64GB DDR3 1600MHz ECC LRDIMM Module

This A-Tech module delivers 64GB of DDR3 1600MHz server memory in a single load-reduced DIMM. It operates at the standard 1.50V DDR3 voltage with CL11 latency and uses an 8Rx4 rank configuration built on Samsung chipset. The 240-pin form factor fits compatible DDR3 DIMM slots.

Server and workstation upgrades needing ECC LRDIMM

This module suits administrators expanding memory capacity in qualified DDR3 platforms that specifically support load-reduced ECC DIMMs. Builders whose systems require standard registered DIMMs or unbuffered memory cannot use this part. Systems limited to lower-density ranks or different voltage requirements should look elsewhere.

8Rx4 load-reduced rank decides fit

The 8Rx4 load-reduced organisation is the single specification that determines whether this module will function in a given server or workstation. Only platforms validated for DDR3 1600MHz ECC LRDIMM with this exact rank structure will recognise and stabilise the full 64GB capacity.

Questions about this item

How much power does the 64GB DDR3 1600MHz ECC LRDIMM draw at its rated 1.50V during sustained all-day server workloads?

The module operates at the standard DDR3 voltage of 1.50V. As a Load Reduced DIMM it reduces electrical load on the memory bus, helping to keep system power draw lower than a comparable standard registered DIMM at the same voltage.

What motherboard slot and chipset support are required to run this 240-pin DDR3 ECC LRDIMM?

The module uses a 240-pin DDR3 DIMM form factor and requires a server or workstation motherboard that supports DDR3 ECC Load Reduced memory. Verify your system's qualified vendor list for the Samsung M386B8G70DE0-CK0 or M386B8G70DE0-CK03 part numbers before purchase.

Will this CL11 8Rx4 LRDIMM work alongside existing DDR3 registered DIMMs in the same server?

Load Reduced DIMMs and standard Registered DIMMs use different buffering technologies and cannot be mixed in the same memory channel or, on most platforms, in the same system. Populate all slots with identical LRDIMMs for supported operation.
