| It is running in dual channel mode. The POST used to report "Dual Channel Disabled" before I added the other 512MB. All the modules are DDR400 CL2.5, so I don't see any problem there. The dual channel mode will activate as long as I have 2 identical modules (or downgrade one to match the other) plugged in the DIMM1 and DIMM2, the 3rd DIMM just act as an extra bank of memory. |
