Determining whether you have DDR1 or DDR2 RAM is crucial for upgrading or troubleshooting your computer. DDR1 and DDR2 are two different types of memory that are not interchangeable.
DDR1 was the first type of DDR memory, and it was released in 2000. DDR2 was released in 2003, and it offered several advantages over DDR1, including higher speeds and lower power consumption. DDR2 is no longer used in new computers, but it is still found in many older computers.
