Confusing inconsistency.

addle_brains · 08-17-2007, 03:34 PM

Okay, I overclocked my E6750 using the AI tool that came with the MB. It then reboots and POST shows the correct clock speed, windows "my computer" properties shows the correct clock speed but CPU-z shows the same Bus speed but with a 6x multiplier instead of the proper 8x. Which one do I believe?

Well "windows my computer properties" says aload of shizzle because it says my cpu is 1.75ghz which aload of plop because my BIOS says i have 2.2ghz and so does my dxdiag command. so obviously you wouldn't beileve the computer properties.

addle_brains · 08-17-2007, 03:52 PM

Yeah, but it reflects what POST says. CPU-z doesn't.

I would recommend OCing in BIOS only.

I think if you overclock in bios, you shouldn't have problem.

Okay, I unistalled the ASUS AI tools. Rebooted and checked the bios. I couldn't actually find anywhere to manually change the any clock setting except for the multiplier (which I manually set from Auto to 8). The BIOS does, however, display the CPU setting (i just can't change them) and it is successfully overclocked to 3367MHz.

OK, back in Windows. Open CPU-z. Its back down to a 6x multiplier. Then I open Firefox and it jumps back up to 8x. I think I have to blame my board. It will automatically overclock itself when it needs to, and as far as I can tell I can only tell it what clock speed to go to in the AI tools.

Any thoughts?

Most, if not all chips do this. Speedstep, cool and quiet, etc. It's mainly there to save power and stay cool when the chip is idle. You've noticed that it will jump back up to the right mult. when it is being used, that will always happen, and as such It's nothing to worry about.

addle_brains · 08-18-2007, 09:45 AM

I'm not too worried, no. Is it common for it to only need this higher clock speed when opening a program? Because once the program is open it clocks back down straight away, which I suppose is ok, because that's how these programs work. Is there a program that will log my CPU clock speeds for me so I can test it out during gaming or something?

As long as it's under load, the chip will stay at it's specified setting. But to answer your question, I don't know of any apps that will LOG the speeds and such while you're gaming. I'd just keep CPUz open and alt tab out to check.

Well, it seems that when I alt-tab out of it, it's back down to the lower clock speed (which, fyi is under the rated 6.67GHz)
