Dell Latitude C640

Does anyone know if u can upgrade the processors on my laptop as i am thinking of buying another processor for it as the one it has is a bit to slow for me to multi task

 

your best bet would probably be to buy a new laptop

 

dont have the money to fork out for a new one at the moment as i got this laptop very cheap

just wondering if i can upgrade the processor in side it

 

The reason why multitasking is so slow is probably because of the amount of your memory. I believe if you were to increase the amount of RAM you had and not upgrade the CPU, I honestly believe that you would see a greater increase in performance. 512 MB is not nearly enough for many of today's applications, even for Windows XP. Currently, your operating system must have a pretty large page file on disk that constantly swaps between disk and memory. As you know, the disk is much slower than the RAM, so swapping the page file and memory is a relatively slow process. By increasing the amount of RAM in your computer, you would see better performance in multitasking since more programs can be held in the memory at one time without spilling over to the hard drive's swap file for more space.

 

ok thanks for that

i guess ill buy 2 1GB ram cards hopefully they will fit in this laptop

 

You can upgrade to any of these processors:

Pentium 4-M 1.9 1900 512 400
Pentium 4-M 2.0 2000 512 400
Pentium 4-M 2.1 2100 512 400
Pentium 4-M 2.2 2200 512 400
Pentium 4-M 2.3 2300 512 400
Pentium 4-M 2.4 2400 512 400
Pentium 4-M 2.5 2500 512 400
Pentium 4-M 2.6 2600 512 400

The fastest processor here, the 2.6GHz chip (SL6WZ), is about $50 on eBay and it may actually give you a small, but noticeable performance boost. The upgrade in memory will probably help more, though.

 

what one would be best for me as i dont know much about laptops as ive only used desktops and will any of them work in this laptop?

 

All of these will work, but only you can determine which one is "best". The 2.6GHz chip might be the fastest, but maybe $50 is too much for you. The 2.5GHz chip will give you a bit less performance, but may be a bit cheap and so on and so forth.

 

Intel Pentium 4 (M) CPU - 2.66GHz - SL6DX

i just foiund this on ebay would this processor work on this laptop?

 

Nope. The C640 doesn't support 533MHz FSB processors. Like I said, those eight are the only processors to which you can upgrade. There ARE other processors that will WORK, but they are either slower Pentium 4-M or Celerons.
