My motherboard is a MSI H55M-E23 (MS-7636) and I'm plannin to buy this RAM: Corsair Vengeance DDR3 PC3-12800 (1600MHz), 8 GB (2*4) can you please tell me if it is compatible with my mobo?
Only rarely will RAM not work with a motherboard and it's usually for less known manufacturers. It should work fine. I never use the compatibility lists for the motherboards on my builds.
