A problem with OC

[Etus]

I want to OC my CPU.
I have Matsonic MS7117C(with VIA Apollo Pro) 133MHz MoBo and a Intel 800EBMHz CPU. In the BIOS, there's an option to change the CPU speed, or, just the FSBxCore Speed.

Even if I change it, the computer still detects my CPU as 800MHz(the CPU reg. speed).
Why?

I don't have a mobo like yours, but,--in bios
Do you have a "speed error" option? If so, disable it.

[Etus]

Nope, I don't have that option in my BIOS.

Etus---As i stated, i don't know your mobo.
It may not be o/c friendly. Try cpu database,
look for your cpu. You may also find a mobo
like yours to compare. (link on main page)

Sorry, i can't be more help.

Are you changing the FSB only? That's the only way you can overclock your CPU. If so, have you used anything like WCPUID or Sandra to check the actual speed in Windows?

The only way you can change the speed is through FSB as Intel has started locking the multiplier settings since a while back. What your bios is doing (just like mine) is trying to change the multiplier. If your mobo is using an 133 FSB, I think it's the max that it will go. However, if your mobo supports it, and you feel adventerous, you can try to change the bus speed to a higher frequency using CPUCool (13 day trial). What it does is change your PLL so that the FSB is higher (resets on power down). You have to know your exact mobo version, the PLL info will set automatically (if your mobo is supported). If it isn't but you know the PLL then you can set it manually. If your comp freezes (doesn't always happen) when you OC, just push the reset button. When it starts up again, the bios should say the OCed speed. However, if it doesn't start up, then you have to turn power off, then back on and it will reset. Another note: the PLL info for some mobo's is inccorect. It usually sets the right manufacturer, but the PLL type is wrong. You just have to play around with it to find out the right type, but you should really try and let the prog use the defaults.

PS: Do small increments at a time. Try going one option up from 133 (to set the FSB press on the Set Frequency option (ignore everything to the right of that button (just junk options). You should also make sure that you don't OC your PCI too much (33 is defualt). Hopw this helps (did for me; running Celly 633 @ 1Ghz)

I downloaded CPUCool, and the program's looking great - but I have one problem - it doesn't detects my MoBo.

I want to set it manually. What's the PLL and where can I check my MoBo's PLL?

I believe ther eare instructions on the website where you got the software, or in the software documentation itself. I'll have to double check to be sure.

EDIT: Yep. Check the website again (if you got it at podien.de (http://www.podien.de), anyway). Front page there, "Here are some tips for finding the PLL". Linked on the site.

Don't bother cooling while its idle since it cools down by itself while idle and you don't use it during idling so it doesn't matter just a good ram killer :)

And if you have NT Kernal it has a built-in cooler.

Finding out your PLL by looking on your mobo is a hassle (if you can find it). CPUCool won't autodetect your PLL info for you. You have to select your exact mobo manufacturer and type and then just click yes when it asks you about the PLL info (you have to hope it's the right info). Then OC and c how it works. If it gets frozen, you have to reset (not shutdown) and see if your comp loads up. If it does and everything is fine, then you've OCed succesefully. Some probs are:

Prob: CPUCool detected the wrong PLL type but right PLL manufacturer
Solution: Change the PLL type to one higher or lower, if that doesn't work, go through all of them. Don't worry, if it's the wrong type it will either tell you or freeze (just reset in this case) or

Prob: System resets to orginal clock speed after power down
Solution: None (good and bad; keeps you from putting a frequency to high and not being able to change it back)

Prob: System crashes
Solution: Set FSB lower

Hope this helps
