Double Vs Single Sided Ram

I’ve seen many poorly answered questions about single and double sided ram and frankly it’s amazing that so many people are getting this wrong. Especialy with the internet rescources at your fingertips. So listen up once and for all: The dif between single and double sided ram is this; Double sided ram has two groups of chips. (These two groups can be laid out on the stick in any configuration the manufacturer wants. Generally one group is located on each physical surface of the stick, but not always.)However, that is not why it is called double sided. This is; the computers memory controller sees each of those two groups of chips seperately and can only read/write to one of them at a time. In order to read/write to the other one the controller must switch back and forth between chip groups. NOW,…To settle the argument; Single sided ram has only one group of chips that the controller sees all at the same time. These chips may be laid out on one or both sides of the stick, it doesn’t matter. All single sided means is that the chips are a single group that are used simultaniously, (now here it is) therefore making it MUCH faster than double sided ram.
Now for the fun part; finding single sided ram can be tricky. Sometimes ram that is denoted as “High performance or for extreme gaming” will get you some single sided ram. Otherwise, you might try this; Pins 33 and 45 on the board are used by double-sided memory, and can sometimes be an indicator as to whether a given module is single or double-sided. Happy Hunting!
