Hi there,

I recently got a free laptop yes a free laptop...well the only catch was that the Graphics card had been cooked.

It was an Fujitsu Siemens Amilo M3438G which had a Geforce Go 6800M GPU in it. Fortunately that laptop had an MXM slot so I was able to upgrade the Graphics in it to a ATi X1800 GPU.

The mobo on the laptop is a Uniwill P71EN0 and the processor currently inside it is a Pentium M 750 (1.73ghz) 478pin socket.

What I want to know is I was looking on wikipedia (yes im aware it can be inaccurate). but is there a series of mobile dual core processors that will fit the same socket as my mobo on my laptop. I only spent about 70 quid on the GPU so another 100 pounds wont hurt.

I mean 170 pounds for a decent spec laptop is not bad you would agree?

It says the T7xxx series and T5xxx series are compatible and would fit my pin socket.

Could someone please advise me on this? Thanks!

Ps - stay tuned for my customization of my laptop im gonna do as well!

Pentium M is Socket 479.
Core 2 Duo are Socket M and Socket P.

They are similar but have slightly different pinouts, and will therefore be incompatible. Sorry, the best you can do is a Pentium M 780 (Dothan, 2.26Ghz, 2MB Cache). BTW, you have a Pentium M 740, the 750 has a speed of 1.86Ghz.

would the performance be appreciable in going for the 780? can I possibly even overclock that?

also what is better for RAM ? Crucial or Corsair they are both 533mhz and ubuffered CL4 1gb modules?

So this spec:

2gb 533mhz
X1800 256mb
320Gb harddrive

would that be quite respectable?

I have a gaming desktop but I would also like a notebook I can maybe sneak the odd game of CSS or BF2 even though I should be using it for studying for my honours in the library lol!

Imo, upgrading that CPU is not worth it. Those laptop CPUs cost more than their desktop counterparts providing you can even find it. You might how ever may want to try a BSEL mod on the Pentium M.

I recommend you upgrade the RAM to 2GB (Crucial and Corsair are both good).

I second the 2GB ram comment.
I also agree you should not upgrade the processor.

You cannot BSEL mod a 533FSB Pentium M processor, so the suggestion is null.

are you sure u cant?

I got this utility called Notebook Hardware Control which lets you change the voltage of the processor.
If i got the processor upgrade for £50 would that not be worth it? i saw one on ebay that was cheap.

The difference in CPU speed shouldn't be noticeable, but adding RAM will help a lot.

Yeah, Just checked out the specs, it is indeed running at it's max (native)FSB(533).
