(adsbygoogle = window.adsbygoogle || []).push({}); I'm really tired of this shit now. Thinking my OC is stable and running smooth when.. BOOM! BSOD or other errors. :impatient: I really need help here as I can't seem to find stable settings for this fucking chip.

- High voltages. (1.4 - 1.5v on a 4.5Ghz OC!)
- Unstable. (Bsod, resets and stopping workers.)
- Inconsistent. (Voltages and frequency often dosen't match at all. 1.370v idle(1600Mhz).)

Specs.

Cpu: i5 2500k.
Cooler: H80
Mobo: Asus z77-v lx
Ram: Corsair Vengeance 8GB
Psu: Corsair 750W

I need someone with experience to walk me through the process of OC'ing this shit! I really woould like to hit 4.5Ghz.

Okay, 1) It's important to note than not ALL 2500k's can hit 4.5Ghz. Although for the most part a very large majority should be able to hit it without any problems of this sorts.

In your case, I am thinking that this is simply an instability in something else that is causing your overclock to become unstable, you may be running enough voltage through the chip but all the voltage in the world won't prevent it if you have something like CPU Spread Spectrum (ON) which can causes overclocking instabilities.

2) I am going to need to see your current overclock settings and work from there. Traditionally you should probably start 1.35V with LLC set to Medium or High and setting VRM Frequency to 390 or so. That's where I am at right now with my 2600k. You may also need to make some adjustments, for one you must make sure to set CPU current capability to 120/130%.

I would be more than happy to help you, just post your settings that you have so far and we can go from there.

I'll get too it, but is there a way to screen the bios? Instead of manually type all the settings down?

I believe there may be a feature on ASUS boards that allow you to take screenshots and save them to a USB.

Sorry the wait, got caught up! :worried:
Anyway, here's my settings(Images in spoiler on the bottom).

That's what I've tried as of now. What seems to be my problem, and if you need more info just shoot!

i tought there where features of asus boards where you can get stable OC's and run them also what about the OC genie of you have one

Hey sorry for leaving you hanging for a bit. Okay, so here is what I would start with to try to get your overclock stable.

PLL Overvoltage = Disabled

Load Line Calibration = Medium

CPU Current Capability = 130%

C1E = Enabled

Packaged C State Support = Disabled

Turbo Mode = Enabled

Speedstep = Enabled

CPU Fixed Frequency = 380

Finally, try this instead of Manual Voltage:

Change Voltage to Offset Mode

Change Offset to +0.015

Also try lowering your CPU PLL Voltage to 1.72-1.75V and see if that helps a bit with temperatures.

I'll try it out! I'm just playing BF3 atm, so I'll look in to check if you have come up with anything else in about an hour. Then I'll start trying the settings out.

Just remember anything over 1.45V is not recommended on these chips. :p

I would assume that 1.35v should be enough tho. I'm done gaming, so I'll star off now! =]

What should I use as a stress test? I mean not a stress test like prime for 24 hours but a stress that would see if the OC is worth stressing for a longer time.

Btw, disabeling PLL or lowering it's voltage?
