1.2.2.3 Processor and Speed

For National Instruments M- and X-Series boards, WinLTP requires at least a computer with a 2.8 GHz

Intel Pentium 4 or higher speed processor with HyperThreading, the faster the better. (Note: some 2.93

and 3.06 GHz Pentium 4 processors do not have HyperThreading, and will not work with the M- or X-

Series boards.)

For Axon Digidata 132x boards, WinLTP prefers a computer with at least a 3 GHz or higher processor.

However, in contrast to the M- and X-Series boards, the Digidata 132x boards can work with somewhat

slower ca. 2 GHz computers (e.g. processors without HyperThreading), but this speed is really not

recommended.

Both the M- and X-Series boards or the Digidata 132x boards have been tested on the Intel dual-core

processors, and work well, and the M- and X-Series boards have been tested on the newer Intel quad-

core processors, and work well.

The WinLTP Reanalysis program worked fine on all Intel Pentium 4 processors and above and is not

limited to any minimum GHz processor speed.

1.2.2.4 RAM memory

When using either the M- or X-Series or Digidata board, at least 2048 MB of RAM memory is

recommended, although simple LTP experiments can probably be run on computers with a minimum of

1024 MB of RAM memory.

1.2.3 Monitors

Most WinLTP users prefer monitors having 1920x1080 pixels, particularly if many AD channels are used,

if the Protocol Builder is used, and/or if capturing spontaneous events is used. 1280x1024 pixels is now

the minimum screen resolution, and 1024x768 pixels is now too small – not all the perfusion channel

information will be visible.

1.2.4 Operating Systems

For the M- and X-Series boards, WinLTP requires the Windows XP, Vista, 7 or 8 (64- and 32-bit)

operating system (which support HyperThreading and multi-core processors, Windows 2000 does not).

However, Windows Vista has largely been bypassed by most users and institutions, and in our WinLTP

tests, Windows 7 and 8 seem superior to Windows Vista. Windows Vista users should strongly consider

upgrading to Windows 7 or 8.

When running on Windows Vista, 7 or 8, make sure the computer does NOT GO TO SLEEP. This

will cause WinLTP to hang-up! To stop your computer from going to sleep change:

ControlPanel -> SmallIcons -> PowerOptions -> Balanced -> ChangePlanSettings
