Figuring out RAM clock speed

Arbi sends us word on his method of calculating the speed of unknown ram....
"...it is
important to look at the last two numbers to find out the chip speed.
A lot of times at computer shows people will charge you a $5-10 premium for
a PC133 piece and you look at it and the digits end with an 80.
I can never remember what nanosecond rating correlates with what speed, so I
just use the following rule. Take the number 1000 and divide it by the ns
rating.
1000/10 = 100 = 100mhz
1000/8.0 = 125 = 125mhz
1000/7.5 = 133 = 133mhz
1000/7.0 = 141 = 141hmz and so on
This might be of use to overclockers who don't always run their systems at the typical bus speeds - I'm not sure.
However, as with a lot of chips, the speed printed on the chip does not
necessarily mean it won't work at other, potentially higher speeds..." Thanks for the tip!
