could someone check my readings and give some advice :)

image of readings during BF4

i have my i5 2500k set to 4.5 ghz at a fixed voltage of 1.35.

i have a few questions though. why does it read 4489.259 and not 4500. is this normal? also shouldnt bus be 100 and not 99.76?

and secondly using these figures can i set an offset voltage as opposed to fixed? also as it is fixed why do the minimums and maximums varie? shouldnt it be 1.35 no matter what?

thanks

it does drop slightly the bus speed,depends on the chip,you can set a 101 bclk

to use offset you have to find the right level of loadline calibration as that adds voltage to the cpu to counter vdroop (cpu voltage drop at load)

can try high loadline calibration and cpu offset of +0.020v

then see how close it is to 1.35v while your stressing cpu,if too low add one/two clicks more dvid,if too high reduce dvid by a few clicks

enable all powersaving/intel speedstep

Thanks for the tips i will have a look! Currently my llc is at level 3 out of 5 settings

Im new to this stuff but trying to be brave and have a go at it!

So far everyone has said to turn off powersaving stuff and speedstep? Any reason you suggest enabling it? I will take your advice ofcourse!

can keep it on level 3 llc

ive never had any trouble with keeping all powersaving on while overclocking,it lets the cpu downclock itself in speed and cpu voltage while idle,if stressed it switches to full speed/cpu v

Nice that sounds good, as long as it doesnt affect it under load then this sounds like a feature worth having on to me!

i switched on power saving and got a crash :3 will keep pplaying with it

might need bit more offset

could try +0.030v

Will give that a shot

just having another go so gone back to where i was. 4.5 with 1.35 fixed voltage. these readings are under load using prime95

am i right in thinking the offset is the difference from the VID under load to the CPU Vcore under load? so about -.040 here? if so i tried that and windows wouldnt boot

also prime 95 stopped working just after i took this screen shot though it ran for ages under these settings before
