Yes it is, don't see an option to turn it off, however the above post seems to be right on it with the core current limit

yes that usually is an issue, but its per board, as manufacturers will set the limit at stock higher on certain boards than others.

i5-2500k CPU
G-skill ripjaws 8gb
gtx570 twin fozr 3
Gigabyte GA-z668x-ud4-b3 mobo

hmmm so, I just got my computer up and running and I'm having trouble OCing to 4.5ghz.

I followed the guide and disabled

C1E-DISABLE
EIST DISABLE
C3, C6 States-DISABLE
CPU Thermal Monitor-DISABLE

I think proceeded to set the multiplier to 45x. Then, I looked to see if my voltage automatically changed but it didn't so I manually set it to 1.350v. I ended up blue screening with the x124 code.

Should I try setting it at 40x or something?

So, I know overclocking capabilities changes from cpu to cpu. So far, I have tried overclocking the 2500k to 4.5ghz @ 1.360 voltage and it was a no go with constant BSOD's. So I dropped it to 4.4ghz @1.360 voltage and blue screened.

Now, I want to run intel burn test but I'm curious what settings to use and how long I should run it for.


I have 6465 available ram. Should I be setting it to Maximum so it uses all of the RAM or another option...


Also, what is the significane of voltage? Why do you want voltage to be as low as possible with you overclock? What is the significance?

yes you want the system to be stable, while using the least amount of voltage it can use.

So you want to find the lowest vcore were the system is stable.

What is your LLC settings at?

EIST should be in the same menu as C3/C6.

As long as your voltage are under 1.4v for 24/7 you should be fine, of course you can use higher, but not with 4.5ghz that is just a bad OC>

Ratio change in OC, can you enable that option too?

What bsod code you getting? 101, 124? increase vcore.

I don't particulraly have an LL option. The closest thing to it is "Multi-steps Load-line" and it has 10 levels "Level 1," "Level 2," ect...

I found EIST and disabled it as well.

I also didn't see anything having to do with "ratio change in OC" other than "real time ratio changes in OS"

change LLC to level 7.

and its called ratio change in OS, same menu as where EIST is, and its right before turbo, it will gray out turbo.

I followed what you said and changed those two settings. I am currently sitting at 45x multiplier at 1.355volts which I set in the bios. What i'm confused about is, looking at CPU-ID and CPU-ID hardware monitor it says that my CPU vcore is 1.38v and I have seen it go up to 1.412 currently with the intel burn test that i'm running.

Is that normal?

Stress level: MAXIMUM (6471mb) /// 800mb remaining
Times to run: 5


It also looks like I peaked at 79 degrees celcius.




My results, also notice it going up to 1.392volts on CPU-id? It has even peaked to 1.404... I set the vcore to 1.355 in the bios o_O
