Thefollowing appear to be very similar to the T4200 but run at a higher spec clock speed. Would any of these be viable and of course would it even be worth doing on such an older machine now? Would the BIOS support a higher clocked speed CPU?

Yes there is a point in going slower as long as your pc supports dual channel.

You currently have 800MHz if you hace dual channel the memory will clock down to 533Mhz and then multiplied twice which is 1066Mhz

It is a setting which allocates memory to your cpu (Long story)

and as I can see, your PCH supports 1066Mhz which will make it intresting.

If my above options are right you should have the NVIDIA GeForce 9200M GE with

256 MB of dedicated video memory since that is the only one with nvidia in this document with an intel CPU marked with an X.

It has become a main use all rounder (replaced the desktop) take everywhere pc and a do everything from web use with multiple pages open, (and background programs paused or stopped due to its imitation), to often running Microsoft Flight Sim which likes a higher clock speed CPU and is struggling at times to run at decent frame rates. Loading programs and files faster would also help. Havent really tried other CPU and graphics intensive gaming on it. Cooling pad is used to stop it frying.

if it will support the T5900 2.2Ghz at 800Mhz FSB with 2mb L2 cache, Im thinking it will prob support the highest spec up (which was probably not available at the time the manual was written - same as there is no mention of the T4200)...

The thing of concern is whether the bios needs updating as it is currently set to run the Dual core T4200 and these others we're talking about T5900 / T9500 are a slighty different class of cpu (core 2 duo).

Lastly of course if a cpu replacement like this to suit is going to cost more than the thing is worth - then it may just be a case of putting up with its limitations and eventually replacing it with a new machine.

If that chipset supports a T9600 at 2.8Ghz with 1066fsb and 6mb L2 cache (or a T9550 at 2.66Ghz) there's prob no reason not to use that one. It just means (if it works) it should only run at the 800Mhz fsb of the DDR2 since the mobo cannot accept DDR3 ram.

Yes I saw the comparison link to the i5 yesterday.. if this works it should become a more useful laptop - as for heat - it is still a 35W cpu with a 45nm Lithography so unless it's clocking at max speed continuously, heat should not become a major issue esp with a fan cooling pad on heavy processing use.

Interesting. So youre saying that even if the board only physically accepts up to 2x2Gb 800Mhz DDR2 RAM, if a CPU (like the T9900) is rated at 3.06Ghz but dependent on a 1066Mhz FSB to achieve this, there may be a possiblity that the system may clock down to dual chan 533MHz and actually run that processor at its rated FSB and therefore internal 3.06Ghz clock speed...?

So if the T9900 will run at its rated 1066 mhz FSB on this mobo it should achieve its rated internal clock speed. If however it is limited to only run at 800Mhz FSB it will only be able to achieve an internal clock speed as follows:

Therefore if the board cannot physically run 1066 Mhz (dual chan x 533Mhz) on the DDR2 RAM, then we are limited to using the T9500 which with its higher mulitplier should perform faster than the T9900 (at 800Mhz FSB).

I noted also in some of my reading somewhere that the Processors named "Dual Core and the Celeron variants" are in fact the same as underperforming "Core 2 Duo" and multiplier factory locked and branded as such.

You are actually asking it to run faster.... 533 x 2 (1066Mhz) which it may or may not do?? Most likely from a mobo physical issue trying to get DDR2 Ram to do it or not wired up to support that or the DDR2 RAM itself may not clock up. I dont have any experience with this to know if it would work.

As an exercise I used SETFSB to see if I can clock up the FSB on the current T4200 at all and it seems to fail everytime even on a small increase. I used the closest clock gen option I could find (ICS 9LPRS355BGLF) to mine which is ICS 9LPRS355BKL.
