Hello Leann, Sorry for the delay. I just fix my problem with changing 2 memory slot from Kingston to the same which come with Dell.
When I did the memtest, I got no errors. Here's the new info about the memory: *-bank:0 description: DIMM DDR Synchronous 667 MHz (1.5 ns) product: HYMP512U72CP8-Y5 vendor: AD00000000000000 physical id: 0 serial: 00003169 slot: DIMM_1 size: 1GiB width: 64 bits clock: 667MHz (1.5ns) *-bank:1 description: DIMM DDR Synchronous 667 MHz (1.5 ns) product: HYMP512U72CP8-Y5 vendor: AD00000000000000 physical id: 1 serial: 00002113 slot: DIMM_3 size: 1GiB width: 64 bits clock: 667MHz (1.5ns) *-bank:2 description: DIMM DDR Synchronous 667 MHz (1.5 ns) product: HYMP512U72CP8-Y5 vendor: AD00000000000000 physical id: 2 serial: 04004166 slot: DIMM_2 size: 1GiB width: 64 bits clock: 667MHz (1.5ns) *-bank:3 description: DIMM DDR Synchronous 667 MHz (1.5 ns) product: HYMP512U72CP8-Y5 vendor: AD00000000000000 physical id: 3 serial: 00003114 slot: DIMM_4 size: 1GiB width: 64 bits clock: 667MHz (1.5ns) -- dmesg error with: EDAC MC0: CE page https://bugs.launchpad.net/bugs/291632 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
