Dell Precision 7875 memory kit

This 128GB kit is built for the Dell Precision 7875 workstation. It contains four 32GB DDR5 ECC registered DIMMs that install directly into the system's 288-pin slots. The modules are validated for the platform's specific memory controller and firmware requirements.

Registered ECC DDR5 at 4800 MT/s

The decisive specification is registered ECC DDR5 running at 4800 MT/s with CL40 latency at 1.10V. This combination matches the workstation's qualified memory profile and enables error correction for data integrity. Unbuffered or non-ECC modules will not function in this system.

Four matched modules in one kit

The package delivers four identical 2Rx8 modules pre-tested as a matched set. This eliminates the guesswork of mixing individual sticks and ensures the workstation populates all channels correctly for maximum bandwidth. No extra cables, brackets or software are included.

Questions about this item

What does the 4800 speed rating mean once the memory is installed in a Precision 7875?

The modules run at DDR5 4800 with CL40 timing, delivering the standard JEDEC data rate for this workstation platform.

How does the PC5-38400 designation and registered ECC design affect real-world use?

PC5-38400 is the JEDEC peak bandwidth label for DDR5 4800; registered ECC adds a buffer cycle for signal integrity and error correction in server workloads.

Will the 288-pin RDIMM modules fit the Dell Precision 7875 memory slots without extra hardware?

Yes, they are 288-pin DDR5 RDIMMs built to the Dell Precision 7875 form factor and install directly into the workstation's DIMM slots.
