Just need it clarified with some references if possible, when I buy 2GB DDR2 RAM. Is the GB measured as gigabyte or gigabit?

They use 1024 mebibyte Gibibytes (what we classically consider proper megabytes and gigabytes) (unlike the metric gigabytes hard drive manufacturers use)

amm.. do you have any technical references? I would like to understand this better.. thanks for you inputs – rzlines Apr 7 '11 at 9:34
1 wikipedia would be a start - there's further references there. I refuse to call the 1024 gigabytes gibibytes, personally. – Journeyman Geek Apr 7 '11 at 9:46
Personally, I think the "classically" considered "proper megabytes" are just wrong. Everything with a kilo prefix means 10^3 not 2^10. The kilo-meter, the kilo-gram, the kilo-watt. And these multiples of these units were defined way before the computer era. – Radoo yesterday
In this case tho, the 'classic' definition is the source of confusion and it feels like a convenient way to explain the issue – Journeyman Geek yesterday

Gigabyte. Gigabit is generally used as a unit in video game ROM size, and in network speed, and should generally be Gb, not GB.
