Overclocking was pretty much non-existent with these kits. I'd have to state the obvious about the fact that they're already running what most people would strive to overclock a normal DDR2 kit to already. When you're talking about running 1150MHz or 1200MHz at stock settings, there really isn't any favorable gain there to hope to attain. I've tried the 1150MHz kit at 1200Mhz and it wouldn't do it. I tried the 1200Mhz kit at 1250Mhz and it wouldn't do it. At least not for me on my hardware. Could you get more out of these kits? Perhaps. But why? Getting 50Mhz or even 100Mhz more out of your memory isn't going to make ANY noticeable difference. So bottom line is these kits aren't for overclocking, they'll scorch your FSB right out the box!

Conclusion:

   Well I really don't know what else to say. This review would compare to taking a Ferrari for a spin and going "Yep! It's fast alright!". We're talking about some of the fastest memory on the market today. 1150Mhz and 1200Mhz right out of the box from a name you can trust; Kingston Technology. I had no problems running these kits in my ASUS P5B Deluxe along with an easily overclockable Core 2 Duo CPU. However in order to run this level of hardware, you'll need some high end hardware to go with it.

   If you're a gamer looking to upgrade from that 800mhz DDR2, and you've got the motherboard/cpu combo to run above specs, then either one of these new kits from Kingston Technology will do you proud. What's nice too is these kits are able to run these scorching speeds at just 5-5-5-15 timings. We've all seen the 6-6-6-18 or 5-6-6-18 stuff out there previously by other manufacturers. Kingston waited a little longer so they could do it right.

   As a last note, keep in mind that these kits will in fact run at slower speeds. For instance if you're planning an upgrade, or upgrading piece by piece and you're only able to run 800MHz DDR2 right now, these kits will do it.

   The real target of these kits is the hardcore gamer looking to squeeze out every last drip of performance from their high end machine. If that's you, you can't live without these!
