128GB DDR5 ECC UDIMM kit

This OWC kit provides 128GB of DDR5 memory in four 32GB unbuffered UDIMM modules. It is built for workstations, servers and NAS systems that require error-correcting code memory. The modules run at 5200MHz with CL42 latency and operate at 1.1V.

Check DDR5 ECC UDIMM support

Verify that your motherboard or system accepts 288-pin DDR5 unbuffered ECC UDIMMs before ordering. Confirm the platform can run memory at 5200MHz and that it supports a total capacity of 128GB across four slots. Ensure the BIOS is updated to recognise the modules.

Four-module population for multi-channel use

The four sticks populate dual-channel or quad-channel configurations depending on the platform. No heat spreader is fitted, so clearance around the slots remains open. The 1.1V operation keeps power draw low for dense server or workstation builds.

商品問答

Does the 128GB kit include all four 32GB DDR5 modules or must any be purchased separately?

The kit contains four 32GB DDR5 5200 CL42 ECC unbuffered UDIMM modules, totalling 128GB, so nothing else needs to be bought.

Should I choose the 5200 CL42 version or a different speed for a workstation that needs ECC?

This 5200 CL42 kit is the only ECC unbuffered DDR5 option listed; select it when your platform requires DDR5 5200 with error correction.

What does the 5200 CL42 rating mean once the modules are installed in a desktop?

The memory runs at 5200 MT/s with a CAS latency of 42 cycles at 1.1V, delivering JEDEC-standard DDR5 bandwidth and ECC protection for data integrity.
