Back in the day, I read it was better to run memory that was synchronous to your FSB. So I got DDR 400 for my Athlon X64 4800+, then a while later I got DDR2 800 for my Q6600. I happened to drive by the NJ Microcenter last weekend on a family trip, so I stopped in and got a couple of i5 3570K, with the Gigabyte GA-Z77x-UD3h boards. Now I need the rest...

I don’t know what to call it now with the memory controller on chip, but I think the “FSB” is 100 on the i5 3570, so is DDR3 1600 the right memory to get???

The strap meant the ratio right?

For instance:
1:1 = 800fsb and 800 on memory
1:2 = 400fsb but 800 on memory
2:3 = 666 fsb but 999 on memory closk
4:5 = 1600 fsb but 2000 on memory clock

The memory controler is on the cpu and it doesnt care if you run 1600/1866/2133/2400 as long as the memory can handle it.

Just get 1600 cause there is very little difference and 1600 is in the middle of high performance and basic. I use the samsung low profile eco green 1.35v memory but as you cN see in my sig, it runs a lot faster than that if you want to overclock it.
