Because of this, your memory may not work correctly in a TYAN board though it may work well in a competitor’s board. This is because many of our competitors do not adhere to the strict tolerances required for high performance. - Page 19 To remove your DIMM, simply pull the clips back, and pull up on the module. Place the DIMMs in an anti-static bag as soon as you remove them to avoid static damage. S2054 Tomcat i810...

Page 21: Installing The Cpu And Cooling Fan
Warning! DO NOT use registered DIMMs. (Check with your memory warning dealer for more information). See www.tyan.com for the latest memory compatibility information. 4. Installing the CPU and Cooling Fan Socket 370 type Celeron processors can be used on the Tomcat i810. Remember: •... - Page 22 Push down lightly on the CPU, and lower the arm on the ZIF socket to secure the CPU. A squeaking noise is normal as the arm lowers. After the CPU is securely seated, install the appropriate cooling device. Tyan strongly recomends a heatsink/fan combination. Consult with your case manufacturer for other cooling options.
