A lot of people in the comments seem to not understand that overclocking IS running the hardware outside the specs, unless that hardware was specifically meant to do that.

It’s exactly like overclocking GPUs in the late 90’s, for them to fry themself after a month. You went outside ther specs for doing that. Even if I replace the speaker from a telephone, and the keypad stops working a month later, I have voided the warranty already by doing the speaker change as they can’t know if the now not working keypad was done because of you or a failing unit.

One of the refunds reasons you can select is “the game doesn’t run on my PC”. This is completely valid.
