What is the difference between DDR & DDR2?

Question

Also, are Gateway laptops any good? What is the most reliable laptop currently on the market?

Answer 1

DDR2 is newer technology and uses less power.

However, DDR2 is not faster than DDR if they both run at the same freq. For example DDR2 running at 400Mhz is equal to DDR running at 400Mhz, but DDR2 will use less power.

Answer 2

DDR2 is a newer version of DDR technology with faster speeds.
I don't suggest Gateway laptops. Most reliable are Dell notebooks (cheapest too if you buy online)

Answer 3

In digital engineering, DDR2 SDRAM or double-documents-fee 2 synchronous dynamic random get admission to reminiscence is a random get admission to reminiscence technologies used for prime speed storage of the operating documents of a computing device or different digital digital gadget. it truly is area of the SDRAM (synchronous dynamic random get admission to reminiscence) relations of technologies, it truly is one in each and every of many DRAM (dynamic random get admission to reminiscence) implementations, and is an evolutionary progression over its predecessor, DDR SDRAM. Its standard benefit is the ability to operate the exterior documents bus two times as quick as DDR SDRAM. it really is carried out via more suitable bus signaling, and via operating the reminiscence cells at 1/2 the clock fee (one quarter of the documents move fee), particularly than on the clock fee as interior the unique DDR. DDR2 reminiscence on an analogous clock speed as DDR will supply you an analogous bandwidth yet markedly larger latency, providing worse performance.

Answer 4

Try the following link for DDR & DDR2. Sorry, No idea about the second question :(

Answer 5

Ddr2 is faster in the sence that information is accessed or gained much quicker. U cannot mix the 2.

Answer 6

faster and uses less power, (NB ddr2 memory wont work in ddr slots)

Answer 7

yes gateway laptops are ok. it doesn't make a lot of difference which you buy for reliability, its who is using it, and what is the warranty. alienware is outstanding for warranty

Answer 8

The DDR2 is the second.
