In fact, this is how some motherboard manufacturers get higher benchmark figures--by overclocking the system slightly. So your 1000 MHz PIII might be running at 1003 MHz in one motherboard and 1001.5 MHz in another motherboard, and 998.5 MHz in still a third motherboard.

It's easy! Just remember that DDR333 is double the actual clock speed (166MHz) because it's "Double" Data Rate memory, and that it's equivalent "PC" number is 8 times that, or PC2700 (more or less.)

Well, PC66, PC100, and PC133 all refer to the clock speed of the bus driving the memory. 66 MHz, 100 MHz, and 133 MHz. After that, sanity departs. You see, along came RAMBUS, which uses a much higher clock (600 MHz or 800 MHz), but with a much narrower data bus (8-bit, I think). So RAMBUS could advertise PC800 RAM, which fooled stupid people into think that PC800 was eight times better than PC100. So the SDRAM camp decided to come up with a designation that measured the "memory bandwidth", resulting in designations like PC1600, which fooled stupid people into thinking that PC1600 was twice as better as PC800 RAMBUS. (Smart people like you and me just go, "WTF is with all these numbers?!?") For the record, PC400 and PC800 are RAMBUS RAM (RDRAM), which is evil. PC1600 is DDR with an actual clock of 100 MHz and an effective clock of 200 MHz. PC2100 is DDR with an actual clock of 133 MHz and an effective clock of 266 MHz. I am not sure on the DDR300 and DDR333 stuff, other than to say that I have heard rumor that some of it is just overclocked DDR266.
