I heard that the DQ6 has problems with heatsinks that need a backing plate. From what I understand some backing plates can be modified to enable clearance with the HS on the bottom of the mobo. Apparently you should never remove the mobo HS. I looked on the ThermalRight site and saw in the photos on their installation page that the fins covered the first two ram slots. This was on a 939 board but still something to consider. If I was you I would direct my question to ThermalRight before I purchased the unit, it's the only prudent thing to do.
