OCModShop has posted a review on the GEIL Ultra Platinum PC4000 dual channel kit

The CAS specifications of this memory are 2.5-7-4-4 which is quite slow. I figured it could do much better than that even while being overclocked. DDR500 was simple to reach with my Albatron K8X800 Pro II and AMD Athlon64 3200+. The motherboard I used does not have a DDR divider which makes overclocking more difficult. Regardless of not having a DDR divider I was able to get the RAM up to 250 FSB without a problem at all. I was even able to run the memory at DDR500 with the CAS set to 2-2-2-5 1T which is much better than the stock specifications. I pushed the RAM to the limit that my system could handle and was able to reach DDR510 and keep it stable.
