I'm pretty new to all this. I'm building a system with an Intel P975XBX2 motherboard and E6600 (Core 2 Duo 2.4 Ghz) CPU. I may eventually upgrade to the Quad Core 2.4 Ghz when the price comes down.
The Intel (and Asus) motherboards are rated as 1066 FSB. However, the same Intel (and Asus) motherboards list the RAM spec as 800. I'm confused. Explanation would be greatly appreciated.
Along that line of thought:
Would it be "overclocking" or "standard procedure" to use the DDR2 1066 RAM?
Will the 1066 give me the better performance that I expect from it at stock settings / no overclocking?
I'm under the impression the 1066 (even though it operates at 2.2 volts) will give me some breathing room if I choose to overclock, is that correct?
Many thanks, for all the guidance everyone has provided over the last couple weeks

I don't believe the mobo supports PC8500 (DDR2 1066) RAM. See below for link and info from Intel website regarding RAM for 975XBX2.

Thank you very much for catching that, I completely missed it. Unfortunately, the Asus also doesn't seem to support 1066 RAM

Dual channel memory architecture
4 x 240-pin DIMM sockets support max. 8GB
DDR2 800/ 667/ 533 ECC and non-ECC memory
I'm curious, why is the DDR2 1066 being manufactured right now? Is it for the SLI boards?
Thanks again

So if I understood right, you're saying it's okay to run the 1066 RAM? The motherboards I'm looking at both have a 1066 FSB and are rated at 800 for RAM.
Will the system constantly be overclocked if I use the 1066 RAM? I'm not sure I'd want to run it overclocked 24/7.
On the other hand, does the 1066 RAM have more overclocking potential than the 800 RAM?
Thanks again

So if I understand correctly, since the FSB on my E6700 is 1066mhz I could step up to PC8500 (DDR1066) and it would run faster memory speeds than my existing PC6400?

Well not quite!
With an Intel Chipset you will top out at 800 MHz for memory and if you over clock about 930 - 1030 MHz is about where it will top out.
You have to remember that DDR1066 is running at 533 MHz actual clock frequency and A Intel 1066 FSB CPU is actually running at 266 MHz actual clock frequency.
