Nope, I had to order from a limited selection at the time and I can't return by now I think. Though the RAM seems excellent so far as long as the BIOS support continues or is fixed. This is the kit:
Trident Z5 RGB DDR5-6000 CL32-38-38-96 1.40V 64GB (2x32GB) F5-6000J3238G32GX2-TZ5RS
In the same boat. I have a 6600 cl32 32 gig kit sitting here that is way too old to return. replaced with a 6000 cl30 expo kit, and it works like a charm, worth every penny of $260. I paid $400 for the other kit, and it just sits.

But the GPU works in Windows?
the discrete GPU now works in both. The linux saide was a black screen. Its a 515 driver issue thats fixed in 520. I had to boot linux using IGP to downgrade to 510, as mo 520 available in my distro.

515 broke my Ubuntu 20 work laptop too with an Nvidia Quadro and Intel IGP. No more USB-C video output. Same as you I had to upgrade to 520.

So despite sleep mode being enabled at 5400 MHz, the PC fails to wake up I'm giving up on it for now and going the other direction, don't feel like running DDR5-4800. So far so good running the free Microcenter RAM at 6000, with a small voltage bump to 1.25 like the real binned Samsung 6000 MHz kits call for.

Yeah I've had no luck with sleep & memory OC yet. What a weird set of firmware/platform limitations.

Feels like a rushed launch. They really wanted to get some marketshare before Raptor Lake but it didn't work out that well for them. Should have come out of the gate with the X3D version.
Seems like typical new platform first adopters issues. AM4 had just as many problems, I know firsthand as I jumped on AM4 as soon as it launched. I was tempted to jump on AM5 as well, but decided it wasn't worth the hassle with the inevitable first gen bugs, and it looks like I was right. There are always going to be first adopters issues, they will get worked out with time, these are the rules of the game, and they're not unique to AMD. If you don't want to deal with issues, just don't buy at launch.

That is why i'm going to go RDNA 2 to RDNA 3 but will wait a year to go Zen 3 to Zen 4. Will just keep an eye on this thread watch everyone progress through the issues.

So the Microcenter 5600 MHz free RAM is 100% stable at 6000 with EXPO timings — memtest for windows, prime95 blend and ycruncher. Guess they couldn’t find bad enough ICs and had to pull them from the good pile. I’ll play around with reducing timings further for more memory performance that I’ll never notice outside of benchmarks.

I finally found some DDR5 ECC UDIMMs in stock. So I order 2x32GB. I wonder if it will work in ECC mode in Windows. I somehow doubt it will work as ASRock removed ECC support from the product page in between the time I ordered the motherboard and now. But I continue the experiment regardless.

I'll post an update for anyone else curious when it arrives.
It doesn't work in ECC mode in Windows. This is an ASRock X670E Steel Legend which Level1Techs said supported ECC based on ASRock's earlier, and apparently erroneous, spec sheet.

3 = No error correction

Edit: there is a setting to enable ECC mode (defaults to Auto). Enabling that and seeing if it'll boot.

Edit 2: it won't boot with ECC set to enabled. Not a good sign. I'll try flashing latest UEFI.

Edit 3: New UEFI didn't work. One stick didn't work. Just no way to get it to boot with ECC enabled. Cleared CMOS to allow it to work in auto mode.

Conclusion is that ECC doesn't work on some ASRock AM5 boards that as late as early October listed ECC support. And have a BIOS option to enable ECC.

I would say AM5 at launch has less bugs than AM4 did
Very few RAM kits ran at rated XMP settings on AM4 at launch, and very few boards did it.
Most SK Hynix kits were hated by most boards.

In contrast, most kits seem to run at XMP / expo on AM5.
On AM5 we are nitpicking about tightening the timings.

AsRock was the one leading the way on memory compatibility early on AM4, Gigabyte seems to be leading early on AM5.
Furthermore, the UEFI updates are much mor frequent on AM5 launch.
The only downside that I see on AM5 launch vs AM4 launch is the loooong boot time.

Would be interesting to see what the other folks think.
Smoother new AMD socket launch, AM4 or AM5?

It's pretty close. My first AM4 board wouldn't run memory at the rated speed at all. It was 2667MHz or less only. With AM5 memory works in theory. But I don't want to run at XMP because it disables sleep states. So technically better but practically the same.

And AM5 boards have more things that can go wrong. The integrated graphics, wifi and bluetooth were all not available or common at AM4 launch. And I've had (minor) issues with bluetooth and the integrated graphics when I tested.

Am5 boards don't have an igpu the cpu does. Like intel. Wifi is intel on all the boards I've looked at, and bluetooth is intel too. Wifi and bluetooth issues would be an intel problem. One of Intel's nics is gutter trash and on every motherboard system sold unless they use equally gutter trash that works more often like realtek or marvell.

So? The Zen 1 IMC on the CPU was responsible for a lot of AM4's early problems. Still was seen as a platform issue.

And the board I'm using has an AMD branded RZ616 wireless/bluetooth adapter. So I won't be blaming Intel for that. I had to disable it in UEFI to avoid wake from sleep failures.

Imc is for memory. This was addressed over time with bios update. the rz616 is a mediatek and amd joint project. It's a very new product. There will be issues. Intel's wifi adapters weren't pristine when they came out either. Install an Intel adapter.

Obviously the memory controller is for memory. The question was which platform launch was smoother. And alleviating the problem BIOS updates over years still means the AM4 launch was rough.

And adding another adapter to work around launch problems is exactly what I'm talking about. That's part of rough launch too.

I don't understand what the intent of your post was.

I don't understand yours either. It's going to be a long time until AMD has a smooth launch. They're getting better, but it'll take time.

Someone asked which launch was smoother AM4 or AM5. And I responded that neither should be described as smooth.

But yeah you can pray and hope they fix the problems. They probably will. But it's no guarantee. And I wonder how many years pass before I can enable XMP and sleep states. What a luxury...

If you're not happy pawn it off and buy intel.

No. Simply put I expect them to fix it ("They probably will"). And AM4 was rough too. But if AM5 follows the AM4 trajectory then I'm fine with it. A B350 board I bought 5.5 years ago can work with nearly top end gaming CPUs (5800X3D).

That doesn't magically make this a smooth launch. It's just how AMD launches go and we all knew. No point trying to hide it when does indeed have problems.

If you have an issue you should contact AMD directly. Posting on some message board that has no relation to AMD won't help you out much. If you have an issue with the usage of the word smooth take it up senor ruiz many posts up.

What board do you have?
Did you install the AM5 chipset drivers?
What WiFi drivers did you install?

I am personally very pleased with the MT7922 WiFi, but then, I am partial to MediaTek.

ASRock X670E Steel Legend.
Yes to chipset drivers. The wifi drivers were those from ASRock's website: ver:1.723.0.164 and ver:3.3.0.467. But I've disabled it in the BIOS.

It is just fair warning to potential buyers that this is a platform that currently doesn't support sleep with XMP enabled and also has 50 second post times. And somehow people find this to be fine. The board has great reviews. If you ask other owners they have that same problem. They just don't care? Somehow I'm the only person that finds this to be a bad experience... weird.
