I7 6900K overclock
I7 6900K overclock
Hello friends,
My name is Samuel and I’m looking to boost my CPU performance to 4.2Ghz.
I have no prior experience, so if you can assist me, that would be a huge help.
If you’d like to understand my system better, here are the details:
- Motherboard: Gigabyte X99 Ultra Gaming
- CPU: I7-6900K
- Cooler: Corsair Hydro H115i
- Graphics: 2 SLI Aorus GTX1080TI Waterforce Xtreme Edition cards, 11GB each
- RAM: 128 GB at 3466Mhz Corsair Domino Platinum
- Power supply: Thermaltake modular, 1475W
- Storage: 3 Samsung SSDs totaling 5 TB (2+2+1)
I also have an LG LED IPS monitor, 38 inches, 3840x1600 resolution.
My current CPU speed is 4.0Ghz.
Could you guide me through the process of increasing it to 4.2Ghz step by step?
Thank you very much for your help.
Samuel F.
I would begin by opening your bios and adjusting the CPU multiplier to 42 to test the boot process. It might start without further modifications. If it boots successfully, proceed with a stress test or benchmark to evaluate stability and temperature performance. Cinebench is a widely used benchmark for this purpose.
If the system remains unstable or fails to boot into Windows, refer to the provided video tutorial on overclocking for guidance.
Hi,
Thank you for your message. I really appreciate your support.
I followed the instructions and set my CPU to 4.2. My computer started without any issues.
The Cinebench R15 test, focusing only on the CPU, returned a score of 1748 cb.
Is that acceptable?
Additionally, I checked the voltage and it's 1.271.
Hi Samuel,
The initial goal of overclocking is to determine the lowest voltage needed for a specific frequency to maintain stability.
Start by recording your current frequency and the voltage you observe during a stress test in manual mode within your BIOS.
You can then proceed with two approaches:
1°/ Improved performance:
Using the original voltage, increase the multiplier until stability is lost, then adjust the voltage slightly (increments of 0.025-0.05V) and continue.
After achieving the desired stable frequency, reduce the voltage as much as possible while keeping it stable.
2°/ Enhanced thermal management:
Maintain the original frequency and lower the voltage to the extent possible until stability is lost.
Once finished, you can reactivate power-saving features such as C-States and set the voltage to adaptive, allowing it to adjust with load conditions.
Tips: Keep the voltage below 1.35-1.38V and maintain a temperature of around 85°C during testing for regular use.

Hello,
Thank you for your message. Your support means a lot to me.
I followed the instructions and adjusted my CPU to 4.2. The computer started up without issues.
I ran the Cinebench R15 test focusing only on the CPU, and it returned a score of 1748 cb.

Also, I checked the voltage settings and it’s currently at 1.271 volts.
The results seem correct. If you changed the multiplier to 42, your motherboard would be using the stock voltage, which is fine.
1.271 volts appears reasonable. I agree with rodolphe.viard; I wouldn’t exceed 1.35 volts and you’re aiming for temperatures below 85°C.
I prefer keeping my average load temps under 80°C for regular use.
You might try 4.3 or higher. If you encounter a blue screen, increase the voltage gradually by 0.01V until it stabilizes at 4.3.
If you reach 1.35 and still see crashes, revert to the last stable frequency.
Please keep an eye on your temperatures—high heat can damage the CPU, especially with a 6900k that’s not inexpensive.
Intel XTU is a good choice for monitoring CPU temperatures.
Thank you for your feedback.
My CPU is set to 4.2 with a voltage of 1.271.
The Aida Extreme Test showed stable performance, with temperatures reaching a maximum of 65°C per package and 73°C per core.
In my room the temperature is around 27°C.
Is this acceptable?
Regarding overclocking, I have an Intel i7 6900K. At 4.2 it should be fine, but I'm unsure if increasing it slightly to 4.3 would cause damage.
Also, I've set my RAM to 3000 MHz, though they can go up to 3466 MHz.
Thank you.
I'm unsure about the exact performance increase of the 6900k. Each chip varies, with a base clock of 3.2 and a maximum turbo speed of 3.7ghz. That means a 4.2 boost is already over 10% above the turbo limit. You shouldn't risk damaging your CPU unless you apply excessive voltage or it overheats. Excess heat often comes from too much voltage.
A sensible guideline is to keep voltages below 1.35 and maintain average temperatures under 80°C.
Thanks for your support and for clarifying your questions.
After multiple tests and using Firestrike, the CPU score gap between 4.0 and 4.2 wasn't significant.
At 4.0 it was 20.700, and at 4.2 it was 21.600.
It doesn’t seem justified to stress my CPU by such a large margin.
I decided to keep it at 4.0.
Anyway, I’m thinking about upgrading to the I9 7980XE.
Thanks again, everyone.
I use Flight Simulator Prepar3D V4.2 because it's the first reason. Another reason is my desire to achieve the highest scores, possibly due to the significant investment of over 8000 Euros in building this system. I just want it to keep improving and upgrading since 2014...
