Product identity

This is a 4GB DDR3L registered ECC DIMM built for server and workstation platforms. It targets administrators who need to replace or expand memory in compatible HP systems using low-voltage modules.

Thermals noise power

The module operates at 1.35V, reducing power draw compared to standard DDR3 parts. Registered buffering and ECC circuitry add minimal heat under typical server workloads. No active cooling is required on the module itself.

Build fit

The 240-pin DIMM fits DDR3L slots that support registered ECC memory. It frees a single slot for a 4GB capacity increase. Buyers needing higher densities or non-ECC unbuffered memory should look elsewhere.

Questions about this item

How do I install this 240-pin DDR3L RDIMM and which orientation mistake should I avoid?

Align the notch on the module with the key in the slot, press straight down until both clips snap shut, and never force it backwards — the single notch only fits one way.

What maintenance or replacement will this ECC registered module need over time?

No routine maintenance is required; if a correctable error count rises or the module fails, replace the 4GB stick with an identical DDR3L 1333MHz 1Rx4 RDIMM.

What limit appears first when this 1.35V registered DIMM runs sustained workloads?

The 1333MHz data rate and CL9 latency set the throughput ceiling before voltage or thermal limits become a factor.
