Asus Dual TualatinTM Motherboard TRL-DLS - Manual (Page 18)

18 ASUS TRL-DLS User’s Manual
3. HARDWARE SETUP
Insert a DIMM into the DIMM socket as shown. Because the number of pins are
different on either side of the breaks, the module only fits in one direction. SDRAM
DIMMs have different pin contacts on each side.
The notches on the DIMM shifts between left, center, or right to identify the type
and also to prevent the wrong type from being inserted into the DIMM slot on the
motherboard. You must tell your retailer the correct DIMM type before purchasing.
This motherboard supports four clock signals per DIMM.
Use only 3.3Volt “registered” SDRAM DIMMs. To determine the DIMM type, check
the notches on the DIMMs (see the figure below).
WARNING! Make sure that you unplug the power supply when adding or
removing memory modules or other system components. Failure to do so may
cause severe damage to both the motherboard and expansion cards (see 3.3
Hardware Setup Procedure for more information).
