SuperPI 8M times with E6600@3G=333.3x9, on both P5K-D and P5K3-D:
DDR2-800,CL5 -> 3m28.250s
DDR2-800,CL4 -> 3m24.625s
DDR2-800,CL3 -> 3m23.234s
DDR2-1066,CL5 -> 3m21.953s
DDR3-1066,CL7 -> 3m25.531s
DDR3-1066,CL6 -> 3m22.782s
DDR3-1066,CL5 -> 3m21.875s

...sorry in Japanese language
Notice:
In my experience, P5K-D is faster than P5B series booted at over FSB401(=FSB1333 strap?),
but it's a bit slower than P5B series booted at below FSB400(=FSB1066 strap?).
So, I'm waiting BIOS update and faster DDR3...DDR3-1333 or more...

DDR3 Memory Modules Ready To Launch This Month
.......
With upcoming 333MHz FSB processors running DDR3 memory modules at 1333MHz will be a standard setting in the BIOS. To hit 1600MHz a FSB of 400MHz needs to be reached, but that is not tough to do as it would be a mild overclock. DDR2 memory modules on the market right now have been topping off around ~1320MHz, so DDR3 is starting off at the upper limits of where DDR2 starts to become unstable.
When it comes to performance for enthusiasts and gamers it seems the DDR3 kit that you should hold out for is the DDR3 1333MHz memory kits. It seems that DDR3 memory kits start to strut their stuff at speeds above this, so don't expect to see impressive performance numbers beyond till modules reach this frequency and beyond. From what we can tell not too many modules can even hit 1500MHz with good yields. It seems that the memory companies are still sorting all the memory IC's and are in the mist of figuring out if Micron, Eplida or Qimonda IC's are the best to use. It seems that Samsung IC's aren't doing too hot, so don't expect to see those on many of the first enthusiast modules.
When it comes to memory timings the initial 2GB kits of DDR3 1066MHz memory modules are mainly using 6-5-5-15 timings and the 1333MHz modules are running 7-7-7-20 timings. Once again it seems 'aggressive' timings is a thing for the past as when DDR2 first came out CL5 and CL6 parts were seen out at about in the early days. While many will baulk at the high timings keep in mind that DDR3 has 8-bit pre-fetch architecture (compared to 4-bit pre-fetch buffer with DDR2 and 2-bit on DDR1), on-die termination (ODT), power-saving modes known as PASR (partial array self refresh) and ASR (auto self refresh) and other capabilities. With the improved pre-fetch architecture alone it makes it hard to compare DDR3 to DDR2 when it comes to timings as the modules do more per cycle.
Love it or hate it, numerous brands of DDR3 memory and Intel Bearlake (P35) chipsets are built, packaged and ready to be placed for sale in the weeks ahead. The question now is who will have the first dual channel 2GHz memory module?
