8GB DDR4 3200 desktop module

This 8GB DDR4 3200 UDIMM is built for desktop PCs, workstations and NAS systems that use 288-pin unbuffered memory. It runs at the JEDEC-standard PC4-25600 speed with CL22 timing and 1.2V operation. The module is a direct replacement for the QNAP RAM-8GDR4T0-UD-3200 part number.

Thermals noise and power draw

Operating at 1.2V keeps power draw low and heat output minimal in normal desktop workloads. The module has no heat spreader and no onboard LEDs, so it adds no extra thermal mass or light. Silent passive cooling is sufficient for typical use.

Compliance and installation support

Full JEDEC and RoHS compliance makes the upgrade warranty-safe for OEM systems. OWC provides an advanced replacement programme and free technical support for the lifetime of the module. A basic installation video is available to guide first-time builders through the DIY process.

Questions about this item

How do I install this 288-pin UDIMM, and what step do people often miss?

Align the notch with the slot key, press firmly until both retention clips click, then verify the module sits flush; the step many miss is confirming the clips have fully locked on both sides.

What maintenance or replacement will this 8GB DDR4 module need later?

No scheduled maintenance is required; if a fault occurs the module is covered by OWC's limited lifetime warranty and advanced replacement programme.

What limit appears first when this CL22 3200MHz memory runs under sustained load?

The CAS latency of 22 cycles at 3200MHz sets the primary timing ceiling during continuous operation.
