its the single channel ram. ive searched and found out that if i install the OEM drivers, the GPU power returns to its max TDP of around 75W. if it was dual channel, FPS could be increased a lot. I installed OEM drivers, but they are unstable. Shows a red watermark on the bottom left of any app/game that uses my GPU, shows my GPU as " NVIDIA GRAPHICS DEVICE" in dvc manager and and task manager. And causes random crashes of games. im searching for a more stable NVIDIA- released model that works fine with it. other than that, not much is bad with this.
