what's the difference between "Simm" or "Dimm" Memory?

Question

and how can i tell which type my PC uses without taking it apart ?

Answer 1

The easiest way to find out what kind of memory you have is to use http://www.crucial.com and run the memory scanner to tell you what kind you need.

Make sure you pay attention to the other monikers, as most memory is not listed as "DIMM" anymore because all of the memory these days are "DIMM".

You need to know the type (SDRAM, RDRAM, DDR, DDR2) and the speed (PC2100, PC3200, or 266mhz, 333mhz).

Answer 2

hello..

As far as I can remember, the SIMM memory modules were used quite a few years ago and you will only have them in your Pc if it is like a Pentium one or older! (486 or 386 even!)

At the end on their time, SIMMS were 72 pin modules and shorter in length with bigger chips on the board, and DIMMS had 168 pins and longer too.

Please also remember that there are quite a few different types of DIMM memory types out there so to be safe, it would be wise to open the PC and remove one of the modules from your PC and then you will be able to find a match alot easier!

Trust me, you won't break your PC in the process! :)

Good Luck.

Answer 3

SIMM stands for Single Inline Memory Module
DIMM stands for Double (or Dual, cant remember which) Inline Memory Module
unless you have an original Pentium or earlier processor, you have DIMMs
SIMMs had to be installed 2 at a time to work, DIMMs dont have that problem

Answer 4

unless its about 10 years old or older u have dimms ...
