De-lidding & Speed-binning Examined

Not many people will be willing to risk invalidating their warranty purely to achieve lower temperatures – the overall aim is to generally increase any overclocking headroom; that’s certainly the underlying aim when 8Pack performs the procedure, anyway.

A great alternative is to purchase a pre-delidded CPU from They offer a full years guarantee, the same as you would expect from an OEM chip, and take all of the risk into their own hands. Plus, you get the peace of mind that your chip will reach a decent overclock.

Having said that, we were interested to see what kind of difference de-lidding a chip could make to overclocking results. Before we set off down to Overclockers UK, we were unable to overclock our chip at all without hitting a thermal throttle, where the 7700K would automatically cut power to the silicon to prevent permanent damage.

Once we returned to the office, we were keen to crank up the settings and see what it was really capable of. Ian Parry kindly gave us some pointers before we were on our way, so we could hopefully eke out a little more performance from the Kaby Lake chip.

Our 7700K chip required 1.268V at 4.5GHz, when using the turbo-clock.

After tweaking in the BIOS and running an hour long Prime95 stress test, we found that 5.0GHz was stable at 1.360V, but pushing for 5.1GHz would cause instability within a few minutes – we could possibly push the voltage a little higher but we’re aiming for a 24/7 overclock at this time.

As you can see, the overclocked temperatures, with around 0.1v more than stock are still considerably lower than the stock Thermal Interface Material.
