Server memory upgrade

This 8GB DDR3L RDIMM is built for Dell PowerEdge M610, M610X, M710 and M710HD servers. It delivers ECC registered operation at 1600MHz for workloads that require error correction and signal integrity. The module replaces Dell part numbers A7134886, A7545680, RKR5J and SNPRKR5JC/8G. It is not compatible with standard desktop computers.

Registered 240-pin form factor

The 240-pin DDR3L design fits server DIMM slots that accept registered modules. ECC registered buffering reduces electrical load on the memory controller, allowing higher capacities per channel. No heat spreader is fitted, so airflow in dense blade chassis remains unimpeded. This module cannot be mixed with unbuffered memory in the same system.

1.35V DDR3L at CL11

Operating at 1.35V, this PC3L-12800 module runs at CAS latency 11 with a 1Rx4 organisation. The lower voltage reduces power draw compared to standard DDR3 while maintaining 1600MHz throughput. Buyers needing higher density per slot or unbuffered ECC for workstation boards should look elsewhere.

Questions about this item

Does the PC3L-12800 DDR3L 1600 interface cap at 1600 MHz in these Dell PowerEdge servers?

Yes, the module runs at DDR3L 1600 (PC3L-12800) CL11, which is the rated speed for the M610, M610X, M710 and M710HD platforms.

Will the 240-pin 1.35 V registered DIMM fit the memory slots in a Dell PowerEdge M710HD blade?

The M710HD uses standard 240-pin DDR3L RDIMM slots, so this 1.35 V registered module seats directly without an adapter.

What is the correct way to install this 1Rx4 ECC registered DIMM, and which step do people often miss?

Power down the server, open the chassis, align the notch on the 240-pin module with the slot key, press firmly until both ejector clips lock, then verify in BIOS that ECC registered mode is enabled.
