Rank 1Rx8

  • ECC registered design protects data integrity in servers
  • 64 GB total capacity across four 16 GB modules
  • DDR5 4800 speed with CL40 latency for responsive performance
  • 1 V operation reduces power draw in dense configs
  • JEDEC compliant and ROHS certified for broad compatibility

Server DDR5 ECC RDIMM kit

This 64GB kit contains four 16GB DDR5 4800 CL40 registered DIMMs built for compatible workstations and servers. Each module runs at 1.1V with a 1Rx8 organisation and ECC protection. The 288-pin form factor follows JEDEC PC5-38400 specifications.

Registered ECC cannot mix with unbuffered

Registered ECC memory will not operate in standard desktop platforms that expect unbuffered modules. It also cannot be combined with load-reduced ECC DIMMs in the same system. Buyers needing memory for consumer motherboards or mixed ECC types must choose a different product.

4800 MT/s JEDEC standard speed

The kit operates at the DDR5 4800 (PC5-38400) baseline with CL40 latency. Systems requiring higher factory-rated frequencies or lower latencies will not reach those targets with this module.

商品問答

Should I buy the 64GB kit or look for a different capacity?

This kit provides 64GB total across four 16GB modules, designed for dual-channel server platforms that support registered ECC DDR5.

What does the 4800 speed rating deliver in a live system?

The modules run at DDR5 4800 (PC5-38400) with CL40 latency at 1.1V, giving JEDEC-standard bandwidth for compatible workstations and servers.

Will the 288-pin registered ECC interface work in my motherboard?

These are 288-pin DDR5 RDIMMs with ECC and registered buffering; they require a server or workstation board that explicitly supports registered ECC DDR5 and cannot be used in standard desktop slots.
