Message 31605 - Posted: 16 Mar 2010, 0:06:43 UTC

A few days ago my recent average credit dropped massively (by a couple thousand) and I am having trouble finding a solution. Other users still have high numbers, and many have surpassed me, so it seems to be individual to my computer. Strangely, the windows taskmanager displays that I am using 100% of my cpu though I'm sure I'm not due to my RAC change, and because RealTemp only shows me using about 66% of my cpu. I'm stumped.

The project I am on is Docking@home. I'm running Windows 7 on an Intel i7 920 clocked to 3.8ghz (don't worry, its stable, I've got a massive cooler on it and have been running it at 3.8-4.0ghz for months).

Please post project problems (credit and RAC is a project problem) at the project. In this case in the Docking forums.

Will do.

I don't think that its a Docking problem however, it appears to be a BOINC/Windows problem. Windows seems to be giving the wrong indication of cpu load to BOINC, and BOINC is limiting itself according. I proved this using Prime95, though the task manager still indicated 100% load, as it had while under load from BOINC, my cpu temps went up, and RealTemp indicated a full 100% load instead of a 66% load.

This leads me to hypothesize there is a BOINC/windows problem.

wrong indication of cpu load to BOINC

BOINC doesn't do any of the calculations for the projects. It's merely a managing program. Any calculations are done by the project science applications. So in most all cases, the CPU load for BOINC is zero (bar when you have too many tasks queued, or when BOINC is doing benchmarks).

You can also have a heat problem, with filthy (sorry ;)) fans and heat sinks. Then most BIOSes these days will clock the CPU down so it doesn't overheat.

I see what you mean about the processes, so likely a Docking problem I suppose.

Have explored the BIOS/dirty sinc possibility, pretty sure that's not it due to Prime95 being able to push past what Docking is crunching.
