Note 2: MIxing of 1.35V and 1.5V DIMMs is not recommended.
Note 1: Due to OS limitations, some operating systems may not show more than 4 GB of memory.
Note 2: Due to memory allocation to system devices, the amount of memory that remains available for operational use will be reduced when 4 GB of RAM is used. The reduction in memory availability is dispropor- tional. (See the following Table.)
