I found it stable with vcore at 1.360 @ 4.6ghz and now I am preparing to clock it higher to 4.8ghz. Problem is I dont exactly understand few of settings in my Mobo. Could u guys explain to me how LLC works in general. Then Internal PLL overvoltage and also PLL voltage values (lower/higher) - what does it do? I found that at 4.8ghz I will need around 1.450~ Vcore or more. It is really confusing and I feel like there is not enough information on the internet or either I'm a total noob at searching rolleyes.gif Thanks for your help guys , really great forum smile.gif [Disclaimer: I have read the guide here but there is not enough information. For instance on PLL voltage values etc]

It's just I have 15 C degress headroom as at 4.6 i get around 70C. Would really love to use that little more power smile.gif

Also my idle voltage at 4.6ghz is 0.952v Is that ok? Can u actually have too low voltage for 1.6ghz?

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?

Hey man dont worry. VID is just showing u how much voltage CPU is asking for, it is not Vcore at all, you can monitor Vcore with other program like HWmonitor or CPU-Z.

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

I'm idling now and my CPU Z read out is that I'm at around .970 V on average for core voltage. However on my core temp VID readout, I"m geting 1.2360 or slightly higher sometimes but never as low as what CPU Z is saying.

Also is it normal when using the standard settings from the guide to not have your multiplier drop to 16 or something when idling? Mine seems to stay at 41 constantly right now.

EDIT: on CPU Z my core voltage under load is varying between 1.15 and 1.2 volts. On Core Temp my VID is varying between 1.25 and 1.29 volts

You should be dropping to 1.6ghz if using guide. Check if Enhanced Halt State (C1E) is Enabled and also Intel SpeedStep Tech. Both should be enabled and both make u stay at 1.6ghz at idle

It is actually in C states in guide here:
Quote:
So heres your 2 options:

Offset Mode: Your CPU will use VERY LITTLE voltage and speed when idling, ANYTIME you idle. (Even browsing can be considered idling.)
Enhanced Halt State (C1E): Enabled
CPU C3 State Support: Disabled
CPU C6 State Support: Disabled
Package C State Support: Disabled
Fixed Mode: Your CPU will run full voltage and speed all the time, even when idling.
Enhanced Halt State (C1E): Enabled
CPU C3 State Support: Enabled
CPU C6 State Support: Enabled
Package C State Support: Auto


Which one is better?
Neither is "better". The first one will save you power and money, the second one will ensure you have 100% CPU power all the time. Some choose the 2nd option because they don't care about the electric bill and they like to have the best stability and power they can have. If, like me, you choose the 1st option, you will not be penalized.

Don't forget that each one can still use Sleep / Hibernate both of which will reduce the PC power usage to almost zero.

hey guys new to the forums here, and after purchasing my h100i i thought id give overclocking a shot. Because i have an asrock z77 extreme 4 i figured id follow this guide for my i5 3570k. After going in and out of the bios and testing a couple times i was able to overclock at 4.4ghz with my core voltage at about 1.296 with max temps reaching 70. Because I dont have much experience what do you guys think?

Check your C-states against the guide. You should be idling at 16, when that happened to me it was my C-states, they are responsible for downclocking. Use cpu-z as your numbers, as was hinted to by adrian154 a few posts ago, VID does not equal VCore. I like "Open Hardware Monitor" because I can see my WHOLE system...literally every sensor gets read and reported, and can be logged and graphed.

if you don't find any inconsistencies in the bios settings, format a thumb drive in fat32 and hit F12(I think) to take a screenshot and post them up here. Sometimes having a second set of eyes on the settings helps.

Not bad, what LLC? you probably have some head room if you want to push it.

Atm its at level 3

I've managed to get my 2500k to run stable at 4.6GHz @ 1.392v (is that a bit much?). Anyway, if I'm not mistaken, I could go higher however for some reason I've noticed that the CPU spikes in speed during boot. I don't know how accurate it is, but I'm watching the Intel turbo boost monitor at boot and sometimes it will show it go up to 5.1GHz, at which point the computer freezes and I have to hard reboot it. Is this normal?

I went into the C State section and disabled C3, C6 and that third one that needs to be disabled (c state support or something). I logged back onto my PC and the multiplier is still at 41 idling. I'm going to try to get the screen shots up here.

EDIT: I plugged my flash drive in while the bios was up and the bios froze. I had to hard reboot the pc. This flash drive has two parts. One part is a fat32 formatted removable drive. The other is a software that provides password protection and some other software features. This 2nd part shows up under my computer as a separate drive. So I am guessing this other drive (which is considered primary by my computer when the drive loads up... I just usually ignore it and only use the removable drive) is maybe not allowing me to get the screen shot.

Nevertheless when I went into the Advanced cpu configuration, my settings matched the ones from the guide for the offset method. and everything that was supposed to be enabled on that page looked to be enabled.

Edit: is the screen supposed to freeze in bios when you plug in your drive and then unfreeze after you take the pic? I just realized I didn't hit F12 on the right keyboard when I plugged the drive in.

Edit: I went back into bios and checked everything and it looks like all of the selections match up with the guide. But still the idling multiplier is 41. frown.gif.... do you think I should try the fixed mode configuration? If I were to do that would the only changes be to the c states?

So I tested some more and here are my two options:

4.6ghz @ 1.360v vcore

vs

4.8ghz @ 1.464v vcore

Now I know its just 200 mhz for over 0.1v but what do you guys think? Is it worth it? Probably not. Is it freaking fast? Hell yeah biggrin.gif It's my first overclock so I want to do it as best as I can. The 1.46V on vcore will surely shorten my CPU lifespan but just for how much? Please let me know some opinions.
