i5 6600 non k overclock
i5 6600 non k overclock
So after my warranty ended, I upgraded myself with a solid AIO cooler and F5g BIOS to boost overclocking via BCLK. Everything was working smoothly until I reached 4.62 GHz @ 1.33 Vcore. Under AIDA64 the temperature stayed under 50°C after an hour of load.
My system specs are:
- Crucial 1x16GB DDR4-2400MHz
- i5-6600 non-k (140BCLK x 33 multiplier, memory set to 16x for BCLK down to rated 2400MHz)
- GTX 1050TI
- Gigabyte z170-HD3P
- Cooler Master Masterliquid lite 240
My concerns are clear: pushing it beyond this point requires a significant voltage increase. From forums I’ve read, safe voltages for daily use and gaming range between 1.35 to 1.38V. Experimenting with RAM timings, VRAM, RAM clocks, VCCIO, and VCCSA might help me push it further—possibly up to 4.8 or even 5.0 GHz. Should I upgrade my RAM if that’s the case? Also, does the RAM slot I use anymore matter in today’s build?
Update: I noticed CPU-Z displays different voltages than what BIOS reports. When I tried a stress test at 4.7GHz with 1.37V, it showed 1.36V. And at 1.335V it shows 1.32V. Should I keep this in mind?
Thanks for the help!
Turn on LLC (Load Line Calibration) to avoid voltage drop. Essential for high output capacity. Level 4-5 (50%) or above will handle the task. Turn off power saving as well. You're okay up to 1.40v.

Great. Keep it under 80c for regular use.
You shouldn't directly swap your current components with identical ones. Opt for a high-performance air cooler like the Noctua NH-D5S. Closed-loop AIO systems are not recommended as they often fail quickly, usually the pump. If you need them, choose an open-loop model despite the higher cost—it's a worthwhile investment. For media tasks, fast RAM is beneficial for handling large 4K videos and transcoding; simply add matching RAM to support dual-channel operation. A fast NVMe drive, such as the Samsung 970 Pro, can improve boot times, program loading speed, and save time during work.

RAM and CPU overclocking usually don't conflict. VCCSA/System Agent boost is required when adjusting BLCK. VCCIO handles RAM OC.
You can overclock the RAM directly. DRAM voltage remains stable up to 1.35v.
Unless you're using multiple RAM modules.

Appreciate the tip. Keep voltage below 80c for regular use.
Yeah, BCLK is quite strict about overclocking. I tried once, reached up to 167, then had to reset the BIOS because of all the constant tweaks.
Sorry, I didn’t mention this before. Most folks
reduce the RAM speed when BCLK starts overclocking it. Once they finish with BCLK, they begin raising the RAM clocks again. They also turn off the iGPU.
That’s odd. I thought about increasing both VCCSA and VCCIO.
When I want to experiment, I keep my stable overclock profile. Then I start trying different things—except for safety features like overvoltage protection.
Maybe. Most people can’t exceed 110.
You could stop working on it if you’re happy with your stable setting, or you could upgrade to a second-hand 6600k or better and skip the troubles. If you decide to go up, make sure it has a long return time to "torture test" like a drill sergeant.
