> 4 dimm, max 16GB. Ar eis 2x8gb ar reikia 4x4gb?


Geriau 4x4GB ir dar ko gero reiketu ne Single Rank, o Dual Rank moduliu.

1.2.1 System Memory Support


• 1-Gb and 2-Gb DDR3 DRAM technologies are supported.
• Using 2-Gb device technologies, the largest memory capacity possible is 16 GB for
UDIMMs (assuming Dual Channel Mode with a four dual rank unbuffered DIMM
memory configuration)
