Server memory upgrade

This OWC module is an 8 GB DDR3 ECC registered DIMM built for workstations, servers, NAS systems and routers. It replaces the Supermicro MEM?DR380L?SL04?ER16 part number with identical specifications. The kit is JEDEC-standard and RoHS compliant.

Registered ECC requirement

The single deciding specification is the registered ECC design with a 1Rx4 rank layout at 1.5 V. This memory will not work in standard desktop computers and cannot be mixed with unbuffered modules. Buyers who need non-ECC or unregistered DIMMs must choose a different product.

240-pin DDR3 platform fit

The module plugs into a 240-pin DDR3 slot running at 1600 MHz (PC3-12800) with CL11 latency. It requires a platform that supports registered ECC DDR3 and frees you from sourcing the original Supermicro part. Systems without DDR3 registered ECC support cannot use this module.

Questions about this item

What does DDR3 1600 CL11 mean for actual server performance?

The module runs at 1600 MHz with a CAS latency of 11 cycles, delivering PC3-12800 bandwidth for registered ECC workloads.

What does the 240-pin DDR3 ECC registered interface limit in practice?

It fits only 240-pin DDR3 registered DIMM slots and cannot be mixed with unbuffered memory or used in standard desktop boards.

What physical clearance does the 1Rx4 240-pin RDIMM need?

The module uses a standard 240-pin DIMM height with no heat spreader, so it fits normal server DIMM sockets without extra vertical space.
