About your Compaq Presario CQ Series


What type of memory do I need?
Your Compaq Presario CQ Series uses PC2-5300, PC2-6400 type memory.

What is the maximum amount of memory that I can add?
Your Compaq Presario CQ Series can support up to 4096MB (4GB) of computer memory. For optimal performance install the maximum amount of memory in each socket.

How much memory does my system have now?
Your system comes standard with 2048MB (2GB) of RAM. If you have upgraded your system then you may have a different amount.

What are banks and sockets?
A bank is a group of memory sockets. A socket is where a memory module is inserted. A bank can have one or more sockets.

One or more of the sockets in your system is already filled with memory. When you upgrade your system, you can either add memory to one of the open sockets and/or remove memory from a filled socket and replace it with a higher capacity memory module.

How many banks and sockets does my Compaq Presario CQ Series have?
Your Compaq Presario CQ Series CQ56-103TU (XV401PA) has 2 banks of 2 sockets each for a total of 2 memory sockets.

Is there anything else I should consider prior to upgrading my Compaq Presario CQ Series memory?
- Although the BIOS will address 4096MB (4GB) of memory, the amount available to the system will be less than 4096MB (4GB) depending on computer resources.
- Modules must be purchased and installed in pairs for dual channel performance.
- System is capable of recognizing 4GB of memory. However, due to the 32-bit limitation of MS Windows/Mac OS, Operating System can only utilize 3.25GB of the memory when 2GB + 2GB are installed. Therefore we recommend the configuration of 2GB + 1GB = 3GB for this system. 64-bit windows would not have this limitation.

FAQ

General questions about upgrading memory


What is memory?
Memory or RAM is a piece of hardware in your Compaq Presario CQ Series CQ56-103TU (XV401PA) that holds software applications that you are working on. It serves as temporary working space between your computer's hard drive and CPU.

Why add memory to my computer?
Adding memory will improve your Compaq Presario CQ Series CQ56-103TU (XV401PA)'s performance. Specifically, it will speed up opening new applications, running multiple applications at once, and switching between software applications (multi-tasking).

How does additional memory improve performance?
One task that additional memory speeds up is opening a new software application. Let's take this as an example. When you open a new application on your Compaq Presario CQ Series CQ56-103TU (XV401PA), your computer's CPU fetches the application from the hard drive and stores it in RAM memory. It stores it in RAM because RAM is very fast relative to the hard drive. When RAM gets full, and you open a new application then the CPU needs to kick out one of your open applications, put it back on the slow hard drive, fetch the new application from the hard drive, and place the new application in RAM. Basically, it swaps the applications.
This game of swapping wastes time. Ideally, your computer could have an infinite amount of RAM. Then your CPU would fetch an application once from the hard drive, save it into RAM, and never need to kick out another application. There is no such thing as infinite RAM, but you can max out the RAM on your computer by adding the maximum amount of memory to each socket.

How do I max out the memory on my system?
The maximum RAM your Compaq Presario CQ Series CQ56-103TU (XV401PA) can support is 4096MB (4GB), and your system has 2 sockets.
To max out your RAM memory, add the maximum amount of memory to each memory socket.To find out how much RAM each socket can support, divide the system maximum RAM amount by the total number of sockets in your system. For example, if your system maximum RAM is 2GB, and your system has 2 total sockets then the maximum amount each socket can support is 1GB. If one of the sockets is already filled then you can always remove the existing module and replace it with a higher capacity module.

Will adding memory void my warranty?
No. The 1975 Magnusson-Moss Act prevents OEM manufacturers from disqualifying a warranty when 3rd party memory is used. For more details, please see the Magnuson-Moss Act.

What is memory speed?
Memory speed refers to the amount of time that memory (RAM) takes to put data into its memory or send it out. Your device's memory will have an upper limit on the speed at which it can operate.

What is a memory kit?
A memory kit is a number of memory modules sold as a unit or a kit. For example, a 1GB memory kit will contain two 512MB modules. This is written as (2x512MB).

What is the difference between RAM & Hard Drive Memory?
RAM and hard drive disk space are both referred to as memory which can be confusing. RAM is a series of memory sticks in your computer that temporarily holds software applications and documents that you are working on, prior to saving it. Once saved, the documents or software applications are saved permanently on your hard drive. If you are running low on disk space on your hard drive you can consider purchasing a portable hard drive or flash drives to store your files on.
