I'm planning to stock voltage overclock my i5-750 to around 3.3ghz. I have a hyper 212+.

Which memory speed to choose? 1600 or 1333?

I want to get this one, but is expensive.

I rather get this one, with a combo deal.

So would 1333 make much difference? I know technically speed wise wouldn't make much performance difference, but would it effect the overclocking? Like the 1:1 ratio?

I always think a memory ratio of 1:1 is more stable, but thats just my preference. I have no evidence to support.

Maybe another option, is that you buy the 1333 and overclock to 1600, BUT could be dangerous for the RAM.

Would 1333 be enough for 1:1 ratio? cause i really don't understand how you calculate it even after researching it.

I don't mean to hijack - but how do I match RAM with CPU nowadays?
I'm thinking to build a Core i5-750 too, OverClock not planned.

From intel core i5-750- Processor Base Frequency 2.66 GHz
Supported Memory: 1066/1333

So...I don't even know what to ask,
What ram should I get?

edit:
Since the core i5 memory controller support dual channel
I should get 2x DDR3 1333?
So what are those 1600/1800 or 2133s for?
Overclock? (that's assuming you overclock by up'ing the base frequency, right?)

And for the i7-950, listed bus frequency 3.06 GHz
It's triple channel supporting 800/1066
How do they play together?

Not to mention AMD phenoms...
I'm lost and got no clue at all...
