Hi, Just bought a J3455-ITX with 2 x 2GB DDR3. After getting home and reading the manual, its states "2GB DRAM per module not supported". Does that mean I Cannot use the 2 X 2GB = 4GB DDR3?

IF so, why is it not allowed?!

Thanks

Per your advice, it doesn't work. The power led comes on but nothing is displayed on the hdmi or vga port.

Seems like I need to get a 4 gb module! :(
