I set it too 1G to even avond the 4Gb limit. Board should have 16Gb of mem.... It now get all the way to mounting the USB stick... This what could be the problem now? subsystem ffffff parse_acpi_tables(0)... SRAT: Ignoring memory at addr 0x100000000 SRAT: Ignoring memory at addr 0x220000000 SRAT: No memory found for CPU 4 done. subsystem 1000000 vm_mem_init(0)... vm_mem_init:131 done. I have both tried 1Gb and 4Gb. Could be that one of the DIMMs is defect, not seated correctly, or in the wrong slot?? This would suggest that 4Gb is missing: real memory = 12884901888 (12288 MB) Physical memory chunk(s): 0x0000000000010000 - 0x0000000000099fff, 565248 bytes (138 pages) 0x0000000000100000 - 0x00000000001fffff, 1048576 bytes (256 pages) 0x0000000001200000 - 0x00000000da659fff, 3645218816 bytes (889946 pages) avail memory = 3618148352 (3450 MB) done.
