:grin: I'm sorry Clare,

Your Motherboard, that way we can verify how much and what type of RAM your computer can handle.

Hope this is ok!

:smiley: OK! Super,

Here is what your computer can handle

Memory:
2 x 184-Pin for PC1600 (DDR200) or PC2100 (DDR266) unbuffered DDR SDRAM memory
with 100 or 133MHz clock frequency up to 2GB capacity


If this doesn't make sense to you, print it and take it with you when you go to purchase your RAM, they will be able to help you.

Best rule of thumb is whenever possible, max out your RAM.

Does that make sense?

Look forward to your reply,

Could you just make it a liiiiil bit clearer, sorry!!!

:cheesy: Memory is confusing, LOL. So let's do a Memory Primer

OK here we go memory comes in lots of different types and sizes. It is more than just megabytes. If you don't purchase the right type of RAM it either won't fit or could burn out your Motherboard.

Here is the break down.
Your computer uses;

2 x 184-Pin - that's the description of how the little pins that sit into the sockets are laid out.

PC1600 (DDR200) or PC2100 (DDR266) - these designate the work of the particular type of memory

PC1600 SDRAM: This is Double Data Rate SDRAM that doubles the transfer rate of PC100 SDRAM to 200 MHz. The reason the notation doesn't say "PC200" is because the 1600 denotes the total bandwidth the memory is capable of. In this case it's 1.6 GHz of bandwidth.

PC2100 SDRAM: This is Double Data Rate SDRAM that doubles the transfer rate of PC133 SDRAM to 266 MHz. The notation means this memory has an effective bandwidth of 2.1 GHz.

unbuffered DDR SDRAM memory - this is the type of memory it is effectively included in the descriptions above.

100 or 133MHz clock frequency - this is the speed of the memory it can handle

up to 2GB - this is the maximum amount of RAM this Motherboard can handle.

Which is why it is important to bring the description with you if you are going to purchase RAM in a store. If you are going to purchase online, make sure the retailer is reputable, and simply match up the descriptions.

Does that make it any clearer?

Look forward to your reply,
