For luciel, Hi, you have ddram on all dim's (1 gig) so the dim1 & dim3 give DUAL channel mode as ram drive, you are sure your ram is compatible with dual channel mode ? and if you use single channel mode, (only use dim1 & dim2) you are sure your dram is 100% compatible with Nforce chipset? the nforce chipset are realy sensible with the quality of ram, generic ram are not supported look by your manufacterer the list of compatible ram chips for this motherboard. incompatible ram chips give unexplicated errors.
sorry for bad english i am french.
