MSI Preps RTX 50 “Extreme OC” GPU, As Afterburner Dev Receives First Sample with Advanced Overclocking Features
It appears that MSI is developing its own “Extreme OC” variant based on the RTX 50 GPUs. According to Unwinder, the developer of MSI Afterburner, he has received working samples of these future MSI RTX 50 GPUs, which include advanced overclocking features such as “Unlocked Extended Voltage Control.” Consequently, the upcoming BETA versions of Afterburner will feature an extended suite of overclocking options.
In September, Unwinder revealed some initial details about the next beta release, which was scheduled to be released that month. The new version would add support for MP2988 and MP29816A controllers (PWM). These PWM controllers are found on most RTX 5090 and RTX 5080 GPUs but cannot be used due to NVIDIA’s restrictions. However, it seems MSI has worked with NVIDIA to unlock the capabilities of these PWM controllers through certain alterations.
Autumn started, and September brought around the MSI AB beta with MP2988/MP29816A support announced in the previous post. We have first working samples of future MSI 50×0 graphics cards with unlocked extended voltage control and are currently testing a new beta with them.
On such future MSI cards, you’ll get extended triple channel voltage control and monitoring. Triple channel control includes core voltage control (direct PWM access mode with +-100mV range instead of the default NVIDIA’s GPU boost voltage control on reference design cards, which only allows you to set the voltage between 0 to ~20mV), memory voltage control, and aux (MSVDD) voltage control. In addition, it will unlock VRM temperature monitoring (on-die MP29816A temperature sensor).
Sadly, as mentioned above, these features won’t work on current reference design 5080/5090 cards due to NVIDIA’s restrictions.MSI Afterburner Dev (via Guru3D Forums)
These features will only be available on these future “Extreme OC” designs from MSI. Moreover, MSI Afterburner will also support triple-channel voltage control and monitoring. The Triple-Channel voltage control allows direct PWM access mode with a range of +-100mV instead of the current default mode, which restricts you to 0 to ~20mV (0 to 100%). There will also be onboard VRM temperature monitoring through the on-die MP29816A temperature sensor on these new GPUs from MSI.
These features will only work with the new MSI RTX 50 cards designed for “Extreme OC” and won’t be available on existing models. As for the model, it looks like this “Extreme OC” variant could be a new Lightning RTX 5090/5080 series graphics card.
