Hey guys,
I'm really new to overclocking and I think I might have made a huge mistake.
I have an i7 6700k with a z170 SLI board and a h60 cooler. Usually I idle around 20°C.
In BIOS, my voltage is 1.28 at 4.4 GHz from OC'd the stock 4 GHz, but I can't reach 4.6 GHz on the stock voltage.
When I ran AIDA 64 Extreme to check stability at 4.4 GHz, my voltage went up to 1.35V under full load—does that sound normal?
My temperatures are also odd; sometimes they spike to 85°C for about two seconds. But is that a problem? Since 96% of the time the core 1 doesn’t exceed 75°C, and Core 2 averages 70°C, Core 3 is around 69°C, and Core 4 at 63°C, it seems manageable?
I haven’t changed the voltage in BIOS—it’s set to auto (default). Under load, it still uses 1.355V.
Should I be concerned?

Hey everyone,
I'm just starting out with overclocking and I think I've made a huge mistake.
I have an i7 6700k with a z170 SLI board and a h60 cooler. Usually I keep it idle around 20°C.
In BIOS my voltage is 1.28 at 4.4 GHz from OC'd the stock 4 GHz. I can't reach 4.6 GHz on the stock voltage.
When I ran AIDA 64 Extreme to check stability at 4.4 GHz, my voltage increased to 1.35V under full load. That seems normal? Also, my temperatures look odd sometimes, jumping up to 85°C for a couple of seconds. But is that something to be concerned about? Since 96% of the time the core 1 stays below 75°C, and core 2 averages around 70°C, core 3 is at 69°C, and core 4 at 59°C, it seems manageable. I haven't changed anything yet...

On Auto, adjusting the CPU voltage is typical. To achieve the highest performance, you'll need to set it yourself. It seems you could reach around 4.5 GHz with this approach. Voltages significantly influence power use and heat generation, so the temperature changes might be linked to the Auto voltage setting.

Sakkura:
On Auto, CPU voltage changes are normal. For the best overclock you'll need to adjust the voltage yourself. I believe you could reach around 4.5 GHz then. Voltages significantly influence power use and heat generation, so the temperature changes might also relate to the Auto setting. I appreciate your prompt response. It's tough to give an exact figure, but what voltage should I begin with? Also, I don't want to raise the voltage too much since I intend to use it long-term. What voltage would be best to maintain without greatly affecting its lifespan?

Consider beginning at around 1.3V, then gradually increase it to about 1.35V as needed. The exact adjustment should reflect how secure you feel while playing.

Sakkura suggests beginning at 1.3V and adjusting upward to around 1.35V based on safety preferences. They also mention experimenting with 4.5 ghz at 1.3v, which didn’t work well.

I personally wouldn't exceed 1.35v for daily sessions, though I think a 24/7 run at 1.35v could be acceptable given that 1.45v is also deemed safe. Consider testing the 4.5ghz at 1.35v first. If it holds up under stress, you might attempt 4.6, and even 4.7 if 4.6 succeeds. Just avoid running auto voltage during overclocking attempts.

If you're unable to achieve 4.5ghz at 1.35v, it might be related to your motherboard rather than the 6700k. Also, if you still struggle with 4.5ghz at 1.35v, lowering it to 1.4v could help you reach a stable overclock. Run a stress test at 4.5ghz to see if stability improves, then adjust the voltage slightly until you find the lowest stable point. You could even push to 4.6-4.7ghz at 1.4v, provided your temperatures stay safe and you're comfortable with the process.

It's unlikely you'll hit 4.8ghz without significantly increasing voltage, unless your board supports it. This process will require some time, but if you're serious about reaching 4.5ghz+, you can try. As I mentioned on my 6600k, I usually cap daily use at 1.35v, but even 1.4v is considered safe. It's up to you to decide how much you're willing to push your chip, but staying within 1.45v is a safer approach.

Monitoring temperatures during stress tests is crucial. I don't mind my CPU overheating above 60°C, except during gaming or regular use where it might rise to 80°C. Generally, I advise keeping the chip under 70°C during load for extended periods, though this is just my opinion and others may disagree. They often recommend not exceeding 80°C due to heat risks.

I also emphasize keeping an eye on your temperatures while testing. It's better to stay within the safe range than risk damage, especially if you're concerned about long-term chip health.

It might be okay to stick with the current 4.4 GHz overclock. If you managed to hit 4.5 GHz, that's a 2% speed boost. Reaching 4.6 GHz would be about a 4% increase. You probably won't notice the difference unless you run benchmarks.
My temps are within safe limits, but I wouldn't want to push them much higher. Voltages are fine, though – more voltage reduces CPU lifespan, so I'd avoid going even higher.

My temperatures are within safe limits, but I wouldn't want to push them higher.
Your voltages are fine, though; however, increasing them further could shorten the CPU's lifespan.
So this is unusual. I used offset instead of manual overclocking. Now it only needs 1.308V under load for two hours of AIDA64 at 4.5 GHz. But before that, I couldn't even hit 4.5 GHz with 1.35V manually?
