Capacity and Compatibility
This is a single 32GB DDR4 UDIMM rated at 3200MHz with CL22 latency. It targets desktop PCs, workstations and NAS systems that accept standard 288-pin unbuffered non-ECC memory. The module runs at 1.2V and follows JEDEC PC4-25600 specifications.
Build and Installation
The black PCB has no heat spreader and no LEDs, keeping the profile low for tight DIMM slots. A 288-pin edge connector ensures standard keyed insertion on any compatible motherboard. Installation is a straightforward DIY task that requires no tools beyond opening the case.
Speed Limits and Backward Use
The DDR4 interface tops out at 3200MHz on this module, so the system memory controller will not run it faster. It will automatically down-clock to 2133MHz, 2400MHz, 2666MHz or 2933MHz when paired with slower platforms or mixed with existing sticks.

Questions about this item
Does the DDR4 3200 PC4-25600 rating cap the speed if my motherboard only supports 2666?
The module is backward compatible with 2133MHz, 2400MHz, 2666MHz and 2933MHz systems, so it will run at the highest speed your board allows.
Will this 288-pin UDIMM fit a standard desktop DIMM slot without a heat spreader?
Yes, it uses the standard 288-pin unbuffered DIMM form factor and has no heat spreader, so it fits any desktop DDR4 slot with normal clearance.
What is the correct way to seat the module, and what step do people often miss?
Align the notch with the slot key, press down firmly until both side clips click locked, and verify the module sits evenly — the most common mistake is stopping before the clips engage.
