From Tom's article on overclocking the E2160.

"There is a nice advantage to accelerating the FSB speed within the capabilities of the motherboard, or only slightly beyond (355 instead of 333 MHz), which is the modest overclocking of the memory. The DDR2 RAM operated at DDR2-880 speed. Although it didn't cause any problems, we decided to increase the memory voltage anyway, just as a precaution."

I thought DDR2800 could operate with a clock frequency of 400mhz so isn't increasing the FSB to 355Mhz also increasing the memory speed to 355Mhz? How is the ram being over clocked?

I am a newbie trying to learn all I can before purchasing hardware. I would be very happy to overclock a E2160 to just 3.0ghz as long as it ran very stable at reasonable temperatures and not excessive power loads over stock speed. The pc will be on sometimes 24/7 for days on end. At that speed can I do so with cheap regular DDR800 ram?

Correct me if im wrong, but if the memory is not set to 2.0 (1:1 ratio) but rather 2.5 then the ram would be overclocked (355 x 2.5 is about 880).

If it was 2.0 it would be 710 (2 x 355=710) and underclocked

It seems it might be that way although I don't see where it says so in the article but I thought for overclocking, you wanted to keep the FSB and memory bus at a 1:1 ratio.
