    DZ77RE-75K memory error when I350-T2 NIC installed?


      I have a DZ77RE-75K desktop board with an i7-3770S CPU, running a matched set of (4) 8G DDR3-1600 DIMMs for 32 gigs of installed memory.  Everything has been great for the last year and a half.


      Yesterday, I received an i350-T2 NIC to expand available ports for VM testing, bridging, etc.  Installing the i350 into the secondary PCIe x16 slot, the system gave me a beep code of three beeps and a POST code of "32" - which is supposed to indicate a memory error.  I tested various combinations of PCIe ports, removing all cards from the system (which is only a video board and a multiport serial adapter) - installed the i350-T2 into the primary port as the ONLY PCIe card - and still the memory error.


      However, taking out two sticks of RAM and lowering the system to 16G allowed a successful boot.


      The system board is running the latest available BIOS.  No other problems with the memory since installation - no system hangs, nothing - it just doesn't seem to like having 32G installed with that NIC.


      Any ideas on what else to try?
