Why the mismatched RAM count? 12GB was fine back in the LGA1366 days, but it requires an odd selection of DIMMs now. Yeah, it'll probably work, but why not bump it to 16GB to make things symmetrical?
G.Skill is top of their game lately as far as RAM if you want a vendor to go with (if it's not already chosen)
