512GB DDR4 2933 ECC LRDIMM Kit

This 512GB kit contains eight 64GB DDR4 2933 ECC LRDIMM modules built for servers and workstations. The load-reduced design reduces electrical load on the memory bus so dense configurations remain stable. It targets administrators who need maximum capacity per channel for virtualization or large datasets. The modules run at standard 1.20V DDR4 voltage.

Check DDR4 LRDIMM 4Rx4 Support First

Verify that your platform accepts DDR4 ECC LRDIMM modules with a 4Rx4 quad-rank layout before ordering. Desktop and laptop systems cannot use this memory type. Consult the system manual for supported speeds, maximum capacity per slot and required population order across channels. The 288-pin form factor fits only DDR4 server DIMM sockets.

Sustained Load Stability With Major Brand Chips

Major brand chips and factory testing at CL21 2933 MHz provide consistent throughput during extended compute jobs. The load-reduced architecture keeps signal integrity high when all eight slots are populated. ECC corrects single-bit errors in real time to prevent data corruption under continuous heavy workloads.

商品問答

Does the 512GB kit ship as eight individual 64GB modules or as a single stick?

The kit contains eight separate 64GB LRDIMM modules, each a 288-pin DDR4 2933 ECC Load Reduced DIMM rated at 1.20V with CL21 latency.

Should I choose the 4Rx4 quad-rank version or a dual-rank alternative for my server?

The 4Rx4 quad-rank x4 organisation maximises density per slot; select it only if your platform's memory controller and BIOS explicitly support 4Rx4 LRDIMMs at 2933 MHz.

What does the 2933 MHz rating actually deliver once the modules are installed in a compatible server?

In a supported system the memory runs at DDR4 2933 (PC4-23400) with ECC error correction and load-reduced buffering, providing 512GB total capacity at standard 1.2V operation.
