32GB DDR4 ECC UDIMM for workstations and NAS

This module is a 32GB DDR4 3200 CL22 ECC unbuffered UDIMM built for desktop PCs, workstations, servers and NAS systems. It runs at 1.2V and uses a 288-pin 2Rx8 layout. The part is a direct replacement for QNAP RAM-32GDR4ECK0-UD-3200 and RAM-32GDR4ECT0-UD-3200.

Build integration and system headroom

The stick fits standard 288-pin DDR4 slots and operates at PC4-25600 speed with CL22 timing. ECC support adds single-bit error correction for data integrity in always-on workloads. Backward compatibility covers 2133MHz, 2400MHz, 2666MHz and 2933MHz platforms, so it can slot into older boards without a BIOS update. No heat spreader is fitted, leaving clearance for large CPU coolers.

Who this suits and who should look elsewhere

The module suits administrators upgrading QNAP NAS units or building ECC-capable workstations and servers that need 32GB per slot. Buyers without ECC-capable chipsets, or those needing registered DIMMs or non-ECC memory, should select a different kit.

Questions about this item

How much capacity does this 32GB DDR4 3200 CL22 ECC Unbuffered UDIMM provide for sustained workloads?

This single module delivers 32GB of DDR4 memory at 3200MHz with CL22 latency, operating at 1.2V for stable performance in workstations, servers and NAS systems.

Does the OWC 32GB DDR4 3200 CL22 ECC Unbuffered UDIMM run hot or loud under continuous operation?

The module has no heat spreader and no active cooling, so it relies on case airflow; power draw stays at the standard 1.2V DDR4 level with no fan noise.

What motherboard slot and ECC support are required to use this 288-pin DDR4 3200 CL22 UDIMM?

You need a desktop or server board with a 288-pin DDR4 DIMM slot that accepts unbuffered ECC modules; the stick is backward compatible with 2133, 2400, 2666 and 2933MHz speeds.
