8GB DDR4 ECC UDIMM for servers

This 8GB DDR4 ECC UDIMM module runs at 2400MHz with CL17 latency and 1.20V operation. It is built for server and workstation systems that require error-correcting unbuffered memory. The single-rank 1Rx8 design uses major-brand chips on a 288-pin DIMM. Buyers needing registered or load-reduced DIMMs cannot use this module.

Sustained 2400MHz operation with ECC

Under continuous workloads the module maintains its rated 2400MHz speed while ECC corrects single-bit errors in real time. The 1.20V standard voltage keeps power draw consistent during extended compute tasks. CL17 timing remains stable without thermal throttling in properly cooled chassis. Systems without ECC support in the BIOS will not benefit from error correction.

Simple 288-pin DIMM installation

The UDIMM form factor fits standard DDR4 DIMM slots with a straightforward press-in action until the retention clips click. No driver or firmware update is required for the memory itself. Compatibility issues usually arise when mixing this unbuffered ECC module with registered DIMMs or when the motherboard limits maximum capacity per slot. Verify the platform supports unbuffered ECC before installing.

Questions about this item

How much heat does the 1.20V DDR4 module add when running 24/7 in a server?

At 1.20V standard DDR4 voltage the module draws minimal power, so heat output stays low even during continuous operation.

What must my motherboard provide to use this ECC UDIMM?

The board needs a 288-pin DDR4 slot that supports ECC unbuffered memory and can run at 2400 MHz with CL17 timing.

Will this 1Rx8 stick work alongside my existing Samsung M391A1K43BB1-CRC modules?

Yes, it is built as a compatible equivalent to that Samsung part number, matching speed, voltage, rank and ECC type for mixed-population stability.
