Server memory for data-integrity workloads

This 64GB kit delivers two 32GB DDR5 RDIMMs rated at 6400 MT/s with CL32 32-39-39 timings. Registered buffering and on-die plus side-band ECC protect data accuracy in multi-socket servers and workstations. The 288-pin modules operate at 1.40V and include a register clock driver for signal stability. It suits administrators who need registered ECC capacity for virtualization or database tiers.

Thermals power and acoustics

A metal heat spreader covers each module to move heat away from the DRAM and the register clock driver. The onboard temperature sensor lets the platform monitor thermals and adjust fan curves without extra wiring. Power draw scales with the 1.40V operating voltage and the 6400 data rate under sustained load. No moving parts are present so the kit adds no audible noise of its own.

What the extras change

The 30µ gold-plated edge connectors resist oxidation over repeated insertions in dense server chassis. On-die ECC corrects single-bit errors inside the DRAM array while side-band ECC extends protection across the command bus. The register clock driver re-times control signals to maintain timing margin at 6400 MT/s. Together these features reduce correctable-error interrupts and help the platform sustain uptime.

Questions about this item

How do I install the 288-pin DDR5 RDIMM modules and what step is often missed?

Align the key notch on each 288-pin DDR5 RDIMM with the slot, press down firmly until both side clips click, and ensure the register clock driver engages for stable performance.

What maintenance or replacement will the 64GB dual-channel kit need over time?

The 30µ gold-plated connectors resist oxidation, while the on-die ECC and side-band ECC handle error correction; no user-serviceable parts require scheduled replacement.

What limit appears first when the 1.40V modules run sustained workloads at 6400 MT/s?

The temperature sensor protection triggers throttling before voltage or timing limits are reached, preserving data integrity under continuous load.
