Exact DDR5-6400 Registered ECC Module

This 128 GB DDR5 RDIMM runs at 6400 MHz (PC5-51200) with a CL52 latency and 1.1 V operating voltage. The 2Rx4 registered design adds a buffer that lets the memory controller drive every populated slot at full rated speed. It is built for Supermicro H13SRA-F and H13SRA-TF motherboards that require 288-pin registered ECC memory.

DDR5 RDIMM Population Rules Apply

Registered DDR5 modules still follow the motherboard's qualified-vendor list and slot-population order; exceeding the approved ranks per channel or mixing ranks can prevent the system from posting at 6400 MHz. The board's memory controller must also support 128 GB single-DIMM capacity, which varies by BIOS revision and CPU SKU. Always verify the manual before installing.

2Rx4 Rank Determines Full-Speed Operation

The dual-rank x4 organisation is the single specification that decides whether this module will run at its rated 6400 MHz when all slots are filled. A different rank or width would change the electrical load and could force the controller to downclock the memory bus.

Frågor om den här produkten

Should I pick the 128 GB 2Rx4 kit or look for a different capacity for my Supermicro H13SRA-F?

This kit is a single 128 GB 2Rx4 Registered ECC RDIMM. Check your motherboard manual for the maximum capacity per slot and the approved population order before deciding.

Will the DDR5-6400 CL52 rating actually run at 6400 MT/s in my H13SRA-TF?

The module is specified at 6400 MT/s (PC5-51200) with CL52 at 1.10 V. Your board must support DDR5-6400 and the 2Rx4 Registered layout to reach that speed; otherwise it will downclock to the highest common setting.

Does the 288-pin RDIMM interface limit how many modules I can install per channel?

The 288-pin Registered DDR5 RDIMM form factor is required by the H13SRA-F and H13SRA-TF. Each module presents a 2Rx4 load; total DIMMs per channel is governed by the motherboard's memory-controller limits, not the pin count itself.
