OWC 8GB DDR3L 1600 ECC RDIMM

This OWC memory module is an 8GB DDR3L 1600 PC3L-12800 CL11 registered DIMM built for Dell PowerEdge R520, R620, R715, R720 and R720xd servers. It operates at 1.35V with ECC and a 1Rx4 rank configuration on a 240-pin form factor. The module replaces Dell part numbers A7134886, A7545680, RKR5J and SNPRKR5JC/8G.

Who this suits and who should look elsewhere

The module fits administrators upgrading or repairing the listed PowerEdge platforms where registered ECC DDR3L memory is required. Buyers who need unbuffered memory for a desktop or workstation cannot use this part. Systems that demand a different voltage, pin count or rank organisation will not accept it.

Deciding specification — registered ECC DDR3L

The single specification that decides compatibility is the registered ECC DDR3L type at 1.35V. Only platforms designed for registered DDR3L ECC modules can use this memory; any system requiring unbuffered or non-ECC DDR3L will not work with it.

Questions about this item

Will this DDR3L 1600 ECC Registered RDIMM run alongside existing DDR3L modules in my PowerEdge R720?

Yes, it works in Dell PowerEdge R520, R620, R715, R720 and R720xd servers. All modules must be ECC Registered; mixing with unbuffered memory is not supported.

How can I confirm the module is operating at CL11 1.35V after installation?

Enter the system BIOS or iDRAC interface; the memory information screen will show 1600 MHz speed, CL11 latency and 1.35 V voltage for each installed DIMM.

Does the package include only the 240-pin RDIMM or are any extra parts required?

The box contains a single 8GB 240-pin DDR3L ECC Registered RDIMM. No additional cables, brackets or heat spreaders are needed or supplied.
