Heres the situation, i have a Asus P7p33d-E lx motherboard. im running windows 7 pro 64bit. i have always ran on 4 gigs of ram (2 sticks of 2) and have recently gotten into more 'intensive' gaming requiring more ram. After raising some money up by selling some games i bought 2 sticks of 4 gig coarsair ddr3 ram. i attempted to install it and boot up. only to find it will boot untill 'starting windows' then freeze and crash with the blue screen error 'irql not less or equal' however it will start/run fine with my origional 2 sticks in alone. i have already attempted to set the timing/voltage of the ram in the bios to no avail. The bios does however state that it has 8 gigs of ram, so my suspicion is its an issue with windows. any help is much appreciated.
