Your OptiPlex 745 Series (Desktop Mini-Tower and Small Form Factor) System Specs

System specs as shipped by the manufacturer.
Scan your system to view your specific system configuration.

Memory:

DDR2 PC2-6400, DDR2 PC2-8500, DDR2 PC2-5300

Memory Type: DDR2 PC2-6400, DDR2 PC2-8500, DDR2 PC2-5300, DDR2 (non-ECC)
Maximum Memory: 8GB

Although the memory can be installed one module at a time, the best performance comes from using matched pairs of modules.

How much memory your Windows OS will recognize depends on which version of Windows you are running. 32-bit versions of Windows will see (and utilize) only 3GB or 3.5GB. To utilize more memory, install a 64-bit version of your OS. More information about OS memory maximums can be found here.

Memory or DRAM is the "working" memory of the computer. It's used to store data for programs (sequences of instructions) on a temporary basis.

Storage:

SATA

Storage Drives -- hard drives and solid state drives -- are the permanent memory for the programs and documents on your computer.

Data Transfer Rate is the rate at which data can be sent or received. This is determined by your motherboard. A drive with a higher transfer rate will only run at the rate of the motherboard's transfer rate.

Cache is a type of working memory that allows the drive to perform faster.

RPM is the rotations per minute of a hard drive which effects the speed of data transfer.

Solid State Drives are non-moving memory, so access speed is instant.

Graphics Card:

PCI Express x16 Graphics

External Connector: 15-hole connector

Graphics Card A circuit board fitted to a computer containing the necessary video memory and other electronics to provide a bitmap display. Adaptors vary in the resolution (number of pixels) and number of colours they can display, and in the refresh rate they support. These parameters are also limited by the monitor to which the adaptor is connected.

    I use this on a business computer / medium gaming computer.

    The added ram allows me to let my computer run smoothly, especially in graphic heavy applications, as well as video / media scenarios.

    I trust Crucial. That is why I ordered from them. Their System Checking software was perfect and gave me better confidence in my purchase.

          This memory was to increase the performance over stock issue and postpone the need to purchase a new computer for a few years. I believe it worked. B-)

                  I buy a lot of hardware products in my job, including RAM upgrades. Crucial has always been tops in multiple areas in my book: accurate and easy web configurator, excellent quality, very competitive pricing [...]. Thanks for an excellent product backed by equally excellent customer service. Please hang on through these difficult economic times!
