Windows 11 TPM Requirement? Bypass it in 5 Minutes

[stinger608]

I'm running 11 on a 4790K system with a GTX970 and it runs great.

I was a bit surprised at how well it runs and as others have said, it's a bit faster than 10.

What about drivers, though? AMD hid all their drivers for 'incompatible' HW from their website.

So, for example, there is no patch for the latency issues of the $L3, which would make bypassing the requirements pointless.

To be fair, that bug basically affects Aida64 and nothing else

Download the Windows 10 Drivers. Install, enjoy. The Windows 10 drivers, AFAIK are 100% compatible with Windows 11. I have installed Windows 7 drivers in Win11 with no issues.

Exactly what Lex stated. I just downloaded the win 10 drivers.

I'm afraid to do so brcause AMD's release notes state explicitly 'Restores intended function and behavior of UEFI CPPC2 (“preferred core”) in Windows® 11 build 22000.189 (or newer) on AMD processors.'
AFAIK this is the fix for the $L3 latency issues in Win 11.

Given that installer is most likely set to ignore older CPU, I wonder if it's worth the risk of wasting my time experimenting.

So, has anyone tried Win 11 on 2xxx mobile APU from AMD? If so, any issues with the latencies?

Hmm, has it been confirmed officially? It stirred both AMD and M$ quite a bit.

With the current build, AFAIK, you should not have any problems.

I will skip this "pleasure". Windows 10 is just fine and doesn't need a replacement at this time..

I agree, and while I have modern machines to fully test Win 11 on, they are all production ones.
I was wondering if Win 11 is somewhere near production-ready (I won't even consider it for anything mission-critical), and I only have some 2700U (Zen+) laptops to spare. And this brings us back to my original concern, thus completing the vicious circle. F*** M$!

 

[bug]

I wonder, and nobody has talked about, whether Win11 improves the DPC problem in Win10 in any way.

I agree that we really need a deep-dive into Win 11 and a serious comparison between the various performance aspects of both OS.
Oddly enough, currently there are only bits and pieces of such comparisons on the web.

I wonder if TPU will delve into this anytime soon?

 

[lexluthermiester]

Nobody is talking about it because it's a small and mostly isolated problem that has to do with vendor drivers and not the OS itself.

That's interesting: https://www.hardwaretimes.com/windo...via-iso-file-no-additional-workaround-needed/

Author claims were not backed by citations but it still sparks some hope.

I've tested standard, unmodified Win11 ISOs on first gen Ryzen, no go. Whatever ISO he's using is either something brand new from microsoft I haven't had a chance to test yet, has been modified without him knowing or he's just full of crap. Given the date on that article, I'm leaning in favor of the last option.

I disagree. It's a flaw in the OS when one rogue driver can ruin the party for everyone.

Given the behavior exhibited by the problem, I doubt it's a flaw in the OS or more of this would be happening. It's not happening a lot which lends to the notion that it's careless or flawed driver coding. Either way, it's not a widespread problem. It needs a solution but is not something 99.9% of Windows users need to worry about.

Sure, that's why you can find like million tools to measure DPC latency on the net. Because no one was hit by this
I'll admit, I wasn't hit until I tried streaming from my laptop (who would have thought an i5 Skylake isn't up for streaming FHD?). Streaming seems to be the thing that is most affected by the problem, because it's usually triggered by network drivers and you can't disable network drivers while streaming.

And now that I went for your red herring (whether the issue is widespread or not), I would like to circle back to the flaw in Windows: a driver cannot be allowed to hog CPU time at its own will. That's a flaw. I don't have high hopes for Win11 fixing this, but it would be something that would compel me to install it (my holiday vacation came and went, I still haven't found the time to upgrade my laptop )

That doesn't mean it was a widespread issue.

I'll admit, I wasn't hit until I tried... an i5 Skylake

And there it is.

because it's usually triggered by network drivers

Update your network drivers or try a different version of them.

And now that I went for your red herring (whether the issue is widespread or not)

The term you're looking for is " Reality ".

I would like to circle back to the flaw in Windows

Then start a new thread. Said in depth discussion doesn't belong here.

It's pretty common with intel drivers. Can you try with a different interface, e.g. Realtek ETH or similar?

Edit: just search for 'ndis.sys and tcpip.sys high dpc' and behold - it's a real shutstorm. Here is a brief example: https://answers.microsoft.com/en-us...s/bd733108-8589-41d3-b780-6d394b0f0a33?page=4

To summarize, it's lazy coding on M$' side, but @lexluthermiester is right; that's a bit of a threadjacking.

I mean, i had serious network lag spike latency issues... caused by something on my network.

Shocking twist, an OS or driver change wont fix that - you need to investigate your networks with wireshark,

Jesus, why do all of these types of discussions always turn into an argument with several members???????????

So damn tired of reading interesting threads that end up in a pissing match!!!!!!!!!!!!!!!!!!!!!!!!!

Welcome to the internet

Part of it is people diagnosing fun issues and having it stuck in their brain until they work it out eventually (if they ever do) and the other part is Maslow's hammer

Give someone a hammer, they try and bash every problem.
Give an inexperienced techie what they THINK was the solution to their problem (but usually a coincidence) and they'll try and hammer that solution into everyone elses problems

Not trying to be anyone's lawyer but @bug is describing a high DPC (Deferred Procedure Call) latency spikes on higher network load. This has nothing to do with network latency per se.

Read the link in my sig, my smart TV was sending faulty network packets causing local DPC latency spikes

D-yikes! That's why I drop invalid packets even in LAN (firewall filtering).

On the 'topic' - I doubt that many people out there (me incl.) are having faulty TV's on their networks, but it's worth it to check for everything.
