Hardware Reference Guide 2–7

Hardware Upgrades

■

Install DIMMs in pairs across both memory channels. Each

DIMM socket populated with a DIMM on Channel A must be

populated with an identical DIMM on Channel B. For examples

of the correct configuration sequence, see the “DIMM Installation

Configurations” section later in this chapter.

■

Do not mix DIMMs with different memory speeds. Performance

will reflect the slowest speed DIMM.

■

Use only DIMMs that have been tested and approved by HP. Not

all DIMMs meet the HP standard for quality and reliability.

CAUTION: Your workstation will not function if the previous guidelines

are not followed when installing DIMMs.

DIMM Installation Configurations

When installing DIMMs, you must use the configurations in the

following table.

Identical pairs for dual channel operation means XMM1 and XMM2

must have the same type of DIMM and XMM3 and XMM4 must have

the same type of DIMM for a fully populated system.

If you are only putting in two modules then they must be the same and

go in either XMM1 and XMM2 or XMM3 and XMM4. You must

have one in each channel for dual channel operation.
