I wrapped my i5-7600k with the Gigabyte Z170-Gaming K3-CF.
Hello there. I was attempting some simple overclocking using online guides. I used the program: Intel Extreme Tuning Utility. The settings I configured were:
Processor Core Ratio: 46x multiplier (4.58GHz)
Processor Cache Ratio: 44x multiplier (4.38GHz) – I’ve been told to keep multipliers below 1x or 2x the core ratio
Core Voltage: 1.350V
My peak temperatures during stress tests reached 80°C. The issues are:
1. How should I adjust VCore (probably lower it) to improve performance and longevity?
* I attempted to reduce it to 1.30, but temperatures stayed the same, yet they increased more rapidly compared to my current 1.35 VCore. I also experimented with setting Default or around 1.20-1.25, which brought temperatures down to about 65°C (significantly better than 80°C, though I know that using Default is risky).
AND
2. If I wanted to raise the multiplier to 48x (4.78GHz) or even 50x (4.98GHz), what adjustments should I make to VCore and how should I verify the results? (For example, first lower it to 1.25VCore, then increment by 0.05 and repeat the stress test each time, finally picking the optimal setting).
* Honestly, I aim for at least 4.8-5.0GHz overclocked, but I won’t attempt it without assistance.
Please, provide clear instructions for these two concerns. If problem number 2 seems too risky for my machine, kindly help with problem number 1 – I’ve read I could easily reach 5.0GHz safely.
PS. My power supply is SilentiumPC Vero M1 600W 80Plus (SPC117) and I have 16 GB RAM DDR4.
The maximum overclock potential for an I5-7600K depends largely on obtaining a suitable chip. As of 1/13/17, the chances of achieving an overclock at a vcore near 1.4v vary across different percentages. The I5-7600K shows a range from 28% to 72% depending on the specific value tested. It is recommended to use the BIOS for adjustments, maintain all voltages in auto mode, and slowly increase the multiplier. Monitor the vcore and temperature during stress tests. The required vcore will rise as you push the limits. Ensure the temperature stays below 85°C under load, keeping the vcore at 1.4v for safety. Unless your hardware is subpar, you may reach safe thermal limits quickly, even with basic cooling solutions. Use adaptive voltage and speedstep to manage performance effectively.
The maximum overclock potential for this model depends largely on the quality of the chip you obtain.
As of 1/13/17, the chances of achieving an overclock at a vcore around 1.4v vary across different specifications.
For the I5-7600K, the percentages are: 5.1% for 28%, 5.0% for 52%, and 72% for 4.9%.
You should use the BIOS to make adjustments.
Maintain all voltages in auto mode and slowly increase the multiplier.
Monitor temperature and vcore during stress tests.
The higher the required vcore, the more cooling you'll need.
Ensure the operating temperature stays below 85°C, and keep the vcore at 1.4v for safety.
Unless your case or cooler is inadequate, you may quickly hit safe voltage limits even with a basic air cooler.
Use adaptive voltage and speedstep to lower multiplier and vcore when the CPU isn't under full load.
Track vcore using CPU-Z.
OCCT works well; Prime95 and IBT are less reliable.
Under regular use, you won’t reach stress test levels for extended periods.
Another question:
When I attempted to set my Ratio to 4.6GHz and VCore to Auto, it only required around 1.25V, but they suggest using 1.34V even though I currently have 4.2GHz. Why is more VCore considered advantageous? It seems counterintuitive since higher voltage typically increases temperature. Since running at 1.25V gave excellent performance (4.6GHz), what's the benefit of using significantly more voltage and raising the temperature? Is there a risk involved? Could someone clarify this or help me understand better?
