Is it safe to use a 6800k processor with 4.2ghz and 1.31v voltage under 66c?
Is it safe to use a 6800k processor with 4.2ghz and 1.31v voltage under 66c?
Hi,
I hope this helps.
I’m testing my first original character and have a few questions.
My system runs at 6800k, currently at 4.2 with Manual 1.31v and solid stability. I can manage 4.1 at 1.276v without issues—definitely a big jump.
How much will high voltage running affect my CPU? Will it fail after two months of constant use? Is 1.31k safe?
Also, what’s the impact on performance if I lower it to 1.276k by just 1mhz?
Lastly, regarding the modes—my Asus motherboard offers Adaptive, Manual, Offset, or Auto. Which should I pick? And should I keep Turbo enabled in the advanced settings?
Thanks!
Also worth mentioning is that I think I might have missed the mark in the silicon draw. This setup isn't stable when it drops below 1.3 at frequencies over 4.1ghz. I'm running on an H100i.
Adaptive voltage works reliably. But during stress tests, manual control is better. Adaptive can cause unusual behavior with tools like prime95. 1.31 should be fine, though any overvoltage will speed up CPU wear. Real-world degradation would be limited to about 12 to 10 years of use.
Hmm thanks,
When I set the voltage to adaptive, it doesn't seem to go lower on Idle, only higher on load!Is that just the weird behaviour you mentioned?
This is a video editing PC, surely when I render it will re-create these stress-test conditions?
(p.s. sorry about the swearing, and thank you for your help!)

No fortunately that's not what I mean.
😀
Let me break it down to you:
Manual Voltage:
Sets a manually applied voltage and NEVER goes down no matter what. Excellent for stress testing, terrible for power savings.
Offset Voltage:
Adjusts ALL voltage points by however much you put into your CPU. So say you have a stock voltage of 1.100v, and you add an offset of +0.200v. When the CPU is at idle voltage, medium voltage (1400-2500mhz range), and max voltage (when operating at max clock speed), the mobo will apply an additional .200v to all those voltage parameters.
Adaptive Voltage:
Adaptive is the best energy preserving voltage control we have today. When manually adding an adaptive voltage, the adaptive voltage
only works when the CPU is at max turbo frequency
. So when your at low or medium voltages, those remain at their default voltages.
HOWEVER, because of how unrealistic stress testing loads up a CPU, adaptive voltage can very possibly add
too much voltage
to your CPU duing stress tests. This is why it's always recommended to use manual for stress testing, then going to adaptive when your done with that.
Stress testers like Prime95 put a very unrealistic load on the CPU, no other non-stress testing programs on earth can possibly do this.
Just a quick note about the blue screen from Realbench (still in manual mode). How about 1.32?
When you mention 'default voltages' during low turbo performance, it refers to voltages being configured to their original factory values. So I plan to return to 3.4ghz when idle? And then, when I activate turbo, the voltage will rise significantly to around 1.32?
Running a render test now. With turbo boost turned off (through windows, High Performance mode) and CPU at 4.2ghz consistently. I render significantly faster in After Effects.
With Turbo boost active and Balanced power mode, the cores seldom reach 4.2 and rendering slows down.
Is this just changing modes when I need to render? Is there a way to activate Turbo more often? Perhaps disabling turbo in the BIOS and using Balanced instead?
*EDIT* The previous attempt didn't succeed; I ended up at around 3.4ghz overall.
TechyInAZ :
Corrected message.
But here are typical idle clock speeds for Intel:
Idle ≈ 700mhz
Mid ≈ 1400-2500mhz
High = Stock clock speed
Max = Overclocked clock speed
It appears the distinction between Balanced and High Performance settings is quite noticeable. I’d like it to activate more frequently. Is there any option to make it disregard the stock clock? Currently, it looks like this:
Balanced mode
*Idle* 1200 MHz
*Start Render* 3400 MHz (Stock)
*Occasional points in the render* Cores 2 and 3, 4200 MHz briefly.
= Slow renders
High Power Mode
*Idle* 4200 MHz but low temperatures/low usage in Task Manager.
*Start Render* 4200 MHz
= Much quicker renders.
