Lenovo-Compatible 8GB DDR4 RDIMM

This 8GB registered DDR4 module runs at 2133 MT/s with CL15 latency and 1.20V operation. It uses a 2Rx8 organisation and 288-pin form factor for server platforms. ECC and registered buffering protect data integrity in multi-socket systems. The part matches Lenovo part number 4X70G78061 and is built with major-brand DRAM chips.

Upgrade from lower-capacity or non-ECC UDIMMs

Replacing unbuffered memory with this registered RDIMM enables larger total system memory and error correction. The jump is worth it when your workload demands capacity beyond UDIMM limits or requires ECC for data integrity. Systems limited to unbuffered memory or a lower maximum speed will not benefit from the registered design.

DDR4-2133 registered interface limits

The DDR4-2133 interface caps bandwidth at the PC4-17000 rate, so faster CPUs or chipsets cannot push this module higher. Registered buffering adds one cycle of command delay, which slightly increases latency versus unbuffered modules at the same speed. Mixing registered and unbuffered DIMMs is not supported on the same memory channel.

Questions about this item

Will this 288-pin DDR4 RDIMM fit my Lenovo server’s memory slots?

Yes, the 288-pin DDR4 registered form factor matches the standard server DIMM slots used by Lenovo systems that accept the 4X70G78061 part number.

What is the correct way to seat this registered module so the server recognises the full 8 GB?

Align the key notch with the slot, press straight down until both side latches click, and verify the 2Rx8 organisation appears in BIOS — partial insertion is the most common reason the capacity is not detected.

When should I plan to replace this 1.20 V DDR4-2133 stick in a production server?

Registered ECC modules of this specification typically run for the life of the platform; replace only if BIOS logs correctable errors that exceed the platform’s threshold or if a firmware update explicitly requires a newer revision.
