ASUS P2Z-B User’s Manual
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.
•
Two possible memory chips are supported: SDRAM with and without ECC.
•
SDRAM chips are generally thinner with higher pin density than EDO (Ex-
tended Data Output) chips.
•
BIOS shows SDRAM memory on bootup screen.
•
8 chips/side modules do not support ECC, only 9 chips/side modules support ECC.
•
Single-sided DIMMs come in 16, 32, 64,128MB; double-sided come in 32, 64,
128, 256MB.
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, 128, or 256MB.
The Intel 440ZX AGPset does not support ECC function. ECC memory modules
may be used but the ECC function will not be available.
Memory speed setup is recommended through
SDRAM Configuration
under “Chipset
Features Setup” in BIOS SETUP.
Install memory in the following combinations:
Location
168-pin DIMM SDRAM
Total Memory
DIMM1
Single-sided
x1
(Rows 0&1)
Double-sided
DIMM2
Single-sided
x1
(Rows 2&3)
Double-sided (Socket 3 must be empty)
DIMM3
Single-sided (Socket 2 must be single-sided)

(Row 3)
(Double-sided cannot be used here!)
Total System Memory (Max 512MB)
=
IMPORTANT!
A total of four rows of memory is supported on this motherboard.
One side (with memory chips) of the DIMM takes up one row. Because Socket 3
shares Row 3 with Socket 2, Socket 3 can only be used if Socket 2 does not use
Row 3.
WARNING!
If Row 3 is used by both Socket 2 and 3, your system will not boot up!
