I disabled Fast Writes in modprobe.conf
options nvidia NVreg_EnableAGPSBA=1 NVreg_EnableAGPFW=0
And chdanged it to False in xorg.conf
Option "UseEvents" "False"
and now it seems to work stable, but performance is decreased. And i cant overclock that much my card, that i was able with previous drivers(500@644MHz GPU, 1400@1800MHz ).
I have Galaxy 7300GT with 128MB DDR3 AGP Zallman Edition.
