Running my CPU 24/7 stable @ 4.5ghz with 1.320.

That was the best voltage i could do for a 4.5.

As for 4.4 the best voltage was 1.265.

I like overclocking so im very happy with my 4.5 along with my GTX 980 @ 1490clock speed.

Power plan is balanced and cooler is the corsair h100i.

Thanks.

So if i revert back to 4.4 ... is it good for gaming ? I mean is there a difference in gaming between 4.4 and 4.5 ?

There comes a point in overclocking when a small increase in clock speed requires a big increase in voltage. This is the overclocking wall.

A common misconception is that high voltage damages the CPU, but it's actually the associated increase in heat which does that. In theory, you could allocate as much voltage as you want and everything will be fine providing you keep the temperature in check. This is how people achieve insane overclocks by using liquid nitrogen. Obviously in the real-world, things are very different.

Like Wisecracker said, a 100Mhz increase won't get you any tangible improvement. You're looking at a performance increase in the miliseconds.

" ... Section 8 - Overclocking and Vcore

Overclocked processors can reach up to 150% of their Thermal Design Power (TDP) when using manual Core voltage (Vcore) settings, so high-end air or liquid cooling is critical. Every processor is unique in it's overclocking potential, voltage tolerance and thermal behavior.

Regardless, excessive Vcore and temperatures will result in accelerated "Electromigration" - https://www.google.com/?gws_rd=ssl#q=Electromigration - which prematurely erodes the traces and junctions within the processor's layers and nano-circuits. This will eventually result in blue-screen crashes, which will become increasingly frequent over time.

CPU's become more susceptible to Electromigration with each Die-shrink, so 22 Nanometer architecture is less tolerant of over-volting. Nevertheless, Vcore settings should not exceed the following:

-> Core 2

1st. Generation 65 Nanometer ... 1.50 Vcore
2nd Generation 45 Nanometer ... 1.40 Vcore

-> Core i

1st. Generation 45 Nanometer ... 1.40 Vcore
2nd Generation 32 Nanometer ... 1.35 Vcore
3rd Generation 22 Nanometer ... 1.30 Vcore
4th Generation 22 Nanometer ... 1.30 Vcore

When tweaking your processor near it's highest overclock, keep in mind that for an increase of 100 MHz, a corresponding increase of approximately 40 to 50 millivolts (0.040 to 0.050) is required ..."

Hope this helps,
