Question relating tha number of pins in a RAM?

Question

i have a serious doubt about tha pins on a RAM

i mean,

i know that when buying new RAM you need to know of wat family your RAM is

either DDR, DDR2, DDR3

but, i found out theres pins to it ?

does each family of RAM come with different pins ?

because i hear that RAMS have 72 pin

100 pin, 144 pin, 168 pin, 172 pin, 184 pin, etc etc

wat does that mean ?

do all RAM come with different number of pins ?

is tha number of pins what identify DDR from DDR2 and DDR2 from DDR3 ?

please get me out of this seriious tremendous doubt

Answer 1

In a nutshell yes, your motherboard manual will tell you what ram it can take and what pins it supports.

If you don't have the manual, you can find the specs on the net.

Answer 2

when buying a ram just take into account the voltage that ur mobo has towards ram and the nos of pins it supports and the type of ram it supports and match it with the specifications of the RAM ..

If they match there is no way u'll spoil the mobo...

if ur not aware do consult a tech person...

Answer 3

SDR has 168 pins and two notches.

DDR has 184 pins and a single notch.

DDR2 has 240 pins and a single notch.

DDR3 has 240 pins and a single notch, but the location of the notch differs from DDR2's notch location.

Each of those are a type of RAM. SDR is single data rate. DDR is double data rate. DDR2 is the second generation of double data rate. DDR3 is the third generation of double data rate.
