Compatible Server Memory Upgrade

This 16GB DDR3L module operates at 1066MHz with a CL3 latency and runs at 1.35V. It uses a registered DIMM design with ECC error correction and a 4Rx4 rank configuration on a 240-pin form factor. The module is built as a direct replacement for IBM-Lenovo part numbers 47J0178 and 90Y3223. Quality assurance testing ensures reliable operation in supported server and workstation platforms.

Suited For Verified Platforms

This memory suits administrators upgrading or repairing IBM-Lenovo systems that specifically require DDR3L 1066MHz ECC registered modules. Builders needing unbuffered memory, non-ECC configurations, different speeds, or other DDR generations should not use this part. Compatibility depends entirely on the host system's qualified vendor list and memory specifications. Always verify supported memory details before purchasing.

Registered ECC With 4Rx4 Organization

The single decisive specification is the 4Rx4 registered ECC architecture combined with DDR3L 1.35V voltage. This rank structure and buffering type must match the motherboard's memory controller requirements exactly. Systems expecting a different rank count, unbuffered design, or standard 1.5V DDR3 will not support this module correctly.

商品問答

Will my server motherboard need 240-pin DDR3L slots and registered-DIMM support to use this 16 GB module?

Yes, the module is a 240-pin DDR3L 1066 MHz ECC registered DIMM that requires a motherboard with registered-DIMM capability and low-voltage DDR3 slots.

Can I mix this 4Rx4 1.35 V stick with existing 1.5 V DDR3 RDIMMs in the same system?

Mixing 1.35 V DDR3L with 1.5 V DDR3 is not recommended; the system will typically run all modules at the higher voltage, negating the low-voltage benefit and risking instability.

How do I confirm the module is running at 1066 MHz with ECC active after installation?

Check the BIOS memory information or OS tools such as dmidecode to verify the reported speed is 1066 MHz, the type shows DDR3L ECC registered, and the voltage reads 1.35 V.
