RAM transfer rates of DDR2 533

[2048Megabytes]

I was reading on a my A+ Certification trial exam, it states the approximate transfer rate of DDR2 533 is 4266 Mbps. This means 4266 megabits per second.

This is incorrect from my understanding. The transfer rate is 4264 megabytes per second. I am correct aren't I? Megabits per second would mean the transfer rate would be only 533 megabytes per second. A small b in Mbps means bits not bytes. The small b is a typing error isn't it?

It appears that you are correct and that it was a typo. When you talk in terms on PC-XXXX ram, that is the transfer rate. PC-4200 or DDR2 533 transfer rates are 4266 MB/s, PC-6400 or DDR2 800 transfer rates are 6400 MB/s, etc.
