In my particular case, I didn't consider it was worth the additional $150CAD to go from a non-K to a K CPU. So your max stable GHz might not be much over the stock 5GHz. 11th gens run hot! Overclocking also requires a good motherboard and CPU power delivery, and all clues seem to indicate that the MBs Dell puts in these computers are not really at that level. From what I've read/seen, the best you can hope for with a 11700k is to bump the boost clock to 5.2-5.3 GHz, but it will require a LOT of cooling. This is best done in the BIOS, as you will likely also need to increase core voltage to support the higher frequency. Actual overclocking (changing the ratio/multiplier).Intel XTU is pretty limited in that respect, but ThrottleStop (freeware) can easily help you set the time limit to a ridiculous number (millions of seconds). The good news here is that you can remove that limit so that your CPU can maintain boost forever (assuming adequate cooling). After that, the CPU goes back down to non-boost frequency for a while, then boosts back up for that time period (called Tau), and so on. It varies from CPU to CPU, but it's around 30-45 seconds. As soon as more cores kick in, or temps go higher, the max freq starts dropping. That 4.9 or 5.0 GHz number there is achieved only when 1 core is under heavy load and temps are under 70 degrees. This speed is achieved based on how many CPU cores are under load at the same time. This is not technically overclocking and works with non-K CPUs as well. Intel TurboBoost (that higher GHz number you see in the CPU specifications).
