Correct Overclock Results?

drunkenmunky · 23 Oct 2011 at 19:31

Just overclocked my i5-2500k using this guide but concerned about the results.

Everest shows a 27% overclock but CPU-Z keeps changing from 1600 to 2400Mhz.
Also CPU FSB is only 100Mhz but should be 133Mhz?

Your volts are a bit high for only 4.2ghz. I would try lowering them a bit (try between 1.3 and 1.35 for starters)

Your speed keeps going back to 1.6ghz due to intels speedstep technology (lowers speed till you need it and then puts it to full)

Thanks for the quick reply. I only went by the guide so I assumed that was ok. I'll try lowering them a bit. Am I able to push this further for a better overclock or should I leave it at 4.2Ghz?

No it shouldn't.

The Base Clock is 100MHz and you're not supposed to change it.

Ah ok, I just wondered why Everest shows it was originally 133Mhz.

That must be a bug in everest, SB base clocks are intended to stay at 100, all over the overclocking is done by the multiplier.

I would say the very least you should expect from your chip is about 4.6ghz, though most are over the moon with 4.5ghz.

How is the overclocking, did you manage to get a stable Overclock with lower volts?

Yes, thanks. It seems to be stable at 3.0 volts running at 4.2Ghz

Hopefully you mean 1.3 or something similar :eek:

Holy hell.. Gonna be your last post if you're right!

LOL Yes, 1.3...what was I thinking?? haha

What temps are you getting at that overclock? You should be able to push it to 4.5ghz with little or no volt increase.

drunkenmunky · 26 Oct 2011 at 17:29

These are my current temps on idle. Is this ok?

What about when you're stressing it? Try IBT or Lynx and run it through 15-20 loops with full RAM.

I had no idea what IBT or Lynx was so I googled them and installed Lynx and ran it without any errors.
I also ran HWMonitor alongside it and temps never went above 70C.

Here is a screen shot if it means anything to you..I have no idea what it did.

On the Memory option, set it to all or as much as you can. Those temps seem fine too. Congrats on getting it stable
