Calculating Ram Bandwidth

[ADVgamer]

Alright so... I need someone to tell me if my Calculations are correct. I am trying to figure out how to calculate Ram Bandwidth, this is what I came up with...
Alright so here's how I calculated my ram bandwidth:

I have 4GB of Kingston HyperX ram clocked at 1066Mhz, 2 sticks.(DDR2, DUEL CHANNEL MODE!)
I am running Windows 7 Ultimate 64Bit.

The formula that I ended up with is:

"Ram Frequency" x "Windows Bit Architecture"
---------------------------------------------------------------
8Bits

"1,066,000,000 Hz" x "64Bits"
-------------------------------------
8Bits

With that formula I calculated a speed of 8,528MB/s... The thing I don't get is, should I double that because I have 2 sticks of Ram running in Duel Channel mode?... In which case I end up with about 17,056MB/s

Are you calculating practical or theoretical limits?

Practically speaking, RAM bandwidth is limited by any number of factors. Chipset, memory control unit, processor memory caching speeds, etc.

The sounds about right ADVgamer. You can use http://www.memtest86.com/ and it will show you your memory bandwidth during the benchmarks.
