Overclocking isn't possible when Turbo Boost is active.
Overclocking isn't possible when Turbo Boost is active.
Hi, I have an i7 7700k and Asus Maximus IX Hero.
I plan to make a small overclock and turn off Turbo Boost just to be safe, since I’m not very familiar with its behavior during overclocking. My goal is for all four cores to reach around 4.5 or 4.6 ghz.
I disabled Turbo Boost and set the core ratio to 46, keeping other settings at their default values.
When I start up and open CPU-Z ROG, the multiplier shows x42 (8-46) and AiSuite3 reports a frequency of 4200 MHz. This doesn’t match what I expect when Turbo Boost is enabled.
So, can I still overclock without using Turbo Boost?
If the answer is no: how does it work regarding maximum frequency? I’d like to understand better.
My current stock speed is 4.2 ghz, turbo speed is 4.5 ghz but not per core, and if I push to 4.6 ghz, will it be a pure 4.6ghz across all cores or just an increase in Turbo frequency?
That would be my main concern.
Thanks in advance!
It might be a bios issue or the application isn't properly applying the changes when entering BIOS details. It could also be due to the CPU's stock settings being read incorrectly. The 7700k Kaby Lake processor and chipset are relatively new, so a bios bug is possible.
Keep turbo boost active and adjust the multiplier. It will start at a higher frequency based on the CPU's needs. That’s how turbo boost functions and it pairs well with overclocking. Why run at 4.6 or 4.7ghz when your computer isn’t busy? It reduces performance and slows things down when you launch games or tasks. What truly counts is the actual frequency. Certain applications may struggle to interpret data from specific motherboards, leading to incorrect core ratio readings. But if the frequency is correct, the issue lies elsewhere.
I understand, but let me clarify. Turbo boost actually increases the performance of all cores simultaneously, not just a few under load. You wanted every core to run at full speed regardless of workload, so disabling it would help achieve that. For instance, comparing doing nothing versus overclocking to 4.5 ghz with turbo enabled—do you want me to explain further?
speedstep and C-states behave as you described, but turbo boost simply increases the processor speed for all cores, possibly just a few of them. I’m not sure. I remember that when I overclock my motherboard, I set the core ratio to be identical across all cores so the frequency rises simultaneously. I can adjust it differently for individual cores, but I usually keep everything equal. In short, turbo boost helps the processor run faster as long as cooling stays within limits.
This was my worry, I didn't want turbo boost affecting all cores at once.
Why isn't the BIOS displaying the core ratio accurately?
It's still showing stock frequency, voltages, and multiplier, but only temperatures are changing.
I understand you addressed this, but the issue lies in the BIOS, not in the programs.
It might be a bios issue or the application isn't properly applying the changes when entering BIOS details. It could also be due to the CPU being relatively new, which sometimes causes such problems.
Yeah maybe..
I looked into the task manager and confirmed all cores were operating at full speed of 4.6 ghz during the stress test, which is exactly what I needed, thank you very much!
