16GB DDR2-667 Fully Buffered ECC Kit

This 16 GB kit contains four 4 GB DDR2-667 fully buffered ECC DIMMs built for HP ProLiant XW6400, XW6600, XW8400 and XW8600 workstations. The modules run at 1.8 V with CL5 5-5-5 timings and use a 240-pin form factor. They are designed for server and workstation boards that require registered memory.

Who This Suits and Who It Does Not

It suits administrators upgrading or repairing the listed ProLiant models with matched, fully buffered ECC memory. It does not suit builders using desktop boards that accept only unbuffered non-ECC DDR2, nor systems limited to lower densities or different pin layouts.

Deciding Specification: Fully Buffered DDR2-667 ECC

The defining attribute is the fully buffered DDR2-667 ECC interface; the motherboard must explicitly support FB-DIMM technology at this speed. Without that support the modules will not function, so verify the platform requirement before ordering.

Questions about this item

What DDR2 standard does this PC2 5300 kit run at, and what speed does it cap at?

The kit runs at the DDR2 667 standard, which caps the data rate at 667 MHz.

What physical slot and pin count do the four 4 GB modules need?

Each module is a 240-pin fully buffered DIMM, so the system must provide 240-pin DDR2 slots.

How are the sticks installed in the HP ProLiant XW6400, XW6600, XW8400 or XW8600, and what step is often missed?

Power off the workstation, open the chassis, align the notch on each 240-pin module with the slot key, press firmly until the retention clips lock, then populate all four slots in the order shown in the system service guide to enable quad-channel operation.
