Download AMD’s New Driver to Fix a Major Windows 11 Bug
A day after the launch of Windows 11, AMD released an advisory regarding two serious bugs that could reduce performance by up to 15%. Both issues are now resolved. One patch is from AMD, while you can get the other via Windows Update.
The AMD update focuses on UEFI CPPC2, or in practical terms, AMD’s favorite core feature. The Windows 11 bug reportedly doesn’t put the most demanding work on the fastest core, leading to a drop in overall performance. You can now download the chipset driver update (revision 3.10.08.506) from AMD’s website. As a reminder, this update affects all AMD processors that work with Windows 11.
Microsoft has just released a fix for the issue that many Windows 11 users are concerned about and which can reduce game performance by up to 15%. This bug is related to the increased latency of the L3 cache. This is the lowest cache level on the CPU, and increased latency means it clogs data flowing through the CPU and up to higher cache levels.
Originally, Windows 11 could almost double the latency of the L3 cache. Microsoft released a patch for Windows 11 during its normal patch on Tuesday, and we were hoping to see the problem fixed. But the update made the L3 cache latency issue worse, more than tripling the latency of some processors.
Microsoft released a patch resolving this issue for Windows Insiders on October 15. Now the fix is rolling out to the general public. To update, use Windows key + S, to research Windows Update, and select Check for updates. The version that fixes this problem should be available (KB 5006476). The update is all the more significant given the upcoming launch of Intel‘s 12th-gen Alder Lake. These processors are said to perform better on Windows 11, but bugs meant AMD entered the fight at a disadvantage.
If you have an AMD processor that works with Windows 11, you should install the new patch now. Ryzen 2000, 3000, 4000 and 5000 chips are affected, as well as Threadripper 2000 and 3000, some EPYC server processors and some Athlon processors.
After downloading the update, AMD recommends users with Zen+ or Zen 2 processors (Ryzen 2000 and 3000) to set the AMD Ryzen Balanced power plan in power options. To do this, open the Control Panelselect Power optionsthen select Choose Power Plan. You can change your plan here.
Needless to say, Windows 11 didn’t get off to a perfect start. However, these two new patches solve two of the biggest problems with the operating system. Microsoft also recently released Android apps for Windows Insiders, fulfilling one of the biggest promises of the new operating system.
