Swapping Laptop CPUs

So here is a really basic question and I dont see any reason you couldnt do it right off hand.

If I purchase a laptop with a ML Turion processor, and get a MT seperately, any reason I couldnt swap them out to get the lower power chip in the notebook and hopefully help it run a bit cooler?

Looking at picking up an Acer(Since those are the most common Turion based I have found thus far) but all they seem to come with are the ML chips.

Actually, you should be able to just lower the voltage to 1.25V and have yourself an MT version for free. It is highly likely that pretty much all ML versions can operate at default speeds on 1.25V. Most can probably go even lower.

What you will need is an application that can change the voltage on Turion laptops. I'm not really sure if there are any such apps. I'm sure someone on these forums knows this, though.

I would guess that you can change the CPU to an MT version if you want to, but to be honest, it all comes down to what kind of CPU support that the BIOS implements. It is kind of likely that a Turion MT will be recognised as an ML version and thus be fed 1.45V, providing for zero gains in the power consumption department.

RMClock can do it, and it's fairly reasonable to expect that the MT would have even more undervolting potential (though it's possible that it wouldn't.)

Yeah it will depend on the BIOS. The Acer may or may not support the MT versions of the Turion.

As Mikael and YuriSEAL have said, the safest way to go about this is use a software utility lower the voltages. (may or may not work, you'd think if these things could run at lower voltages that they'd be selling more MTs instead of MLs; they're no more expensive)

They just aren't shipping very many MT processors, for whatever reason. Or, at the least, they aren't making their way into many notebooks.

The MT's top speed is 2.0ghz, and its lowest is 1.6, so it basically just took them in increments of 200mhz... its probably just good marketing, who knows?

So anyone know any good undervolting software for linux
