Jumper 6A/B/C/D
-
this jumper enables the DDR terminator for DDR memory.
If you installed DDR memory in DDR1/DDR2, short all the jumpers. Otherwise,
if you installed SDR memory in DIMM1/DIMM2, open all the jumpers.
Jumper 7
– this jumper enables to select voltage of DRAM.
Jumper 8
– the CPU voltage is defined according to the VID table. VID4 is
derived from the CPU only and cannot be changed. While VID0 ~ VID3 can be
changed manually by setting the jumper 8 to adjust the CPU voltage. However,
this is not recommended. If you overclock, you might need to increase the
CPU voltage.
a.
Auto:
Set the CPU voltage according to its default setting. Short
pin numbers 1-2, 4-5, 7-8, 10-11.
b.
Manual:
Set the CPU voltage manually. Open all pins of jumper 8
and set the pins as follow:
Where VID0 ~ VID3 are pin numbers
2-3
,
5-6
,
8-9
,
11-12
respectively of jumper 8. Thus, VID0 ~ VID3 will be equal to “
0
”
by shorting pin numbers 2-3, 5-6, 8-9, 11-12 or “
1
” by opening pin
numbers 2-3, 5-6, 8-9, 11-12.
VID4 depends on the CPU
. See table below.
