Yeah i've disabled it now.

Erm it's as listed in the starting post Offset +0.005v and Turbo Boost +0.004v

Pretty much followed as mentioned, although with CPU Load-Line Calibration i have it on Level 5 when i tried 2-3 i got 3.5+ as vcore where as on 5 it gets to 3.12 as max.

I did have it as 4.6ghz at one point via the built in overclock but it was getting to hot, so i might try a 4.5/4.6 and see how it is seeing as im doing it manually now.

This is with a H80 cooler although i am missing a few case fans as they stopped working and i haven't replaced which will reduce the temp as i've only got one at the front intake and the 2 attatched to the H80 currently.

I agree with Lucky, you probably have headroom to go up with the multiplier or down with the offset to bring temps down. Possibly (probably) both, as 1.000 is high for idle.

Also note: when you look at HWmonitor, it shows your highest VCore, which with LLC 5 is considerably higher than your loaded VCore, because LLC 5 provides you the most Vdroop. You should either look (while loaded) at the "Value" or check it in CPU-Z. It will only spike up to that 1.312 for a brief period when loading first occurs, and does not stay there long enough to heat up the chip to what a steady 1.312 would produce. My guess is you are probably hovering somewhere around 1.27 when under a constant full load.

I'll have another look at it tomorrow when i get a bit of time, i'll try both with the multiplier increase and lower offset.

Yeah it was hovering around 1.27/1.28 when under prime, it shot up once to 1.312 and never really went above 1.3 after that at all.

I think under LLC 3 it went up to 1.350 and was showing as that for a little while, didn't really like it that high and did LLC 2 which made it a bit lower and decided to stick with LLC 5 until i had more time to mess around with it.

Ok well your offset is fine where its at (.952 idle) so only increase turbo if Prime 95 fails with 45/46 multiplier.

Edit: If you idle is 1.00v then you can bring it down by switching to a negative offset

I have i7 3770K with AsRock Z68 Pro3 Gen3 board. I set it up to 4.4Ghz with 1.17V and it throttles under P95 or OCCT !! Why is that so ??

Well the question would be what is your cooling solution? What features do you have enabled speed step etc? What are you temps?

Several things will cause throttling temps is the main and the second would be drivers out of date or chipset not set.

what are your temps? Can you post bios screen shots of your settings?

Format Flash drive in FAT32, Reboot into bios, Press F12

Okay I haven't posted in here for awhile but since I decided to go from an Offset OC to a Fixed OC, I'm gonna need some help. I've included pictures of my BIOS settings and a 30 minute Prime95 run. I did run it for 4 hours and 9 minutes but failed to take a screenshot before it froze my PC. The temps are the same and there were no errors during the 4 hour run until it just froze the machine. Any feedback would be most welcome.

How elusive is 5ghz on a water cooled (switch h20-220 elite kit) system? I can get it to POST and boot into Win7, but no matter the voltage I throw at it or my RAM I fail P95 after 1 to 30 mins, and IBT just causes a full hang

Edit: I have a 3570k on a z77e6 board. I was able to hit 4.5 sub 90C on a 212 evo with .055v on turbo offset (hwmon said 1.268v vCore on load)

Some silicon likes going 5.0 more than others. A few things that might make it easier would be : enable PLL overvoltage (diable sleep state to avoid complications), using LLC 1, try raising and lowering VCCPLL. Also remember, the higher you go, the more voltage you need to hit the next multiplier, you might only need an extra .020 to go from 44x to 45x , but require .050 to go 49x to 50x. The colder that chip stays the better chance you have of hitting 5.0!

What type of voltage are you working with for this elusive 5.0? What is your "stable" daily overclock?

my daily on air was 4.5 @.055 turbo 1.76 pll llc 2

I'll try higher pll and llc with the 5.0 (thought I read less pll = more stability
