That is simply not the case. If your chip is reaching past the thermal comfort zone before it is crossing the voltage comfort threshold, you are a candidate. But, it is risky, and not everyone is willing to risk killing a chip for 15C or 200mhz.

Hello guys and girls,

i am new to the overclocking world and tried my hand on overclocking my 2500k that i bought used recently.
I was going for a 4.5 GHz overclock. I think i managed to get it stable and cool as i completed a 1.5 hour blend test.

My setting are.

Offset Voltage: -0.025
Turbo Offset: +0.004
LLC Level: 5

VCore Idle = 0.96
VCore Load = 1.272 - 1.288

EDIT: Idle temps are 29-30 C

Do these setting seam fine to you? I had to uselow LLC to get lower voltage for my motherboard in addition to negative offset.
Shoud i try lower Vcore even more? i haven't found the limit for this multiplier(x45).

Finally, in CPU-Z my BCLK fluctuates from 99.98 to 100.01 is this something to worry about? I seems that higher LLC Levels fix this issue.

I would let Prime 95 run longer then 1.5 hours to determine if its stable or not.

Regarding your BCLK, do you have spread spectrum disabled?

Yes, i have it disabled like the guide said.

How long is enough then? The 12 hours people say seems excessive.

Finally figure out why I've been getting those high temp it was my hyper 212. I took off the fan yesterday and found out there was a thick blanket of dust like the size two envelopes thick. after cleaning off the hs I was able to overclock it to 44x turbo 0.02+ offset -0.100 idle=1.080 load=1.24-1.256 going to do P95 for 3hrs, so far high temp is only at 84c on core#1&2. BTW i found out this after I already started the RMA process lol.

Depends on what you plan on doing with the machine. If you will loose time/money because of a crash, or an essential term paper, or really anything much more than gaming or web surfing...32 hours get you through the whole stress test, after then it starts to repeat FFTs that have already been tested (assuming you use the default 15 minute per test). If you just want to watch porn and play BF4...then a couple hours is fine...it may crash sometime, and you can just bump the VCore then. I only run an hour or two anymore...but this is just a gaming machine, not a render farm, workhorse, or school machine, but I have not had a BSOD related to VCore in the last 9 months, after only like an hour test with 5 minute intervals.

Turn your llc down to like 2. I have mine at 2 and it keeps my voltage pretty stable. The issue with it being at 5 is the fact that when your not 100% usage it'll up voltage of the core higher.

Try that

Try that

In offset mode when you are not 100% the voltage drops to 1V. Like i wrote before, my idle VCore is 0.96 not problem there.

Using LLC 2 gives me a really high VCore for this overclock and i have to use a more negative offset risking idle instability.

Thank you both for the info. I will report back if i try another longer run.

Hello,

 

Would this awesome guide work for Haswell?  I am using a 4670k on a Asrock z87 Extreme4 and having Hell of a hard time finding guides for this combination.
