Did someone know if it affect computing speed?

Tasks will take longer if you reduce the GPU memory speed. How much longer depends on how much you reduce the rate by, but there are other factors (GPU model, WU, GPU rate). Look at your run-times from same type of WU's to see.
It's still a good way to keep the heat, energy use and fail rate down.
