Server DDR3 ECC RDIMM kit

This A-Tech kit supplies 32 GB of DDR3 1600 ECC registered memory in a quad-channel set of four 8 GB modules. It is built for servers and workstations that require registered DIMMs with error-correcting code.

Verify DDR3 registered support

Your system must accept DDR3 RDIMM modules at 1.5 V with a 2Rx4 organisation and 240-pin DIMM slots. Desktop or laptop platforms cannot use registered memory, so confirm the motherboard or chassis documentation before ordering.

Fills four DIMM slots for quad-channel

The four modules populate a full quad-channel bank, delivering 32 GB of registered ECC capacity. This leaves any remaining slots free for further expansion while providing the registered buffering that multi-socket server boards expect.

Questions about this item

Does the kit include all four 8 GB modules or must any be purchased separately?

The package contains four 8 GB modules for a total of 32 GB, so nothing extra is required.

Should I choose the 2Rx4 dual-rank modules or a single-rank alternative?

The kit uses 2Rx4 dual-rank x4 organisation, which is the only rank option offered in this 32 GB quad-channel kit.

What does the DDR3 1600 PC3-12800 rating mean for actual server throughput?

It indicates a peak transfer rate of 12 800 MB/s at CL11 latency on a 240-pin registered DIMM running at 1.5 V.
