I have Deep Rybka 3 and I use it for analysis on my HP laptop . It's a Core 2 duo processor with 2.00 GZ speed. But each time I use the program the CPU becomes 100% busy and can lead my laptop to crash. Can I set up Rybka in a different way I don't want my laptop to overheat.

you can set it to use just 1 CPU, but of course, youll only get 1/2 speed. you can also change the priority of the engines (rybka loads 2) by hitting control+shift+escape & right clicking the rybka engines. set priority to below normal for them both; that might be enough to keep your system from crashing. rybka will still use as much CPU as possible but be relegated to secondary status whenever windows needs to use resources for other tasks. i know when i set rybka to use all CPUs but lower the priority everything else runs as if rybka wasnt even running in the background. hope that helps.

I have downloaded Rybka 3 single version with ChessOK downloader but I can't install. "Cannot create file 0.dll" is the message I get when trying.

you can edit deep rybka to use just one 1 cpu, no need for the single cpu version. what GUI are u using?

Mmh, try using "save ressource (manual installation)", maybe that works. However, you can set the cpu usage in your GUI, just set the parameter "Max CPU" to 1 . Which GUI are you using?

I use Aquarium how do I change the settings?

Got to "Engines" mode and click on the Rybka entry. You now see a lit of options in the window below the list. There you can set the parameter to 1 CPU and press enter.

So the original value is 2048 , I should put it to 1024 or even lower, right?
Parent - - By Felix Kling (Gold) Date 2009-10-05 11:10
To "1", if you want to use just one CPU. The standard value is extremely high just to be no limit.
Parent - - By jejega (**) Date 2009-10-05 11:13
Are we talking about the box "max CPUs" reset up to 1?
Parent - - By Felix Kling (Gold) Date 2009-10-05 11:15
yes, if you want to limit Rybka to a certain number of cores, you have to set the number there. Standard is 2048, but noone has that much cores of course :)

Set it to 1 and press enter, then Rybka uses just one core.

But that will waste his resources, I'd suggest setting all Rybka processes to low priority first.

I suspect your fan is clogged up with dust.  Open up your laptop, clean the fan from dust, and this will prevent yuor laptop from over-heating and shutting down.

I do this once every 6 months and it stopped my laptop from having the same problem as yours

Don't do this until you've looked at some websites about how to do it and make sure you earth yourself and stay clear of the circuit baord

I doubt that all laptops are designed for, or capable of, 100% cpu load for long time. I think he is safe with using only one core for engine analysis. The speed loss is not 50% but more like ~40%, only. Also, if one core runs the engine thread, "normal" applications on the other core like internet surfing or text processing will not cause heavy additional load.
