Chapter 3 Award BIOS Setup
6253M Mainboard
dynamic random access memory (DRAM). The default timings have been carefully
chosen and should only be altered if data is being lost. Such a scenario might well
occur if your system had mixed speed DRAM chips installed so that greater delays
may be required to preserve the integrity of the data held in the slower memory chips.
EDO
DRAM Speed Selection
The DRAM speed is controlled by the DRAM
timing Registers. The timings programmed into this register are dependent on the
system design. Slower rates may be required in certain system designs to support
loose layouts or slower memory. i.e. 50ns; 60ns
EDO CASx# MA Wait State
This item allows you to select EDO CASx# MA Wait
State. The choice : 1, 2
EDO RASx# Wait State
This sets the relative delay between the row and column
address strobes from DRAM (EDO). The choice : 1, 2
Auto Detect DIMM/PCI ClK
If this item is enabled, the unused DIMM and PCI slot
clock will be disabled. If this item is disabled the unused DIMM and PCI slot will still
get the active clock signal.
Clock
/ Spectrum Control
When Disabled/Off (or Disabled/On), the system will
automatically set the base frequency according to the CPU type :
Pentium
II 233~333MHz & Celeron
TM
266~466MHz: Set to 66MHz.
Pentium
II 350~450MHz and Pentium
III: Set to 100MHz.
When “Enabled/”, there is another item shown as:
“CPU Clock/Spread Spectrum”
for user to set the base frequency and enable/disable the clock generator spread
spectrum manually.
CPU Clock
/ Spread
Spectrum
Use this item to set CPU base clock frequency and
Enable / Disable the clock generator spread spectrum which includes 66MHz/Off,
66MHz/On, 75MHz/On, 78MHz/Off, 81MHz/Off, 83MHz/On, 90MHz/On, 95MHz/
On, 100MHz/Off, 100MHz/On, 105MHz/On, 110MHz/On, 112MHz/On,
113MHz/Off, 115MHz/On, 117MHz/Off, 118MHz/Off, 120MHz/On, 122MHz/Off,
124MHz/On, 126MHz/Off, 133MHz/Off, 133MHz/On, 135MHz/Off, 137MHz/Off,
138MHz/Off, 140MHz/On, 142MHz/Off, 144MHz/Off, 150MHz/On and
155MHz/Off.
Note:
After you change the CPU Clock Frequency and the system can not start,
please do the following procedures:
1. Turn the system off first.
2. Turn on the system. Then press and hold the “ Insert ” key at boot.
3. Select the proper frequency in the item of
CPU Host/PCI Clock
.
4. Save and Exit Setup.
