Native PC2-8500 1066MHz memory ?

For the researches that I have done so far, it looks like that all memory DDR2 PC2-8500 1066MHz will show up as 800MHz unless manually OC.

Does anyone know why there isn't native memory at 1066MHz?

Reviews from Newegg.com and Tigerdiret.com on many different PC2-8500 report that the memory is often unstable at 1066MHz. Some users run them at 800MHz to avoid BSoD or other problems.

What seems to be the problem with PC2-8500 memory?

PC2-8500 is seen as native PC2-6400 from the BIOS. Does this means that the current memory I currently own (PC2-6400) can be OC to PC2-8500 1066MHz?

I don't see any logic behind this, because I am not a memory expert. Could someone bring logic into this topic?

Thanks in advance

Q - "Does anyone know why there isn't native memory at 1066MHz?"
Real Q - "Does anyone know why the MOBO doesn't support native memory at 1066MHz?

ANS - Well the primary reason is the chipset used by your MOBO has a Memory Controller limited to 800 MHz {nForce 680i LT SLI} - http://en.wikipedia.org/wiki/NForce_600#nForce_680i_SLI

BFG Tech BFG680i SLi LGA 775 + DDR2 is 800 MHz, but some LGA 775 MOBOs also utilize DDR3 with 1333 MHz depending upon the chipset. The fastest 'Rated DDR 2' is 1200 MHz.

So the Motherboard seems to be the problem, not the memory. Thanks, now I understand the memory issue.
