32GB ECC DDR4 module
This single 32GB DDR4 3200 CL22 DIMM adds ECC protection to compatible workstations, servers and NAS systems. It runs at 1.2V in an unbuffered 288-pin VLP form factor. The module targets users who need data integrity without registered buffering.
JEDEC DDR4 3200 limits
The stick follows the JEDEC PC4-25600 standard, so its maximum transfer rate is fixed at 3200 MT/s with CL22 timing. It cannot exceed that specification without manual overclocking, which the vendor does not endorse. Voltage is locked to 1.2V by the same standard.
32GB capacity headroom
One 32GB rank pair handles large datasets, virtual machines and ZFS caches comfortably. Workloads that exceed 32GB per slot will require additional modules or higher-density DIMMs not covered by this part. Mixing capacities or speeds is not recommended by the manufacturer.

Questions about this item
Does this module fit a standard 288-pin DDR4 desktop DIMM slot?
Yes, it uses the 288-pin DDR4 form factor used by most desktop workstations and servers that accept unbuffered ECC memory.
Can I mix this 32 GB stick with my existing non-ECC RAM?
Mixing ECC and non-ECC modules is not recommended; the system will typically disable ECC or fail to boot, so populate all slots with identical ECC modules.
What does the CL22 rating mean for real-world responsiveness?
CL22 indicates 22 clock cycles of CAS latency at 3200 MT/s, which is standard timing for JEDEC DDR4 3200 and delivers stable throughput for server and NAS workloads.
