What were you looking to get out of your chip?

I don't use that automatic setting myself except in the beginning when I get a new motherboard just to test it out for some basic low level stability check. I overclock the CPU manually and feed it the minimum stable voltage. I wanted to run my chip at 4.2GHz for 24x7 it's a 5930K so I set the multiplier to the setting to get me closest to it and using 125 base clock (bclk). I started with 1.3v and slowly lowered it until I got to the voltage where I would get BSOD and then increased it slowly until I get a stable OC at around 4.2GHz. The problem with using the performance setting is that it wants to feed your CPU with too much voltage, it's decent but my 2 cents it's not that best way to OC. By the way for my cache I start with stock voltage and OC until I get the CPU to where I want it stable then I work on the cache.

I have cstates disabled because I didn't want to save the electricity to sacrifice my OC stability. Anytime you have VT or some type of power saving it seems to always interfere with OC. The only thing I can say about SSD is don't set anything to allow the machine to constantly write to it like some defragging software, etc. The less you change the bit state the longer it will last.

I hope this helps you somewhat but there is a lot of methods and tricks for overclocking and if you really want to squeeze all the juice that you can out of your CPU I suggest joining the haswell OC forum, there is a ton of smart guys in there that can give you more detailed tips and a lot more experience.

All of our VSIDs are in the 0.8s and 0.9s. We have to up that voltage to 1.2 and 1.3 to get overclocks around 4.4 and above. That's a significant percentage difference in core voltage from stock. Therefore, wouldn't it stand to reason that running it at the constant 1.2-1.3V would lead to chip degradation over time versus dynamic voltage? Or are you suggesting that the difference is negligible?

Also, when you are referring to "performance" setting, you are referring to letting the motherboard OC for you and automate the voltages, correct? (As opposed to the high performance setting in Windows or other similar ones in the BIOS.)

It really depends on what you want to do with your chip but for fun I OCed my chip to 4.6-4.7GHz stable and ran it for a while but it took more voltage than what I wanted to feed it 24x7, I think around 1.35 if I remember correctly, I'm happy with the current 4.2GHz. The question is what are you going to be happy with smile.gif. Dynamic voltage with minimal OC is good if you want your chip to last for 10 years and use up the least amount of electricity. By the way I have seen chips OC higher when it is brand new and then settle down lower to a max stable OC.

That would suggest that dynamic voltage would be helpful, then. FYI, I'm at 1.23V on air to get stable 4.6GHz, but I've decided to go to 1.18V which is needed for 4.5GHz. Temperatures are in the mid 70s, except for the CPU Package temperature that others have mentioned and no one can explain. Still, I'd like the voltage to lower when I'm not using the CPU at full bore for the reasons you mentioned.

Let me do some tests and let you know what I come up with but basically you want minimum voltage used until your computer demands the processing power then you want it to hit the ceiling that you set to get it. By the way which CPU are you using with this motherboard?

I am using a 5930K, and apparently have a very cooperative chip - all the more reason to make it last. That's why I am curious how to get the overclock voltages to kick in when I'm under load, and drop down when I'm not. But I haven't been able to get an answer out of anyone. Even returning to stock voltage when not under load would be beneficial, though the lower the better.

On my phone on this post. One important thing about voltage on the CPU. Even if your voltage is at 1.2v for example that does not mean necessarily mean your CPU is draining massive amounts of current and adding to your CPU degradation and power usage until you actually put a load on it. You can see this clearly if you put a watt meter on your computer and do some tests. Voltage just means it's available but not necessarily getting used. I'll reply to the post once I get back to my computer

I'm not sure that's how the degradation works, at least as far as the effects of voltage are concerned (for the effect of heat cycles, I would agree with you). Voltage is potential, and the higher the voltage the more likely a piece of current, no matter the size, is to jump across an insulating material. So even if the computer is not utilizing the full amperage (and power), the voltage can still cause issues. Perhaps higher current can exacerbate the damage done if the insulating material is jumped, but a high voltage still contributes as far as I know.

At the risk of getting called nerd here it is. I actually have an electronics engineering degree and know a little about how voltage and current works smile.gif

Current vs Voltage:
When you measure voltage across a battery let's say you are getting 5v but without a load that does not mean you are wasting energy you just know it's there. To put it more in simpler terms think of a water dam. You have a small pipe and when you measure it you can see that the water can run 5 cups per second, you know it can go that fast but

Voltage is potential, and the higher the voltage the more likely a piece of current, no matter the size, is to jump across an insulating material. So even if the computer is not utilizing the full amperage (and power), the voltage can still cause issues. Perhaps higher current can exacerbate the damage done if the insulating material is jumped, but a high voltage still contributes as far as I know.

Yes, you have a nice performing 5930K congrats! smile.gif

To put it more in simpler terms think of a water dam. You have a small pipe and when you measure it you can see that the water can run 5 cups per second, you know it can go that fast but that's just one pipe. When you need to use a ton of water you would need a billion of these pipes and that would increase the current. If you look at the temperature of the CPU while it is idle you will see that it is much lower because there is only one path that electricity is flowing to put it in the simplest terms. Yes I know, slowing down the amount of water leaking from that single pipe will reduce the amount of water but 1 pipe out of 2.6 billion leaking water is not that bad except for the durability of that single channel. These pipes translate into the number of transistors in a 5930K CPU (accuracy check is encouraged!).

Freqency vs Load.
Just because the frequency on your CPU is going 4.6GHz that does not mean all your transistors are busy doing 4.6GHz worth of work but you know there are some that are doing work that's why it's advantageous to lower the frequency lower if you could while it is idle but it's not as bad as it seems. Your chip's wear and tear is not getting wrecked until you put in a load on it. Unless your CPU is processing massive instructions while it is idle it's not that scary.

I'll see if I can get adaptive voltage and lower frequency to work on the Sabertooth X99 with a high OC. I'll let you know if I find a sweet spot of what needs to be set and let me know if you figure it out first smile.gif

While it is possible my understanding is incorrect here, I want to reiterate that I am not confusing the presence of a voltage with the presence of a load (current). I understand that voltage does not mean load is present. But what you suggest means I could apply 300V to the CPU and as long as I don't put but a minimal current through it, no damage will be done, and that makes no sense to me. Insulating materials are rated for a specific voltage before the material no longer functions as intended (see a capacitor, for example). Are suggesting that CPUs operate differently, or simply that during low current the damage done by the higher voltage is negligible? Those are two different things. The latter I can understand, but the former is highly counter-intuitive.

Edit:
As for the dynamic voltage, with implementing it was assuming the frequency would change with it to help out with going easy on the chip, which presumably means the multiplier is dynamic as well. I don't know which cstate and power options are needed to be changed in the BIOS to achieve this, so I don't even know where to start. Those specific options in the BIOS are the least descriptive. That Haswell overclocking guide is also cryptic. I know I set things in the BIOS to take off power saving for the purpose of finding the maximum overclock, but which of those settings is needed for the overclock and which is needed for dynamic voltage/frequency is not exactly clear to me. The same goes for settings in Windows.
