6800k - Fist time overclocker
6800k - Fist time overclocker
Hello there.
I recently assembled my X99 setup, balancing roughly half gaming and half workstation use.
Here’s what I have:
- NZXT H440 case
- Asus X99A-II
- Intel i7 6800K processor
- Corsair H100i v2
- Asus GTX 1070 Strix OC 8G
- 32GB 4X8 Corsair Vegeance LED
- M.2 SM961 512GB (for boot and essentials)
- Samsung 500GB 850 Evo (mainly for games)
- 2TB Seagate for large files and media
I’m quite nervous about overclocking because there are so many details to grasp, and I feel completely uncertain. My build is well-cooled thanks to three 120mm fans at the front, two more near the radiator, and a 140m exhaust fan beside my AIO for the 6800K. That gives me plenty of space to keep things running smoothly.
My challenge is that I’m not confident and my first try ended in failure. I attempted to push the 6800K up to 4.2GHz using around 1.275V, but it didn’t work out.
Could anyone share their experience with Asus X99 and overclocking the 6800K? I’m hoping to reach at least 4GHz to match a 6700K in single-core speed and aim for strong multi-thread performance since each clock runs near 4GHz.
Please be kind and gentle with my questions—I’m still learning the terminology and process.
Thank you very much for your help.

Consider testing at 4.2 ghz with 1.35 voltage. It might help to run a stress test for about four hours to check stability. It could be necessary to increase the voltage further. I'm uncertain if my previous adjustments were accurate, so I'll try 1.35 if I'm sure about the overall settings. I currently have Prime95 for stress testing; do you know of any alternatives you'd suggest? If I achieve a successful overclock, I plan to extend the stress test to six hours, some recommend twelve or even twenty-four hours.
I made these changes: core clocks same, 42 multiplier, CPU voltage 1.275, changed 102 to 100.
Windows managed to start at 4.2 with 1.25V
It stopped with 4.2 at 1.225 after another site reported success at 1.22V

Windows successfully loaded 4.2 @ 1.25V
It stopped working with 4.2 @ 1.225 (after another site reported success at 1.22V)
Consider increasing voltage to 1.35V for a 4.2ghz and let me know the outcome
Planning a break today. I plan to adjust a 4.0Ghz OC that was stable in Prime95 at 1.225V for a while before it crashed after changing settings to 1.23 and 1.24 to reach stability at 4.0Ghz. Not sure what’s happening, but I’ll attempt again tomorrow.
First, I need a reliable 4.0Ghz setup then move to 4.2. This appears to be the most viable path right now. Instead of diving in immediately.
SpencerGoshorn shared their experience with the system performance at different voltages. They noted stability issues when using 4.2 at 1.25V and a crash at 1.225V, suggesting adjustments might be needed. They also mentioned testing 4.2 at 1.35V and observed some improvement around 60 degrees.
When attempting to turn on XMP, my overclock crashes. It's unclear what's happening. Could the problem be related to my 2666mhz RAM? I've heard that BCLK should be adjusted to match the CPU and RAM ratios, but it remains at 100 mhz. Should I set a BCLK ratio that matches my CPU multiplier with my RAM?
I'm having trouble accessing BIOS because my keyboard stopped working when I tried to enter it. I recently completed a stress test at 4.2 with 1.3V, but now I'm unsure what caused this issue. The keyboard and mouse are connected via USB 2.0 ports, yet they don't function after restarting, and pressing F2/Del doesn't get me into BIOS.
