System-Specific DDR5 Module

This NEMIX RAM module delivers 32GB of DDR5 4800 memory built for the QNAP TS-H3077AFU NAS. It operates at 1.1V with CL40 latency in a 2Rx8 configuration. The 288-pin UDIMM fits the system memory slots without a heat spreader. Major OEM chips from Samsung, Micron or Hynix provide the underlying components.

NAS Upgrade Fit

The stick suits owners of the TS-H3077AFU who need a single 32GB DDR5 4800 module to expand capacity. Buyers requiring ECC error correction must choose a different part because this module is non-ECC. Systems that demand registered or buffered memory cannot use this unbuffered UDIMM. Anyone needing a matched kit of two or more modules should look elsewhere.

Decisive Compatibility Spec

The module is validated specifically for the QNAP TS-H3077AFU and carries part number MD38400-328K1. DDR5 4800 speed, 1.1V voltage and 288-pin UDIMM form factor must match the NAS memory specifications exactly. Confirm the system accepts non-ECC unbuffered 2Rx8 memory before ordering. Only the listed QNAP model is guaranteed compatible.

Questions about this item

Will the memory chips need any active cooling or maintenance after installation?

The module has no heat spreader and runs at 1.1 V; no user maintenance is required once it is seated in the 288-pin slot.

Which specification caps sustained throughput first — the CL40 latency or the 4800 MT/s data rate?

The 4800 MT/s transfer rate sets the maximum bandwidth ceiling; CL40 timing determines access delay within that limit.

How much extra heat or fan noise does the 1.1 V DDR5 module add during all-day NAS operation?

At 1.1 V without a spreader the module draws minimal power, so it adds negligible heat and no audible noise to the chassis.
