First off I have been researching this for a while with no success but I think I may have come close to the problem, for a few weeks ive noticed my os thinks I only have 6 gigs of ram installed and for some reason reserves 2050 mb for hardware, this is not correct I have 8 infact and hardware reserve should not exceed like 20mb, after little to no help from gigabyte tech with my ga-990fxa-ud3 rev1.1 f9, I did my own investigating finally just recently finding this article, http://benchmarkreviews.com/index.php?option=com_content&task=view&id=541&Itemid=38&limitstart=2 which seems to be pretty much exactly my problem, now why this is more likely is because when I think back to when I installed my H100 I pulled slightly to hard on my cpu cooler and pulled the cpu right out of the socket without releasing the lever, now I inspected it and nothing looked bent but im am uncertain now, is it a possibility I destroyed the cpu socket when that happened?
