128GB DDR3L ECC RDIMM Kit

This kit provides 128GB of DDR3L 1600 memory across four 32GB registered DIMMs. It is built for Dell PowerEdge M420, M520, M620, M820 and M915 servers that require ECC registered modules. The 1.35V DDR3L specification reduces power draw compared to standard DDR3. It suits administrators upgrading blade or rack servers in virtualisation or database roles.

Replaces Unbuffered or Lower-Capacity DIMMs

The upgrade moves a system from unbuffered memory to registered ECC modules, which the target platforms require for stability. It is worth the change when the chassis supports 4Rx4 registered DIMMs and the workload needs error correction at 1600 MT/s. The kit will not work in standard desktop boards that only accept unbuffered memory. It also cannot be mixed with existing unbuffered sticks in the same server.

Four-Module Server Configuration

The 240-pin form factor fits the memory slots of the listed PowerEdge models without adapters. Populating four slots with matched 32GB modules leaves remaining banks free for further expansion if the platform allows. The 1.35V operation helps thermal headroom in dense blade enclosures. JEDEC and RoHS compliance ensures the modules meet the server vendor’s electrical and environmental requirements.

Questions about this item

Does the 240-pin DDR3L RDIMM fit the Dell PowerEdge M620 blade server?

Yes, the 240-pin DDR3L 1600 RDIMM is listed as compatible with the Dell PowerEdge M620 as well as the M420, M520, M820 and M915.

What is the correct sequence for installing the four 32 GB modules?

Populate the lowest-numbered slot in each channel first, then add the second module to the matching slot in the same channel to keep the 4Rx4 ranks balanced.

When should the 1.35 V DDR3L ECC registered modules be replaced?

Replace them if the server logs correctable ECC errors that become uncorrectable, or when a memory diagnostic reports a persistent fault on any of the four DIMMs.
