seems ok, dont recall w10 numbers tho.

Installing the Windows Update and new chipset drivers puts everything back to normal for me as well.

I don't think the latency fix is in the update channel yet. Are you on a dev branch or smth?

It workd on my work computer (Ryzen 5 3400G)
L3 Cache went from 16.6 to 9.9ns
i'll try at home later.

bugI don't think the latency fix is in the update channel yet. Are you on a dev branch or smth?

Yes it is. I am not on the dev branch and still got the update pushed.

Glad to see its fixed, but why the hell wasn't something this serious picked up 6+ months ago?

Windows 11 "launch" is just more beta testing for Microsoft's benefit with unwitting consumers as the guinea-pigs.

Great news. I'll probably wait for one more patch Tuesday to upgrade

…….until the next patch update…….

we got hit with print nightmare yesterday morning. 24 hours later still no printers…..

Hi,
Latency is still a sad joke though.

Chrispy_Glad to see its fixed, but why the hell wasn't something this serious picked up 6+ months ago?

It was actually reported about 6 months ago.

The weird part is neither Microsoft, nor, more telling, AMD saw fit to push for a timely fix.

Just updated my Home RIG, its night and day... Running Way better

bugSo you're telling me AMD simply repackaged their Win10 driver and called it day?
Something was obviously amiss, otherwise AMD didn't have to issue a new driver.

Raises the question of what kind of testing AMD (and Microsoft) did if they didn't notice that the preferred core detection wasn't working right. Makes you wonder what else they missed.

Only thing wondering is why so many informed people in a tech enthusiast forum defend the MS falls and evil tactics that have affected us customers so many times... :shadedshu:

FlankerWell there goes the conspiracy theories

What conspiracy theories? Please, tell. I thought, that MS was just lazy and forgot to copy core-scheduler from newer versions of W10 to W11...

an Update Preview is not a "beta," but a software update released ahead of its designated "patch Tuesday"

Indeed. The "patch Tuesday" updates are the betas. The "Update Previews" are the alphas.

Later edit:

After reading this on my desktop I decided to see if there are any updates on my laptop, on which I made the mistake to accept the "upgrade" to Windows 11. There was some kind of Cumulative Update available. I installed it, the system tried to reboot, and now I'm staring at a black screen for the last 10 minutes. The fans are still spinning. Keeping the power button down doesn't seem to shut it down, for some reason. Yep. Beautiful updates, Microsoft. Just beautiful.

Even later edit:

I had to disconnect the laptop from the docking station / external video card. Then I was able to power it down. Reconnected it to the docking station, powered it up, then it installed the update.

Then I checked for updates again. Doing that automatically installed an "Update Preview" for .NET, without asking me, and now it's asking for another restart. Sigh. Very tempted to roll back to Windows 10.

That's literally what the article you are commenting on is about. It's now in stable.

latest 21 october fix better than insider release........ good fix for me...

R-T-BThat's literally what the article you are commenting on is about. It's now in stable.

Yeah, yeah, I was under the impression it was queued up for a November release. My bad.

Because I don't like seeing a party accused based on thin arguments, just because of stuff that happened in the past. And that does not mean Microsoft alone, I will defend Intel, Nvidia, AMD and whoever else I may see accused for no good reason. I would even defend Apple, but I rarely read articles about their crap products. Hope that helps you put an end to your wondering.

Raiden85I've updated to the latest MS L3 patch and installed the latest AMD chipset drivers, speed is looking good here.

Not good lol... your memory latency is so high. So is ur l3 layency. It should be 10 to11 ns.

Its also not fixed for 5900x @W1zzard

@btarunr

Please test 5900x and 5950x

5800x does seem to have any issues

+5 latency is huge and the l3 read, write, copy speeds as well.

The win patch does work but amd chipset driver ruins everything else, though it fixes cppc


Attached img is win 10

Edit, the 3rd img posted in this article also confirms a 4ns increase in memory latency. Am not surr what the impact is tho..

Is it still a free upgrade from 10pro?!

Memory latency with these sticks has always been high even on 10 so that's not 11s fault. Even with the same 4x 16GB sticks with a 8700K/9900k they were in the 50ns range so high even for Intel.

bugHa, I called bad driver for AMD! I was partially right.

Its still bad. Check my benchmarks. Amd driver ruined more with fixing cppc

Bro check my screenshots. My latency is fine without amd chipset drivers, infact it did 58ns with just 4.8ghz. Also l3 bandwidth was better.
Installing the amd driver again uses a higher boosting core at 5.1gz but latency insreased by 5ns to 63ns and l3 bandwidth is all over the place.

I also posted my w10 bench which is quite aimilar to the one without amd chipset driver.


Amd needs to get their stuff together.

roberto888Before and after.

Oh my god, that 4.6GB/s write is the worst result i've seen, period

That's the kind of performance that causes issues, if it was constant

I'm not sure it existed then - they're adding in new code for alder lake, changing the OS at a fundamental level, and broke something without noticing (they dont exactly run L3 cache benchmarks on every CPU model that ever existed by default)

Then they had to fix it, WITHOUT undoing the changes for AL

Personally never had a good time with AMD drivers in general, when Windows updates are thrown in the mix it is even worse (mainly with alpha/beta/insider etc)
Especially the AMD RAID drivers and software.

Meanwhile on Gentoo Linux:

Here is my results!
