8GB DDR5 4800 UDIMM for desktop upgrades
This OWC module provides 8GB of DDR5 memory at 4800MHz with CL40 latency. It uses a standard 288-pin unbuffered DIMM form factor and runs at 1.1V. The non-ECC design targets mainstream desktop, workstation, NAS and all-in-one systems.
JEDEC and ROHS compliance with verified
The stick meets JEDEC specifications and is ROHS compliant, making it a warranty-safe upgrade. OWC validates compatibility against Hynix part numbers HMCG66MEBUA081N and HMCG66MEBUA084N. No heat spreader or LED lighting is included.
Suits users adding capacity to DDR5 platforms
Buyers with DDR5-capable desktops, workstations or NAS units can install this single module to increase memory. Systems requiring ECC, registered DIMMs or speeds above 4800MHz should select different memory.

คำถามเกี่ยวกับสินค้านี้
Will the 1.1V DDR5 module need any firmware updates or capacitor replacements over its lifetime?
The module is a standard JEDEC 1.1V DDR5 UDIMM with no onboard firmware or user-serviceable capacitors, so no scheduled updates or component swaps are required.
What thermal limit appears first when the CL40 4800MHz stick runs at full load for hours?
With no heat spreader, the DRAM packages themselves hit their maximum junction temperature before the PCB or surrounding components become the bottleneck.
How much extra power draw and fan noise does the 8GB 1Rx16 DIMM add during all-day operation?
At the rated 1.1V the module draws only a few watts, adding negligible heat that existing case airflow handles without any audible fan-speed increase.
