I haven't had anything from the past 5 years from them but nothing I tested was overclocked in any way. The proprietary motherboards didn't even have xmp or multiplier control. And the gpus are usually the cheapest blower models which aren't capable of sustaining the advertised boost clocks.

Don't think any Alienware pc is ever running near the limits of the hardware, it's just a shitty dell prebuilt covered in cheap plastic and LEDs.
