4GB DDR4 2400 ECC UDIMM Server Memory

This A-Tech module delivers 4GB of DDR4 2400 ECC unbuffered memory for server and workstation systems. It operates at CL17 latency with standard 1.20V voltage and uses a 1Rx8 rank configuration on a 288-pin DIMM. The module serves as a compatible replacement for the Kingston KVR24E17S8/4 part number.

Suits ECC UDIMM Slots Only — Not Registered Systems

This memory fits motherboards that accept unbuffered ECC UDIMM modules. It will not work in platforms requiring registered or load-reduced DIMMs. Buyers needing larger single-module capacities or higher frequency ratings should verify their board specifications before purchasing.

DDR4 2400 Speed Decides Compatibility

The module runs at DDR4 2400 (PC4-19200) with CL17 timing. Your system must support this exact speed grade and unbuffered ECC operation for the RAM to function correctly.

Questions about this item

My motherboard has four DDR4 DIMM slots — will this 288-pin UDIMM fit?

Yes, the module uses the standard 288-pin DDR4 UDIMM form factor and will install in any compatible DDR4 DIMM slot.

Can I mix this ECC unbuffered stick with the non-ECC DDR4 2400 modules already in my workstation?

Mixing ECC and non-ECC memory is not recommended; the system will typically disable ECC and may default to the lowest common speed or fail to boot.

After installing the RAM, how do I confirm the module is running at DDR4 2400 with ECC active?

Enter the BIOS/UEFI or use a tool like CPU-Z on Linux/Windows — verify the speed reads 2400 MT/s, CL17 timings, and ECC status shows enabled.
