Any errors related to memory in the output of dmesg?

Hi I have attached the dmesg.txt file. Could you please review?

Resolved: All i have to do is to remove and install the RAM again. Thanks for helping out.

Hi,
I duly note you re-seated the DIMMs to resolve this but how did you figure out it was a DIMM connection issue? I got half the RAM my system has but only one DIMM, so it is hardly just a matter of reseating the DIMM, which I did to note any physical damage. Nothing found.
If you any thing else I could check, this would be appreciated.
After verification, it was the built-in GPU VRAM setting set to the "half" of the RAM. All fixed! Hope this will help someone out too! =)
