But whatever they do, the ratings they sell them for is only for ONE pair. Period. Game over, basta. Physical limitations always apply, it's simply a law of physics. They simply sell them for the higher possible rating, which is way better marketing. 1600 or even 2000 sounds a lot better than 1333, right?! That's why you BOUGHT them after all.

My 4x1 GB Corsair DDR3-1600 sticks work well, but only at 1380. Rough estimation: Two pairs of modules would only work right at the next lower clock level. Ex. 1600s at 1333 or a bit more, 1333s roughly at 1066...etc.

Please get some knowledge about electronics. Without it you will never know what you're doing....just as a general plea to overclockers!
Well, partly right and partly wrong. Striker2 Extreme can do with 4 sticks because Nvidia chipsets are known to be good in memory bandwidth.
So, partly right is that the latency you've to sacrifice no matter what you do with 4 sticks and increase in vdimm to run.
DDr2 can do much better with 4 sticks because lower latency, lower bandwdith. As you climb higher, more crucial is to maintain at such speed.
Advancement in technology will improve in due time.
Aeneon did that with 2x2Gb sticks at 1600Mhz 9-9-9-25 with just 1.5Vdimm. And is Germany technology.
