Unfortunately, this isn’t entirely true because there are some downsides to the process. On paper, overclocking your GPU probably seems like a win-win scenario. In most cases, this will mean adjusting the fan speed as that’s how the majority of graphics cards are made. Making the GPU run at a higher speed than the manufacturer intended will make it run hotter, thus increasing the demand for cooling. Overclocking VRAM allows for faster data transfer between itself and the GPU, which leads to higher-quality images being processed.Īnother part of the overclocking process is adjusting the cooling. To avoid any confusion, we’ll stick to simply referring to the entire process as GPU overclocking. Part of this performance boost is seen via VRAM overclocking, which is often considered part of the overclocking process and not specifically referenced. When the GPU works at a higher clock, it performs more operations in a given period of time, which in turn means that you will see more frames per second. Briefly, overclocking means adjusting your GPU to work at a higher clock, hence the name.
