  • SpeedDDR4 3200 (PC4 25600)
  • ECCYes
  • Buffered/RegisteredLoad Reduced
  • ChipsetMajor OEM Samsung, Micron, Hynix

Capacity 512GB 8X64GB

  • 512 GB total capacity from eight 64 GB modules for high-density server workloads
  • DDR4 3200 speed with PC4-25600 bandwidth keeps data flowing in multi-threaded tasks
  • ECC LRDIMM load-reduced design improves signal integrity on heavily populated memory channels
  • 4Rx4 organisation and CL22 latency balance throughput and response time for EPYC platforms
  • 2 V operation reduces power draw across all eight modules in 288-pin form factor

Capacity and form factor

This kit delivers 512GB of DDR4 memory across eight 64GB LRDIMM modules. Each module uses a 288-pin interface and operates at 1.2V with CL22 latency. It is built for servers and workstations that require high-density registered memory with error correction.

Sustained-load behaviour

Load Reduced architecture lowers electrical loading on the memory bus so all eight ranks per module remain stable during extended workloads. ECC circuitry detects and corrects single-bit errors without halting the system. The 3200 MT/s data rate and PC4-25600 bandwidth support continuous throughput in virtualization and database tasks.

Compatibility checks

Verify that your motherboard accepts 4Rx4 LRDIMM modules and supports the full 512GB capacity across eight slots. Confirm the platform runs DDR4 at 3200 MT/s with 1.2V operation and provides ECC functionality. Ensure the BIOS recognises the module part number ML25600-944K8 for proper training.

Questions sur cet article

How much heat does the 1.2V DDR4 3200 kit generate under continuous server load?

The modules run at 1.20 volts with no heat spreader, so they rely on chassis airflow to stay cool during all-day operation.

Does the ASRock Rack ROMED8-2T need any specific BIOS setting or firmware revision to recognise eight 64 GB LRDIMMs?

The kit is validated for the ROMED8-2T with AMD EPYC processors; consult the motherboard manual for the exact BIOS version and memory population rules.

Can I mix these 4Rx4 ECC LRDIMMs with older registered DIMMs already installed in the same board?

Mixing load-reduced and standard registered modules is not supported; all slots should use identical 4Rx4 LRDIMMs for stable operation.
