Speed 5600MHz

  • 512 GB capacity in a 4 × 128 GB kit for maximum server density
  • DDR5 5600 speed rated at CL46 1.1 V for specified performance
  • Registered ECC RDIMM architecture corrects single-bit errors on the fly
  • 288-pin 2Rx4 form factor matches Supermicro H13SVW-NT slot requirements
  • Major OEM Samsung Micron Hynix chips validated for enterprise stability

Exact-match DDR5-5600 ECC RDIMM kit

This 512 GB kit contains four 128 GB modules that run at 5600 MT/s with CL46 timing at 1.1 V. The 288-pin Registered DIMMs use a 2Rx4 organisation and on-board ECC to meet the Supermicro H13SVW-NT memory controller requirements.

Suited for fully populated server slots

It fits administrators who need the board's maximum supported capacity with registered ECC stability. Builders using consumer UDIMMs, SODIMMs or non-ECC modules should look elsewhere because the platform requires registered DDR5.

Sustained-load behaviour

Registered buffering offloads the memory controller so every slot remains stable at full population and rated speed. ECC corrects single-bit errors continuously, preventing silent data corruption during extended workloads.

Questions about this item

What motherboard slot type must my Supermicro H13SVW-NT have to accept these 288-pin DDR5 RDIMM modules?

The board must provide 288-pin DDR5 RDIMM slots; UDIMM or SODIMM sockets will not fit this registered form factor.

Can I mix these 2Rx4 registered ECC DDR5 modules with older unbuffered DDR5 DIMMs in the same server?

No, registered and unbuffered DDR5 cannot operate together; the memory controller requires all populated slots to use the same registered architecture.

How can I verify the kit is running at the rated DDR5 5600 speed and CL46 latency after installation?

Check the BIOS memory information screen or run a hardware inventory tool; it should report DDR5 5600 (PC5-44800) with CAS latency 46 at 1.10 V.
