I want to run 3DMark 2000 on an RTX 2060 (6Gb), on Win 7 64 bit. It ran ok with a GTX 670 (2Gb), but it refuses to run with the RTX, complaining about not enough memory. I think that it fails to recognize more than 2Gb of video ram (it says also that it has negative amount of texture memory. So, I want to try to reduce the memory of the RTX to 2 Gb or less, without editing the BIOS. There is any overclocking tool that allows to reduce video ram?
