Thanks Stefan, great suggestion, I failed to copy those configurations into my original message.

I am questioning my bus configurations... I haven't hooked up the scope yet, but I don't think data is hitting the bus. I don't see any areas to configure the I2C bus besides the board configuration file. Any suggestions?
Are you sure that 0x50 is correct? I suggest you try this instead:
#define SPD_EEPROM_ADDRESS { IIC0_DIMM0_ADDR, IIC0_DIMM1_ADDR }
Thanks, Stefan
