My ram is reading as PC2-6400 o_0

Whether 1066 MHz memory speed is supported depends on the CPU being used

The part number indicates that it's a 1066Mhz kit. Unlike some 1066 kits, it will work at 800Mhz and 1.8V. For 1066Mhz, you have to set the timings and voltage manually. The motherboard can only report what's available in the SPD and the maximum is 800Mhz.

No if its adversisted at 1066MHz then that is the speed that they were designed to reach.

Some motherboards automatically see it at 1066 but most only see it at 800 and you have to set it manually to 1066 through the bios, by increasing the voltage. If you go to the manufactures site it will show the voltage it needs to be set at to reach that speed.

Yeah, they are all right. DDR2 800Mhz is the highest 'official' speed for DDR2. Though it is possible to make DDR2 chips that can reach higher speeds like you DDR2 1066 all the way up to DDR2 1200MHz.
You will have to 'overclock' you memory manually to 1066MHz. It should not be difficult though, because these chips are made to run at 1066 MHz 24/7. Read the specs sheet from OCZ about you ram and check out at which timings and voltage it should run when set to 1066MHz. Set all of these manually in the bios of your mobo. You should be just fine.
