompxe_2011.1.127
I used the patch CompilerIDEPluginUpdate.zip to avoid the rules-file error sucessful.
The rules-file error is gone.  Wink

Projekt: MonteCarloMultiGPU and Projekt: MonteCarlo does not sucessful compile with Intel Compiler
ptxas hung up  Cry
========== Alles neu erstellen: 91 erfolgreich, Fehler bei 2, 0 übersprungen ==========

So far, we must wait for the next update.

heinz
Intel Composer XE 2011 Update 4
meanwhile I have CUDA4000 installed.
It compiles now the two MonteCarlo projects.
...
Compiling with Intel(R) C++ Compiler XE 12.0.4.196 [Intel(R) 64]... (Intel C++ Environment)
========== Alles neu erstellen: 93 erfolgreich, Fehler bei 0, 1 übersprungen ==========

I close now the issue.

To use the right hardware to support AVX and CUDA
Laptop Erazer X6816 now available in Germany.
with Geforce-GT-555M 2048MB VRAM
699 Euro, really a hot price.

Don't make the same error as myself, bought a laptop with i3-390M, (P6630 with GT540M) although it is launched at Q1/2011 it's previous generation.
See difference of i7-2720QM, i7-2630QM, my i3-390M
I bought it too early, could'nt wait.  Cry

Time to say thank you to all readers not lost their interest on this thread.
In autumn I will be hopefully back with a repaired V8-Xeon making some good numbers ....

Thanks to all looking up here.

As my v8-xeon died I bought a Tablet PC "AIRIS One PAD" 10-inch-infotmic-X210-1GHz-Android-2-2-OS-Tablet-PC-With-GPS-Function like this one
I equipt it with "32GB mcroSD Class 10" card to hold all my data.
It's very handy and runs great, a very useful toy.
I like small formfactor of hardware.  Grin

Most of us run a little bit o'ced GPU's and and are already confronted with the downlocking problematic.
Therefore it's worth to post something about it here.
I had installed Nvidia's driver 275.33, later 280.19 and BOINC 6.12.33 64Bit and run into the downclocking trap.
That means, always if I stop BOINC and Start it again, the GPU clocked down to 50% of its frequency and come not up again.
And if I use EVGA Precision to set the frequency up nothing happened. It was not possible to run in full speed again till to the next restart.
Now I'was going back to driver 267.21 and BOINC 6.10.60 and the downclocking did not happen again. EVGA Precision works as it should do.

downclocking - upclocking
~~~~~~~~~~~~~~~~
On the picture you see what happen when I stop Boinc and then start Boinc,  the card clocked down and up again as it should be.

...driver version unknown...

Hi Heinz,
  I am currently playing with nvApi , which is linked into Boinc.  I haven't looked in detail what interface they use to get the driver, but I suppose it's possible they use some outdated methods, or some other method than recommended.

For other purposes I made an extremely primitive test to see that I could access nVapi, 7zip archived exe and example screenshot attached.  If this shows the correct driver on your system ( instead of Unknown '...' ) then I might dig deeper to see what they might be doing wrong.

Ignore the stuff about view modes, it was just a trial to see if I could dig deeper into some system information, and it may not work for all systems.
