i5-2500k overclock (no PLL voltage control)

post #1 of 4
Thread Starter 
So I have no PLL voltage control. I can't figure out what the voltage is for the PLL and I can't control it in bios, even after updating my bios I still have no control over it. Sad day... I just need opinion on whether my overclocking then is safe or not. I'm stable at 4.4GHz, look at how low my temps are with the freezer 13...


Notice, im only running 1.248V @ 4.4GHz. With those temps too, if PLL voltage isn't a concern, I could probably bump that upto what? 4.5-4.7GHz?

Looks good,however you may want to think about running it a little longer just to be 100% sure. Temps look amazing, however I recommend using realtemp for sandybridge, you can grab it from here: http://gigaflopd.com/downloads/realtemp/

With different motherboard model's there are different BIOS's, usually the more expensive ones tend to have all the little voltage tweaking available, however there are times where some of the important ones like LLC controls and vtt/pll are not apparent with the lower end motherboards, that is why some go for the more mid range or expensive motherboards.

Hope that helps clear things up

I've gotten the 2500K all the way to 4.4 without a voltage bump. At 4.5 or higher you'll probably need PLL overvolt to get into Windows. So try it, but you may be disappointed.

I'll run a prime 95 test tonight. Like a 8-10hour test.

What is interesting is 1. I haven't had to bump up the voltage much at all, I don't even know how low I can go before I get an error or not. I'm just going up a multiplier, and with that upping the voltage 1 tick. Also, my temps haven't risen much at all. Maybe, maybe 5C tops, going from stock to this OC.

I've tested real temp and the difference between real temp and HWmonitor is about +2C in hwm. So real temp will max me out at about 54C and I'll get about 56-58C in hwm. Plus I like hwm because it shows me my motherboard temps, which right now I have no MOSFET cooling. As you see my MOSFETS on the board max at 59C, which is my other question, is that OK? I read somewhere that 70C is max temp for MOSFETS so maybe I need cooling now for them...
