Capacity and purpose

This kit provides 64GB of DDR3L ECC Registered memory in four 16GB modules. It is built for Dell Precision workstations and servers that require registered DIMMs with error correction.

Compatibility check

Verify that your system is a Dell Precision R7610, T3600, T3610, T5600 or T5610 and that it accepts DDR3L 1600 PC3L-12800 CL11 2Rx4 registered modules. This memory will not work in standard desktop boards or alongside unbuffered DIMMs.

Build and daily use

Modules use a 240-pin form factor without heat spreaders and operate at 1.35V. The registered design adds a buffer that stabilises heavy multi-module loads in workstation and server environments.

Questions about this item

What does the kit include and is anything else needed for installation?

The kit contains four 16 GB DDR3L 1600 ECC registered RDIMM modules for a total of 64 GB. No extra parts are required; the modules fit directly into the 240-pin DIMM slots of the supported Dell Precision workstations.

How do I decide between this 64 GB kit and a smaller capacity for my Precision T5600?

Choose the 64 GB kit if your workloads — virtualisation, large datasets or heavy multitasking — need more than 32 GB. The T5600 supports up to 64 GB per processor, so this kit fills all four slots for maximum capacity.

What does the 1600 MHz rating mean once the memory is running in my R7610?

The modules operate at DDR3L 1600 (PC3L-12800) with CL11 latency at 1.35 V. The registered design adds one clock cycle of buffering, which the R7610's memory controller expects, delivering the rated throughput for ECC workloads.
