Intel Centrino Overclocking Guide Posted!

So far I ramped it up from 1.3 GHz to 1.45 GHz without any adverse effects. I'm going to Ghost my system tonight and then try pushing it further.

Even just the extra 150 MHz had a noticeable improvement in Doom 3. Likely because of the oc'd memory and AGP clocks on top of the CPU.

I also got a Dell Latitude D800 and I also want to overclock my System.
I used Clockgen CG-CY28346 and first it seems to work well, it shows me the right values (get values is working) but there is a big Problem:

As soon as I klick on "set values" (no difference if i overclock or if i don't overclock) my system freezes.

Which components do you have (maybe a bit different from mine, i have the Ti4200 Go and the Centrino/Pentium M 1,3Ghz with 512MB RAM)?
Do you have any idea why Clockgen causes a system-freeze on my sys?

i have dell 8600 dothan 2.0 pro turbo 9600 and a gig of pc2700 and mine freezes also when i hit set value, i would love to be able to overclock a little. i did the heat mod on the graphics card and can overclock the snot out of it. i wish someone can figure out how to overclock this beast

Hello Pug,

Just an update. I checked my brother's M30 and true enough, it was running the memory at 133MHz, instead of 166MHz.

Have you guys tried the other ClockGen?

The thing is your Dell notebooks may each be using a different motherboard with a different clock generator.

got it to work on my 8600 with the dfi 855 clockgen
thanks everyone, it doesnt show increase in cpuz but benchmarks are better

That's great, rangerone!

[rangerone]

i am not sure if it works or not. sis sandra lite shows no real improvement, cpu-z shows old speed. but my laptop doesnt lock up when i hit set value. not gonna use it, if it doesent work. i had overclocked the fsb up to where the cpu was 2.6, i should have seen a drastic speed up with that high, so for me it wont work, sorry

anyone who can help with this please let us dell users know.

dell 8600 2.0 dothan
128 ati 9600 pro turbo heat modded with copper shim
2x512 kingmax memory
60 gig 5400 rpm 16mb buffer toshiba hard drive
usb soundblaster audio

someone please find a way to overclock these

Oooh.. That isn't good news at all.

There is no performance improvement even after you set it? ClockGen showed the proper values after you set it?

If you do not record any performance improvement after using ClockGen to set the clock speed, then it's very likely that ClockGen is not able to actually control the clock generator used in your notebook's motherboard.

its got 855pm chipset. no go on the overclock so far.

No-no.. Please don't misunderstand.

The chances of overclocking has nothing to do with the processor or the chipset. It's all down to the clock generator.

You may have a i855PM motherboard just like the M30 used in the guide but your motherboard may come with a different clock generator. If so, then the ClockGen utility used for the M30 will not work for your notebook.
