Overclocking: Limited by BIOS or CPU itself?

I want to know if the option to overclock a processor is limited by the BIOS or the CPU itself?
For instance, if I purchase an HP DV6t with a C2D 2.9GHz processor, bring it home and strip out the processor and put it into the allpowerful M17x, Will I be able to overclock that processor or not? Will the pins even fit? lol.
Just a thought about stripping another laptops processor and putting it into the allpowerful M17x and see if it overclockable.

Thanks guys! =)


*sorry but this is not a thread about "how far I can clock..."

 

Which processor is it? If it's a Montevina based proc it will work.

 

If that CPU is a Montevina CPU then yes, as Mandrake said you will be able to plug it in your M17x and it should work.

As for CPU OC, it can be limited by both the BIOS and the CPU, which one will max out your OC first I don't know.

 

different computers provide different voltages

 

the option to overclock is limited by the owner of the notebook. jks

But to answer your question, Both the notebooks you mentioned are socket P (I think, I'm not sure about the M17x). So if a CPU works in the HP then it should also work in the M17x. They should be pin compatible.

 

more then likely the CPU would overclock better in the M17x due to the better chipset and better voltage.

 

These are the different processor on the DV6t:
Are they overclockable?

- T6600 (2.2GHz, 2MB L2 Cache, 800MHz FSB)

- P7450 (2.13GHz, 3 MB L2 Cache, 1066MHz FSB)

- P7550 (2.26GHz, 3 MB L2 Cache, 1066MHz FSB)

- P8700 (2.53 GHz, 3 MB L2 Cache, 1066MHz FSB)

- P8800 (2.66 GHz, 3 MB L2 Cache, 1066MHz FSB)

- T9900 (3.06 GHz, 6 MB L2 Cache, 1066MHz FSB)




HP doesn't have the option to overclock processor in their BIOS, so I don't really know if these are overclockable at all even if i swapped them out and into my M17x.

 

Yes, via front side bus over clocking, on the M17x.

 

what crylo said is correct

 

Now, I was trying to look up some comparison between the performance of the Extreme X9100 vs the T9900.

Are there any difference in terms of overclocking and stability?

They both have same specs except the X9100 give off more heat which I don't mind because the M17x can handle it.

 

T9900 is 35w, so it will give off less heat than the X9100, and probably over clock better.

 

but you could also overclock them while in the HP unit.

Either software (setfsb) or a hardware mod (PLL FSLC mod).
while these two methods should work, they are for power users.

 

only difference is the x9100 has unlocked multipliers which is kinda pointless with the M17x since a t9600 can hit 3,6 which is just as high as a x9100

 

You could if you could find the PLL, but then you would also be over clocking everything else in the laptop with the FSB, so he is better off transplanting the chip into his M17x, and unleashing it's true potential, while leaving everything else as is.

 

what do you mean by "everything else"?

I overclock my FSB and the only things that are overclocked are the CPU and the ram.

you can use SPDtool or thaiphoon burner to flash the ram to a lower frequency so that now the only thing overclocked is the CPU.

 

From my experience setFSB also over clocks your PCI and PCI-E busses, without the option to lock them to their normal clocks, has Audigy fixed that recently?

 

With my toshiba tecra a9 (and also a few other notebook I know of), the PCI and PCI-E busses are locked to their stock clocks.


Although you can use the bottom slider in setfsb to overclock the busses.

EDIT: who is Audigy?

 

Nice, I guess he has updated it then.

The guy who created setFSB.

 

the X9100 and t9900 are actually the EXACT same chip

same PCB and all just one has multi's locked

same with the t960 t9400 etc ...

 

Yes they are the exact same chip, T9900 is a bit more energy efficient model of the X9100 with the multipliers locked as you said.

With the lower wattage, I would love to see how well this chip clocks, I wouldn't rule out 4.0ghz.

 

Wow you guys are awesome!
Thanks guys!

So the T99 is recommended over the X9100 for the M17x- What I assume is the final word..

 

Yes I would recommend the T9900 for the M17x because of it's included FSB over clocking, and the T9900's lower 35w TDP.

 

i would say get it since its cheaper

 

I'd like to see a T9600 hit the benchmarks I got with the x9100.

 

I'v emailed him many times, but I always called him abo (or abo-san).

Anyway, he updates it frequently.
usually every couple of weeks or so.

In fact you can email him and tell him a few details of your system (including PLL) and he will update setfsb for you.

 

T9600 @3.3ghz:

T9900 @3.7ghz:

T9500 @3.9ghz (50%OC):
http://valid.canardpc.com/show_oc.php?id=647836

 

How about one for the P9700.

 

I don't use or have a need for setFSB, I have the M17x.

 

Sorry,can't find one
But it must obviously have simmilar potential.

I wish I were as lucky as you
setfsb isn't the best way to overclock.

and then again, a hardware mod to the PLL doesn't give you flexability.

So the best way is to have a notebook like yours.

 

that 9500 is in a m98nu ....

seems our chipset hates quads but loves duals
