8GB DDR3 1333 ECC RDIMM

This 8GB registered DIMM runs at 1333 MHz with CL9 timing and 1.5 V standard voltage. It uses a 4Rx8 organisation and carries ECC for data integrity in server and workstation platforms. The module fits 240-pin DDR3 slots and is built as a compatible replacement for Kingston KVR1333D3LQ8R9S/8GEC and KVR1333D3Q8R9S/8G.

Thermals and power

Standard 1.5 V DDR3 voltage keeps power draw modest under typical server loads. Registered buffering reduces electrical load on the memory controller, helping maintain stable operation in multi-DIMM configurations. No active cooling is required beyond normal chassis airflow.

Upgrade context

This module replaces a failed or missing Kingston 8GB DDR3 1333 ECC RDIMM in qualified systems. The jump is worthwhile when expanding capacity on a platform that supports 4Rx8 registered memory and needs ECC protection for critical workloads. Buyers who need higher speeds, lower voltages, or unbuffered DIMMs should verify their platform specifications before ordering.

Questions about this item

How do I install the 240-pin DDR3 RDIMM and what step is often missed?

Align the notch on the module with the key in the 240-pin slot, press firmly until both side clips click, then verify in BIOS that the 1.50V ECC registered module is recognised at 1333 MHz.

What maintenance or replacement will this 8GB 4Rx8 module need later?

No routine maintenance is required; replace the module only if memory diagnostics report uncorrectable ECC errors or the system fails to POST with it installed.

What limit appears first under sustained load with this CL9 1.5V registered DIMM?

The 1333 MHz DDR3 bus bandwidth and CL9 latency ceiling are reached before the 1.5V thermal envelope becomes a bottleneck.
