PS. Sometimes you will find that the memory sold as 800 MHz is only
recognized and runs as 667 MHz unless overclocked. This can be seen in the
BIOS also.

Again, if something is sold as PC2-6400, it should be corrected rated to run
and 800MHz. Anyone selling PC2-5300 RAM as PC2-6400 RAM on the basis of
overclocking is breaking the law.

However, official DDR2 RAM speeds only go upto 800MHz, so DDR2 RAM that has
a higher rating is outside the official standard - I'm not sure in this case
what SPD information is stored in these chips... is it the highest official
rating (PC2-6400) or its actual rating (PC2-1066 for example).
