Targeted 16 GB DDR4 upgrade

This kit delivers 16 GB of DDR4 2400 memory in two matched 8 GB SO-DIMM modules. It is built for owners of the ASUS ROG G20CB, G20CI and GR8 II compact desktops who want the maximum 32 GB capacity those systems accept. The CL17 unbuffered non-ECC design runs at the standard 1.2 V and fits the 260-pin slots without modification.

Dual-stick kit with standard SO-DIMM fit

Two 260-pin modules ship together so the memory controller can operate in dual-channel mode. No heat spreader is fitted, keeping the profile low enough for the tight chassis of the supported ROG models. Installation is a simple slot-in procedure; the 1.2 V rating matches the platform specification and requires no voltage adjustment in firmware.

Replaces the factory 8 GB or 16 GB configurations

The kit takes the system from the typical single-channel 8 GB or mismatched 16 GB up to a full 32 GB dual-channel limit. Buyers who already run 32 GB will see no capacity gain. The jump is worthwhile when the workload — virtual machines, large media projects or heavy multitasking — exceeds the current physical memory and forces paging to storage.

Questions about this item

Does the DDR4-2400 interface limit the 16GB kit to 2400 MT/s even if the ROG board supports faster memory?

Yes, the modules are rated DDR4-2400 (PC4-19200) so the system will run them at 2400 MT/s regardless of higher board capability.

Will the 260-pin SO-DIMM form factor fit the two SODIMM slots in a ROG G20CB, G20CI or GR8 II?

Yes, each stick is a 260-pin DDR4 SO-DIMM and the listed ROG desktops have two SODIMM sockets that accept this form factor.

What is the correct way to seat both 8GB sticks so the system recognises the full 16GB?

Insert each module at an angle into a slot, then press down firmly until the side clips click; both slots must be populated for the 16GB kit to be detected.
