DRAM ECC error detected on the NB

  • 772

From the past couple of days I am getting this annoying message continuously. Could anyone please tell me what this means and what I should do to fix this? I am using Opensuse 12.1

  1. the error message means that an error in your RAM was detected but it was corrected because you are using error-correcting RAM. if you're getting it a lot, then you have bad memory.

    memtest won't detect it because the error is corrected before memtest reads that bad memory. if you want memtest to detect the error, you have to turn off ECC in your BIOS settings.
