Isn’t there a Ryzen issue I read?
Think - may be wrong - issues are said to be with AMD chipsets as a whole.Isn’t there a Ryzen issue I read?
Windows 11? Pfff … I was running Windows 95 YEARS AGO …For those early adopters of the now live Windows 11, a question:
Is it behaving and is Elite OK under the O/S?
Not sure if serious ….It was already reported windows 11 worked fine (with EDO)
No idea why you doubt that. MS has always been very good with compatibility. They need to support millions of applications some over 20 years old
Really? Hmmm … next they’ll be rewriting it based on UNIX … can you resize a DOS CMD window yet?The start bar is centered and the windows have rounded corners
Obviously you're right about the L3 issue being correct. However, I have run several programs that use both CPU and GPU "to the max" like Resolve and I have done my own benchmark setups in those, without seeing any performance issues. My philosophy being that if it doesn't impact the work I normally do, then I'm fine. Also a benchmark like Cinebench shows the same performance as in 10 (with the normal fluctuations). I haven't done any statistics. In R23 I got ~22.500 running 10, and running 11 I get ~22.800 (mc).The L3 latency problem is universal, and the lack of CPPC acknowledgement is highly likely to negatively impact lightly threaded performance on many-core Ryzens. You may not notice it if your apps are GPU limited (which will be the case for most games and GPU benchmarks), or relatively insensitive to the performance of the memory subsystem and/or multi-threaded enough to make the lack of CPPC moot, but the issues are there.
Obviously, if you like the OS and the current issues are imperceptible to you, there is no reason for you to not continue enjoying it. I would expect a fix soon...though I am surprised it wasn't addressed prior to launch (as the L3 latency issue was well known among AMD enthusiasts, but put down to preview build teething problems).
Not going to bother with win 11.
Built a new machine Mar 2020. Win 10, Asus Prime Z390-P MB, I7 9700 and an RTX 2700 super, it's not win 11 compatible. No tpm.
What a joke.
I like sharp and jaggered corners for my windows. Is there an option to correct this?The start bar is centered and the windows have rounded corners

On the way I tried to install Linux. I hate M$ by heart (as much as I love Anthony from LTT), having experienced the good old days of "Hey I wrote this software, if you can use it go ahead and do so for free". Then Bill Gates came along and wanted money for his "crap". I would love to switch to Linux. Installing Linux was a mess though. I tried several distros. Changing stuff in the bios. My GPU not being recognized. Ending up with a boot sequence that just rebooted in an endless loop. When I finally got it to work (I used to administer Unix based SGI computers), there were simply too many things that didn't work. Sad that.
Most likely you can enable TPM in BIOS, as CPUs have integrated it since 2015 or so. The option ("PTT") ist rather hidden in the Advanced menu, but it works even for my ASUS ROG Z270H from 2017 (which even has an empty TPM slot on board). https://www.asus.com/microsite/motherboard/ASUS-motherboards-Win11-ready/
Unfortunately, I have an i7-7700K which is not compatible :-(
Strange that the L3 issue is confirmed by AMD, even though I have found no performance issues running benchmarks (on a 3950x). Does anyone know of any game/software where the issue shows?
The other known issue with Ryzen, "preferred cores" being broken makes no difference for anyone who OCs. Once you lock the clocks "preferred cores" isn't used anywho. I have only run Cinebench R23 multicore (not single core). Normally I don't OC, but leave it as is, and then I use fan profiles to make the PC quiet.

Yes, it depends on what you use your PC for. I haven't gotten around to running EDO on 11 yet. Might get it working today (I need to install it and my X52 drivers). Since EDO seems to have some issues with multitasking, it might show up there. The main reason I bought the 3950x was that I use astronomy software that only uses CPU (and mostly scales reasonably well).It's been easy to see in synthetic benches for a long time: Source: https://www.reddit.com/r/windows/comments/oamp05/cache_l3_completely_off_on_windows_11_with_amd/
The real world tests that seem most affected are archival software (WinRAR, 7-zip, etc) and CPU limit high-fps/low-resolution gaming, with Rocket League being one of the commonly cited outliers that is up to 15% slower on Windows 11.
Much of the OCing on recent AMD parts involves manipulating PBO, as that produces the best lightly-threaded (and thus gaming) performance. CPPC preffered cores can help or hurt here, depending on other factors. It helps my ryzen 3900X and 3950X series parts, because the preferred core order actually corresponds well to the highest boosting cores on my samples. It doesn't do much for my 5800X sample because with an optimal per-core curve (something the 3000 series doesn't allow), my least preferred core is actually my fastest core...CPPC can measure actual performance delivered and adjust the feedback it give the OS, but it doesn't always work.
Fixed all-core or per-CCX OCs are slightly faster than PBO for heavily threaded work, but tend to fall well below where boost clocks would be for PBO/auto OC.
For example, my 3900X is good for an unconditionally stable 4.2GHz all-core OC, and this performs great in multi-threaded loads, because PBO will rarely boost past 4GHz in such scenarios. However, it will regularly boost to 4.5GHz in lightly threaded loads with custom PBO settings, which is faster for gaming. The differences with my 3950X and 5800X are even more in favor of PBO.
I've read that choosing browser other than Edge makes selecting your default browser unnecessarily obtuse... would that be true?
Normally the CPU runs at ~3850 GHz (I remember when MHz was a thing)
Yep. My bad. Make that MHz and KHz, the latter being C64 @ 985KHz. Still it was a lot faster than many PC running EDO. Sort of.That's definitely MHz (10^6, short scale millions, of cycles per second), not GHz (10^9).
