Nick Shih, legendary overclocker who now works with ASRock, has just posted on his wall a CPU-Z screenshot validating one of the biggest overclocks I've seen in quite sometime: an Intel Core i7-4790K CPU clocked at an incredible 7GHz, or 7003.38 MHz.
Shih used the ASRock Z97 OC Formula motherboard to get there, and a huge 1.792V on the CPU to reach the milestone. The Core i7-4790K used was an Engineering Sample (like most for these overclocks) with two cores disabled. But still, 7GHz! Wow.
The picture above is what Shih is working with, just as a teaser. Shih has even teased that 7.2GHz "is coming" - we await your overclocking skills, Nick!
