Hi OpenChess users,

I've noticied that when I'm analysing chess positions with my old laptop the kn/s raise to a good (and normal) number but suddenly, after some minutes, it descends slowly but without stop.
What's wrong?

Thanks in advance,

Aitor

PS: It happens with all the engines, and with one or two cores activated. I use only 512 Mb of RAM and I have 4GB. No applications are running during the analysis.
PS2:I don't know if is useful but it's a Intel Core Duo T7700 not overclocked Windows Vista x64.

Could it be overheating? It sounds like throttling (the speed of the computer is reduced to avoid damage by heat).

Yes, the temperature is really high when the engine is thinking more thant 10 min.

Thanks Ovyron!
