multiplier at half speed

Specs: Microsoft Windows XP Professional (Corp. Ed.), 2.31 GHz / 1918 MB
I'm having a few problems with my CPU. I
originally had it running at 1.2 GHz when I put
the computer together and found out how to
disable the powersaving feature pretty quick.

Now I've started looking into OCing and i had
the processor up to 2.5GHz with 250 x10 and
the HT at 4x, but after trying to go faster than
that, the computer wouldn't even boot to the
Bios. I reset the CMOS headers on the Mobo
and set the Bios to what I had it at originally,
but now the multiplier in the bios is showing
11.5 and in CPU-z it's only 5.75

How do I get it back to normal, or even just get
the multiplier to be set properly? BTW, after
the reset I did have to disable the powersave
feature again, so that's not an issue.

Did you type that in another program & paste it here? Here's the corrected link:

Doesn't appear that you disabled Cool 'n' Quiet in the BIOS.

When you increased the CPU frequency & lowered the HT multi to 4x, what did you do with the memory frequency?

do you mean the memory clock frequency? I've got it set to DDR
800.
also, the quiet and cool feature was what i was referring to as
powersave, i was just lazy and didn't look up the name - yes, it's
turned off.

"do you mean the memory clock frequency? I've got it set to DDR 800"

Is that what you had it set at when you increased the CPU freq from 200MHz to 250MHz? If you did, that's your problem. You should have knocked it down to DDR 667.

"the quiet and cool feature was what i was referring to"

Double check...I don't think it's disabled.

Durrr...
It was disabled, but here's how i fixed it. I set it back to enable it,
let the system startup fully, then went back and turned it off
again.

It's fixed now, but should that have fixed it?

Also, any suggestions on boosting the CPU closer to 2.8 or
3GHz?

Increasing the CPU frequency by 250% is overzealous, especially with what I assume is stock cooling such as the fan and heatsink that came with your cpu. My question is why are you trying to OC this processor so much? Also, what processor is it exactly?

"any suggestions on boosting the CPU closer to 2.8 or
3GHz?"

When you overclocked to 2.5GHz, why did you lower the CPU multiplier from 11.5x to 10x?

I suggest you shoot for 2.875GHz (11.5 x 250MHz). To do that, start with the old overclock settings --- the CPU freq at 250MHz, CPU multi at 10x, HT multi at 4x. Lower the memory setting to DDR 667. Make sure CnQ is disabled (which you already have) & disable all Spread Spectrum options. Lock the PCIe at 100MHz.

According to CPUZ, you have the CPU voltage at 1.328v. AMD spec's the voltage range for your X4 at 1.0v-1.25v, so I assume you must have jacked it up? Did you experiment with other settings between 1.25v - 1.328v & find that 1.328v was necessary to stabilize the overclock? Or did you arbitrarily pick that amount?

Anyhow, once you've setup the BIOS using your old settings & confirm that they work, go back into the BIOS & raise the CPU multi from 10x to 10.5x (2.625GHz) & see what happens. If it's stable, go back again & raise it to 11x (2.75GHz). Try again at 11.5x (2.875GHz).

Below is a chart of Phenom memory dividers. You'll see that with the CPU freq at 250MHz & the memory set to 667MHz, the memory will actually run at 833MHz.

If you want to increase the CPU freq higher than 250MHz, you'll have to lower the memory setting to 533MHz.

"Increasing the CPU frequency by 250% is overzealous"

Huh? Where did you come up with 250%? The CPU frequency for ALL AMD CPUs since the dawn of the 1st Athlon 64 is 200MHz. Increasing by 250% would be 500MHz. I don't see any talk of raising the frequency that much. He's trying to overclock the overall CPU clock speed by 22-30%, which *should* be do-able.

"especially with what I assume is stock cooling such as the fan and heatsink"

You don't need an expensive HSF or watercooling to overclock.

"what processor is it exactly?"

If you had clicked on the link he supplied, you'd know it's an AMD Phenom X4 9650 Agena. Default clock speed is 2.3GHz -- 11.5 x 200MHz frequency.

I believe pcbiased thinks the cpu is a 1.2 ghz cpu to begin with. I dont think they know its 2300 and therefore should probably not be giving advice if they dont understand the post.
