The PCB and connectors:
Tools for overclocking:
Let’s start with the elements inserted on the PCB which can be interesting tools for overclockers. They are almost inexistent on this model considering its position in the MSI range. For example, there are no physical power or reset buttons, which is a bit unfortunate in 2022, especially since the cost should not be an obstacle to its integration.
- The Debug Code Led: allows you to display a code that corresponds to the component responsible for the error during the boot. These are now displayed on the OLED screen and the list of codes can be found in the manual.
- The EZ Debug LED: 4 LEDs (CPU – DRAM – VGA – BOOT) that allow to diagnose errors during the boot of the card. If one of them stays on, it means that the corresponding component has a problem.
The PCB of this MSI MPG X670E Carbon Wifi:
Our MSI MEG X670E Carbon Wifi is equipped with the controller based on a power supply in 18 + 2 + 1. The part in charge of the CPU consists of 18 phases and on this model, no spliter, but beware the phases are placed in parallel: they are really 9. The controller is a chip Infineon XDPE192C3B.
The 18 mosfets are all 90A TDA21490 grouped in parallel by phase and thus allowing to split them. The mosfets in the power stages generate the most heat because they are responsible for the voltage conversion and delivery to the CPU from the 12 volt EPS connector.
Ultra complete connectivity:
The rear panel has the following elements. First of all the button to flash the bios from a USB stick, as well as the Clear CMOS and the Smart Button. In terms of USB ports, this MSI MEG X670E Carbon Wifi has an HDMI port and a DisplayPort. There are also two USB 2.0, six USB 3.2 Gen 2 10Gbps (Type-A), one USB 3.2 Gen 2×2 20Gbps (Type-C) and one USB 3.2 Gen 2 10Gbps (Type-C Display port).
Finally the various audio outputs and the network port (2.5G). Then we find the antenna supports for the dual band Wi-Fi. Finally, the audio part is provided by a Realtek ALC4080 chip.
