Are you eagerly awaiting the new AMD X870(E) motherboards? They don’t necessarily have to be “better” than the Gigabyte B650E Aorus Pro X USB4 in any fundamental way. The features of this motherboard match what can be expected in models with “800 series” chipsets. These will be coming out soon, but USB4 support, which is a key new feature, is already available on the Gigabyte motherboard. So there might not be too many practical differences.
What it looks like in the BIOS
Easy Mode is made up of logically well-divided segments, where there is something different in each one. Partly informational only, partly configurable. From this screen you can find out which processor you have in your board, what memory, SSDs and how these components are configured, or what their current operating clock speeds, voltages or temperatures are. Information about the BIOS or microcode version is also available. The microcode in our case is AGESA 1.2.0.0.0a patch A (i.e. the microcode already well optimized for Ryzen 9000).
Among the buttons, there is also a switch for quick selection of the ReSizable BAR (enabled in the factory settings) and you can also activate the memory profile (EXPO) here, for example.
For AMD EXPO settings, you can also go to the advanced settings, where you can already adjust the throughput of the memory controller, Infinity Fabric or Uncore.
It is possible that you may encounter instability with this motherboard that is caused by too low memory voltages (CPU_VDDIO_MEM, DRR_VDD and DDR_VDDQ) under “auto” regulation. Especially with faster modules. A possible workaround is to set a fixed voltage (at 1.35 V) manually.
Power limits can be adjusted in the BIOS in two ways. One is the advanced PBO (Precision Boost Overdrive) settings, where you can adjust the current limits (TDC and EDC) in addition to the PPT limit.
And then via the “Settings” tab in AMD CBS – SMU Common Options. In this environment there is also a quick “Eco Mode” option, after which the TDP is set to 105 (with a PPT of 142 W). However, you can also customize these limits in other ways to suit yourself by entering exact numerical values. Beware though, these are in mW, so you’re writing down five (up to 99,999 mW) or six digits (above 100,000 mW/100 W).
The fan management interface (Smart Fan 6) is exceptionally rich in tuning options.
For detailed management, there are eight connectors with three fan speed profiles – Normal, Silent and Full Speed. Still, several of you will reach for the manual mode and the option to build custom curves. It goes the traditional drag and drop way with point placement, but those points can also be placed using an editable table. You can enter specific PWM values for a particular temperature into that using the keyboard.
There are eventually up to nine temperature sources that the board can work with – CPU, PCH, VRM, PCIe ×16, PCIe ×4, EC_Temp 1, EC_Temp 1 (custom thermocouples), System 1, and System 2. The CPU_fan is fixed (CPU), there it is clear, to the “ordinary” system connectors six sources can be selected (without CPU, EC_Temp 2 and System 2) and the full number is only possible for the two system connectors with the “pump” attribute.






















english version has wrong charts on the “Power draw with power limits” page (for example “CPU (no PL) avg. power draw [W], Audio encoding (FLAC) – lower is better”)
Fixed, thanks! 🙂
