CPU Core Clock
This section discusses how to effectively increase the CPU core clock of the AMD
Athlon FX-62 CPU on NVIDIA nForce 590 SLI chipset. Before you proceed to
overclock the CPU core clock, eliminate all other sources of system instability. Do
so by keeping memory and CPU HyperTransport frequencies low.
Use the following procedure to overclock the FX-62 CPU:
1. Go to the
