8GB DDR4 2133MHz ECC UDIMM Server RAM

This 8GB DDR4 module runs at 2133MHz with CL15 latency and 1.20V voltage. It is built as an unbuffered ECC UDIMM using a 2Rx8 rank configuration for server and workstation systems. The module uses a major brand chipset and serves as a compatible replacement for the Hynix HMA41GU7MFR8N-TF part.

Straightforward DIMM installation with ECC checks

Installation follows the standard 288-pin DDR4 DIMM process and requires no special tools. The main issue arises when the motherboard or CPU does not support unbuffered ECC memory, causing the system to fail POST or ignore the ECC function. Always verify that the platform explicitly lists unbuffered ECC UDIMM support before fitting the module.

8GB capacity for light server workloads

The single 8GB stick handles typical entry-level server tasks such as file sharing, lightweight virtualization, or database caching with headroom for the operating system. Capacity runs out when running multiple heavy virtual machines, large in-memory databases, or compute clusters that demand more than 8GB of addressable memory per channel.

Questions about this item

How can I confirm the module is running at DDR4 2133 MHz with CL15 after installation?

Check the memory speed and latency in your system BIOS or with a tool such as CPU-Z; they should report 2133 MHz and CL15 at 1.20 V.

What comes in the package and is anything else required to install it?

The box contains one 8 GB DDR4 2133 MHz ECC UDIMM (288-pin); no extra parts are needed if your motherboard has a free DDR4 DIMM slot.

Should I choose the 2Rx8 version or look for a different rank configuration?

Select the 2Rx8 module when your server or workstation requires a dual-rank unbuffered ECC DIMM; verify the platform's qualified vendor list for exact rank compatibility.
