System-specific DDR4 kit

Computer Memory Solutions CM4096722133ECCR is a 64 GB kit containing two 32 GB DDR4 2133 MHz ECC registered DIMMs. It is built for Dell PowerEdge FC430 and Precision Workstation T5810 or T7810 systems that require registered, error-correcting memory. The modules run at 1.2 V with CL15 15-15-15 timings and use a 2Rx4 organisation on 288-pin PCBs.

Upgrade from non-ECC or lower capacity

The kit replaces standard unbuffered memory or smaller registered modules in the supported Dell platforms. The jump is worth it when the workload demands data integrity through ECC and the motherboard requires registered DIMMs to populate all available slots. Systems limited to unbuffered memory cannot use these modules.

64 GB capacity with 256 GB headroom

The 64 GB total handles virtualisation, large datasets and multi-user workloads comfortably within the platform limits. Each supported system accepts up to 256 GB using four sockets per CPU or eight sockets with two CPUs, so this kit leaves room for further expansion. It will not suit builds that need unbuffered memory or consumer desktop platforms.

Questions about this item

Will the 288-pin DDR4 DIMMs fit the Dell PowerEdge FC430 memory slots?

Yes, the 288-pin DDR4 form factor matches the FC430 slots exactly; each 32 GB module seats in a standard DDR4 DIMM socket.

What is the correct order for populating the 32 GB sticks in the Precision T5810?

Install the two modules in the two sockets belonging to the same memory channel — typically the first slot of each CPU channel — so the registered ECC timing initialises correctly.

When should the 2Rx4 registered ECC modules be replaced in a T7810 running continuous workloads?

Replace them if the system logs corrected ECC errors that climb steadily, or after the platform reaches its 256 GB maximum and you need higher capacity.
