System Memory (Dimm); General Dimm Notes - Asus MES-N User Manual

3. HARDWARE SETUP

3.5 System Memory (DIMM)

NOTE: No hardware or BIOS setup is required after adding or removing memory.
This motherboard uses only Dual Inline Memory Modules (DIMMs). Sockets are
available for 3.3Volt (power level) unbuffered Synchronous Dynamic Random Ac-
cess Memory (SDRAM).
The SiS chipset does not support ECC. However, ECC memory modules may still
be used, but the ECC function will not be available.
Memory speed setup is recommended through SDRAM Configuration in 4.4.1
Chip Configuration.
Install memory in any combination as follows:
DIMM Location
Socket 1 (Rows 0&1)
Socket 2 (Rows 2&3)

3.5.1 General DIMM Notes

• VGA shared memory with one DIMM: When using only one DIMM as shared
memory for the onboard VGA, it must be inserted into Socket 1, leaving Socket
2 empty.
• At the time this User's Manual was written, 256MB DIMMs are either available
as registered memory or 128Mbit DIMMs.
• For the system CPU bus to operate at 100MHz, use only PC100-compliant
DIMMs. When this motherboard operates at 100MHz, most system will not
even boot if non-compliant modules are used because of the strict timing issues
involved under this speed. If your DIMMs are not PC100-compliant, set the
CPU external frequency to 66MHz RAM to ensure system stability. NOTE: If
your motherboard supports asynchronous mode, set the memory clock frequency
to 66MHz.
• ASUS motherboards support SPD (Serial Presence Detect) DIMMs. This is the
memory of choice for best performance vs. stability.
• SDRAM chips are generally thinner with higher pin density than EDO (Ex-
tended Data Output) chips.
• BIOS shows SDRAM memory on bootup screen.
