Aight,
I have been trying to figure this out for months. I have not been doing much or keeping up on the computer field of my life for a couple years but I am trying to get back into it since its something I have fun with.
But im getting agrivated already! lol
Im trying to find out what memory type (DDR333, DDR400 etc.) I need and why.
I was looking at MSI motherboards and the have a board that is capable of seeing a FSB of 1 Ghz, 2000 MT/s. Now this is where I get confused. I dont even know how to word my question.
For some background on a motherboard with this FSB
http://www.msicomputer.com/product/p_spec.asp?model=K8N_Neo4_Platinum&class=mb
How can I figure out what speed of RAM I need? If I have a MB with 1ghz FSB. I figure I would need 4 DDR500 Chips on a dual channel to equal the 16000MB/s Transfer rate you would see with a 1ghz FSB.
My Math
1000 (1ghz FSB) x 2 (Cycles per clock) = 2000 (MT/s)
2000 (MT/s) x 8 (Bus Width) = 16000 (MB/s transfer rate).
so with this math. Would I need 2 pairs of DDR500 runnign dual channel to reach the 16000 MB/s transfer rate (bandwidth)?
500 x 8 = 4000
4000 x 2 = 8000 MB/s (2 DDR500 chips running 2 channel)
8000 x 2 = 16000 MB/s (4 DDR500 chips running 2 channel)
MSI boards only go up too DDR400 which in my math world would only equal to a total bandwidth of 12800 MB/s. Seems slower then the total Bandwidth capable of the motherboard.
Am I thinking totally backwards or to far to the left ? I know im not thinking something right.
Now with the Intel 800mhz FSB. Most (if not all?) Motherboards used dual channel DDR. So they would use 2 DDR400 to equal the 6400 MB/s transfer rate you would see with the 800mhz FSB.
800 x 8 = 6400 MB/s
DDR400 = 3200 MB/s
3200 x 2 = 6400 MB/s (Pair of DDR400 running Dual Channel)
NOW, I am so confused its not even funny. Im reading the Upgrading and Repairing PCs book by Scott Mullers 16th Edition and its not adding up. Page 472 is confusing me when I put it into the real world.
Like I said. I dont even know how to word my question and the answer is probubly alot easier then im making it to be. Can someone fill me in?
Tell me how im supposed to figure this out?
Thanks alot guys/girls
