Default Maxed out CPU usage when running Hiarcs 8

Why would the CPU usage always show 100% when playing against or analyzing
with H8? I have set the hashtables down to 65MB (so as to play blitz), but
it runs 100% all the time. The hard drive makes alot of noise during it's
usage-- soon as I close it, the HD quietens back down to normal. Strange.

For CPU usage - it's pretty normal... Fir HDD noise, well how much of RAM

do you
have? Maybe you must upgrade it? Generally, I think that is not necessary

to
give him so much hash in blitz... Probably 16, or even 8 MB's of RAM will

be
enough.


It's a Wintel P4 with 512 MB running XP Home... I'll try reducing the hash
tables some more... my system will lock up with that maxed out CPU usage and
the screen saver trying to kick in-- evidently, you can't put it in infinite
analysis and just walk away ( without turning off the screen saver first, I
guess).

Why should it show anything else?


Perhaps it shouldn't --- but with the screen saver activated and H8 in
infinite analysis mode, the PC will lock up-- seems like that shouldn't
happen.

Also, I would think you should be able to surf while H8 is analyzing-- I
remember Dan Heisman doing this while doing some instruction on ICC.

But, I could certainly be wrong on this! {:-)

Something is wrong, of course, it shouldn't lock up. Having a chessprogram
running will stress the system a lot, so it could be a heat problem.
Is there an adequate air-flow in the case ? Have you overclocked the
cpu ? If so, set the cpu-speed to default and try again.

Usually, it appears locked up, but if you press Ctrl-Alt-Del, you should be
able to click cancel and get back to your desktop. If you are running an
OpenGL screensaver and it locks up [for real], then you might want to look
at not using an OpenGL screen saver. Those things are CPU intensive and
compete for cycles. If your machine is locking up, you have one of three
likely problems. Overheating, bad memory or bad CPU.
