Server-grade DDR3L ECC RDIMM
This 16 GB DDR3L registered DIMM operates at 1600 MHz with CL11 latency and 1.35 V. It is built for workstations, servers, NAS devices and routers that require ECC registered memory. The module will not work in standard desktop computers or alongside unbuffered DIMMs.
Sustained error-correcting throughput
ECC and registered signalling protect data integrity during continuous workloads such as virtualisation, database serving or network storage. The JEDEC-standard PC3L-12800 timing maintains stable bandwidth without the voltage headroom of higher-speed modules.
240-pin 2Rx4 registered form factor
The 240-pin 2Rx4 registered layout is the single specification that decides fitment. Systems needing unbuffered, non-ECC or different pin-count memory cannot use this module.

Questions about this item
How much heat or power draw should I expect from the 1.35V DDR3L module running continuously?
The module operates at 1.35V, lower than standard DDR3, reducing power consumption and heat output during all-day server workloads.
What existing hardware must my system already have for this 240-pin ECC Registered RDIMM to function?
Your motherboard must support DDR3L 1600 ECC Registered memory with 240-pin DIMM slots and a chipset that enables ECC and registered operation.
Can I add this 16GB 2Rx4 stick alongside the original Lenovo 0C19535 modules already in my server?
Yes, it matches the Lenovo 0C19535, 46W0671 and 46W0672 specifications exactly, so it can be mixed with those identical modules.
