Server memory kit for DDR4 ECC platforms

This 32 GB kit contains two 16 GB DDR4 2933 MHz ECC UDIMM modules built for servers and workstations that support unbuffered ECC memory. Each module is dual rank x8 with a CAS latency of CL21 and operates at the standard 1.2 V. The 288-pin DIMM form factor fits compatible DDR4 server and workstation motherboards only.

Suited for ECC UDIMM systems, not desktops

This memory is designed for servers and workstations that explicitly support DDR4 ECC unbuffered DIMMs. It will not function in standard desktop or laptop computers that lack ECC UDIMM support. Buyers who need non-ECC memory for consumer platforms or registered DIMMs for registered-only servers should select a different kit.

Verify DDR4 ECC UDIMM support before ordering

Check your system manual or vendor documentation to confirm the platform accepts DDR4 ECC unbuffered DIMMs at 2933 MHz with a dual rank x8 configuration. Ensure the motherboard has enough free 288-pin slots for two modules and follow the recommended slot population order for multi-channel operation.

商品問答

Does my motherboard need DDR4 ECC unbuffered UDIMM slots for this 288-pin kit?

Yes, the kit is built for servers and workstations that accept DDR4 ECC unbuffered UDIMM modules in 288-pin slots. It will not work in desktop or laptop systems.

Will these 2933 MHz modules run with older DDR4 memory rated at lower speeds?

The modules operate at 2933 MHz (PC4-23400) and will downclock to match the slowest installed DDR4 memory, though mixing ranks or ECC types is not recommended.

How can I confirm the kit is running at 2933 MHz with CL21 after installation?

Check the memory speed and CAS latency in the system BIOS or a hardware monitoring tool; they should report 2933 MHz and CL21 when the kit is seated correctly.
