Server memory upgrade

This is an 8GB DDR3L ECC registered DIMM built for workstations, servers, NAS systems and routers. It runs at 1066MHz with CL7 latency and a 1.35V operating voltage. The module uses a 240-pin form factor and a 4Rx8 rank configuration. It is not compatible with standard desktop computers.

ECC registered design

Error-correcting code and registered buffering protect data integrity in multi-module server environments. JEDEC and RoHS compliance ensures the module meets industry specifications for reliable operation. The single 8GB stick allows capacity to be added one slot at a time. No heat spreader is fitted.

Compatibility check required

Verify that your system accepts DDR3L 1066 PC3L-8500 ECC registered memory in a 240-pin slot. The platform must support 1.35V modules and 4Rx8 density. This memory cannot be mixed with unbuffered or non-ECC DIMMs. Confirm the maximum supported capacity per slot before ordering.

Questions about this item

Will the 4Rx8 registered DIMM need a matching replacement if one rank fails?

The module is a single 8 GB 4Rx8 registered stick; if it fails the whole DIMM must be replaced with another DDR3L 1066 CL7 1.35 V ECC registered unit.

What limits sustained throughput on this PC3L-8500 CL7 kit?

The JEDEC-rated 1066 MT/s data rate and CL7 latency set the maximum bandwidth and response time under continuous load.

How much heat and power does the 1.35 V DDR3L module produce running all day?

At 1.35 V the DDR3L part draws less power and generates less heat than standard 1.5 V DDR3, and it has no heat spreader.
