HP 413507-B21 512MB DDR2-667 Fully Buffered DIMM

This HP 413507-B21 module provides 512MB of DDR2 SDRAM operating at 667 MHz to the PC2-5300 standard. It uses a 240-pin fully buffered design intended for specific HP ProLiant server platforms. The part is supplied new and carries manufacturer part number 413507-B21.

Suits HP ProLiant ML350 G5.

This memory fits the HP Compaq ProLiant ML350 G5, ML350 G5 Base and ML350 G5 Entry servers listed in the compatibility data. It is not suitable for systems that require unbuffered or registered DDR2 modules, nor for platforms limited to lower density DIMMs. Buyers needing higher capacity per slot or a different DDR generation should verify their motherboard requirements before ordering.

512MB capacity with DDR2-667 headroom

The single 512MB module adds modest capacity for legacy server workloads running within the DDR2-667/PC2-5300 bandwidth envelope. Performance scales with the number of populated slots up to the platform maximum. Systems requiring larger memory footprints per DIMM or faster memory standards will exceed what this module can deliver.

Questions about this item

What server model must I have to install this 413507-B21 module?

This module is validated for the HP Compaq ProLiant ML350 G5, ML350 G5 Base and ML350 G5 Entry servers.

Will this 512MB DDR2-667 stick run with other PC2-5300 modules already in my ML350 G5?

Yes, it uses the same DDR2-667/PC2-5300 fully-buffered standard, so it will operate alongside existing modules at the common speed.

How can I confirm the 667 MHz speed is recognised after fitting the 240-pin DIMM?

Check the BIOS memory summary or the operating-system memory report; both should show the module running at 667 MHz.
