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. ;D

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.

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 I haven't looked in detail what interface they use to get the driver, but I suppose it's possible they use some outdated methods, or some other method than recommended.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.
