Hi

picked up a Corsaid H110i GT last week and have decided to have a go at overclocking even tho i had no plans too :/

i have got to 4.3ghz with 1.150 volts at the moment with temps maxing at 63C.

How high should i go on the volts? and is that high volts for 4.3ghz?

quite new to overclocking also.

thanks.
 
As a guide I have to use 1.27v for 4.5ghz & 1.38v for 4.8ghz

63c isn't of any great concern, when I had a H100i cooler mine tended to reach around 60-65c when gaming @ 4.5ghz

I'd have a play around & see what sort of temps you hit when running higher voltages.
Whats the airflow of your case like? plenty of fresh air coming in & do you have the H110 exhausting air out of the machine?
 
The normal advice is keep the temps under 80 at full load and volts under 1.4, i would just keep on going and see what your chip can do. Then for every day use just roll it back a little to keep the temps and noise down.
 
4.3 @ 1.150 volts is nice. Mine needs 1.215 @ 4.2.

You have plenty of room to play with voltage-wise and should be able to reach at least 4.5 @ 1.25v or under, if you want.

You may also want to experiment changing the orientation of the H100i fans, because all that intake and very little exhaust may be trapping hot air in longer than otherwise. You're bringing plenty of cool air in, but if the exhaust flow is not quick enough, the air inside will become hotter.
 
I run mine at 4.4 with 1.32volts can hit 4.6 with 1.39/1.4volts but not worth it.it really is pig of chip to get any decent speed.
carnt.t wait to upgrade to a better cpu.

This is a good guide, some points of note.

Running the uncore at default can help get a higher cpu clock with less volts vs overclocking the uncore

it seems overlocking the uncore barely adds performance and on some boards it's best to set the default numbered vale and not auto so 34x say if the cpu is 3.4ghz as stock

seems mainly to be about vcore and Input Voltage (aka VCCIN, Vrin, Eventual Input Voltage) I had to have mine at 2.0 volts and vcore at 1.35 for 4.5ghz and of course load line calibration

I'd use adaptive voltage too by changing voltage to normal and adding the correct + value so it's your default stock voltage + whatever you add this will downclock the voltage when windows downclocks the multiplier
