While testing the ASUS Blitz Extreme board we had a chance to test the latest Patriot 2GB DDR3 Kit called PDC32G1333LLK, which comes with two 1GB modules.
This Kit comes with the typical Patriot heatspreaders, it's rated at 1.7V, nothing special for a 1333MHz kit. The timings are quite standard, CL7-7-7-20. During our tests the heatspreaders did not heat up much.
While low latencies do not imply it will run faster than the higher ones, it all depends on the mainboard you are using. The ASUS P5K3 Deluxe could run faster with CL9 and Boost 3, while the Blitz Extreme refused to run faster than Boost 0, but had no troubles using CL7.
The memory is rated at 1333MHz and overclocking depends on the mainboard. Our ASUS Blitz refused to run with 1500MHz, even with higher voltage, relaxed timings and deactivated boost.
[Update: October 7h, 2007]: We managed to run with 1500MHz, it was a bit tricky but it is possible :-)
We run all standards test with AUTO settings, but for our last bench we tweaked the BIOS. If you don't know what you are doing, you should avoid BIOS settings as it may ruin your Windows installation during booting. We are sure this kit could do better with other boards or more tweaking, maybe a new BIOS would help, too.
