8GB DDR4-2400 ECC UDIMM for desktop workstations

This 8GB DDR4-2400 module runs at PC4 19200 with a 1.20V operating voltage. It is an unbuffered UDIMM that includes ECC error correction for data integrity. The black PCB suits standard desktop workstations and entry-level servers that accept unregistered ECC memory.

Check motherboard support for unbuffered ECC DDR4

Verify that your board explicitly lists support for unbuffered ECC UDIMMs at DDR4-2400 speed. Many consumer desktop chipsets disable ECC functionality even when the slots accept the modules. Confirm the maximum capacity per slot and the total number of available slots before ordering.

Low-voltage operation keeps thermals modest

At 1.20V the sticks run cool inside typical chassis airflow without requiring extra cooling. Passive operation means zero fan noise from the memory itself. The modest power draw leaves ample headroom on the motherboard memory voltage regulator during sustained workloads.

Questions about this item

Does the 8GB DDR4-2400 2RX8 ECC UDIMM module come alone or with extra parts?

The module is supplied as a single stick. No extra brackets, cables or software are included, so nothing else needs to be bought separately for installation.

How do I decide between the 2400 MT/s speed and the PC4 19200 bandwidth rating?

They describe the same module. 2400 MT/s is the data rate; PC4 19200 is the peak transfer rate in MB/s. Choose by matching the motherboard's supported DDR4 speed.

What does the 1.20V voltage mean when the RAM is running in a desktop?

It is the standard DDR4 operating voltage, so the module runs at the default 1.20V without needing manual BIOS adjustments or extra cooling.
