8.1 runs the same for me as 8, nothing should need to be changed at all for the overclock. There might be some snags with the "secure boot" crap, but cross that bridge if you get there.

Multiplier 33, Voltage Auto, Powersave settings disabled. --> Prime95 (small ffts).
Core Temp reports a VID of 1.2860V ... do I have the ****tiest i5-2500k for overclocking ever?

I have been trying llc extreme on the extreme 4 z77 mobo. With the same clock and basically same load vcore voltage I actually have around the same temps or maybe even lower. Could it be possible my board doesn't have the hidden overvolt?

4.7ghz with llc5 needs 1.304 max load. So I used extreme and my max vcore is 1.304 which is stable and the temps even seem lower.

you sound like you are mixing settings. when you say extreme, are you referring to LLC 1 ?

I was confused because the ext4 does not have the "extreme" language attached to LLC1, where there are some boards that actually call it "extreme". Something is wrong with the setup, LLC1 should without a doubt provide more voltage at load than LLC5, all boards should behave this way, as it is the way they are designed. Considerably more in fact. The only way to test if your board has the over voltage issue is grab a hold of a DMM and check the VCore from the pins on the back of the board and compare against software reported VCore. The two issues you mention are independent variables. LLC has been shown to affect the level error of over voltage, but there is no LLC setting that doesn't suffer from it on the EXT4.

Hello fellow overclockers.

So, I thought I'd give it a real try and actually do something besides leaving voltage on auto and going for a 42 multiplier on the CPU.
My first goal is to reach a stable 4.5GHz clock, and so far so good!
Followed all the steps and set everything in BIOS as the guide says.

I've had Prime95 running for about an hour with my CPU at 4.5GHz with a maximum Vcore of 1.200v, average value I see is 1.184v
(Goes up and down I'm eyeballing the hell out of HWMonitor/CPU-z) biggrin.gif

And if I follow the steps in the guide, I'm not entirely sure if this was way to easy or if I'm simply clueless when it comes to Overclocking:
- Started with offset: +0.005v and turbo + 0.004v, went from 50 multiplier and down to 46 then it booted up and ran Prime95 for about 15 minutes untill BSOD.
- Lowered to 4.5GHz, and it's been running just fine since then.

So my question is this:
Do I leave it as is for another 11 hours and call it done, or do I try to lower Vcore to get a more green overclock, according to the steps I'm supposed to go as low as possible but since I'm at the starting point here I'm not sure I should go any lower when it's just +0.005v since that would mean I go with a negative voltage, right?

I guess within 12 hours I should probably have another BSOD and then up the offset, right?
If it runs fine I guess I'll just leave it as it is unless you say otherwise.

Take a look at my numbers here and see if they are ok and recommend me what to do next, I shall be waiting for your guidance through this jungle of numbers. smile.gif

Whats you idle vcore in CPU-z?

If you receive another BSOD during prime 95 then you will need to increase Additional turbo voltage not offset.

I ran P95 for nearly 15 hours no problems so far.

It says 1.192v in CPU-z but I noticed that it says +1.008v in BIOS, is that normal?

Yes, that normal. Bios shows the vcore that is being use while in bios rather than a full load vcore.

Do you have your power settings in windows set to balanced? Your multiplier should drop to 16 and idle vcore to 1.00v or lower.
