Anyway this problem is "solved" by asking less WUs. Since the other day, my RAC has continuously raised, I don't really understand why. boinc.exe used to use like 12h of 1 core per day (one eighth of the CPU) which doesn't add up with the raise I see. Even my other computer see a raise and I have not touched it for ages (server use), so I guess it has to do with the SETI crew.

My RAC has a bit more than doubled since 30 July after making sure I had all the latest KWSN software configured on the PC's. And shortened my queue. Maybe the project had something to do with it as well.

I saw posts from Raistmer, Joe Segur etc about shortening the queue but did not see any info on what is the "right" queue size. Mine is now 3 days' work. What is about "the right size" for quad cores with CUDA video?

Don't trust the 9400GT's host, it has 42 invalid WU's completed, and loads of 'Completed, validation inconclusive', a Reboot probably needed.

my 9400GT requires regular OS reboots  :(
With last drivers it starts to do CPU fallback. Anower weird manifestations was before... crap card :(

About correct queue size - it should be determined experimentally.
look at task manager. ig boinc.exe takes no more than 1-2% of CPU - all ok.

Raistmer - Excellent thank you. None of my PC are above 0.2CPU. The PC I write this on, Q6600 and ASUS 9800GTX, it is 0.02CPU. And far as I know I've never had to reboot just because of the 9800GTX, dead reliable.
