HP 16GB DDR3L 1333 ECC Registered Server Memory

This 16GB DDR3L module runs at 1333 MT/s with CL9 latency and 1.35V operation. It is built as 2Rx4 registered ECC memory for HPE ProLiant SL250s Gen8 left and right tray servers. The 240-pin form factor matches the platform's DIMM slots exactly.

Upgrade From Lower Capacity Or Non ECC Modules

The jump is worth it when virtualisation, large databases or high performance computing workloads demand greater capacity and error correction. HPE SmartMemory authentication unlocks extended performance features through the system ROM on Gen8 platforms. Systems without ECC support cannot use the registered buffer or error checking functions.

Installation Requires Matching Gen8 Server Tray

Insert the module into the correct DIMM slot for the left or right tray as specified by the server service guide. The registered design adds a clock cycle so the memory controller must support registered DIMMs. Mixing registered and unbuffered memory or using non HPE qualified modules will prevent the system from enabling SmartMemory features.

Pytania dotyczące tego produktu

Does the 240-pin DDR3L module fit the HPE ProLiant SL250s Gen8 left and right trays?

Yes, the 240-pin DDR3L 1333 registered DIMM is designed for the HPE ProLiant SL250s Gen8 Base 2U left and right tray servers.

How do I install the registered ECC memory and what step is often missed?

Power down the server, open the chassis, align the notch on the 240-pin module with the slot key, press firmly until the ejector tabs click, then enable HPE SmartMemory features in the system ROM.

Will the 1.35 V DDR3L 16 GB modules need replacement under heavy virtualization loads?

HPE SmartMemory qualification and ECC error correction are built for sustained virtualization and cloud workloads; no scheduled replacement is required beyond standard server lifecycle policies.
