Is Turbo Boost combined with manual overclock safe to use?
So I'm just starting out with overclocking and trying to achieve a solid boost on my i5-6600K which is already at base 3.5. I followed a tutorial and set it to 4.2, everything worked well during the stress test with y-cruncher and cinebench r20—no crashes, just fine. When I tried running a game, Task Manager showed 5.0ghz instead of the expected 4.2. I figured it was due to Turbo Boost and managed to disable it by switching Power settings from Performance to Balanced. Now that I understand, it technically handled the higher speed during testing, but I'm curious—would running at 5.0ghz for a few hours be okay given my VCore is only at 1.250?
Turbo Boost should be disabled in the BIOS not Power Options. Task manager readings are not the most reliable. My 3570K would show some ridiculous number like 5.3Ghz with Turbo Boost in Task Manager.
It's perfectly safe. The issue with Turbo Boost and overclocking is it can add an element of instability. If the Turbo Boost pushes the CPU beyond what it's current OC settings can handle the system will crash. Generally one would disable Turbo Boost and fine tune their OC settings. Then once you know the stable threshold of your CPU. If you want to start tweaking more. Tweak your Turbo Boost settings. To see if you can get a couple extra tenths of a ghz on 1, 2, 3, &c cores.
As long as your system remains stable. There is no need to turn off Turbo Boost. Since your temps and VCORE are still fine. Although if you can Turbo Boost to 5Ghz. You may be able to go a little higher than 4.2 on your current VCORE or drop your VCORE a little for greater energy efficiency.
I thought the same too, but couldn't disable Turbo Boost. I checked and if your system is on Performance Power, it activates automatically on new CPUs. After updating to the latest BIOS on my z170a, Turbo Boost was turned off again and now it's enabled once more. It's a bit annoying, but it doesn't start automatically anymore. Since then I've pushed up to 4.4GHz and everything runs smoothly through AIDA64 and CinebenchR20. I'm about to run a full gaming test tonight to see how it performs. Thanks for letting me know about Turbo Boost—I didn't realize there were settings that could be changed.
