I recently changed my motherboard to an Asus M4A89GTD PRO/USB3 that was given to me. It's a few years old, so most of the QVL ram isn't readily available anymore or really expensive for some reason. I purchased some Crucial Ballistix BLS2KIT 4G3D1609DS memory. It's a matched set of 2X4GB. Ever since installation I've had countless blue screen errors and boot issues. Is it possible this memory simply won't work with this motherboard. Or might I just need to tweak things. I've already tried so many different things. Form bios changes, to changing slot. Nothing seems to make a difference. I'm running Windows 7 64bit. The memory is recognized by the system. Although, sometimes it recognizes all 8GB and sometimes only 4GB. I've also run memchk that comes back clean. Any suggestions? I'm sure I've forgotten to mention something...
