What should I set the Turbo Boost Power Limit to be? Theres nothing mentioned in the guide about this particular power limit.
you can leave it on auto, your CPU wont use any more juice than it needs to

Mild overclocks are not really affected to any noticeable degree. If ASRock has changed something on the EXT4 and EXT6 boards or in the bios that would be great! However, you are the first person I have heard that claims that not all ext4's do it, so I am not holding my breath.
Check the official thread about wrong voltage readings.There are few guys that have +/- 0.002-3V .Some lucky bastards i guess,let's hope i'm one of them biggrin.gif

I'm using LLC level 3. In Cpu-Z this voltage is 1.384 but it is still very high? What's wrong? I'm using standard +0.004v on Turbo Boost Voltage and +0.005v on Vcore Offset on 4.5ghz. It works really well overall just played BF3 for 3 hours.

Well the +0.005 offset and +0.004 turbo is just a starting point but a +0.005 offset places you vcore too high. You will need to go into the negative offset and start bringing the vcore down. Most 2500k's will do 4.5ghz at around 1.30-1.32v maybe lower if you got a good chip.

What it the idle vcore displayed in CPU-z when its at a 16 multi?

Idle is 1.000V or either 1.008V. I've read somewhere that negative values shouldn't be used when overclocking. Also it performs really well right now is there any danger to life lenght of processor with my current vcore?

If I assume right I should put it on 1.384-1.320 = 64 so on -0.060V offset?

it is probably safe regarding degradation, but it seems to be overvolting slightly. Lucky is pointing out that yu can lower the offset (negative values are fine) to bring down the idle vcore. work you way into the negative values and test for 10-20 min according to the settings on pg 1. 1.384 is probably good for at least 46x.

There is nothing wrong w/ running a negative offset, a negative offset is your only option for decreasing your vcore since your at the lowest positive offset (+0.005). All you have to be careful of is that you idle vcore doesn’t get to low and become unstable.

My 2500k is running at 4.6ghz w/ a -0.010 offset and a +0.078 turbo. This puts my CPU at a 0.978 idle and 1.336-1.344v at full load

Running your CPU at 4.5ghz w/ 1.384v is most likely overvolting it.

Okay so I've been raising the multiplier and my last 5 min prime95 run was on 37 multiplier. I noticed in CPUz that the multiplier would fluctuate between 37 (mostly) and 36 (sometimes). Is this normal and okay?

EDIT: I'm on 38 multiplier now and on the CPU Z it shows the multiplier fluctuating between 36 and 38 where it stays on 37 or 36 alot of the time.

EDIT 2: I just did the 39 multiplier prime95 test and passed. I noticed something that I didn't know if it was okay. The VID on coretemp was varying alot sometimes getting as high as 1.290 and stuff and I haven't even touched the voltage turbo boost at all. Should it be varying like this?

yeah, there are going to be some smallish variations as loads change and as v droop sets in. How much variation?

Keep going with just the multiplier till it crashes...then start adding VCore!
