Targeted Server Upgrade

This 64 GB kit delivers four 16 GB DDR4 2133 MHz registered ECC DIMMs built for the Dell PowerEdge T430. Each module runs at CL15 1.2 V with a 2Rx4 organisation and 288-pin form factor. The memory is validated for the system's registered ECC requirement and ships as a matched set of four sticks.

Capacity Step and Compatibility Rules

The kit raises a T430 from smaller configurations toward the 192 GB registered ECC ceiling, or 384 GB when 32 GB modules are used. The platform provides eight sockets for the first CPU and four for the second; mixing registered and unbuffered ECC is not supported. Four-gigabyte registered modules exist in both x4 and x8 variants, which must not share a memory bank.

Platform Limits and Practical Constraints

The T430 architecture caps registered ECC capacity at 192 GB with current 16 GB DIMMs and requires identical modules within each bank. Population rules restrict upgrades to the socket counts defined for each processor, so a second CPU is needed to access the full eight-plus-four layout. DDR4 2133 sets the speed ceiling for this generation.

Questions about this item

Does the 288-pin DDR4 form factor fit the Dell PowerEdge T430 memory slots?

Yes, the 288-pin DDR4 registered DIMMs are the correct physical format for the PowerEdge T430's memory sockets.

What is the correct installation sequence for the four 16 GB modules across the eight CPU 1 sockets?

Populate identical 2Rx4 modules within each memory bank; do not mix the x4 and x8 4 GB variants in the same bank.

When should the registered ECC modules be replaced if correctable error counts start rising?

Replace modules when the system logs show increasing correctable ECC errors, indicating cell degradation.
