Courtesy of AMD published instructions for potential buyers to install the new Ryzen 9 7950X3D and Ryzen 9 7900X3D processors. Contrary to expectations, the process will require some time and patience from the user. It’s not just about changing the processor. According to the instructions, you need to do additional manipulations, such as: B. Reinstall Windows.
Posted on the official AMD blog instructions When installing Ryzen 9 7950X3D or Ryzen 9 7900X3D, the first dot indicates that the user must be ready to reinstall the operating system. We recommend a fresh Windows 11 Version 21H2 Build 22000.1455 (and newer) or Windows 10 Version 1903 and Build 19044.2546 (and newer). AMD advises that after installing a new operating system, it is possible (but not necessary) to disable the Virtualization-based Security (VBS) security feature. You can read about how to do this here. If desired, the user can not disable it, but in this case the system will incorrectly determine the amount of available L3 cache. Previously, Microsoft itself allowed Windows 11 users to disable VBS and HVCI security features. In addition, according to the Tom’s Hardware portal, this leads to an increase in gaming performance, sometimes from 5 to 25%.
An important step in the guide is updating the motherboard BIOS to support the Ryzen 7000X3D. Users are advised to check their motherboard manufacturers’ websites for the latest firmware versions. Fortunately, many modern motherboards for the Ryzen 7000, especially expensive models, allow the BIOS update even without the processor installed.
The company has also released a new motherboard chipset driver that optimizes Ryzen 9 performance with additional 3D V-Cache. Requires AMD chipset driver 5.02.16.347 (or higher). It can be found on the AMD website. Some Ryzen 7000X3D processor owners have found that replacing a Ryzen 9 7900X3D with a Ryzen 9 7950X3D or vice versa also requires a chipset driver update.
It should be noted that the first boot of a PC after installing Ryzen 9 7950X3D or Ryzen 9 7900X3D can take two to three minutes, even on the most advanced systems. In this case, you have to wait for the download process to finish.
The company also recommends that you set your Windows settings to “Game Mode” and update to the latest version (5.823.1271.0 or later) of the Xbox Game Bar app. Maybe some users are used to uninstalling this application to free up system memory. However, AMD recommends following their advice, as this Microsoft application supports new AMD technologies and ensures that games run on the “right” processor cores by parking those cores that the system does not need.
AMD’s prediction is backed by PC tests based on Ryzen 7 7800X3D (available April 6) and Ryzen 9 7950X3D (available now) with a Socket AM5 reference motherboard, 32GB DDR5-6000 RAM, Using Artic CPU Cooler Liquid Freezer II and Windows 11 AMD Smart Access Memory technology was also enabled on the PC and VBS was disabled.
