I have just got my i5 2500k, and I am running it in a GA-Z68XP-UD4 Mobo with a Cooler Master Hyper 212+ air cooler. I have set Vcore to 'Normal' and Offset (DVID in gigabytes case) of +0.000. I seem to be getting very low voltages at 100% load getting 4.5Ghz. I have attached screenshots - is this correct/normal or are the programs wrong?
Idle(but still overclocked just speed stepped)
Have only done around 15mins of Prime 95 will do more, but worried that the voltages reported are too low, and may have errors.
Thats good, I was worried that the voltage was too low and the programs were reporting it wrong. How do I know when it is stable? What programs?
The programs that are a must are...
CPU-Z - for in-depth observation of CPU/RAM activity
Prime 95 - the best stress tester out there. If your CPU can handle this, it can handle anything
Real Temp - for monitoring the temperature across all cores and the distance to t-junction max (the point where your CPU says, "to hell with you, I'm out of here")
There is also Intel Burn Test, which doesn't take quite as long as Prime95 to get a fairly accurate idea of how your CPU will hold up under stress. Still not quite as good as Prime95.
All above programs are free.
When you can run Prime95 for a solid 60 minutes without your CPU overheating and/or shutting down, you know you're good. There are people who do it longer (even keeping it running overnight), but they are idiots if they do it with gaming in mind, seeing as how gaming will never in a million years stress your CPU the way Prime95 will. All they are doing is putting unnecessary wear on their CPU for nothing. Run it for an hour and don't listen to anyone who tells you to run it longer.
