Server ECC RDIMM upgrade

This OWC module is an 8 GB DDR3 1333 ECC Registered DIMM built for Lenovo workstations and servers. It replaces part numbers 49Y1446, 57Y4427, 67Y0017 and 67Y1464 with identical specifications. The 240-pin form factor and registered buffer ensure signal integrity in multi-module configurations.

Sustained error-corrected throughput

Registered buffering reduces electrical load on the memory controller so the module maintains CL9 timing across full DIMM populations. ECC circuitry detects and corrects single-bit errors during continuous operation without halting the system. JEDEC-standard 1.5 V operation keeps power draw predictable under long-running workloads.

Registered buffer requirement

This module will not function in systems that accept only unbuffered UDIMMs. Desktop motherboards and consumer laptops cannot use registered memory. Verify the platform explicitly supports DDR3 ECC RDIMM before purchase.

Questions about this item

How much power does the 1.5V DDR3 1333 module draw when the server runs continuously?

Each module operates at 1.5V. Total power depends on how many DIMMs are populated and the server's memory controller efficiency.

What must the motherboard provide to use this 240-pin ECC Registered RDIMM?

A 240-pin DDR3 slot that supports ECC Registered memory and the PC3-10600 speed grade.

Can this CL9 2Rx4 stick sit beside older DDR3 modules in the same server?

OWC recommends matching capacity, speed and manufacturer for optimal performance; mixing different ranks or timings may cause instability.
