Choosing a correct processor

There's one faster CPU in that line (3600+), but it has a smaller cache - meaning it wouldn't be much if anything of an upgrade.
Maybe upgrade the memory, that would have a better return, if it will take anymore.
Put the funds toward a newer system.
Hope that helps you to save some cash.

Your socket is AM2. You can put any AMD processor that has AM2. If the processor is AM3 just upgrade the bios of your motherboard and it should work. If you need further assistance, just leave a comment. Cheers

Hi Paul,

Correct, you have to use the same type, but you can upgrade to a faster CPU.

According to the specs for your computer it can take the following:

AMD Sempron processor 2600+ to 3300+, 333MHz FSB
AMD Athlon processor 2800+ to 3200+, 400MHz FSB

See:

The Athlon's are better...faster Bus. The Sempron is cheaper.

The 2 processors you describe are very similar. The difference between the 2 is that the first one is capable of running 64-bit operating systems and applications. The second one is strictly for 32-bit systems.

The next question will probably be, "What do I have?" Probably a 32-bit system. You can go with the 64-bit CPU and be safe as it can run both. You can see what your old one is by the revision number on the top of the CPU. You can use the following comparison chart to see the differences:

I hope this has been some help. Maybe it has just caused more questions. Just ask.

Thanks for using Fixya.

please purchase the processor that is compatible to your motherboard. if the motherboard can be upgrade to a higher speed of processor then purchase it. if not, stick to the required specs. if you still want to upgrade, replace the motherboard, processor and the memory.

The faster speed is the slowest device on the network.
YES, YES, YES
yo need RAM upgrade. for what the CPU is running (1.8-2.00GZ).
Since I don't know what operating system you are running. upgrade the RAM to 2GB should definitely spped up your Internet Access.

The AMD Phenom x4 is actually cheaper with 4 cpu cores compaired to Core 2 duo which has 2 cpu cores, you will get a better deal for less money on a AMD x4.

Heres a chart you can look at
http://www.tomshardware.com/charts/desktop-cpu-charts-q3-2008/3DMark-Vantage-CPU,817.html

I just got myself the AMD Phenom 9650 for 150usd
The core 2 duo e6600, which I would recommend from the core duo series costs around 200 usd.

Note that the Duo only has 2 cpu cores. You get double the power on a phenom 4x with 4 cpu cores
So the phenom is definitely the best choise! (double the power for 50usd less)

Anything else?

You motherboard uses a "Socket A" CPU and therefore has limits to how high you can go.. I would recommend the XP 2200 or 2400+ as a good choice, but you can make your own choice.

To upgrade your system with AMD 3000+ sempron processor is a little bit difficult. AMD 3000+ requires a new motherboard that may not be compatible with your laptop. So I suggest you to get your laptop exchanged with a new one with the above.

Your processor speed is actually correct AMD calculate the clock speeds differently from Pentium type processors, a 3400+ is a 2.0 GHZ processor, see the list below for speeds Sempron 2500+ 1.40 GHz 800 MHz 128 KB 754 Sempron 2600+ 1.60 GHz 800 MHz 128 KB 754 Sempron 2800+ 1.60 GHz 800 MHz 256 KB 754 Sempron 3000+ 1.80GHz 800 MHz 128 KB 754 Sempron 3100+ 1.80 GHz 800 MHz 256 KB 754 Sempron 3300+ 2 GHz 800 MHz 256 KB 754 Sempron 3400+ 2 GHz 800 MHz 256 KB 754 Don't worry too much about the proceesor not being recognised as long as you know it is running at the correct speed.
