Overclocked Intel I5

[LlamaWithARifle]

I have an Intel i5 2500k which I have overclocked to 4.5ghz just by changing the multiplier up to x45.

Everything seems fine but nothing seems to think it is 4.5ghz. Windows tells me it's still running at 3.3ghz, Orthos does the same thing as well with PC Wizard. However Cpu-z tells me it's running at 4.5ghz.

Should I just assume it is running correctly at 4.5ghz? Even then is there a reason everything is telling me it's still running at 3.3ghz and not 4.5?

Dunno about Orthos, but on my Athlon II X4 640 overclocked to 3.6GHz, Windows tells me its still 3GHz, but Coretemp and CPU-Z display the correct clock speed.

Load prime95 and CPU-Z to see if it rises under load.

Just changing the multi when overclocking is the worst possible way of doing it.

None of the figures seem to rise under load but I have disabled all the speedstep features since I don't really like them.

All the guides on the internet I've found about the i5 2500k all seem to say to change the multiplier rather than the bus speed so I've been going off them although I've always read about other cpus to change the bus instead of multiplier, not sure why they all say increase multiplier... is the i5 different or something?

Yes, it really is as simple as just changing the multiplier (so long as it's happy with the voltage). Mine's at 4.5 at the moment and while windows reports it as running at 3.3, CPU-Z shows it running at 4.5 (throttling down to 1.6 when speedstep kicks in).

Short version: It's fine.

I assumed that you left all voltages on auto, which would be bad in any case.

If you did not, that is fine.

Overclocking by upping the multi is the way to go but you need to have control over your voltages.
