First C3/C6 enabled overclock

 

4.3ghz - 4 cores

4.4 - 3

4.5 - 2

4.6 - 1 core

 

1.32-1.35v

 

I call it perfect ;) It's probably not the best overclock but I am happy with it.

 

C3/C6 enabled OCs are easy. But you need to do core per core. If you want all 4 cores at the same frequency at 4.6 ghz for example you need to add a big amount of safety zone for the vcore.

 

4.6 GHz - 1.32v - 1C

but requires

1.375v-1.4v for 4 cores. I thought it was just too much.

 

I suggest you stay between 1.425v-1.575v for DRAM voltage. I don't like going higher. The IMC is already so fragile. And by increasing DRAM voltage you put extra stress on the IMC. I read it somewhere. But I can imagine it's true.

It is the easiest and just as safe as a USB drive.

In both cases, if you cut the power during the flash you will probably get a bricked motherboard. All though I think these new motherboards for Sandybridge and up have a backup BIOS to go to when the 1st one is corrupted from a bad flash.

Just make sure you won't have random power cuts during the flashing process. I think the latest BIOS even disables your mouse during the flash, so you can't screw it up yourself by pressing the shutdown button.

1. Pump GHz using cpu multiplier
2. Leave ram settings at stock since it doesn't matter anymore.
3. Adjust voltage as necessary for stable overclock.

Obviously there's I'm important details I'm leaving out (like the max voltage for Ivy/Sandy Bridge) but let me know if this is generally correct.

Yep. If using offset, leave offset at +0.005v and use Turbo like you would offset. This will keep your idle at around 1v instead of it being higher.

my question: the cpu pll maximum can be lowered to 1.709v? can happen if low to 1.600v or 1.500v?

I would stay in the recommended voltage zone by Intel. The CPU is not guaranteed to properly work past the zone of 1.7v to 1.9v.

Should I pay attention to WHEA errors?

I have seen people saying they are important and should be considered unstable, but others say they are fine.

Thoughts?

Also, if it is important, is there anything except the offset that I can use to remedy a WHEA error?

Hey!

I was just clearing my cmos and cpu-z displays the wrong bus speed shouldn't it be at 100mhz?

I never used to look at cpu-z when i wasn't overclocking or anything. When i load my 4.5k oc profile cpu-z show the correct bus speed (100mhz.)

Is this normal i have a lower bus speed with the default bios settings? And a lower idle clock? 1596.66mhz instead of 1600.

404

I know im using a older version of cpu-z just trying out if this version displays it correct. guess not.

its prolly nothing to worry about but im just wondering smile.gif

Thanks a ton I'm new to overclocking and found this guide and will be using it for my new build.
Not sure if Rep does any good but you got one from me.

All the other guide I found confused the hell out of me after a bit and ended up with a head ache, why I never bothered overclocking this PC.
Kind of a waste of this core since it's unlocked.

For a brain dead overclock (non extreme) set your multiplier to

43

everything to auto

xmp profile (yes)

Anything past that will require effort. 4.3ghz can be done without any conscious thought needed besides entering "43"

yeah x43 and everything else on auto/default should work fine.

I can get x44 with changing LLC Load Line to level 4 and everything else on auto/default.

x45 gets tricky...

Make sure that you have Spread Spectrum disabled and use the latest CPU-Z. If the BLCK is set to 100.0, CPU-Z should report 100.0.

SS is set to on by default, so clearing the CMOS would set it on and report a different bus speed (look at my guide for more detailed info on SS).

The BIOS profiles hold ALL settings, so that profile probably has it disabled.

As far as Windows 7 (Vista too, if anyone still has that god awful thing known as an "OS") is concerned, the only thing to worry about is a BSOD (or freezing / random shutdown), errors in prime95, or temp limits (which would also cause a shutdown).

Any OS other than that, I cannot help you. I simply don't dabble in Mac, and Linux. Or old / unreleased OS's for that matter.

So you wouldn't worry about WHEA errors at all? I only ask because I am stable except for that fact frown.gif

Also, it seems that the voltage fluctuates a bunch at max, and that the WHEA errors correlate with the times where it drops. For example, here are my specs now:
Multi: 45
Offset: -10
LLC: 2
PLL 1.799
Turbo Volts: 0.004

I get an idle voltage of 0.98V and a load voltage that fluctuates between 1.224 and 1.248V. Is there any way to make it fluctuate less? I am getting WHEA errors at these settings.
