**64GB RDIMM can ONLY be used on 2nd Generation Xeon Scalable x2xx Series (Cascade Lake-SP) processors!** Faster memory will clock down to run at optimal speed depending on processor model installed. This system supports Registered RDIMM and Load Reduced LRDIMM memory modules. Modules of different memory types CANNOT be mixed within the same system. If only one processor is installed, only 12 DIMM sockets can be populated. With two processors, all 24 DIMM sockets can be populated.
Compatible with: Dell Precision 7820 Tower
Lifetime exchange or repair warranty against manufacturing defects by Computer Memory Solutions. Manufactured by Computer Memory Solutions. We don't use OEM or Generic Modules to avoid incompatibility. In most cases, you can mix manufacturer parts, however, all memory in the system will run at the slowest performance of the installed modules or CPU/processor capability.
To maximize performance, we recommend that you install your memory modules in matched pairs. A 64-bit Operating System is required to utilize more than 4GB of memory.
