Motherboard: MSI H57M-ED65
My motherboard does not recognise my 6GB DDR3 of ram whereas it does recognize the 4GB. I have 3 modules of 2GB each and in the specific bios features it does see the 3 slots and the time frequencies of the three of 'em.
tips: i have a windows 7 64bit system with the latest updated version of bios for my motherboard
