2500k not showing full OC in CPU-Z?

post #1 of 4
Thread Starter 
I'm new to the board so any help you can provide is appreciated. I'm not sure If I reached the limit of the CPU or if I need to do something else. Basically I can only OC the CPU to 4.4 and no further. My CPU boots no problem at 4.5 - 4.7 ghz with increased voltages but when I run Prime95 and look at the speed in CPU-Z it's never at full speed. It only shows a constant full speed when I have set it to 4.4 ghz. Aida64 will also show that my CPU is at 4.5 , 4.6 etc but CPU-Z never reaches that speed when running Prime95. Is it a voltage thing or something causing it to not reach it's full speed?

First fill out your complete system specs here.

What I think the problem is: many boards have a power draw limit. My board calls it "CPU Current Capability" and is set to 100% at default. What you should do is increase this number very high, because if you don't what you're experiencing could very well happen. Different boards call it different things, but basically you're looking for a number either in amps or % that limits the power draw or current of the CPU. If left at default, it could cut you off for example at 4.4ghz no matter how high you set the CPU itself.

The 2500k will idle at a low ghz and if you use a program like super pi it will show it working at the oc temp and then idle when finished. Sandy bridge is so efficient

It appears you were correct. I increases the wattage from the preset 95 and it seemed to work. Thanks stay at the constant speed I set. Thanks !!!
