All the other five boxes with Corsair ram work > fine. Is this the only box with 8Gb RAM? Do the others have smaller amounts? Is the motherboard and BIOS the same? Are you running the same kernel? Is the machine stable if you run it with mem=1024M on the kernel options line (so limitting it to 1Gb RAM). Do you need the hugemem kernel? -- rgds Stephen
