VIK-on successfully removed Micron 8Gb modules and replaced them with Samsung 16Gb on RTX 2070, which are listed in the board schematics. Apparently, the modification is as easy as replacing the modules and changing the resistors into a different binary code for RAMCFG jumpers. Normally such a modification is not allowed by NVIDIA and requires manufacturer’s support, however, the BIOS on this RTX 2070 appears to support such a capacity.
