Note 1: 1333 MHz RDIMMs will run at 1066 MHz (BIOS automatic downgrading).
Note 2: 1333/1066 MHz RDIMMs will run at 800 MHz (BIOS automatic downgrading).
Note 3: MIxing of 1.35V and 1.5V DIMMs is not recommended.

Note 1: 1333 MHz for two DIMMs per channel is supported when Unbuf./ECC DIMMs are used.
Note 2: MIxing of 1.35V and 1.5V DIMMs is not recommended.
Notes: Due to OS limitations, some operating systems may not show more than 4 GB of memory. Due to memory allocation to system devices, memory remain- ing available for operational use will be reduced when 4 GB of RAM is used. The reduction in memory availability is disproportional. (Refer to the Memory Availability Table on the following page for details.)
