Unganged Mode Causes Crashes

okay so i recently installed an additional 4 gigs of ram into my system (the exact same models as first 2). giving me 8 gigs total. everything was going fine until i got a bsod saying IRQ_NOT_LESS_OR_EQUAL]. long story short i go into my bios and adjust my ganged/unganged setting to ganged then everything works fine. i get the concept behind ganged and unganged and i would really prefer unganged over ganged. any ideas why choosing unganged mode triggers a BSOD and any ideas on how i would be able to run unganged mode without triggering a BSOD????


system specs:
Mobo: MSI 880GM-E43 AM3 AMD 880G HDMI Micro ATX AMD Motherboard

Ram: x2 CORSAIR XMS 4GB (2 x 2GB) 240-Pin DDR3 SDRAM DDR3 1333 Ultra Stable Desktop Memory Model CMX4GX3M2A1333C8

    This error is frequently caused by a bad, or incompatible driver installed in the system. Remove recently installed drivers, until you find the one that causes the system to stop.
    On my system, I have this error when I try to install a USB Ethernet driver. When I use a non USB internet connection, it does not occur.
  2. this happens even during A fresh windows install during setup so i dont think its a driver issue. I switch to ganged mode and everthing works perfectly but when i change to unganged mode constant BSOD's switch it back smooth running. is there something im supposed to be enabling or disabling with the unganged mode switch??


    Edit: i have also ran Memtests current ram setup with absolutely no errors.
