Yes, RAM dividers will help if you have cheap RAM, which it looks like you don't have
. Corsair 3200C2 is some pretty good stuff. Look at the sticker on the chip and see what revision your RAM is. This will tell you what kind of chips your RAM uses.

Basically, you want any of the Winbond chips or Samsung TCCD/TCC5 (Brainpower PCB also helps, but not by much). Mosel Vitelic is crap and I have no experience with Infineon.
Winbond CH-5/CH-6/BH-5/BH-6/UTT ---> these love a lot of voltage (typically around 3.3 - 3.5 volts) and can do DDR520 (260MHz) and beyond with tight timings of 2-2-2-5 (I think the record is around DDR580 at timings of 2-2-2-5, but that was with a whopping 3.8 volts
and some massive cooling). These chips have become scarce, but there are still some of them left.
Samsung TCCD/TCC5 ---> a lot of bandwidth can be squeezed out of these (typically more than DDR600 or 300MHz) on low volts (nothing over 3.0 volts or you'll FRY these), but with looser timings than Winbond chips. You'll need CL2.5 for anything over DDR440 (220MHz), but CL2.5 is enough to get you over DDR600 (300MHz). Samsung recently stopped binning chips for TCCD, but they kept manufacturing the same stuff. TCC5, which is binned at lower standards than TCCD, now encompasses what TCCD used to be and what it already is, so basically you might be getting chips binned at TCC5 that can really perform more like TCCD, but real TCC5 doesn't perform much worse than TCCD, so you're basically in the same boat with either.
