i7 6700k - 4.6ghz OC temps
i7 6700k - 4.6ghz OC temps
Hello,
I have a query regarding the temperatures of the i7 6700k after overclocking. I'm currently running an i7 6700k at 4.6 GHz with 1.305v (1.288v under heavy load), and the readings after 30 minutes of Prime95 26.6 are displayed in the attached picture.
The temperatures fall within a range of 65-70°C, with peaks reaching up to 74 degrees. *I'm using a Noctua NH-D15 with two fans.*
My memory is set to 3000Mhz @ 1.35v (1.10 VCCIO / 1.10 VCCSA).
The room temperature is around 27-28°C.
In the stock BIOS, temperatures are typically around a maximum of 55-56°C in Prime95.
I also have another question about the Adaptive mode on the MSI board. It seems to function well under high load since the voltage stays below the BIOS setting. However, when I reduce the load—such as during games—I notice the voltage spikes up to 1.34v. I'm unsure why this happens. I've tried changing the Override voltage mode, but it doesn't drop during idle, so I remain on Adaptive. (MSI Z170A GAMING M7 board with latest BIOS)
Play around with the settings. I’d probably spend a lot of time checking the forums on Asus ROG, where they cover everything from subtle to extreme OC changes and share various helpful tips. Based on what I’ve read there, I upgraded my i7-3770K to 4.9GHz stable at 1.32v and 74°C under p95 26.6 using a Kraken X61. The tweaks included turning off CPU and VRAM phases, setting the primary current to 255, and lowering the PLL from 1.8v to 1.7v—values most people would raise to 1.9v. Speedstep remained enabled, so it wasn’t a full-time OC. This suggests the processor could realistically reach 5.0–5.1GHz at under 1.45v, according to the batch numbers I found. I’d really appreciate your research on this...
Sunshine9511 is reaching out with a query regarding the temperatures of an i7 6700K processor after overclocking. They are currently running at 4.6 GHz with a voltage of 1.305V (1.288V under heavy load) and have observed temperatures after 30 minutes of Prime95 26.6, as shown in the attached picture. The readings fall within a normal range of 65-70 degrees, with peaks reaching up to 74 degrees. They are using a Noctua NH-D15 cooler with two fans, a memory clock of 3000Mhz at 1.35V (1.10 VCCIO / 1.10 VCCSA), and the room temperature is around 27-28°C. In the stock BIOS, temperatures are typically between 55-56°C during Prime95. They also mention an issue with the Adaptive mode on their MSI Z170A GAMING M7 board, where voltage spikes to 1.34V under light load, despite the BIOS setting a lower threshold. They suggest that the cooler is quite capable and recommend pushing it further if desired, but feel free to adjust based on preference. They conclude by saying anything below 95 degrees is acceptable. They believe laptop performance can indicate desktop capabilities. They mention not fully understanding the voltage problem and prefer sticking to manual settings on their Asus board.
I did adaptive for a short time just to observe the effects... I believed it would be beneficial, as the chip will consume power only as required!
The issue is that it often tries to increase voltage significantly, and I'm curious about the long-term impact on the chip... Urban's advice seems optimal... This allows you to provide extra power when needed, without an excessive amount that might damage the chip.

Karadjgne tried adjusting settings and found useful tips from the forums. Based on what I read, I optimized my i7-3770K to run at 4.9GHz stable with a temperature of 74°C under p95 26.6 using a Kraken X61. Small tweaks like disabling CPU and VRAM phases, setting primary current to 255, and lowering PLL from 1.8v to 1.7v helped. Speedstep stayed on, so it wasn’t a full overclock. This suggests the CPU could reach 5.0-5.1GHz at under 1.45v. I’m reaching out for more research since most verified world record speeds in recent years came from Asus boards. It makes sense they’d know about OC. Also, it’s advised not to exceed 1.4vcore on 6th and 7th generation CPUs.
Since OC is OC, it remains consistent across all motherboards regardless of brand. Although some names vary in each BIOS—such as VCCIO, system agent, VCCSA—the core functionality stays the same. The ROG OC community is vast and active, while MSI forums seem limited compared to what I experienced with my Mpower board. The i7-3770K is a third-generation chip, so it isn't affected by sixth-generation restrictions. The 1.45V voltage is the standard for this generation.
Karadjgne :
Because OC is OC. It's exactly the same on any motherboard, brand doesn't make any difference. Granted a few of the names are different in each bios like VCCIO, system agent, VCCSA etc, but the actual OC is just that.
And the ROG OC forum is extensive, huge, whereas MSI forums are pretty pathetic, I know, browsed them myself since I have an MSI Mpower board.
The i7-3770K is 3rd gen, so not that worried about 6th gen limitations as they don't apply. 1.45v is the 3rd gen limit.
Overclocking on all boards the same? No sir mr overclocking expert.
Alternatively, you can locate LLC within DigitAll Power. Select LLC and position it in the middle level 4 or 5 area would suffice. The configuration below DigitAll Power (not inside) will be related to the CPU core/GT Voltage Mode. Choose that option and adjust it to Adaptive+Offsetmode.
