Speed DDR5 6400 (PC5 51200)

  • 128 GB total capacity from eight 16 GB modules
  • DDR5 6400 speed with CL32 latency for responsive workloads
  • ECC registered design detects and corrects data errors
  • 40 V operation with XMP 3.0 and EXPO profiles
  • Professional heat spreader keeps modules cool under load

Capacity and configuration

This kit delivers 128 GB across eight 16 GB registered DDR5 modules. It targets workstation and server builds that need high-density ECC memory for multi-threaded workloads and large datasets.

Speed, latency and voltage headroom

The modules run at DDR5 6400 with CL32 timings of 32-39-39-84 at 1.40 V. Intel XMP 3.0 and AMD EXPO profiles enable one-click overclocking, while the registered design and ECC maintain stability under sustained load.

Platform and interface limits

The 288-pin RDIMM form factor fits DDR5 server platforms such as AMD TRX50 and WRX90 or Intel W790 and W890 chipsets. ECC correction handles single-bit errors, but the registered buffer adds one cycle of latency compared with unbuffered DIMMs.

Questions about this item

Will the 8x16GB DDR5 6400 CL32 1.40V ECC RDIMM kit install alongside older DDR5 modules already in my server?

All slots must run at the same speed and voltage; mixing modules with different data rates or timings can prevent the system from posting.

How can I verify the 6400 MT/s speed and CL32-39-39-84 timings are active after installing the 128GB kit?

Enable the Intel XMP 3.0 or AMD EXPO profile in BIOS, then check the memory tab in CPU-Z or the firmware memory information screen for 6400 MT/s and the listed timings.

Does the 8-module box include any mounting brackets, cables or additional cooling parts, or must I buy them separately?

The package contains only the eight 288-pin RDIMM modules with integrated heat spreaders; no brackets, cables or extra cooling accessories are supplied.
