Overclocked & Benchmark Intel 4790K @4.6Ghz at 1.2V
Overclocked & Benchmark Intel 4790K @4.6Ghz at 1.2V
Hi Friends
I recently upgraded my Intel Core i7-4790K to an overclocked configuration. I ran Intel Extreme Utility Bench, CPU-Z Benchmark, and Cinebench, and everything worked smoothly without any problems. I also increased the core voltage in the BIOS to 1.2, which helped keep the system stable at around 4.6Ghz. The settings were set to AUTO mode.
I’m curious if it’s feasible to lower the voltage further, as the Extreme Utility test showed a half-speed result and the PC restarted afterward. Also, is 1.2V sufficient for maintaining 4.6Ghz?
Additionally, my temperatures are within acceptable ranges at this frequency: maximum temperature reported by IEU is 77°C, while Cinebench shows 67°C.
Here’s a summary of my setup:
- Gigabyte H97-D3H BIOS v1.1
- Intel Core i7 4790K OC @4.6Ghz
- 16GB DDR3 1600MHz
- Corsair H100i V2 Liquid Cooler
- Aorus GeForce GTX1060 Xtreme Edition 6GB (Rev 2.0)
- BenQ 2270 - 1920x1080p
- PSU FSP Epsilon 600W, 80Plus certified
- Corsair Crystal 570X RGB case
Results from the tests:
- Intel Extreme Utility Bench
- CineBench
- CPU-Z Benchmark

Are you checking whether 1.191v is better than 1.2v? If yes, you're considering a very small difference of 0.009v that likely doesn't matter. It makes me think about whether your PC might struggle at 1.191v but could handle it at 1.2v, or even then it might not be enough. Run a full stress test using Prime95 without AVX or tools like Intel Burn Test or Asus RealBench for a few hours.
Are you wondering whether to use 1.191v or 1.2v? If yes, you're referring to a very small difference of 0.009v, which is negligible. It makes me think about whether your PC might struggle at 1.191v but perform well at 1.2v, and perhaps even at 1.2v it won’t be enough. I recommend stress testing your entire system for several hours using Prime95 without any AVX or similar tools like Intel Burn Test, Asus RealBench.
I’m also surprised that the system crashed at 1.191v but remained stable at 1.2V. When playing Assassin's Creed Origins at Ultra Settings, temperatures were between 58°C and 62°C. The game ran much smoother than before.
Other applications and software are now running faster than they did earlier.
I’m curious if I can push it even further to 4.7Ghz. I’ve heard that more overclocking requires more power. Does my PSU have enough capacity to support 4.7Ghz? Since the Aorus 1060 alone needs 400W, I want to know what stable voltage would be required for 4.7Ghz—higher voltages could cause more heat on the chip.
I’m new to overclocking and don’t have much experience. I usually just read different posts, views, and reviews.
Games won't show their true performance if your system isn't stable. Stress tests such as stability checks, prime95, RealBench, and Intel burn tests will help assess it. If your PC is stable as you claim, I'm happy with the current state as long as temperatures are acceptable.
Games may not reflect your system's stability accurately. Stress tests such as stability checks, prime95, RealBench, and Intel burn tests will help determine it. If your PC is stable according to your expectations, I’m happy with the current setup as long as temperatures are acceptable.
I’ve noted that the latest Prime95 version isn’t ideal for 4th generation processors. Please let me know which version would be best for your system. Because of timing constraints, I can only run a stress test with one software for an hour at a time—do you have something in mind?
So, which option would be more suitable for assessing your system’s stability?
If you were to perform just one test, I would use realbench. I tried other stress tests but they didn’t work. Realbecnh worked perfectly. Here’s the screenshot. Is it acceptable or should I run additional tests? Please let me know. My system remains very stable at both 4.5Ghz and 4.6Ghz.
This section serves as the reference point. Press the stress test button and then select your RAM capacity. A one-hour test should suffice, wouldn't you agree?
That’s the benchmark section. Press the stress test button then select your RAM capacity. An hour-long test should suffice, I believe.
Stress test failed after just five minutes with the same error—Blue Screen indicating Clock_Watchdog_Stop.
By the way, I recently swapped my motherboard to GA-H97-D3H; my old B85M-D3H is dead.
I didn’t upgrade Windows 10 or install a fresh OS. Just connected my HDD to the new motherboard and Windows 10 started up.
Is this the problem? Should I install Windows 10 again, or is there another step I need to take?
Also if you look at Real Bench Pic then you'll see it displaying red at the bottom of the picture saying "Unable to properly parse System Specs. Please report in RealBench Forum". The same issue occurs when using Intel Extreme Utility—benchmark passed but online comparisons return the same error. Is this a sign that you need to reinstall Windows 10 or something else?
