I remember you, thanks for all your info. So these are compatible, great I was second guess myself because on MSI web site does not list G-Skill as compatible memory.
Their compatibility list is the memory that they went through and hand tested to make sure they work properly straight out of the box. Often times they dont update that list as more products come out. As long as the board is an AM3 socket which it appears to be from the name, any DDR3 ram will work, the list is just the brands they promise will work.
For any ram you are considering, do your own homework.
Go to the ram vendor's web site, and access their configurator.
Corsair, Kingston, Patriot, OCZ and others have them.
Their compatibility list is more current than the motherboard vendor's QVL lists which rarely get updated.
Enter your mobo or PC, and get a list of compatible ram sticks.
Thanks, I went to G-Skills configurator & they do not show my MoBo listed. Does this mean I have the wrong ram or they do not list all compatible mobo?
