I also thought the timings was pretty nice on it for the price, I mean with AMD CPU the timings mean more than just raw max mhz in the ram - there are better timings from what I saw in their titanium series, slightly, but at nearly 2x the cost.
From what I can tell the EPP thing is to make overclocking simpler and easier to those of us who aren't as versed in all the finer details of the matter, but am unsure if I'm missing any points of this matter or not.

""Enhanced Performance Profiles
Last week NVIDIA and Corsair announced that they have collaborated on a new open standard memory specification called Enhanced Performance Profiles (EPP). As some of you may know, AMD has pretty much taken care of the memory controller since the introduction of the Athlon 64 family, and that will not be changing for the AM2.
The purpose of EPP is to make tweaking easier for, erm, tweakers. Provided you have a nForce 590 or 570 SLI based motherboard, the BIOS will detect the memory and prompt the user to enable the built-in optimizations. If you're guessing that this sounds like detecting Serial Presence Detect (SPD) settings, you would be partially correct as EPP is an extension to SPD. As NVIDIA explained to us, Corsair uses the extra space in the SPD region of memory to hold the extra EPP settings and the NVIDIA BIOS contains code to read that information.""
""By default, SLI-Ready Memory is disabled. While NVIDIA and Corsair have done extensive testing, overclocking is always a case of your mileage may vary. Provided your memory is indeed SLI-Ready certified, you'll have a number of options once enabled. Disabled, any memory clocked at 800MHz and up will run at 800MHz. CPUOC0% runs the memory at 936MHz. Note that at this speed, as the setting implies, there is no CPU overclocking. Each increment thereafter will increase the CPU overclocking by the specified amount.
NVIDIA's tests have shown about 15% improvement in SiSoft Sandra and 4% in games such as Doom 3 using CPUOC0%. While overclocking memory isn't new, EPP makes it much simpler and less tedious than it has been in the past. Still, nothing has been removed though and enthusiasts wishing to do things the old way can still do so.
While this is a joint development between NVIDIA and Corsair, the EPP specifications are open standard as mentioned earlier, and expect to see other memory manufacturers to release products with EPP support, such as Kingston and OCZ.""
I don't claim to be any type of guru, I know a few things, but I know there is a lot to understand. Never heard about any of this before today and looking for help in getting a more in depth view of what it all means.
