OWC 8GB DDR3L 1600 ECC RDIMM

This module is an 8GB DDR3L 1600 CL11 registered DIMM with ECC. It operates at 1.35V and uses a 1Rx4 organisation on a 240-pin form factor. It is designed for Dell PowerEdge M420, M520, M620, M820 and M915 servers.

Verify registered ECC support and voltage

Confirm that your server accepts registered ECC DDR3L memory at 1.35V. This module cannot be mixed with unbuffered DIMMs and will not work in standard desktop platforms. Check the system manual for maximum capacity per slot and supported population rules before ordering.

Suited for compatible PowerEdge upgrades

Ideal for administrators extending the life of the listed Dell blade and rack servers with a matched 8GB registered ECC module. Not suitable for desktop PCs, laptops or any system that requires unbuffered or non-ECC memory. Builders needing different capacities, speeds or form factors should look elsewhere.
