Mixing Ram

that great...but I was talking about memory errors and things like that. Thanks though for copying something from wikipedia..../sarcasm over

Just want to correct this. If we are talking about types, we're pointing about DDR, DDR2, DDR3, SDRAM and so on. Mixing two different types of RAM is impossible. If your motherboard supports two memory types of RAM then you can use only one type of RAM. You can't install two types of RAM simultaneously because it will create a error or worst burn.

Maybe you're talking about the brands, capacities and frequencies of RAM. Yes you can mix different brands, capacities and frequencies as long your motherboard supports it.

Examples:
Example 1: It's ok to mix DDR2-533(266MHz) and DDR2-800(400MHz), but I will not recommend this because the frequency of DD2-800(400MHz) will down clock to the frequency of DDR2-533(266MHz). That will not help your computer operate faster.

Example 2: It's ok to mix DDR2-1066(533 MHz) and DDR2-800(400MHz). I will recommend this because the frequency of DD2-800(400MHz) and the frequency of DDR2-1066(533 MHz) are just close. This will help your computer operate faster.

You can see the DDR2 frequencies --> HERE

Did you already get it?

You should read my examples. Then you get the answer about your "Recommended".
