Asus Terminator Tualatin - Manual (Page 45)

ASUS Terminator Barebone System 45
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.
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 3.4 Hardware Setup Procedure for more information).
Insert the module(s) into the DIMM sockets 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 and have a higher pin density than DRAM SIMMs.
3.6.2 Memory Installation
The DIMMs must be 3.3Volt unbuffered SDRAMs. To determine the
DIMM type, check the notches on the DIMMs (see the figure below).
