cpu FSB vs RAM speed vs. overclocking please help!
Last response: in CPUs
hey
Im a bit confused about all of the numbers. I am planning on getting a gigabyte ds3 or p35c ds3 motherboard and a chip that supports 1333fsb (the new 6850 or similar when they come out). I am planning on overclocking a moderate amount but hopefully won't raise my vcore or do anything that might reduce the lifetime of the chip significantly. I bought some ddr2 800 ballistix the other day. The question is should I be using ddr1066? How does one know what speed ddr2 module they need and what are the implications for speed and performance in overclocking in ddr2 800 vs ddr2 1066 using a 1333 fsb chip (which will be overclocked). I'm just a bit confused as to how the numbers relate to each other. Should I sell my ddr2800 and get 1066?
Thanks in advance

I don't think you should. The memory clock is half of the FSB clock.
i.e. FSB = 1333, then RAM = 667.
As a result, if you overclock your CPU to 3.6Ghz from 3.0Ghz, FSB 1600 from 1333, you'll be running 1:1 with DDR2 800 (which is the best). If you want to run synchronize between your RAM and CPU using DDR2 1066, you'll have to clock your CPU as high as 5Ghz (which is not practical).
DDR2 1066, at the moment, is a little too expensive. Especially when you only want to OC within the stock voltage. DDR2 800 will be more than enough for you.
