Precision 7820 Compatible Memory

This 16GB kit supplies two 8GB DDR4 RDIMM modules built for the Dell Precision 7820 tower workstation. The registered ECC design targets professional workloads that demand error correction and stable multi-module operation.

DDR4 2933 Registered Constraints

The DDR4 2933 interface runs at 1.2V with a CL21 latency, and the registered buffer adds one cycle of address/command delay that limits maximum clock headroom compared with unbuffered modules. Systems must support ECC RDIMM topology; consumer boards that accept only UDIMM will not post with this kit.

Major OEM Chipset and 288-Pin Layout

Chips sourced from Samsung Micron or Hynix are mounted on standard 288-pin RDIMM PCBs without heat spreaders, keeping the profile low for dense server chassis. The 1Rx8 organisation means each module presents a single rank, simplifying memory-controller training but capping total capacity per channel at two ranks.

Questions about this item

Is the 16GB kit the only capacity available for the Dell Precision 7820?

The listing shows a 16GB kit built from two 8GB modules. Other capacity kits may exist but are not covered by this product page.

What does the 2933MHz rating mean once the memory is installed in the Precision 7820?

The modules run at DDR4 2933 (PC4-23400) with a CAS latency of CL21 at 1.2V, delivering the rated throughput when the workstation configures them at that speed.

How does the 288-pin RDIMM interface affect what the system can use?

The 288-pin DDR4 RDIMM form factor with ECC and registered buffering is required by the Precision 7820; unbuffered or non-ECC DIMMs will not work in this platform.
