Is my overclocking within acceptable limits?
Is my overclocking within acceptable limits?
Hello, your current setup is stable but you're looking to push further. With the CPU at 4.7ghz and 1.25v, Prime95 stress tests show temperatures between 66-72°C and idle around 50°C. Deciding whether to continue depends on your tolerance for heat and performance goals.
You possess a solid motherboard that can handle an overclocked 3570K and the 3770K, which consumes more power because of Hyper-Threading. As long as you have a suitable Power Supply (PSU) and it stays below 1.3 Vcore and 80°C, you shouldn't face any issues.
It's not bad at all with temperatures well within the safe range and your voltage at a solid 1.25v... anything below 1.3v is fine and you can safely reach 1.35v; above that it's too much, though some suggest up to 1.4v. The main issue is your idle temps—50 degrees C is a bit high. I’d expect around 30 to 40 degrees C depending on your location, but 40 would be the maximum for idle... what cooler components are you using, like the case?
I cleaned the CPU fan after reading your text, and it's now between 32 and 39! I'm using a Corsair 12V DC 0.24 brushless fan. But even if my CPU can manage it, could other parts fail?

As vMax has previously highlighted, a value of 4.7 at 1.25 indicates a solid 3570K. To ensure clarity for fellow Forum participants and visiting readers regarding Core voltage, let’s examine this more closely:
vMax,
CPU Degradation remains a hotly debated issue among overclock enthusiasts striving to push performance further by another 100MHz. Opinions vary widely; particularly when some assertions seem less informed than others, merely echoing what a few have already stated.
Since Intel introduced 14 nanometer processors in 2015, many users are familiar with Vcore figures around 1.4 being discussed on platforms like gorilla poo in a cage. Those new to overclocking often lack the necessary background and experience, leading them to assume older 22 nanometer microarchitectures will handle the same voltage settings as their newer counterparts. This assumption is incorrect.
Not accurate.
Each microarchitecture has its own “Maximum Recommended Vcore.” It’s crucial to note that 22 nanometer 3rd and 4th generation chips won’t accept higher Core voltages than those of other architectures.
Here are the recommended Vcore limits for microarchitectures from 14 to 65 nanometers since 2006:
We understand that prolonged voltage and heat exposure can harm electronic components. When manually adjusting Vcore in BIOS, excessive core voltage and temperature can accelerate electromigration. Processors contain hundreds of millions of microscopic components; when these are stressed, fragile pathways and junctions degrade, leading to reduced overclock stability and performance.
Even if your initial overclock seems stable, degradation becomes noticeable later—often marked by more frequent blue-screen crashes that signal a gradual loss of consistency. The longer the excessive voltage and heat persist, the sooner transistor instability will set in. Reducing overclock and Vcore can temporarily restore stability and slow further wear.
Excessive overvoltage might cause immediate degradation, but a well-planned overclock can remain reliable for years.
Each microarchitecture also features a “Degradation Curve.” Generally, CPUs are more vulnerable to electromigration and degradation as they shrink in size. However, Intel’s 14 nanometer architecture, with its FinFET transistor advancements, offers better voltage tolerance.
The degradation curves align with the recommended Vcore values for 22nm 3rd and 4th generation chips, which differ from those of 14 to 10th generation models:
Degradation Curves relate to the term “Vt (voltage threshold)” expressed in millivolts. Monitoring Vt shifts is not possible directly. For overclocking and overvolting, Vt shift indicates a risk of permanent performance loss. Very high core voltages increase power consumption and temperatures, both accelerating Vt shift over time. Voltages that cause significant Vt shift should be avoided.
Core voltage multiplied by current equals power, which is influenced by workload and subsequently affects temperature. Over time, these factors contribute to transistor degradation due to electromigration and Vt shift.
Below are the key variables:
• Voltage
• Current
• Power
• Workload
• Temperature
• Time
These parameters aren’t just theoretical—they represent real degradation. Even if core temperatures stay within safe limits, applying too much Vcore can still lead to performance decline. The scientific evidence supporting this is clear; you can explore the hard data on electromigration and Vt shift through the provided links.
If you closely examine the Vt shift graph for 22nm processors, you’ll find that 1.325 volts is the safe upper limit. Yet, a practical guideline for 22nm 3rd and 4th generation chips is to stay below 1.3 volts or 80°C. I advise against disregarding this advice or blindly trusting your CPU’s lifespan based on unverified claims.
Keep overclocking within context. For instance, the jump from 4.5 GHz to 4.6 GHz represents less than a 2.3% increase, which barely affects overall system performance. Pushing beyond recommended core voltage and temperature isn’t worth it just to chase marginal gains.
Here’s the typical safe operating range for core temperature:
Temperatures above 85°C are discouraged.
Temperatures below 80°C are ideal.
You're right to consider safety while overclocking. It's good you're thinking about the limits of your components. Staying under 1.3v and 80°C helps protect everything. When boosting the CPU, other parts like the motherboard might also be affected. To find out how much your Asus P8Z77-V LX2 can handle, you should check its specifications and performance ratings.

I attempted to reach 4.8ghz but reached a limit of 1.3v, so I'm going to stay here, thank you a lot.
