128GB DDR5 ECC Kit for Workstations

This 128GB kit contains eight 16GB DDR5 5200 modules rated at CL42 latency and 1.1V. It is built for desktop workstations, servers and NAS systems that require error-correcting memory. The unbuffered design fits standard 288-pin UDIMM slots.

JEDEC-Compliant Unbuffered UDIMMs

Each module follows JEDEC and RoHS standards and carries no heat spreader, keeping the profile low for dense server chassis or compact workstation boards. The black PCB and standard 288-pin edge connector allow straightforward installation in any compatible DDR5 UDIMM slot without clearance issues.

ECC Unbuffered at 5200 MT/s

The combination of ECC protection and unbuffered signalling at 5200 MT/s is the specification that determines whether this kit matches your platform. Only systems that explicitly support DDR5 ECC UDIMMs at this speed and voltage will operate correctly.

商品問答

Will this 128GB kit run at 5200MHz on my workstation motherboard?

The modules are rated for 5200MHz CL42 at 1.1V. Your motherboard must support DDR5 ECC unbuffered UDIMMs and have eight 288-pin slots to use the full kit at that speed.

Do I need a CPU that supports ECC memory for this kit to work?

Yes. ECC unbuffered DIMMs require a processor and chipset that explicitly support ECC. Without that support the system will either disable ECC or fail to post.

Can I mix these 16GB modules with the 8GB sticks already in my server?

Mixing capacities is not recommended. For stable dual-channel operation across all eight slots, populate every slot with identical 16GB modules from this kit.
