Sorry for not replying to the earlier suggestion, i missed the mail because i was being bombarded by mails. I did as you suggested and it did not work. In the meantime a bigger problem has arisen: During the tests i most have done something because now 48GB is not working either. I have not done anything to the OS but i have been resetting the CMOS every time i changed the RAM DIMMS. PS. I have unsubscribed from the main list and am only getting the digest, so everyone: When replying please CC to my mail also, otherwise You will have to wait till i get Your answer/question via the digest.
