High-density DDR4 server kit

This NEMIX RAM kit delivers 1.5TB across twelve 128GB registered DIMMs running at DDR4 2933 with CL21 timing. Each module uses a 4Rx4 organisation at 1.2V and includes ECC for data integrity. The 288-pin RDIMM form factor fits compatible server and workstation motherboards.

Suited for maximum-capacity builds

Administrators populating every slot in a 12-channel platform to reach 1.5TB will use this kit. Systems with fewer than twelve slots, or boards that do not support 4Rx4 registered modules, cannot use this configuration. Buyers needing lower voltages or non-ECC memory should choose a different product.

4Rx4 registered organisation decides fit

The quad-rank 4Rx4 layout determines whether the memory controller can address the full 128GB per module. Verify the platform qualification list for 4Rx4 RDIMM support before purchase.

Questions about this item

Does the 288-pin DDR4 RDIMM form factor fit my server's DIMM slots?

These are 288-pin DDR4 RDIMM modules; they install in standard DDR4 RDIMM slots that accept registered ECC memory.

What is the correct sequence for populating all 12 modules across the CPU channels?

Follow the motherboard manual for channel population order; registered ECC modules must be installed in the prescribed slots per CPU to enable quad-rank operation at 2933 MT/s.

How can I verify long-term reliability of the 4Rx4 ECC registered modules under sustained load?

Each module undergoes stress testing under load before shipment; ECC corrects single-bit errors and logs multi-bit events for proactive monitoring.
