8 GB DDR3-1333 ECC Registered RDIMM

This OWC module provides 8 GB of DDR3 memory at 1333 MHz with CL9 latency and 1.5 V operation. It uses a 240-pin registered design with ECC and a 2Rx4 rank configuration. The part is fully JEDEC and ROHS compliant and matches Dell part numbers A4051416, A4051431, A4105734, A4188260 and A4188265.

For servers and workstations needing registered

Suitable for systems that require registered ECC DDR3 DIMMs and can accept 2Rx4 modules. It will not work in standard desktop computers that use unbuffered non-ECC memory. Buyers needing unbuffered DIMMs or a different voltage should look elsewhere.

Registered ECC with 2Rx4 organisation

The module is registered and ECC-enabled with a 2Rx4 rank layout. This specification determines compatibility with the target server or workstation platform. Verify that your system supports registered ECC DDR3 and the 2Rx4 organisation before purchase.

Questions about this item

How do I install this 240-pin DDR3 ECC Registered RDIMM and what is the common mistake?

Align the module key notch with the slot key, press straight down until both retention clips click. The common mistake is forcing an unbuffered DIMM into a registered slot or mixing registered and unbuffered modules, which prevents boot.

What maintenance or replacement will this 8GB DDR3 1333 CL9 module need later?

No routine maintenance is required. Replace the module only if memory diagnostics report correctable ECC errors that become uncorrectable, or if a DIMM fails POST testing after a firmware update.

What limit appears first when this 1.5V 2Rx4 RDIMM runs sustained workloads?

The 1333 MT/s data rate and CL9 latency set the throughput ceiling; sustained heavy loads will saturate bandwidth before the 1.5V supply or thermal limits become a factor.
