So I have recently made the switch to Kubuntu 12.10 on my new desktop. Basically I am building a monster workstation and I ran into issue running Fedora 18. Since I wanted Steam support too I decided not to try to move to an earlier Fedora version, but rather, I chose to give Ubuntu another try (its been years since I have run Ubuntu).
Anyway, I am building this hoss of a work station that has 12 Dimm slots, which I fully populated with 4GB dims. However when I booted my new monster, I found that I was 8GB short in the Memory department.
So, how do I figure out which two dimms are bad? I certainly dont want to have to pull all of them out and boot the machine and test each dimm one by one.
So this is where lshw comes to the rescue. Which I blogged about back in 2010 here.
Anyway. Here is how you find the empty slots.
# lshw -short -C memory
which output what you see below.
0/14 memory System Memory
/0/14/0 memory 4GiB DIMM DDR3 1066 MHz (0.9 ns)
/0/14/1 memory 4GiB DIMM DDR3 1066 MHz (0.9 ns)
/0/14/2 memory 4GiB DIMM DDR3 1066 MHz (0.9 ns)
/0/14/3 memory 4GiB DIMM DDR3 1066 MHz (0.9 ns)
/0/14/4 memory 4GiB DIMM DDR3 1066 MHz (0.9 ns)
/0/14/5 memory 4GiB DIMM DDR3 1066 MHz (0.9 ns)
/0/22 memory System Memory
/0/22/0 memory DIMM DDR3 [empty]
/0/22/1 memory DIMM DDR3 [empty]
/0/22/2 memory 4GiB DIMM DDR3 1066 MHz (0.9 ns)
/0/22/3 memory 4GiB DIMM DDR3 1066 MHz (0.9 ns)
/0/22/4 memory 4GiB DIMM DDR3 1066 MHz (0.9 ns)
/0/22/5 memory 4GiB DIMM DDR3 1066 MHz (0.9 ns)
Basically this is telling me that my first two dimms on CPU two are dead and are the ones that need to be replaced.
Now all I have to do is powerdown and pull and replace two dimms.. which will save my fingers from much discomfort.
