Your Dell OptiPlex uses PC2-6400 type memory.
Your Dell OptiPlex can support up to 8GB of memory. For optimal performance install the maximum amount of memory in each socket.
Your system comes standard with 512MB of RAM. If you have upgraded your system then you may have a different amount.
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.
Your Dell OptiPlex 745 (Minitower, Desktop, SFF) has 2 banks of 2 sockets each for a total of 4 memory sockets.
*We recommend you upgrade your computer to the latest BIOS revision prior to upgrading your memory.
If mixing speeds, the computer will run at the slowest speed detected.
Modules must be purchased and installed in pairs for dual channel performance.
Using more than 4GB of memory requires the use of a 64 bit operating system.
ETC tests each RAM module to ensure compatiblity with your Dell system. The memory modules listed above are guaranteed to work in your Dell OptiPlex 745 (Minitower, Desktop, SFF).

I purchased the ram from edge tech Corp because the price was 1/2 the price of identical ram at other online stores. The service was great. Edgetech site gave me information about the ram and it was easy to determine what to buy. My order came earlier than promised. I will definitely use them again.

As the ad said, the product is fully compatible with the existing memory chip for my Dell computer. I am quite impressed.
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.
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).
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.
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.
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.
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.
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).
