I taj overclock je napuhan gro, nije to mnogo bolje od broadwell-e

The results were mixed, my chip only managed a stable 4.6GHz overclock, no matter how much voltage I threw at it I wasn't able to stabilize anything beyond that. The system would boot into Windows but would blue screen within the first few moments of running a stress test. Stability might improve with future BIOS updates, or perhaps I just have a dud. Looking around the Internet it seems others are also stuck at 4.6GHz like me while some folks have managed to stabilize their system at 4.7 or 4.8GHz.

However, the frequency isn't my greatest concern right now. Using just 1.2 volts, which is all I needed for a stable 4.6GHz overclock on all cores, the system consumption went from the 259 watts just seen to an insane 402 watts! That might not even be the worst part, the deal breaker is probably the operating temps. Chilling the 7900X was Corsair's H100i v2 and despite being a premium 240mm AIO liquid cooler, temps skyrocketed as the CPU was place under load, reaching 90 degrees instantly before climbing further towards 100 degrees. Unless you have an amazing cooler, I'm not sure overclocking is going to be worth it.

Overclocking the Core i9-7900X

Though my time with the ASUS X299-Deluxe and the Core i9-7900X was short, I was able to get our sample overclocked to an impressive state. With a core voltage of 1.28v I was able to push all cores to a 4.6 GHz and run the system mostly stable.

However, temperatures at this point would spike to over 100C (!!) and level off in the mid-90C range, which was too hot for me to run for an extended period with a clear conscious, even with a Corsair H100i GTX as the cooler.

So far, the 7900X is running hot – overclocking got us stuck at around 4.5GHz/1.275V with a 90-95C package temperature when using a Kraken X62, and can increase power draw into a couple hundred watts.
