The 'server' is the computer that runs the MySQL server program and stores the files. It is usually the same computer as the office server but does not have to be. See the section on networks for information on different types of networks.
The speed of the computer, the memory, the video capability, and the
hard drive capacity all affect the performance of the program. An older
computer slower than 700MHz will probably not be able to run Windows.
Also a computer that old will probably be deficient in memory, video,
and hard drive. Memory for older computers is significantly more expensive,
and it is usually more cost effective to buy a new $800 computer than
to put a few hundred dollars into an older computer to upgrade it.
Any midrange computer sold within the last few years will meet the minimum
You should be connected to a highspeed internet connection for the
best access to service and updates. Consider it a requirement.
Flat LCD monitor. All flat LCD monitors support our minimun resolution
of 1024 x 768. We recommend 19" or greater LCD monitors set to a resolution
of 1280x1024 so that you can see more information on the screen.
These are available at online stores such as www.tigerdirect.com for
under $200. Get one with speakers built in.
512 MB memory is the absolute minimum. 2 to 4 GB is best. Open Dental
uses approximately 60 MB of memory. If you run more programs than
you have memory, then your system will run very slow because it
is transferring memory back and forth to the hard drive.

All of your machines do not have to have the same operating system. If you are purchasing new equipment and need a recommendation, we recommend Windows 7 or 8 (64 bit) for all workstations and the
Home editions of windows are sometimes unacceptable because of connection and networking limits, especially with Windows XP. The best editions are Pro, Business, or Ultimate. Any version of Windows 7 will work unless you are using a domain instead of a workgroup (using Windows Server software).
As an alternative to Windows,
the server can run Linux or MacOS-X.

The newer and faster, the better. Recommended
Now that monitors are bigger, a video card can help. Not required,
but recommend NVIDIA. Does not need to be high end.
Open Dental has very minimal hard drive requirements. It
takes up far less than 1 GB, so any hard drive will work.
Open Dental requires both Microsoft dotNet 3.5 and 4.0.
Adobe Reader version 8.0 or later is needed to view PDF files.
Any fairly new notebook, laptop, or Tablet PC that runs a full version of Windows (not Windows 8 RT) will work. They all
support our minimum screen resolution of 1024x768. But because of
the large LCD monitors now available for desktop computers, notebooks
may not be the best choice. If you get a desktop computer
instead of a notebook, you will get a more powerful computer with
a larger screen at a lower price . Also, watch out for mini notebooks with screen resolutions less than 1024x768.
Before using a Tablet PC as a Kiosk device, see Tablet PCs.
