Exact-match server kit

This 768GB kit contains sixteen 48GB DDR5 RDIMM modules rated at 6400 speed with CL52 latency and 1.1V operation. It is built for the Supermicro H14DSG-O-CPU motherboard where registered ECC memory is required for full capacity and data integrity.

Verify population rules

Confirm the motherboard manual for approved DIMM population order, maximum supported capacity per slot, and any BIOS version requirements before installation. The 288-pin RDIMM form factor must match the board's registered memory slots exactly.

Sustained enterprise stability

Registered architecture buffers the memory controller so all sixteen slots can run fully populated at rated speed without signal degradation. ECC corrects single-bit errors continuously, preventing silent data corruption during extended workloads.

Questions about this item

Does the 768GB kit arrive as 16 separate 48GB modules or do I need to buy anything else to reach the full capacity?

The package contains 16 modules of 48GB each, giving the full 768GB with no additional parts required.

My board has 16 DIMM slots — is this 16-module kit the right choice or should I look for a different capacity?

The kit provides exactly one 48GB RDIMM per slot, matching a fully populated 16-slot Supermicro H14DSG-O-CPU motherboard.

What does the CL52 rating mean for real-world latency on this DDR5-6400 registered ECC memory?

CL52 indicates 52 clock cycles at 6400 MT/s, the timing the board's memory controller expects for stable registered ECC operation.
