Server ECC Registered RDIMM

This OWC module is an 8GB DDR3 1333 PC3-10600 CL9 ECC Registered RDIMM built for workstations and servers. It operates at 1.5V with a 2Rx4 rank configuration on a 240-pin interface. The part number 1R3D32R408GB matches Lenovo part numbers 0A89412, 46C0542, 46C7449, 46U3419 and 49Y1436 for direct replacement.

Build Integration Requirements

The module requires a platform that supports DDR3 ECC Registered memory and cannot be used in standard desktop computers. It must not be mixed with unbuffered DIMMs in the same system. JEDEC and ROHS compliance ensures a warranty-safe upgrade for compatible server or workstation motherboards.

Sustained Load Behaviour

Every module is tested in-house to meet or exceed OEM specifications for long-term reliability. ECC functionality detects and corrects single-bit errors during continuous operation, maintaining data integrity under sustained workloads. OWC recommends populating all slots with identical capacity, speed and manufacturer modules for optimal stability.

商品問答

What is the maximum sustained speed this 1333 MHz DDR3 module can maintain under continuous server workloads?

The module is rated for DDR3 1333 (PC3-10600) operation at CL9 latency with 1.5V voltage, maintaining JEDEC-standard performance during extended use.

How much heat does this registered ECC DIMM generate when running 24/7 without a heat spreader?

As a 1.5V DDR3 1333 registered module without a heat spreader, it operates within standard JEDEC thermal limits for server environments with adequate airflow.

Which server motherboard slot and chipset combination is required for this 240-pin 2Rx4 registered memory to function?

This 240-pin DDR3 ECC registered RDIMM requires a server or workstation motherboard with registered memory support and cannot be used in standard desktop systems.
