8 GB DDR3 ECC Registered module

This 8 GB DDR3 DIMM runs at 1600 MHz with a CL11 latency and 1.50 V operating voltage. It uses a 240-pin registered design with ECC for error correction in server environments. The single-rank x4 organisation suits compatible HP platforms. Condition is refurbished.

Thermals noise and power draw

DDR3 modules draw modest power at 1.50 V and produce little heat under normal server workloads. No active cooling is required on the module itself. Standard chassis airflow keeps temperatures within specification. Acoustic impact is negligible.

Sustained load behaviour

Registered buffering and ECC maintain data integrity during continuous operation. The CL11 timing delivers consistent latency for long-running tasks. Single-rank density avoids the command-rate penalties seen with multi-rank alternatives. Stability is preserved across extended duty cycles.

Questions sur cet article

How do I install the 240-pin DDR3 DIMM and what is the common mistake?

Align the notch on the module with the slot key, press straight down until the retention clips click, and ensure the registered module is seated in a slot that supports registered memory; the common mistake is mixing registered and unbuffered DIMMs in the same channel.

What maintenance or replacement will the 8GB DDR3 1600 module need later?

No scheduled maintenance is required; if a memory error occurs, run a memtest to isolate the faulty DIMM and replace that single 8GB module rather than the whole set.

What limit appears first under sustained load with this CL11 1.50V registered memory?

The thermal limit of the DDR3 chips typically appears first during prolonged heavy workloads, so adequate airflow across the 240-pin DIMM is essential to maintain stability at 1600MHz.
