Targeted Server Upgrade

This 16GB DDR3 module is built for specific HP ProLiant servers including the BL465c G7, BL685c G7, DL165 G7, DL385 G7 and DL585 G7 families. It delivers ECC Registered reliability for mission-critical workloads where data integrity is essential.

Replacing Lower Capacity DIMMs

Upgrading from smaller registered modules lets these platforms reach higher total memory ceilings for virtualisation and database tasks. The jump is worth it when current capacity limits the number of concurrent virtual machines or the size of in-memory datasets.

16GB Registered Headroom

A single 16GB DIMM provides substantial capacity per slot for memory-hungry applications running on supported G7 systems. It runs out when the server's maximum DIMM count or total memory limit is reached, or when workloads demand speeds beyond DDR3 1600.

Questions about this item

Will the 240-Pin DDR3 1600 module fit the HP ProLiant BL465c G7 server?

Yes, the 16GB registered ECC DIMM is validated for the BL465c G7, DL165 G7, DL385 G7 and DL585 G7 families listed in the compatibility table.

What is the correct way to seat this registered ECC memory in the ProLiant slot?

Align the notch on the 240-pin edge connector with the key in the DDR3 slot, press straight down until both side latches click, then verify the module height clears the 157.5 mil thickness spec.

When should I plan to replace the 16GB DDR3 1600 ECC registered module?

Replace the module if the system logs correctable ECC errors that become uncorrectable, or when a memory diagnostic reports a hard failure on this specific DIMM.
