Why is the rev. number come with MB or CPU is so important? What do they mean or represent exactly?

Does the cooling paste come with the CPU or do we have to buy it separate? What brand do u suggest? May you give me the link to that specifically in Newegg or anywhere you can fine since this would be my 1st time I change a mobile cpu Seriously dont want to mess things up

My BIOS' upgraded to 2.11.

Thanks!

it says my Package is Socket 479 mPGA
My CPU is T2700, I thought it's a socket M cpu, so is socket M is the same as socket 479?

Socket M is the upcoming Socket for the Santa Rosa platform (i.e. it doesn't exist yet).

Socket 479 is correct for Core Duo/2.

Look under the different tabs. Motherboard revision will be listed under one of those.

All but a VERY FEW early T60s are rev 3.

Where would be the best place for one to buy a T7600 at a fair price? Thx.

(if you swap back the chip, should it still already voided the warranty when we first opened the laptop?)

2. Do I need to switch/update my BIOS to the T60 Core 2 Duo version? (my current ver. is 2.12 Core Duo)

3. Do I need a 90W AC adapter for it, (mine right now is 65W)?

4. If there a full-instruction manual to do this on t60?

Thanks

Compared to the desktop Core 2 Duo (Conroe), the mobile version is architecturally no different. Obviously clock speeds (both CPU and FSB) are lower because these things will be going in notebooks where power consumption is more of a concern, but other than that the architectures are identical.

Compared to Yonah, Merom has some very clear advantages; on the surface the larger L2 cache is responsible for the 140M increase in transistor count, but architecturally the improvements extend far beyond that. You can get the details from the table above or from our previous articles on Intel's Core 2 processors, but simply put Merom is wider and slightly deeper than Yonah. The slightly deeper pipeline helps increase clock speeds on Merom (which will bump performance a bit), but the added decode and execution width will increase overall performance.

Not listed in the table above are the improvements to the cache subsystem and memory accesses on Core 2 Duo. Merom features more aggressive prefetchers than Yonah, as well as Intel's Memory Disambiguation technology that allows for out of order loads. In other words, not only is Merom able to operate on more data at once, at a faster speed, but it can also get access to that data quicker.
