Server Memory Kit

This A-Tech 64GB kit contains four 16GB DDR3 registered DIMMs built for servers and workstations. Each module runs at 1600 MHz with CL11 latency and ECC error correction. The dual-rank x4 organisation and 1.5V operation match standard DDR3 registered specifications.

Compatibility Check

Verify that your system accepts DDR3 registered ECC DIMMs in a 240-pin form factor before ordering. Desktop and laptop platforms cannot use these modules. Consult the motherboard manual for supported capacities per slot, quad-channel population rules and any rank or voltage limitations.

Sustained Load Behaviour

Registered buffering reduces electrical load on the memory controller during continuous operation. ECC circuitry corrects single-bit errors without halting the system, maintaining data integrity under heavy workloads. The 1.5V standard voltage keeps power draw predictable during extended compute tasks.

Questions about this item

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

The box contains four 16 GB DDR3 1600 MHz ECC RDIMM modules for a total of 64 GB. No extra parts are required; install them directly into 240-pin registered DIMM slots.

Why choose the 64 GB quad-channel kit instead of a smaller kit?

The 64 GB kit provides four matched 16 GB dual-rank modules that run at 1600 MHz CL11, filling all channels on compatible servers and workstations for maximum bandwidth.

What does the DDR3 1600 CL11 rating mean once the modules are installed?

Each module operates at 1600 MHz with CAS latency 11 at 1.5 V, delivering the rated PC3-12800 speed on supported DDR3 server and workstation platforms.
