Upgrade for Hynix DDR5 modules

This 16 GB DDR5 module replaces Hynix part numbers HMCG78MEBUA081N and HMCG78MEBUA084N. It delivers 4800 MT/s speed at CL40 latency with standard 1.1 V operation. The non-ECC unbuffered design fits mainstream desktop platforms.

Standard DDR5 DIMM format

The 288-pin DIMM follows the DDR5 specification without extra software or accessories. Green PCB colour identifies the module visually inside the chassis. No bundled utilities change the behaviour; the memory runs at rated JEDEC timings.

Tested reliability for daily use

Every unit passes A-Tech quality-assurance testing before shipment. The 1.10 V rating matches DDR5 baseline voltage for broad motherboard compatibility. Lifetime warranty and US-based technical support back the purchase.

Questions about this item

Will the green heatsink need re-pasting or fan cleaning over time?

The module has no heatsink or moving parts; only the gold edge contacts may need occasional reseating if the system is moved.

At CL40 and 4800 MT/s, what bottleneck appears first during long workloads?

The CAS-40 latency and 4800 MT/s data rate set the throughput ceiling before thermal limits are reached.

How much heat and noise does the 1.1 V stick add when running all day?

At the standard 1.1 V DDR5 voltage the module runs passively, adding no fan noise and only minimal warmth to the chassis.
