How do I find my pll?

pll? What is that?

Pll stands for "phased-locked loop" which is what controls the clock generator (speed) of the cpu (the pll is part of the motherboard, and i).

Wikipedia has taken a very technical approach at pll's....

anybody have any luck with this chipset??

multiplier?

I might also add that in order to overclock, using software based utiliities, you should know your pll. (either by stripping apart your board, or hoping someone can tell you what it is via your chipset.

yes

Your multi is in the cpu... not mobo. CPU-Z has it under the heading of multiplier on the defualt tab... cpu

One other thing... you mentioned that you didn't want to tear your laptop apart looking for this... That means two things: that you expect to find a discrete pll part and that you are hoping to OC your laptop.

Thank you. You put a smile on my face.

lol hairy that was unnecessary

yes, I understand the multiplier, but what I am looking for is my pll, which is a series of letters and numbers, cpuz does not seem to read that.......and there was no need for what you said before, I've seen people OC centrinos, so why not a p4?.....

It doesn’t make any since to OC a laptop. Laptops aren’t really built to handle the additional cooling requirements and it will kill you battery life. As for the pll... what determins your cpu speed is the system bus multiplied by... um.. the multiplier. If you take a cpu... like the Q6600 you have the system bus of 266 (FSB/4) mulitplied by 9 (cpu multiplier) you get ~ 2400 (cpu speed). Are you looking for a way to increase the system bus?

I'm looking for a way to raise my front side bus....

Ah... that is a bios option. There used to be small switches or a series of jumpers that were used to do this very thing. On any modern board, this is done with BIOS settings. I really doubt there is that option on a laptop; with the increased heat that over clocking would cause, it doesn't serve a manufactures interest to allow for that in the bios. There may be software that allows this... I really wouldn't recomend OC'ing a laptop, though.

Check out ClockGen. I of course don't recommend OCing a laptop much less through Windows.

Which is exactly why I'm trying to find my pll without tearing it apart....I decided to just have this as an extra computer.

^Try ClockGen. Again reason for not OCing a laptop is higher heat output which the heatsink may or may not be able to handle.

Again I mention: I must find my pll in order to use clockgen!

Ahh.... I see. Have you tried the "Read Clocks" under "PLL Setup" in ClockGen?

No, I've always oc'd via Bios. I've never used Clockgen so I would have to google up a good guide on it, or you can give me a quick rundown on it.....

Thanks

I had the same problem. I wanted to find the PLL in my laptop as well. I have an eMachines E620-5885, a.k.a. the Acer Aspire 5515 and the PLL # is ICS951462. For anyone who wants to know. I used clockgen to UNDERCLOCK my laptop because I run XP on it so there's room to reduce performance and I wanted to cut down the heat and increase battery life so I reduced it to 1.4GHz. Not much of a noticeable performance difference but it is noticeably cooler.
