QNAP TVS-882/882T Memory Upgrade

This 8GB DDR4 module is built specifically for the QNAP TVS-882 and TVS-882T NAS systems. It adds capacity to compatible units that support non-ECC unbuffered memory. Buyers who need ECC protection or registered DIMMs cannot use this kit.

JEDEC-Standard 288-Pin UDIMM

The stick follows the PC4-17000 2133MHz CL15 specification at 1.2V with a 2Rx8 rank layout. No heat spreader is fitted, so it relies on system airflow. The 288-pin edge connector seats in standard DDR4 UDIMM slots on the target QNAP motherboards.

Verify Slot Count And Maximum Capacity

Check the NAS documentation for the number of available slots and the total memory ceiling before ordering. This single 8GB module fills one slot and may require pairing for dual-channel operation. Systems already at the supported limit will not accept additional modules.

Questions about this item

Will DDR4 2133 PC4-17000 CL15 run at full speed in my QNAP TVS-882?

Yes, this module is rated DDR4 2133 PC4-17000 CL15 and the TVS-882 memory controller supports that exact JEDEC standard, so it will operate at the rated 2133 MT/s without manual tuning.

Does the 288-pin unbuffered DIMM fit the TVS-882T memory slots without a heat spreader?

The stick is a standard 288-pin UDIMM with no heat spreader, matching the low-profile clearance inside the TVS-882 and TVS-882T chassis.

What is the correct orientation when seating this 2Rx8 module in the NAS?

Align the single key notch on the gold edge with the slot key, press straight down until both side latches click, and verify the module sits flush — the most common error is stopping before the latches engage.
