OWC 64GB DDR3L ECC RDIMM kit

This 64GB kit contains two 32GB DDR3L 1600 ECC registered DIMMs built for Dell PowerEdge R815, R820, T320, T420 and T620 servers. It targets administrators who need to expand memory capacity in those specific platforms without mixing buffered and unbuffered modules.

Capacity and headroom for virtualization

The 64GB total provides headroom for multiple virtual machines, large databases or heavy multitasking workloads on supported PowerEdge systems. Four-rank 4Rx4 organisation and CL11 latency set the performance envelope; workloads that exceed 64GB or demand higher frequencies will require a different platform.

Fits Dell PowerEdge 240-pin slots

Modules install directly into 240-pin DDR3L slots on the listed servers and operate at 1.35V. They are not compatible with standard desktop motherboards or unbuffered memory configurations. JEDEC and RoHS compliance ensures a warranty-safe upgrade for the supported Dell models.

Questions about this item

Will these 1.35V DDR3L 1600 ECC registered DIMMs run alongside existing 1.5V DDR3 modules in my PowerEdge R820?

No, the manufacturer states this registered ECC memory cannot be mixed with unbuffered modules and requires DDR3L voltage; mixing voltages or buffer types will prevent the server from posting.

How can I confirm the 64GB kit (2x32GB 4Rx4 CL11) is detected at full speed after installation?

Enter the system BIOS or iDRAC interface on the PowerEdge R815, R820, T320, T420 or T620; the memory configuration screen should show 64GB total, 1600 MT/s, ECC registered status and correct rank population per channel.

Does the OWC 1R6T34R4064P kit include any heat spreaders, tools or cables, or just the two 240-pin RDIMMs?

The upgrade kit contains only the two 32GB 240-pin DDR3L 1600 CL11 4Rx4 1.35V ECC registered RDIMMs; no heat spreaders, installation tools or additional cables are supplied.
