Like previous generations, the Intel Core i9-9900K is unlocked and also has flexible attributes in terms of the BCLK and ratio/multiplier. This makes the job of overclocking much easier.

GIGABYTE has built Designare to have a solid digital VRM design with useful overclocking options within the BIOS too. We were able to shift the clock frequency up to 5.2GHz but no amount of voltage would allow us to gain stability. After repeated attempts, we finally settled at 5GHz as our stable maximum overclock – with 1.35v being required.


With the 5GHz overclock still applied – above is the result for the VRM temperatures, this test is run for over an hour, the temperatures hitting 70C.
