HyperTransport™ Reference Clock (HT ref. clk) : The base clock for various clock domains on the AMD “Scorpius” platform technology. HT ref. clock is 200MHz by default. CPU, CPU NB, HT Link and Memory clocks are all linked to HT ref. clock. HT ref. clock adjustment is a good tool for fine tuning the various clocks to optimal values. The HT ref. clock value itself doesn’t have any impact on performance.

CPU: Central Processing Unit – the engine of the AMD “Scorpius” platform technology. CPU core clock frequency has the biggest impact on overall performance of the system. It’s the primary target of tuning.

CPU NB: CPU NorthBridge (should not be confused with NorthBridge chipset, such as the AMD 990FX chipset)

–part of the CPU that has its own clock domain and voltage plane. CPU NB clock frequency determines the Memory controller and L3 cache speed. CPU NB has a notable impact on overall system performance.

CPU FID: CPU Core Clock multiplier. In the case of the FX-8150 CPU, the default, base-level CPU multiplier is x18 (18x200MHz = 3600MHz). CPU Multiplier can be adjusted on the fly with AMD OverDrive™ utility in st eps of 0.5x. CPU Multiplier is unlocked on all of the AMD FX-series CPUs.

CPU NB FID: CPU NB Clock Multiplier. Determines the CPU NB frequency. In the case of the AMD FX-8150 CPU, the default value is x11 (11x200MHz = 2200MHz). CPU NB Multiplier adjustment requires a reboot (it can not be adjusted on the fly). Can be adjusted in steps of x1. Note that CPU NB clock should be 2x Memory clock or higher (e.g. DDR3-2400 (1200MHz) would require at least 2400MHz CPU NB clock). CPU NB Multiplier is unlocked on all of the AMD FX-series CPUs.

HT Link Multiplier: This multiplier determines the clock speed of the HT Link. In the case of the AMD FX-8150 CPU, the default value is x13 (13x200MHz = 2600MHz). In most cases a reboot is required for HT Link Multiplier value adjustment. The maximum value of HT Link Multiplier is x13. HT Link Multiplier is unlocked on all of the AMD FX-series CPUs.

CPU VID: CPU Voltage Identification Digital – a register value that programs the motherboard voltage regulator (VR) to a specific value. In short, the CPU VID determines the CPU Core Voltage level. In the case of the AMD FX-8150BE CPU, the default CPU base clock VID is usually from 1.250V to 1.350V. The Maximum CPU VID value is 1.550V. NOTE: VID value may not always equal to the actual voltage level (see “Voltage OFFSET”). VID value can be adjusted on the fly with AMD OverDrive utility.

CPU NB VID: CPU Voltage Identification Digital – a register value that programs the motherboard voltage regulator (VR) to a specific value. In short, the CPU NB VID determines the CPU NB Core Voltage level. In the case of the AMD FX-8150BE CPU the default CPU NB VID is usually 1.100V. The Maximum CPU NB VID value is 1.550V. NOTE: VID value may not always equal to the actual voltage level (see “Voltage OFFSET”). VID value can be adjusted on the fly with the AMD OverDrive™ utility.
