Double And Single Sided Ram

[mrlayance]

What is the difference between double and single sided SDram?

One has ram chips on both sides the other doesn't. Don't know what else is different

lol nice explanation

Also, Generally most motherboards that have 3 SDRAM/DDR RAM Slots support 6 banks.....if you shove in 3x double sided you use all 6 banks....if you shove in 3x single sided you only use 3 banks.

Take a 128mb PC133 stick with 8 memory chips....in single sided form each chip would contain 16mb RAM.....in double sided with 16 memory chips each chip would contain 8mb RAM.

It is supposed that single sided ram also overclocks beter.. don't remeber where i read that unfortunately

for modern sdram, if both ram are 256MB,
double side means each side has 8 128Mbit chips, total 16 128Mbit chips.
single side means only side has 8 256Mbit chips, total 8 256Mbit chips.
256Mbit chip is newer than 128Mbit chip, and of course double the density/size (here size means the amount of memory, not the physcial size)

with double sided dimms you can have bank interleave. it is not a great boost in performance but is a boost none the less. on my mainboard i can have 2-way or 4-way bank interleave depending on how many modules i have installed.

-hope this helps

This is very wrong!!!
A single 64Mbit ram chip already can do 4-bank interleave.
You don't need 2 double side ram to get 4-bank interleave.
1 single side ram using 64Mbit or above chips already can do 4-bank interleave.
You're confused by the motherboard's banks to this bank.
