Can You Mix Different-Capacity DDR Memory Modules?

Can you mix different capacity DDR memory modules? The simple answer to the question is yes. The biggest thing to remember is that the DDR memories must be the same type. Unless your motherboard specifically allows DDR2 and DDR3 mixture, you must use one or the other. If you have a 1GB DDR2 you can mix it with any size of DDR2 memory stick. But, if you have a 1GB DDR2 and 2GB DDR3, they will not mix. You can use the memory type that is compatible with your motherboard as a guideline.
Can You Mix Different-Capacity DDR Memory Modules?

When answering the question “Can you mix different capacity DDR memory modules?” you need to consider the speed of the memory modules. You can get various forms of DDR memory at different clock speeds. As long as you do not mix different forms of DDR memory, you can mix DDR memory with different clock speeds. You might have a DDR2 with a bus clock speed or 200 and another one with a bus clock speed of 400. They will work just fine. The only drawback is that the motherboard will use the lower clock speed to access memory. So, that means it will clock at 200 MHz, not the 400 of the higher speed chip.

Upgrade Your Computer with an External Hard Drive

When you run out of storage space on your hard drive it doesn’t mean that it is time for a new computer. When you need to transport large amounts of information you don’t have to burn a stack of CDs that get out of order and require extra time to access. An external hard drive is portable and can implement your computer by a terabyte. They work for both PC and Mac, desktop and laptop. Every computer of any size can accommodate at least one portable hard drive. And some systems that have multiple ports can have several of them.

External HDD

There are several types of external hard drives. The desktop model requires a separate power adapter and though it can be transported from place to place, is designed to be on top of a desk where it has access to power.



Drives for laptops are designed to draw power through the connector cable whether it is plugged in or running on battery power. These "pocket drives" are small enough that they fit into the palm of your hand or in your pocket, purse, or briefcase. Some are so small you can stuff it into your pants pocket.
