Looking at some of these sales for this friday and I thought it might be a good time to pick up some extra RAM for my system. I haven't done this before so I'm looking for guidance.

The goal add 2 gigs of RAM to my existing 1 gig for a total of 3.

I run XP pro sp2 and from what I've read this is about all it will recognize so why add more. If I'm wrong and there is a gain to be had or its just plain easier to replace the existing RAM with a new 4 gig kit so everything is the same let me know.

I'm not at my home computer right now but this is what I remember from Everest Home edition will post back later if more info is needed... which it probably will.

Clevo mother board
Pentinum 4 3.6
Current RAM 2 Patriot Memory (PDP systems) PC4200 DDR 533mhz @ 512mb

I'm not looking for the latest and greastest RAM so can I simply add more Patriot RAM PC4200 to my system or is there more to.

That should work ok. I would scan my computer online at Crucial.com to make sure there are no mistakes when ordering. Also You should check to see if your computer is running your memory in dual channel mode. If it is you will need to upgrade in matched pairs to keep the dim module numbers even and matched so you can run in dual channel mode.

I tried the crucial scan last night but I believe it is wrong. I need to look into this further any suggestions. How do I confirm if it is running in dual channel mode?

Try http://www.cpuid.com/cpuz.php , I saw where a semi-reliable source indicated that the memory section will indicate what you want to know.

Crucial show that you have four expansion slot with a capacity of 1GB of RAM per slot, the maximum amount that your system depends on whether it is the 32bit or 64bit OS. It does show that DDR2 PC2-4200 and PC2-5300.

If the RAM is populated in the proper configuration with the proper type of module you motherboard should automatically recognize the configuration and run it in dual channel. If you add more RAM you will need to match the specs of the existing modules and add in pairs. If You are going to add the new RAM modules yourself you might want to remove one of the exiting modules so that you can access the make and model from the module so that you can match the module you have, this will also give you practice in installing the module if you have never done this before. I will make one caution about static electricity, electrostatic discharge can kill a RAM module so discharge yourself before handling any RAM modules or any other card containing ICs.

Family and loved ones will always be a priority in my daily life.  You never know when one will leave you.

Just to add. You can discharge the static electricity by touching the outside of the computer case before touching any components inside. Be sure to unplug the computer from the wall even though the computer is turned off there is still power to the motherboard and a dropped screw or ram chip could kill the computer. Happy Upgrading!!

Is there an advantage in using one or the other PC2-4200 or 5300? Also whats the deal with trying to match the FSB one for one. Would either of these upgrades do that or do I need to change settings to acheive this?

Thanks for everyone's help so far.

I had not mentioned discharging to your computer as sneakycyber suggests as you are using a laptop which has a plastic case and has a great deal of built in isolation to protect it from ESDs. I would suggest touching something within reach of your work area with a substantial amount of metal to allow you to properly discharge any static electricity you have built up.

The PC2-5300 is faster than the PC2-4200, you can mix them but the faster module will only run as fast as the slower module.

You shouldn't need to make any changes if you are only installing more RAM.

if you get matching speed ram you will be able to make use of DD mode, if you mix and match you won't.

I'm just curious here Robert, what is DD mode?
