Well if that is your requirement then these are the best for you.http://www.newegg.com/Product/Produc...82E16820231032
I dogged this sticks at first but when my HZ arrived I realized I'm maxing out my mboard anyways so I've found the ZX to be best for me and I even have them slightly OC'd.
Stock speeds are 2-3-2-5 which is pretty much as good as it's going to get at stock speeds with 2x1gig.
Again, these are good for a slight OC as well, 2.5-2-3-5 @ 225mhz isn't bad and they can get up to 235-240 around those timings so again, not a bad overclocker as well.
Looks like you'll break even on price also from your refund.
