2500k overclocking help

[Calarahil]

After watching TTL's video on overclocking I decided to give overclocking a 2nd try because before I was a bit confused on how things worked and his video really helped shed some light on things. So props to you kind sir from across the pond.

My question comes into question with offset versus fixed. I believe in the video he is using fixed as I'm unable to manually set my voltages other then to move my multipliers to my knowledge in offset. What is optimal for me to do. I would like to have it setup so that its at a low voltage when I'm idle doing nothing and by the same token my CPU frequency to be low and then when I get in a game for it to crawl up to 4.2-4.5 ghz. Now I've seen this work just fine with the AUTO overclock deal that my board has but as overclocking people have nailed in deep is that the voltages go all over the place with auto and you normally have voltages that are higher then if you were to go in and find the voltages to yourself. I've played with fixed quite a bit with the voltages and I was on the lowest setting on my h100 hitting around 75-76 degrees Centigrade by pushing my fan speed up through the controller I was able to get more decent temps but that is what I was getting at the setting I was at. I will provide a couple of images and my specifications for referencing purposes. TTL said to come to the forums if we had questions I have faith that the community here can point me in the right direction.

Also, when I was using OCCT and CPU-Z my tests would fail pretty quickly hitting 80 C with offset just by moving the multipliers am I doing something wrong with that?

I also used this as a guide on top of what TTL had provided in his video I'm unsure if these things are good advice or not.

Moved to correct forum.

thank you kind sir! I noticed that I had placed it within the graphics overclocking my mistake.

while overclocking using a voltage offset will give you reduced power consumption under light workloads, you also have to consider that your top-end performance may become somewhat erratic, or your light load/idle state may lose too much voltage. Your best bet really is to set your voltages manually in my opinion since you will know precisely what your computer is doing when it's doing it.

Would it hurt my computer though to be running at the 100% speed all the time without turbo?

 

[Josh Weston]

In my opinion, no. My computer is left overclocked at 4.4GHz 24/7 a day at 100% load - no performance degradation as of yet, and it's been nearly a year.
It will however yield higher idle temperatures compared to something using SpeedStep and Turbo to achieve powersaving/extra performance when needed.

I was more afraid of the chip having a significant shorter life span running at full blast all the time

 

[Josh Weston]

Not from what i've seen. In the long term, yes, it's probably more damaging to your chip than letting it downvolt/clock itself when it's not being used. I wouldn't say a significantly shorter lifespan though. A lot, probably the majority, of users on here that overclock use the fixed voltage, full clock method.

 

[Calarahil]

I thought as much. Given the videos and guides I've seen from others just wish offset was as straight forward as fixed.
