5 Easy Steps to Add Laptop Memory

Executive Summary about  Laptop Memory by Dan L Morris

Laptop Computer Memory

I am going to show you 5 simple steps on how you can add laptop memory. Before you ever add laptop memory to your machine, you have to find memory that will work on you system. One option is to purchase the memory on ebay. Simply unscrew that panel and you should see the memory.

Step 1) Get the tools
A. Philips Head Screwdriver - yes, that really is all you nee

Step 2) Turn off your computer
A. Turn off your computer
B. unplug
C. remove battery

Step 3) Open up your computer
On the bottom of you laptop you should see a small panel with screws it it. You might see a couple of different panels.

Step 4) Put new memory in
Most laptop’s have two slots where you can add laptop memory. Just put the memory in the slot. If all memory slots are in use, you can remove some of the old memory.

Step 5) Put everything back the way it is supposed to go.
A. Screw the panel back onto your computer
B. Reattach the battery and plug it back in
C. turn you computer on.

Notebook-Laptop Memory (RAM) Upgrade In 5 Minutes Or Less

Executive Summary about  Laptop Memory by Christophe Catesson

1 - RAM Overview

There are two big categories of random access memories:

* Dynamic memories (DRAM, Dynamic Random Access Module), not very costly. * Static memories (SRAM, Static Random Access Module), quick and expensive. Functioning of the random access memory

The random access memory is constituted of hundred of thousand small condensers storing charges. Memory DRAM requires cycles of refreshment for instance (Ns) is about 15 nanoseconds.

As a result a computer having a frequency well brought up and using memories the time of access of which is much longer than the time of cycle of the processor must perform cycles of wait to access to the memory. Formats of Random Access Memory (RAM)

There are numerous types of random access memories.

* SIMM (Single Inline Memory Module): it is about printed circuits among which one of the faces has fleas of memory.

* DIMM (Dual Inline Memory Modulates) are from memories 64 bits, what explains why it is not necessary to match them.

* RIMM (Rambus Inline Memory Module, conscripts also RD-RAM or DRD-RAM) are from memories 64 bits developed by the society Rambus. 1 byte consisting of 8 bits, a barrette of memory 256 Mb DRAM will contain 256 therefore * 2^10 * 2^10 = 256 * on 1024 * on 1024 = 268 435 456 bytes = 268 435 456 * 8 = 2 147 483 648 bits = 2 147 483 648 transistors. The time of access to memory EDO is therefore about 50 - 60 nanoseconds for a frequency of functioning going 33 - 66 Mhz.

* DDR-SDRAM (Double Dated Miss SDRAM) is a memory based on technology SDRAM, allowing to double the rate of transfer of SDRAM with equal frequency. Reading or writing of data in memory am accomplished on the basis of a clock. Standard memory DRAM uses a method conscript SDR (Single Data Fails) consisting in reading or writing data in every forehead going up.

2 - Upgrading Your Laptop RAM

To take out existing memory, simply flip the clips and then remove the memory strips gently from their holding place.
