Server memory kit for DDR3 platforms

This A-Tech kit supplies 128 GB across eight 16 GB DDR3 registered DIMMs. It is built for servers and workstations that require ECC RDIMM modules and will not function in desktop or laptop systems.

Registered ECC DDR3 1866 with 2Rx4 organisation

Each module runs at 1866 MHz (PC3-14900R) with CAS latency 13 at the standard 1.5 V. The dual-rank x4 layout and registered buffer are mandatory for the target platform's memory controller.

Eight-module capacity for high-density

The 128 GB total fills eight 240-pin slots, giving ample headroom for virtualisation and large datasets. Systems with fewer than eight slots or a lower per-slot limit cannot use the full kit.

Questions about this item

What does the 1866 MHz rating mean once the modules are installed in a server?

The 1866 MHz speed sets the maximum data rate the memory controller can use; actual throughput depends on the platform's supported DDR3 frequencies and the number of populated channels.

How does the PC3-14900 designation limit real-world bandwidth?

PC3-14900 indicates a peak transfer rate of 14900 MB/s per module; the registered buffer adds one cycle of latency, and total system bandwidth is capped by the memory controller's maximum supported DDR3 speed.

What physical slot and clearance do the 240-pin RDIMMs require?

Each 16 GB module uses a standard 240-pin DDR3 DIMM keying for registered memory; verify the server board has eight available RDIMM slots and sufficient height clearance for the heatspreader.
