CoreModule 800 QuickStart Guide 13
Chapter 2 Installing CoreModule 800 Options
The procedures in the first part of this chapter describe how to install or remove the CoreModule 800
SBC (Single Board Computer) options onto or from the board, including the SODIMM card. Brief
instructions for loading supported Operating Systems and accessing the CoreModule 800 Doc & SW
(Documentation and Software) CD-ROM are also provided at the end of this chapter.
Memory Installation
The CoreModule 800 uses a single SODIMM socket available on the underside of the board. The
CoreModule 800 supports PC 2700 DDR 333 (333 Mbps, 166 MHz) or PC 2100 DDR 266 (266
Mbps, 133 MHz), +2.5V, 200-pin, DDR RAM SODIMM.
NOTE Ampro recommends using PC 2700 DDR 333 (333 Mbps, 166 MHz,
6 ns), +2.5V, 200-pin, DDR RAM SODIMM for maximum performance.
The CoreModule will operate acceptably with a PC 2100 DDR 266
(266 Mbps, 133 MHz, 7.5 ns) SODIMM.
Tools Required
Use an anti-static service kit (or the equivalent) to remove or install the SODIMM. An anti-static service
kit should include a static-dissipating work surface, a chassis clip lead, and a wrist or ankle strap.
Installation Guidelines
• When handling a SODIMM, observe anti-static discharge precautions to avoid damage.
• The CoreModule 800 uses PC 2700 DDR 333 (166 MHz) or PC 2100 DDR 266 (133 MHz),
RAM SODIMMs, which are electrically different from SDR (Single Stroke) SODIMMs.
• The following DDR SODIMMs sizes are available from Ampro: 128 MB, 256 MB, 512 MB,
or 1 GB.
• The CoreModule 800 supports up to 1 GB of memory in the SODIMM socket.
Removing the SODIMM
Use this procedure to remove the SODIMM from the SODIMM socket on the CoreModule 800.
1. Prepare the CoreModule 800 for SODIMM removal:
♦ If the CoreModule 800 is already prepared for SODIMM removal, with the power turned off,
and the power cord disconnected, skip to Step 4.
♦ If the CoreModule 800 is operating, power down the system and continue with next step.
CAUTION To prevent damage to the CoreModule 800 and the SODIMM, ensure the
power switch on the AT or ATX power supply is turned off and the power
cord has been removed from the AC power source. The typical ATX
power supply will continue to provide standby current to the board until
the power cord is disconnected.
2. Disconnect the ATX or AT power supply’s power cord from the AC power source.
