This guide will provide a basic overview of the Overclocking section in the UEFI/BIOS on the NZXT N7 B650E Motherboard. Please note, this guide will not go into detail for every feature in the Overclocking section, instead providing a basic overview of the features provided on the motherboard.

Disclaimer
AMD processors, including chipsets, CPUs, APUs, and GPUs (collectively and individually "AMD processor" are intended to be operated only within their associated specifications and factory settings. Operating your AMD processor outside of official AMD specifications or outside of factory settings, including but not limited to the conducting over overclocking (including with the provided tools in the UEFI/BIOS or through overclocking software, even if such software has been directly or indirectly provided by AMD or an entity otherwise affiliated in any way with AMD), may damage your processor, affect the operation of your processor or the security features therein and/or lead to other problems, including but not limited to damage to your system components (including your motherboard and components thereon (i.e. memory)), system instabilities (i.e. loss of data and corrupted files), reduction in system performance, shortened processor, system component and/or system life, and in extreme cases, total system failure.
It is recommended that you save any important data on your PC before undertaking any overclocking efforts. NZXT does not provide support or service for issues or damages related to the use of an AMD processor outside of official AMD specifications or outside of factory settings.
Damages caused by use of your AMD processor or the NZXT B650E motherboard outside of official AMD specifications or outside of the factory settings for the NZXT B650E motherboard are not covered under any AMD or NZXT product warranty and may not be covered by other manufacturer warranties (i.e. RAM and GPU).
Overclocking Tab
CPU Overclocking - This setting will include overclocking presets based on factors provided by AMD. (default: Auto)
DRAM Frequency - If [Auto] is selected, the motherboard will detect the memory module(s) inserted in the motherboard and assign an appropriate frequency based on the memory's own onboard profiling (default: Auto)
DRAM Profile Configuration - This section will allow you to load EXPO/XMP settings from the memory's onboard profiles, as well as allow you to overclock the memory beyond its specifications.
- DRAM Profile Setting - This setting will include not only Automatic profile selection, but allow you to select from any onboard profiles such as AMD EXPO as well as XMP or DOCP settings. (default: Auto)
- DRAM Performance Mode - This setting will include modifiers for the above DRAM Profile Setting option. Please note that enabling these settings may increase the power limit for the RAM and can result in reduced memory lifespan. Competitive will provide a minor overclock while Aggressive will provide a higher overclock by comparison. (default: Auto)
DRAM Timing Configuration - This section will allow you to manually adjust the timings for the RAM installed in your PC. This includes, but is not limited to CAS Latency (tCL), RAS# to CAS# Delay to Read (tRCDRD), and various other settings.
- DRAM Bus Control Configuration - This section will include advanced settings for power management for your DRAM, including the ability to enable or disable DDR5 Power Down Mode (default: Disabled) and adjust various settings such as Processor ODT Impedance and DRAM ODT Impedance.
DRAM Voltage Control - This setting allows you to set the power mode for the memory installed. High Voltage Mode option is only available when supported DIMMs are installed. When using High Voltage Mode, the upper range for VDD and VDDQ will be increased to 2.070V. (default dependent on DRAM Profile loaded).
- VDDIO Voltage (VDDIO_MEM_S3) - This setting allows you to set the voltage used for memory signaling, also known as the "Memory Voltage" or "DRAM Voltage" (default dependent on DRAM Profile loaded).
- DRAM VDD Voltage - This is the main setting for the voltage going to the DRAM. This voltage is crucial to the memory's operation (default dependent on DRAM Profile loaded). For most overclocks, it is not recommended to go over 1.4V.
- DRAM VDDQ Voltage - This setting controls the voltage fed to the memory chip's I/O and is generally tried to the VDD Voltage (default dependent on DRAM Profile loaded).
- DRAM VPP Voltage - This setting controls the peak-to-peak voltage on the memory (default dependent on DRAM Profile loaded).
Infinity Fabric Frequency - A setting specific to AMD Overclocking, This allows you to set the Infinity Fabric frequency (FCLK) for your system. This value must be less than your Memory Clock (MCLK) for best performance in most cases.
UCLK DIV1 MODE - A setting specific to AMD Overclocking, this enables the system to force the memory controller to run at the same or half the system's memory frequency.
SoC/Uncore OC Voltage (VDD_SOC) - Specifiies the SoC/uncore voltage (VDD SOC) to support memory and Infinity Fabric overclocking. VDD_SOC also determines the GPU voltage for processors with integrated graphics.
VDD Misc, VDDG CCD, and VDDG IOD Voltage - VDDG is the supply of power for the fabric data path and is derived from VDDCR_MISC (VDD Misc). When memory overclocking, increasing the VDDG may be necessary.
External Voltage Settings - This submenu includes a number of settings for the input voltage for the processor.
- VDDCR_CPU Voltage
- VDDCR_CPU Load-Line Calibration
- VDDCR_SOC Voltage
- VDDCR_SOC Load-Line Calibration
- VDD_MISC Voltage
- PCH 1.05V Voltage
- VDD_MISC_S5 Voltage
- 1.8VSB Voltage
Overclock Mode (Bus Speed) - This setting allows the user to change the Overclock mode for the PC. A a warning: When overclocking the PCIe bus, this will also overclock the PCI, SATA, and USB controllers which can cause major instability or failure. Please be sure to install and update your operating system and all necessary drivers before overclocking (default: Auto).
Lastly, we'll have a few options to save and load your Overclocking Profiles. Before starting an Overclock, it is recommended to save the User Default settings to a flash drive in case a reset is necessary.
