    Standard Configuration for Compaq ProLiant BL20p G4

    • What type of memory do I need?

      Your Compaq ProLiant uses PC2-5300 type memory.

    • What is the maximum amount of memory that I can add?

      Your Compaq ProLiant can support up to 32GB of 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 2GB of RAM. If you have upgraded your system then you may have a different amount.

    • What is a memory kit?

      A memory kit is comprised of 2 memory modules. For example, a 1GB memory kit has two 512MB memory modules. This is abbreviated as (2x512MB).

    • Does my system require a kit?

      Yes. Your Compaq ProLiant requires memory to be installed as a kit because it requires memory to be installed in pairs within a bank. To make it easier for you to install memory that will be compatible, the memory modules available for purchase above are sold in kits.

    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 have?

    Your Compaq ProLiant BL20p G4 has 4 banks of 2 sockets each for a total of 8 memory sockets.

    Setup 1

    Bank 1

    Sockets 1 - 2

    Bank 2

    Sockets 3 - 4

    Bank 3

    Sockets 5 - 6

    Bank 4

    Sockets 7 - 8

    Is there anything else I should consider prior to upgrading my Compaq ProLiant memory?

    *We recommend you upgrade your computer to the latest BIOS revision prior to upgrading your memory.

    32GB max when 4GB modules are available.

    Memory DIMMs in systems with the Front Side Bus (FSB) running at 1333 MHz will run at 667 MHz and in systems with a FSB running at 1066 MHz or 667 MHz the memory DIMMs will run at 533 MHz.

    When DIMMs 1A and 3A are populated the system is automatically configured for 2:1 interleaving. When four or six DIMMs are populated with identical DIMMs the system is automatically configured for bank interleaving.

    When upgrading memory, DIMMs 1A and 3A must match. DIMMs 5B and 7B, DIMMs 2C and 4C and DIMMs 6D and 8 D must match and must be installed as a pair.

    How do I know that ETC memory will work with my system?

    ETC tests each RAM module to ensure compatiblity with your Compaq system. The memory modules listed above are guaranteed to work in your Compaq ProLiant BL20p G4.

    Jon recommends this product.

    I ordered a memory upgrade for two of our HP Proliant ML350 G5 servers. The price from Edge.com was far superior to that of my regular vendors. I was about to place the order but I wanted to verify part numbers first. I have used Edge.com in the past, so I knew the quickest way to find exactly what I wanted would be at Edge.com. I had my part numbers in seconds, but I also saw some fantastic pricing on the products I needed. Plus, I did not pay shipping and the delivery came in a matter of days. It was a great experience and I'll surely be back for my memory needs in the future! Thanks Edge.

  • Memory FAQs

    General questions about upgrading memory

    • What is memory?

      Memory or RAM is a piece of hardware in your computer 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 computer’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 computer, 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?

      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).
