MSI Afterburner

A powerful utility from MSI designed for overclocking NVIDIA and AMD graphics cards. With this program, you can adjust GPU and video memory voltage, core clock frequency, control fan speed, and monitor your graphics card in real time—such as its current temperature, clock speed, voltage, and more. It supports NVIDIA GeForce 8X00 series and newer, as well as AMD Radeon 3000 series and newer. Additionally, users can test their GPU’s stability using the MSI Combustor tool, which is based on the popular FurMark benchmarking engine. MSI Afterburner allows adjustment of GPU and memory voltage, monitoring of 2D/3D mode switching, control of the GPU’s cooling system, creation of up to five custom profiles switchable via hotkeys, FPS monitoring in 3D applications with on-screen display and system tray support, full support for 64-bit applications, customizable interface themes, and the ability to record the best gaming moments and share them with friends. In version 4.6.5, MSI Afterburner added support for NVIDIA GeForce RTX 40x0 series GPUs, voltage control support for NVIDIA GeForce RTX 3060 Ti models based on GA103 and GDDR6x, support for AMD RADEON RX 7900 series GPUs, and total board power monitoring for AMD RADEON RX 7900 series GPUs. The hardware monitoring module now supports Intel Arc GPUs, though overclocking and tweaking of Intel Arc GPUs is currently not supported due to Intel’s hardware API limitations to x64 applications only. Experimental support was added for Intel 13th-generation CPUs and AMD Ryzen 7xxx CPUs. CPU usage data sources in the hardware monitoring module were switched to an alternative implementation based on NtQuerySystemInformation(SystemProcessorIdleInformation), as the traditional idle-time reporting method in SystemProcessorPerformanceInformation is broken in current Windows 11 22H2 builds. A fallback was added for the non-functional fixed fan speed programming API (Overdrive 5–compatible fallback) for older Overdrive 7 GCN GPUs on AMD drivers 22.5.2 and newer. A configuration file switch was introduced to disable the built-in reliable voltage control API for NVIDIA GeForce GTX 9x0 GPUs and force the legacy P-state 2.0 voltage control API on such hardware. Advanced users can use this to bypass voltage control restrictions on NVIDIA Maxwell GPUs in driver versions 515 and newer. The voltage/frequency curve editor formula parser was improved with data format conversion, rounding, and min/max function support. Bus clock monitoring based on OCMailbox was added for Intel Skylake and newer CPUs. Unlike legacy timestamp-based estimations, OCMailbox supports monitoring of overclocked BCLK, though access is blocked by the OS when HVCI is enabled. The SMART.dll monitoring plugin was enhanced with support for NVMe device temperature monitoring, including secondary controller temperature for some Samsung NVMe drives. The default clock frequency limit in the voltage/frequency curve editor was increased to 3.5 GHz, though limits can still be adjusted manually in the configuration file if needed. The update server URL was changed to a new address within the update-check system, as the old server has reached its end of life.
