Fix for Windows 11's AMD Ryzen L3 cache issue arrives in beta

Windows 11 test build, 22000.282 fixes this slowdown, but CPPC2 problem remains.

Read more.

I won't upgrade why change when it's working perfectly now. They will struggle with this for a while I think.

From what I've read and viewed on various sources M.S worked closely with Intel for their newer chips but not AMD , smells of Intels dirty trickery again. Also that AMD were left to find a fix and that M.S. came back with one that made matters worse but apparently now eorking with AMD on this. All this should have been ironed out equally between the big players before releasing this latest screw-up of an O/S.

It wouldn't surprise me if there weren't a grain of truth to that. Wouldn't bet money on it, but wouldn't surprise me...

Heh, i just this morning reverted my PC back to windows 10 :)

Why i was trying it is because theres a very annoying bug in win 10 that win 11 fixes
- If you have dual monitors with mixed cable types (DP and HDMI for me), if you leave the PC long enough to power off the displays, theres a roughly 80%+ chance of all desktop windows being shoved onto one screen when you wake it, meaning you have to manually drag all the windows back. Gets annoying very fast!

But i found all the w11 bugs and other annoyances just too much to cope with in the end...

AIDA64 Official reckons that the patch works well for AMD Ryzen users:

"We've installed and tested the upcoming @Windows patch (KB5006746) and it seems that it fixes the L3 speed issue that affected the @AMD Ryzen processors on the initial release of Windows 11."

I believe that is a Displayport bug, Got dual DP monitors on works machine and have the same annoying problem. Also sometime will only initiate one screen have to power off and repower the blank screen to get windoze to replace everything correctly.

Well i confirm that windows 11 fixes that bug entirely for me. Even had one instance of the displayport screen taking a full 15seconds to re-initialise, but when it did all the windows just moved back to where they should be :)

Just need to wait for MS to fix more of the annoying stuff then i'll try again.

Personally only experienced one issue with Windows 11 so far - Finger print reader was ignored following a resume but otherwise its been ok for me so far. Looking forward to this fix though!

I haven't had any issues with Windows 11 on my laptop.

As soon as I read the word, 'Windoze', all respect is lost for the person posting. If you think it's rubbish, then more fool YOU for using it. You have choices. Grow up, or try to stay cool whilst sounding silly.

Imagine it... a NEW os having issues over hundreds and hundreds of different computers. Heck, Apple has issues with only a few.

Ill upgrade with next system I build, simple as that, besides they hate some of my High End devices...

Yeah, backhanders are almost certainly involved. There's no way you redo the scheduling and genuinely forget to test common scenarios on what is currently the most popular family of desktop CPUs.

I can't say I've ever seen that on W10 myself, and I have 3 monitors permanently connected, one DP, one HDMI (TV) and one DVI (now needing a DP adapter, but just DVI on previous card).

I'm not upgrading anyway. My PC isn't compatible (I know I can circumvent that) but with a nerfed and less efficient taskbar than the W10 one I'll not be swapping until that is either changed or W10 support ends in 2025.

My Ryzen laptop is working well with Windows 11, I can notice every now and again it will have a moment where it seems to slow down but definitely nothing that bad.

Looking forward to the AMD patches later this week but, in the meantime, W11 is working well IMO. I can still run Far Cry 6 and Flight Simulator with no issues. Really don't get all the negativity or people saying the launch has been a dog's dinner.

Would have been nice if Microsoft actually fixed the many issues that Windows 10 still had and stopped making customers beta test their buggy software. With Windows 11 it will be the same stuff all over again. Microsoft will never learn and never change. I will not upgrade to Windows 11 and instead completely switch over to Linux when I have to.
