Problem overclockng my i5 2500k on an MSI P67A G43

post #1 of 27
Thread Starter 
Hello guys, new to the forum. I'm having problems overclocking my 2500k on my MSI board.

I followed this guide to the T... http://www.overclock.net/t/963798/ms...w-and-oc-guide

Just received my Hyper n520 and installed. I changed my frequency to 4.0ghz and did everything in that OC guide and when I boot into windows, I turn on PC Wizard and the Frequency dropped from 3.30 to 3.29. Even in Windows basic information, it dropped from 3.30ghz to 3.29ghz. What did I do wrong? I remember overclocking my e8400 no problem. Could my bio's be wacky? Should I try using an overclocking software or is that messing with trouble? I only want to get my CPU to 4.2ghz, so I'm not looking to push the crap out of this thing. Oh and my temps are idling around 29-31, which is good I'm assuming! Just my frequency won't change! Any help would be awesome, thanks!!

First, welcome to OCN. If you havent already geadover and introduce yourself in the new members area.

Ok so 4.2 is a pretty basic OC for that chip.
First go into bios and load the optimal settings.

Then in the main OC page. Set your multi to x42
Whth that you SHOULD be able to leave all your voltage settings on auto.

Then disable the following settings on the Overclocking main page...
-Adjust CPU ration in OS
-Intel turbo boost
-OC Genie button

In the Cpu config page...
Disable Limit CPUID Max
Disable C1E
Disable Overspeed
Set C State to 'no limit'

If you boot up just fine start running Prime95 and see if you BSOD. If you do it will probably be a 0x101
Go back in and start manually setting your vcore adding .005-.010v and test on Prime 95 again.

I think I did most of those settings based off that guide. I will try again and post what my results are. Thanks for responding!!

Still didn't work, what the hell is going on?!

CPU-Z readings

And now I'm getting this very small noise which sounds like it's either coming from the CPU or the fan..

Anything in those CPU-Z readings look wrong?

Awesome, just read the CPU whistling sound is due to high temps. This keeps getting better and better. Going to restore everything back to default now.

Temps are reading as followed...

So how am I having temp problems?!

No your temps look fine. And the screen shots of CPUZ look normal to me. Its down clocking at idle to 1.6GHz as speed step is designed to do. Give me a SS of CPUZ and realtamp while you are running Prime95.

EDIT. Just noticed you are showing 99.8 buss. I had the same thing on my GD65. Im not sure what causes it but im pretty sure its a bios bug on MSIs part. Try disabling Speed step and see what it does.

I'll do it a little later. I alt tabbed out of a game really quick with everything set back to default and noticed in CPUZ that my core speed was up to 3.6 something, so I know the turbo is working. Maybe the tools don't read my frequency but they're still up? I'll change my multiplier to 40 and run a game again and see if it jumps past 3.7.

What was that small whistling sound coming from my cpu, though? It was only when I had the multiplier set to 42. At stock, there is no sound...

as far as i know the 99.8 bus is a symptom of spread spectrum's modulation.

WEll I guess it did work after all. After i alt tabbed out of the game

99.8 is bad? I'll disable speed step and see what it reads at after that.

Also after reading, that sound I'm getting could be capacitors?

I didn't see no speed set option, but I did see spread spectrum. Should I try disabling that?
