Fancy Overclocking in multiples of 0.5 instead of 1?

Shocked err... isn't it taking it a step too far? next one would be 0,25?

hmmm... not sure if its a necessary thing though it may take just a few cycles more out of your CPU....

I have to say I think it's a brilliant idea.
If you have a 3.0GHz CPU on a standard multiplier of 9 on a stock Vcore of 1.3. If your CPU (Extreme version only currently) allows you to change the multiplier by halfs you can achieve a more subtle overclock without hitting the temperature ceilings experienced by multiples of 1?

Example:

3.0GHz x 10 = a CPU speed of 3.3GHz probably with very little (if any) increase in Vcore?

3.0GHz x 11 = a CPU speed of 3.67GHz probably with a Vcore of 1.575 or higher. The temperatures you will hit on that increase exceed 70 degrees on a watercooled rig under full Prime load.

Remember all of the above is simply adjusting the CPU's multiplier and not the FSB. This is important because if you adjust the FSB this also changes the RAM FSB and will necessitate a need to alter many other timings and voltages. (Things start to get a lot tricker)

So with a 0.5 step in multiplier adjustment - allows a middle ground which from personal experience would be welcomed with big wide open arms Wink
It would allow a higher, simpler overclock?

Yeah, i suppose it just gives you that added amount of control of your system and lets you squezze the most performance outa it.

I understand that and accept that you get more out of your PC but what I meant (and in an enthusiast it is probably misplaced) is... in a a bordeline situation where you max out on a 10 multiplier and suddenly you have a 10,5 option... what is, in real life, the clock increase in CPU and RAM?
