ASUS ROG GX650RX-LB150W RAM upgrade specifications
The ASUS ROG Zephyrus Duo 16 model GX650RX-LB150W features two SO-DIMM slots for DDR5-SDRAM memory upgrades. Maximum supported RAM capacity reaches 64 GB total. Memory specifications include DDR5 modules operating at 4800 MHz frequency. Upgrade compatibility requires SO-DIMM form factor DDR5 memory modules. Current memory configuration and available upgrade slots enable system expansion to the specified maximum capacity.

Additional Notes
- The ASUS ROG GX650RX-LB150W uses SO-DIMM slots, which are laptop-specific form factors and cannot accept desktop DDR5 modules. Any RAM upgrade requires SO-DIMM variants exclusively.
- With 2 slots and a 64 GB maximum capacity ceiling, each slot supports 32 GB modules at maximum configuration. Single-slot upgrades beyond 32 GB are not possible; both slots must be populated to reach the upper limit.
- DDR5-4800 MHz operation indicates the system architecture supports the JEDEC DDR5 standard baseline frequency. Aftermarket DDR5 SO-DIMMs rated above 4800 MHz will operate at native 4800 MHz unless BIOS firmware explicitly enables XMP/EXPO profiles, which may void certain warranty protections.
- Upgrading from 2 lower-capacity modules to 2 higher-capacity modules requires full memory replacement rather than additive expansion. The original modules become surplus hardware without alternative internal connectivity paths.
- DDR5 SO-DIMM availability in retail channels remains constrained compared to DDR4 laptop modules. Lead times and pricing volatility for matching pairs may exceed those of previous-generation memory upgrades.
- Installation of SO-DIMM modules requires direct contact with the motherboard slot. Dust ingress into the SO-DIMM connector area during removal or installation can cause intermittent memory errors; external static discharge protection during the swap procedure is mandatory.
