Dell Precision 7875 memory kit

This 256GB kit contains four 64GB DDR5 ECC RDIMM modules built for the Dell Precision 7875 workstation. Registered buffering and error-correcting code protect data integrity in professional workloads. The kit runs at 4800MT/s with CL40 latency at 1.1V. It targets IT departments and power users who need maximum supported capacity.

288-pin RDIMM form factor

Modules use the standard 288-pin DDR5 RDIMM layout with 2Rx4 organisation and no heat spreader. Registered design reduces electrical load on the memory controller for stable operation across all four slots. The low 1.1V voltage matches the platform specification. Build quality relies on major OEM DRAM from Samsung, Micron or Hynix.

Lifetime replacement coverage

The package includes only the four memory modules; no extra cables, tools or software licences are supplied. NEMIX RAM stresses each kit under load before shipment to verify compatibility. A lifetime replacement warranty and US-based technical support back the upgrade. Buyers who need non-ECC memory or consumer overclocking profiles should look elsewhere.

Questions about this item

What DDR5 speed and CAS latency does this 256GB kit run at?

The kit operates at DDR5 4800 (PC5 38400) with CL40 latency.

Will these 288-pin RDIMMs fit the Dell Precision 7875 memory slots?

Yes, the 288-pin DDR5 RDIMM form factor matches the Precision 7875 DIMM slots.

How do I install the four 64GB modules in the correct channel order?

Populate all four slots following the motherboard manual channel sequence; the common error is skipping a slot or mixing channel pairs.
