18 ASUS P2Z User’s Manual
2. 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) of either 8, 16, 32, 64, 128MB, or 256MB.
The Intel 440ZX AGPset does not support ECC function. However, ECC memory
modules may be still used, but the ECC function will not be available.
Memory speed setup is recommended through SDRAM Configuration under “Chipset
Features Setup” in BIOS SETUP.
III. HARDWARE SETUP
NOTE: At the time this User’s Manual was written, 256MB DIMMs are only avail-
able as registered memory.
Serial Presence Detect (SPD) Support
This motherboard supports SPD DIMMs, and it is recommended that SPD DIMMs
be used.
General DIMM Notes
•
For the system CPU bus to operate above 100MHz, use only PC100-compli-
ant 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 bus frequency to 66MHz for system stability.
• SDRAM chips are generally thinner with higher pin density than EDO (Ex-
tended Data Output) chips.
• BIOS shows SDRAM memory on bootup screen.
• Single-sided DIMMs come in 16, 32, 64,128MB; double-sided come in 32, 64,
128, 256MB.
Install memory in any combination as follows:
DIMM Location 168-pin DIMM Total Memory
Socket 1 (Rows 0&1) SDRAM 8, 16, 32, 64, 128MB x1
Socket 2 (Rows 2&3) SDRAM 8, 16, 32, 64, 128MB x1
Total System Memory (Max 256MB) =
