You'll see my build in my sig
At the moment I run my processor @4.2 GHz, and I've only notched the ratio up that little extra ontop of BIOS own overclock setting when running the Asus Optimized-profile inside BIOS - which clocks the processor cores to 4.1/4.1/4.0/4.0/4.0/4.0 GHz.
What's interesting is that BIOS don't use any static voltage setting, but has an adaptive curve that changes the voltage by the needs of the CPU, so that it's lower when not needing much, but higher when the CPU has to work harder, to a maximum of 1175 mV.
- Am I right in suggesting that this may reduce the wear and tear on the CPU, especially if I were to overvolt the CPU - as te higher voltage is only used during heavy load, and is backed down towards stock voltage while light work (surfing, office work etc). So in my case I would be at stock voltages maybe 70% of the time while working, but still be able to get that extra juice when gaming or running heavy applications when needed.
Of course it's suggested on many places that it's much more safe to overvolt these days' high end consumer CPU's as long as you have the necessary cooling, and that you shouldn't be too anxious about it as long as you've done your research and takes overvolting phase in a calm tempo. But perhaps using this adaptive voltage setting reduces the wear and tear even further?
Elsewhere there was a dude suggesting that this adaptive setting might be more harmful than setting a static overvoltage as the differencies in voltage and temperature caused by the curve, may wear and tear the material even more - however luckily I'm the son of a man with a PhD in physical chemistry active in the material branch for 25 years, and of course I asked him, and he stated that it takes much higher and much more frequent shifts in voltage and heat to become a problem - if for instance the tempearute would go from 40C -> 80-100C several times within an hour all day we would have a problem, but go between 40C -> 60-70 only a few times towards the evening there wouldn't be any problem. And isn't this what a CPU is built to handle? All those billions per second of voltage (and surely temperature also) shifts in the transistors as well as in the other parts in the CPU.
- Is there any risk that the overclock setting gets unstable because of the curve - for instance that I've found the right voltage at 100% usage during a stresstest, but when the usage goes down to 90 (lighter stresstest) or 75% (heavy usage) the voltage according to the graph isn't optimal anymore and I get bluescreen? Or can I expect that if the voltage works at 100% I can expect the graph to still have a good voltage setting at the lower usages? Note that this curve is not linear, but seem to have been more custom made to match the different needs at different level - I've screenshoted the graph... note that this may be screenshoted inside AI Suite 3 but it only shows what BIOS already have setup.
- In conclusion, would you recommend that I use a static voltage setting that is run all the time, or that I instead adjust the graph already active so it reaches higher as I increase the clock ratio? And why?
Here are the pros and cons of adaptive vs static as far as I'm thinking right now (some will probably be wrong):
PROS
- Adaptive: You're at the stock voltage most of the times despite overvolting, meaning the overvolting has its impact reduced as it's not used all the time
- Adaptive: Heat is decreased when CPU isn't used heavily as the voltage goes down, giving quieter performance from the PC as a whole
- Static: More used and there are more references to different overclock/overvolt settings, so the results are easier to expect
CONS
- Adaptive: The settings get less fixed and more dynamic, giving more room for some error (at least if I edit the settings poorly)
- Adaptive: IF I were wrong - may cause more stress to the material because of shifts in voltage and temperature (unlikely imo)
- Static: Unnecessary voltage settings at times (for instance 1.3 V during light tasks, when it really doesn't need it)
