8GB DDR3 ECC UDIMM for Servers

This 8GB DDR3 1333MHz PC3-10600 ECC UDIMM module provides error-correcting memory for compatible server and workstation systems. It operates at standard 1.5V voltage with CL9 latency and uses a 2Rx8 rank configuration. The unbuffered DIMM design fits 240-pin slots in platforms that support DDR3 ECC unbuffered memory.

Thermals and Power in Normal Use

Running at the standard DDR3 voltage of 1.50V, the module draws typical power for its capacity and speed during regular workloads. Error-correction overhead adds minimal thermal load compared to non-ECC equivalents. No active cooling is required on the module itself; standard chassis airflow is sufficient for stable operation.

Build Fit and Compatibility

The 240-pin DIMM form factor installs directly into DDR3 UDIMM slots on qualified server or workstation motherboards. It serves as a compatible replacement for HP part 500674-B21. Builders must confirm the platform supports DDR3 ECC unbuffered memory at 1333MHz before purchase. Systems requiring registered or load-reduced DIMMs cannot use this module.

Questions about this item

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

Align the notch on the module with the slot key, press straight down until both retention clips click, and verify the ejector tabs lock fully; the frequent error is seating only one side so the module appears in but the ECC circuitry does not initialise.

What maintenance or replacement will this ECC UDIMM need over its service life?

No scheduled maintenance is required; the module should run for the lifetime of the platform, and replacement is only necessary if a memory diagnostic reports uncorrectable errors or the system fails to POST with the DIMM installed.

What limit appears first when this 1.50 V DDR3 1333 MHz module runs sustained workloads?

The 1.50 V operating voltage and CL9 latency set the thermal and timing ceiling; under continuous load the DRAM temperature rises until the memory controller throttles bandwidth to stay within JEDEC thermal limits.
