the memory is G.skill pc2-6400 4-4-3-5 (promos) and they are stable 8 hours in memtest.crashed both prime95 and OCCT after 4 or 5 hours.
i will try setting the SB NB lower and i'll update.
i'll try occt ram mode and putting the ram on 800 5-5-5-15 just to check.
Static read control is disabled. i'll post a pic later.
thanks for the help. good night.
