3.4. DRAM INSTALLATION
The mainboard can be installed with 8/16 / 32 / 64 / 128 / 256 MB 168 pins
DIMM module DRAM, and the DRAM speed must be 67~100 MHz for
SDRAM. The DRAM memory system on mainboard consists of bank 1,2&
bank3.
Because the 168 pins DIMM module is 64 bits width, using 1 PCS which can
match a 64 bits system. The total memory size is 8 MB ~ 256 MB DRAM.
The DRAM installation position refer to Figure 3.1, and notice the Pin 1 of
DIMM module must match with the Pin 1 of DIMM socket. Insert the DRAM
DIMM module into the DIMM socket at Vertical angle. If there is a wrong
direction of Pin 1, the DRAM DIMM module couldn't be inserted into socket
.

3.5. SRAM INSTALLATION
Sync. SRAM (Pipeline Burst SRAM)
If Sync SRAM Chip is installed, it consists of Pipeline Burst 1 Pc 64 K x 64
512KByte.
There is no jumper for cache size setting.
3.6. CPU INSTALLATION AND JUMPERS SETUP
The system speed depends on the frequency of CLOCK GENERATOR. The
user can change SW2 selection to set up the system speed to 60 or 66 or 75
or 83 or 95 or 100 MHz for 3.3V/2.5V Pentium
Processor (90-233 MHz) /
AMDK5(PR133/PR166)AMDK6(166/180/200(2.9V)/233(3.2V)/266/300(2.2V))
/AMD-K6-2 (250/266/300/333/350)(2.2V),Cyrix / IBM 6x86 (PR150+ /
PR166+/ PR200+), Cyrix / IBM 6x86L (PR150+/PR166+/PR200+ (2.8V)),
Cyrix / IBM 6x86MX (PR166 (60x2.5 2.9V) / PR200 (66x2.5 2.9V) (75x2
2.9V)/ PR233 (66x3 2.9V) (75x2.5 2.9V) / PR266 (66x3.5 2.9V) (75x3
2.9V) (83x2.5 2.9V)) IBM MX PR333 (100*2.5 2.9V).
The mainboard can use Pentium
Processor, P54CT, MMX or P54CTB,
AMDK5, AMD-K6, AMD-K6-2, Cyrix / IBM 6x86, CPU, and the CPU speed
must match with the frequency of CLOCK GEN. It will cause system hanging
up if the CLOCK GEN.'S frequency is faster than CPU's.
