Board Installation
2. Mounting the Motherboard in the Chassis
Follow the instructions provided by the case manufacturer for proper installation
guidelines. TYAN recommends that you make use of all mounting holes to screw down the
motherboard. The adapter cards and the screws holding them down will keep your board
flat. The fastening screw should not short any of the traces on the motherboard. Make
certain that you do not overtighten the screw, as it will damage the motherboard and
possibly break internal traces in the surrounding area. The hole you should use is located at
the top-center of the board where the adapter cards are fastened to the case.
3. Installing Memory
Since TYAN boards are manufactured with performance in mind, you should use add-in
components that match. Some DIMM modules may seem to be high quality because of
name or feel but that does not guarantee real-world usability. Some cheaper or OEM
memory may have brand-name components, but they may contain inferior or substandard
parts which do not meet the critical tolerances our products require. Because of this, your
memory may not work correctly in a TYAN board though it may work well in a
competitors board. This is because many of our competitors do not adhere to the strict
tolerances required for high performance. If you buy a TYAN board, you are getting the
best system available. To make installation easy and trouble free, get high quality parts.
For a list of recommended memory vendors, please visit Tyans website at www.tyan.com -
go to the Memory Support area in the Support Section. The website memory compat-
ibility lists include DIMMs that have proven to be very stable on our boards and perform
extremely well.
