Hi all

Will a graphics card with DDR3 SDRAM memory be compatible with a motherboard that uses DDR2 memory?

Any replies much appreciated

Short answer yes, if the connection is the same as the port resident on the motherboard.

On this topic. I have one question.

There are vga cards which have GDDR3 or GDDR4, what does that mean exactly?

DDR = Double Data Rate. This type of memory generally refers to RAM.

GDDR = Graphics Double Data Rate. It is the same thing, but is situated on the video card. GDDR memory is dedicated to processing and storing graphical data.

In each case the higher the number (DDR3, DDR4 etc) means a new and improved version. DDR was the first, while DDR5 is the most recent. An easy way of thinking about it is to think of each type as just a different version, eg. Double Data Rate Version 2 or Graphics Double Data Rate Version 4.

In any case they are just Random Access Memory.

You can have any Version of GDDR memory on your card and it will be supported by the motherboard, while DDR memory needs exclusive motherboard support.
