(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.

No those are two different settings.

Disable PLL overvoltage

and change CPU PLL to 1.72V

I've done everything you said, but.

CPU Current Capability can't go higher than 120%.

CPU Fixed Frequenzy can't go higher than 350.

And for PLL Voltage, all I can do is go from Auto to + 10.0v.

Now, lets see how stable it is. BSDO almost right away.. :/

It's very possible that your chip is one of those chips that cannot achieve such high clock speeds. What voltage were you getting when you were running manual 1.35V with Prime 95?

It just BSODS on me, but Id say 1.392-1.400

If this is such a chip, will say like an 4.4 or 4.3 OC serve close to what a 4.5 would?

Even if you run the chip at stock settings you will hardly notice any performance impact. You should be able to hit 4.3GHz on this chip though.

You think it's just that I have one of those chips who need a little more voltage? What would you consider safe before I stop adding more voltage to see if it helps. Also, when experimenting with voltage, should I have LLC on Extreme or Ultra high?

Load Line Calibration should be on High for the most part if you are shooting for 4.5Ghz. You can try with Ultra High though and see how that works.

Like I said before, 1.45V is the absolute max temps permissable. If you are hitting 80's with those voltages you will hurt your chip over time. Try keeping it around 1.4 for the best results.

It's also worth noting that your motherboard's power design is not the greatest in terms of overclocking, however I have seen large amounts of people being able to overclock on it to 4.5Ghz.

With, LLC @ Ultra high and Manual voltage @ 1.39v in BIOS , resulted in passing Intel BT at maxmium while CPUz showed a voltage of 1.400 peeking at 1.408. Temps recorded was, 63 Core1, 70 Core2/4 and 71 in core 3. Any inputs?

Good, try lowering the voltage inch by inch until it's unstable now. 1.4V is okay for that chip, but you should be able to use much less voltage for it. Try 1.38V then go down by 0.005V each time until you get a BSOD then you know that's when it's unstable.
