Ram overclock to 1866MHz

Yes, in the vast majority of cases, you have to set it in the BIOS, unless you have a particularly clever BIOS!

Usually they bin memory pretty accurately, if it's 1866mhz chances are remote that it could hit 2000mhz or they would sell it as such.

well yes and no .. i have sniper low v mem (1600) and it runs quiet well at 1866 and even a little higher ..relax the timmings and it will go higher 9.9.9.22 to 11.11.11.30 will get a lot more out of it

I saw an article recently on the real world differences between ram speed, with I had a link.
Basically said that the jump from 1333 to 1866 was noticeable and that 1866 to 2400 was noticeable but that it was more quantity than speed that made the most difference.

So me going from some old DDR3 533 MHz with a Core i7 920 to a new Haswell system with DDR3 at 1866 MHz should see a noticeable increase in program performance?

The 533 stuff is really 1066, there should certainly be a measurable difference but nothing huge.
