Server ECC RDIMM Kit

This 128GB kit contains four 32GB DDR3L 1066 ECC registered DIMMs built for servers and workstations. The modules run at 1.35V and use a 4Rx4 quad-rank organisation. They are designed to expand memory capacity in compatible enterprise systems.

Verify DDR3L Registered Support

Your system must accept DDR3L 1066 ECC registered DIMMs with a 4Rx4 layout and 240-pin form factor. Desktop and laptop platforms cannot use these modules. Check the manual for supported speeds, voltages, rank limits and channel population rules before ordering.

Quad-Channel Matched Set

The four modules are packaged as a matched quad-channel kit so the memory controller can interleave across all channels. This arrangement helps maximise throughput for multi-threaded server workloads. No additional software or accessories are included.

Questions about this item

What comes in the box and do I need anything else to install it?

The box contains four 32 GB DDR3L ECC RDIMM modules for a total of 128 GB. No extra parts are required; install them into compatible 240-pin DDR3 server slots.

Should I choose this 128 GB quad-rank kit or a different capacity?

Choose this kit when your server or workstation supports quad-channel DDR3L 1066 registered memory and you need the maximum 128 GB capacity across four slots.

What does the 1066 MHz speed mean once the memory is running in my machine?

Each module runs at 1066 MT/s with CL7 latency at 1.35 V, delivering PC3L-8500 rated bandwidth in a quad-channel configuration.
