8GB DDR4 2400MHz ECC UDIMM

This 8GB DDR4 module runs at 2400MHz with CL17 latency and 1.20V operation. It is an unbuffered ECC UDIMM built with a 1Rx8 rank configuration using major brand chips. The 288-pin DIMM targets server and workstation systems that require error-correcting memory.

ECC unbuffered DDR4 compatibility

The single specification that decides fit is the ECC unbuffered DDR4 2400MHz UDIMM format. Your motherboard must accept unbuffered ECC modules at this speed and voltage; registered or non-ECC DIMMs are not interchangeable with this part.

Suits servers needing ECC UDIMM upgrades

It suits administrators upgrading Dell systems referencing part numbers A9652462, A9654881, SNPMT9MYC/8G or MT9MY. Builders whose platforms require registered RDIMMs, non-ECC memory, or speeds other than DDR4 2400MHz should look at a different module.

Questions about this item

What does the 2400MHz rating mean once the module is installed in a server?

The module runs at 2400 MT/s, delivering a peak bandwidth of PC4-19200 on any DDR4 platform that supports this speed.

How does the DDR4 UDIMM interface limit performance in practice?

As an unbuffered ECC DIMM, it connects directly to the memory controller without a register, so the 2400 MT/s data rate and CL17 latency are the practical limits.

What physical slot and clearance does this 288-pin DIMM need?

It fits a standard DDR4 288-pin UDIMM slot and uses the 1.2V DDR4 voltage, so no extra power connectors or special cooling are required.
