Min core value = max. Should I be worried?

[duyhx48]

Idk which setting it is but ever since I OC'd my I5-4690K to 4.3ghz, my min-core value keeps saying 4.3, that means its running my max-core all the time. Will the system be negatively affected in the long run? (by default Intel leaves it at 800Mhz min and 3.5Ghz max).

My cache CPU ratio is : 40

Also, the temp is rather high, 95oC while at full load 100%, I have a Hyper TX3 cooler. I am running vcore = 1.200 volt

Here are the screenshot of my cpu-z and hwmonitor:

2 questions:

1. How do I change the min core value to lower value? (when running idle)
2. How do I possibly reduce the temps a bit? I'm guessing reducing the vcore by 0.05 could help

*Update: just realized I disable "Intel SpeedStep" for OC purposes, that might be the answer for question 1 **

Did you turn off those power saving feature when overclocking?

Most of the time even if your cpu is running at 4.3 ghz, it does not produce much heat at idle. To reduce temp, you can either lower your frequency or voltage or get a more power cooler.

My mobo asrock z97 pro3 doesn't have that feature. Disabling "SpeedStep" might be the root cause as it doesn't allow the system to modify the frequency when being idle or at low usage. My 0% temp is about 42,43 so it isn't that bad.

For the temp: I might need to reduce the voltage to 1.15 and run Prime95 for a few hours and see if that helps

You can reduce temps by:
- Buying a more powerful CPU cooler
- Dropping the multiplier
- Reducing CPU LLC level
- Reducing CPU voltage offset to the minimum required to run the system stable at your core multiplier

Basicly check how much you can get out of your CPU using your current cooler( target 80-85 degrees max):
- Overclock in increments and never touch offset voltage until your system crash because of instability.
- If the max temp is not over 80-85 degrees then increase the multiplier by 1 step and repeat the steps.
- Keep note of the multiplier and offset voltage when you reach a stable OC per multiplier so you can dial back faster( or simply save the stable profile).
- CPU LLC is pretty aggressive on my ASRock Z77 extreme 4 at level 1 and too woobly on level 2 so I am forced to keep it at level 1 for stability sake, you mobo might have the same problem. If crashes occur try increasing the CPU LLC first before increasing offset voltage. Increase voltage only when CPU LLC is capped and keep an eye on the temps.
- This process can be pretty lengthy but the result is a set of OC profiles that are 100% stable.

Never use values that someone else posted, each system and component is different even if their reference is exactly the same.
