HP 16GB DDR3 1600 Registered ECC Memory

This 16GB DDR3 module runs at 1600 MT/s with CL11 latency. It is built as a 2Rx4 registered DIMM with ECC for data integrity. The kit targets HPE ProLiant SL250s Gen8 base 2U left and right tray servers.

Thermals Noise and Power in Normal Use

Registered DDR3 DIMMs draw modest power and run within standard JEDEC voltage limits. Error-correcting logic adds negligible heat during typical server workloads. No active cooling is required beyond normal chassis airflow.

What This Replaces or Upgrades From

The module replaces lower-capacity or non-ECC DDR3 DIMMs in compatible SL250s Gen8 trays. The jump is worth it when workloads demand maximum registered capacity per slot and ECC protection. It is not for systems that require unbuffered memory or a different DDR generation.

Perguntas sobre este artigo

How do I install the 240-Pin DDR3 module in the ProLiant SL250s Gen8 tray server, and what step is often missed?

Align the notch on the 240-Pin DDR3 module with the slot key, press firmly until both retention clips click, then verify the registered ECC module is recognised in the BIOS memory map.

What maintenance or replacement will the 16GB registered ECC kit need later?

The 16GB DDR3 1600 CL11 module has no moving parts; replacement is only required if a memory error appears in the system event log or a capacity upgrade is planned.

What limit appears first when the 2Rx4 registered memory runs under sustained load?

The CL11 latency at DDR3 1600 (PC3 12800) sets the timing ceiling; sustained throughput cannot exceed the rated 12800 MB/s per module.
