  • ECC protection prevents data corruption in critical workloads
  • Load Reduced architecture enables 512GB total capacity across 8 slots
  • 2933 MT/s speed supports high-throughput server applications
  • 20V operation matches standard DDR4 server power profiles
  • Validated for ASRock Rack EPYCD8-2T motherboard compatibility

System-Specific Server Memory Kit

This 512GB kit contains eight 64GB DDR4 LRDIMM modules built for the ASRock Rack EPYCD8-2T motherboard. It targets IT professionals who need maximum registered ECC capacity in a single qualified package.

DDR4 2933 Load-Reduced Limits

Load-reduced DIMMs reduce electrical load on the memory bus so all eight slots can be populated at 2933 MT/s, but the platform caps bandwidth at PC4-23400 and latency at CL21. Mixed-rank or higher-speed configurations are not supported by this qualified kit.

Eight-Module LRDIMM Installation

Populate all eight slots following the motherboard manual slot order; the modules have no heat spreaders, so airflow must come from chassis fans. Common issues include mismatched population rules and BIOS versions that do not recognise the full 512GB capacity.

I korthet

Frågor om den här produkten

Should I pick the 8x64GB kit or a different capacity for my ASRock Rack EPYCD8-2T?

This kit provides 512GB total across eight 64GB modules, matching the board's supported LRDIMM population rules for maximum capacity.

What does the 2933MHz rating deliver once installed in the EPYCD8-2T?

The modules run at DDR4 2933 (PC4-23400) with CL21 latency, giving the rated throughput when the platform memory controller operates at that speed.

How does the 288-pin DDR4 LRDIMM interface limit real-world performance?

The 288-pin DDR4 LRDIMM electrical interface caps transfer rate at 2933 MT/s and uses load-reduced buffering to maintain signal integrity across all eight slots.
