Server ECC RDIMM Upgrade

This OWC module provides 16GB of DDR3 ECC registered memory for specific HP ProLiant servers. It operates at 1333MHz with CL9 latency and 1.5V power. The 240-pin RDIMM uses a 2Rx4 organisation and has no heat spreader.

For ProLiant Servers Only

The module suits HP ProLiant DL585 G7, ML370 G6, SL160s G6 and SL160s G7 systems that require registered ECC DDR3. It will not work in standard desktops or workstations that use unbuffered memory, and it cannot be mixed with unbuffered DIMMs.

Simple DIMM Installation

Installation follows the server's standard DIMM slot procedure; align the notch and press until the latches click. The main risk is inserting the module into a system that expects unbuffered memory, which prevents boot and can damage the slot.

Questions about this item

Does this 240-pin DDR3 ECC RDIMM require a server motherboard that supports registered memory?

Yes, it is an ECC registered module built for workstations and servers and will not work in standard desktop boards that only accept unbuffered memory.

Can I add this 16 GB module alongside existing unbuffered DDR3 DIMMs in my HP ProLiant?

No, registered and unbuffered memory cannot be mixed; all installed DIMMs must be registered for the system to operate correctly.

How do I confirm the module is running at DDR3 1333 CL9 after installation?

Check the BIOS or a system information utility — it should report the memory operating at 1333 MT/s with CAS latency 9 and 1.5 V.
