Why would I ever want to drop my multiplier?
Although the multiplier allows for the greatest single-step increases in net clock speed, sometimes the increases are too much for the hardware to handle and more precision is required. Suppose for instance we have a FX55 system (configured 1:1) that has a maximum clock of 3.00GHz (i.e., it will not OC any higher)
CPU = 200x13.0 = 2600MHz, RAM = 200MHz (Original)
CPU = 200x15.0 = 3000MHz, RAM = 200MHz (OC via multiplier increase)
CPU = 230x13.0 = 2990MHz, RAM = 230MHz (OC via core clock)
CPU = 250x12.0 = 3000MHz, RAM = 250MHz (OC via multiplier decrease & core increase)
As shown above (assuming the RAM can handle the OC), the last configuration nets the greatest performance from both the processor and the RAM.
