Computer keeps locking up... assistance

I keep having this issue where my computer keeps locking up when I analyse positions for a while. I believe this problem is caused because the engines are using 100 percent of the available computer memory.

Does anyone know a way around this? ie to have the computer use on ninety percent of its memory, so leaving 10 percent for other stuff.

It is the same with every engine?

With all the Rybka engines I have:

Dynamic
Human
and Rybka 3.

Yes.

Yes, I guess that you doesn't let your computer work a so long time with other engines :) Anyway, it is unlikely to come from Rybka. How much RAM do you use?

Hello Garvin, what's the size of your memory and engine's hash table? Normally, at 1 or 2 GB RAM 256 MB hash table is enough.

Other things you can do: Open the taskmanager and check the priority level of the Rybka process. The default value is normal.
What's the use of tablebases? Up to 5 or 6 Men? Notice that the 6 Men need extrem much memory.
Open the GUI options and click on the tablebase tab. What's the size of the cashe memory? The best value is 8MB.

Ram: 3.49GB and I have the hash at 16mb.

6 men tablebases, but still have plenty of room on the hard drive.

How do I open the gui options, I use fritz 10 or 12 as my gui.

Do a right click at the free space under the chessboard. A popup-menu appears.
Click at options. Now you can see several tabs. Two of them are Tablebases GUI and Tablebases Engine.
There you can enter up to 3 paths where your tablebases are located on disk and the size of the cache-memory. At the GUI-tab you have a checkbox to activate for loading the TB's at program start. Fritz 10 options have only one tab for tablebases.
For more details click the help-button.

Josef. Your post is interesting to me. when I do your procedure I do not see the option of gui tablebases. You have any answer ? I have had much trouble with 6 man tablebases and Rybka. all seems to be ok for last 2 weeks, but my engine only can get TB's thru the PV's no Gui lookup. Sure would like to fix this, if anyone has a suggestion

Wayne, the GUI-tab only exists in ChessProgramm12. All lower versions have only the 'Tablebases' tab.
