Crashes after upgrade RAM

[TyShkan2]

After installation of two Kingston KVR800D2N5/2G my system start crashing. I noticed that it happens when free memory becoming equal 1.5Gb.
When removing one of them the system works fine.

Vista is working good. Gentoo's memtest found no errors.

Do you have any idea?

Is your total memory installed 2GB, like your signature says, or did you add an additional 2GB?

Crashes when total 4gb installed. Signature is old memory config, from which i'm upgrading (:

I found link to fix in your signature and trying it now.

If Slashack's fix (http://forum.insanelymac.com/index.php?showtopic=127611) doesn't work it doesn't work you can limit your memory with the boot-flag maxmem.
