J1 Jumpers

(see p.10

No. 28)

Note: The set of J1 jumpers are only for advanced users to adjust the multiplier of CPU. Please

follow the table below to adjust the multiplier of CPU. However, the system will work well

without the adjustment of multiplier. You do not have to adjust the multiplier for normal

usage.

For example, “Athlon XP 2000+” is an 1666MHz CPU:

12.5 (Multiplier) X 133MHz (External frequency) = 1666MHz

FID jumpers setting:

The jumper caps are not provided by ASRock. Please understand that ASRock

does not guarantee and support the adjustment of multiplier. These jumpers

setting may not apply to all multiplier-locked or even some unlocked AMD

CPU. Frequencies other than the recommended CPU bus frequencies may

cause the instability of the system or damage the CPU.
