Server Memory Upgrade Kit

This 32GB kit contains two 16GB DDR3 1333 ECC Registered RDIMM modules built to JEDEC and RoHS standards. It targets administrators who need to expand memory in HP ProLiant SL165s G7, SL170s G6, SL335s G7, SL390s G7 or WS460c G6 servers. The modules run at 1.5V with CL9 latency and a 2Rx4 rank configuration.

Replacing Unbuffered Or Smaller DIMMs

The upgrade replaces unbuffered memory that the listed servers cannot use, or lower-capacity registered DIMMs that limit total system memory. The jump is worth it when workloads such as virtualization or large databases exceed the current memory ceiling and the platform supports registered ECC modules.

Installation And Common Issues

Installation follows the standard 240-pin DIMM procedure: power down, open the chassis, align the notch, and press until the latches click. The most frequent problem is mixing these registered modules with unbuffered DIMMs, which prevents the system from posting. All slots must use identical registered ECC parts.

Questions about this item

Will the 240-pin DDR3 RDIMM modules fit the DIMM slots on my HP ProLiant SL335s G7?

Yes, each 16 GB module uses the standard 240-pin DDR3 RDIMM form factor that matches the registered DIMM slots on the SL335s G7 and the other listed ProLiant models.

What is the correct way to install the two 16 GB sticks, and what mistake should I avoid?

Power down the server, open the chassis, and seat each module firmly until the retention clips click; the common error is mixing these registered ECC DIMMs with unbuffered memory, which the platform does not support.

When will the ECC registered DIMMs need replacement or maintenance?

The modules have no moving parts and require no scheduled maintenance; they should only be replaced if a memory diagnostic reports correctable or uncorrectable ECC errors over time.
