2-8.1 Switch S3 For Cpu Clock Select - SOLTEK SL-85DRS User Manual

How to tackle with Jumpers:
• Do not remove the jumper when power is on. Always make sure
the power is off before changing any jumper settings. Otherwise,
mainboard could be damaged.
• In the Jumper setting diagram, all jumper pins covered with black
marks stand for closed pins by jumper caps.

2-8.1 Switch S3 for CPU Clock Select

1. This mainboard is shipped to users with a 5-DIP Switch on board, by
which user can select a CPU clock to match with the Pentium 4
processor installed on board. Yet users are not recommended to
take Switch S3 as a foolproof tool for overclocking. Instead, it is
saver and more advisable to select the CPU clock as near as possible
to the one marked on the selected CPU.
2. An Advice from our Engineering Team:
CPU Overclocking should always take the on-board components into
account. If you are using DDR266 SDRAM on this mainboard, you must
not set the switch S3 to the DDR333 settings; otherwise you risk system
damage.
