QNAP TS-H1277AXU-RP Memory Upgrade

This 64 GB kit contains four 16 GB DDR5 modules built for the QNAP TS-H1277AXU-RP NAS. It runs at 4800 MT/s with CL40 latency at 1.10 V. The unbuffered, non-ECC UDIMMs use major-brand DRAM chips and are validated for that specific system.

Replaces Slower or Smaller DDR5 Kits

Swapping the factory memory for this kit adds capacity and keeps the native 4800 speed when the NAS workload outgrows the original configuration. The upgrade is worthwhile when virtual machines, containers or large file caches need more than the stock amount.

Tool-Free Installation With Standard Slots

The 288-pin UDIMMs drop into the NAS memory slots without adapters or cables. Common issues are mixing these non-ECC sticks with ECC modules or leaving a slot empty in a channel that expects a matched pair.

Questions sur cet article

What physical slot does the 288-Pin DDR5 UDIMM kit need to fit in the QNAP TS-H1277AXU-RP?

The kit uses standard 288-Pin DDR5 UDIMM slots; the NAS provides four such slots for the 4 x 16 GB modules.

Which step is often missed when installing the 1.10V CL40 modules in this NAS?

After seating each module, the ejector clips must click fully shut; a loose clip leaves the stick unrecognised at boot.

What component of the 1Rx8 DDR5 4800 kit will need replacement first in continuous operation?

The DRAM chips themselves set the service life; they are rated for standard JEDEC endurance and are not user-serviceable.
