Notes . . .

1. If higher or lower speed DIMMs are selected than what is shown in the table for a given CPU, the DIMMs will be

clocked at the lowest common denominator of CPU clock and DIMM clock. For example:

Selecting lower-speed DIMMs: if you use an X5570 CPU (which can support up to 1333-MHz DIMMs) with 1066-MHz

DIMMs, the DIMMs will be clocked at the lower speed of 1066 MHz.

Selecting higher-speed DIMMs: If you use 1333-MHz DIMMs with an E5520 (which can support up to 1066-MHz DIMMs),

the DIMMS will be clocked at the lower speed of 1066 MHz.

Approved Configurations

(1) One-CPU Configuration

Choose any one CPU from

■

(2) Two-CPU Configuration

Choose two identical CPUs from any one of the rows of

■

Caveats

You must select either one CPU or two identical CPUs.

■

For optimal performance, select DIMMs with the highest clock speed for a given processor. If

■

you select DIMMs whose speeds are lower or higher than that shown in the tables,

suboptimal performance will result.
