My Pi3 (non plus) is super unstable with this new June 1 firmware. It immediately fails the memtester and sometimes does not boot at all.
My config.txt oc settings:

Code:

over_voltage=8
arm_freq=1280
sdram_schmoo=0x02000020
over_voltage_sdram=4
sdram_freq=570
gpu_freq=470
force_turbo=1

Smp1, I'm not an expert but your over_voltage setting seems a tad exaggerated, is it useful?

Does adding safe_mode_gpio=16 to config.txt and rebooting make any difference?

What exactly is a “borderline” RPi3+ board?

There are a small percentage of pi3+ boards that have stability issues at arm_freq=1400 and/or sdram_freq=500.
They generally need a slightly higher voltage at certain temperatures to become reliable, so we've been tweaking these rules.

No, still very unstable.

After updating to #601 my Pi3 (not plus) no longer boots I get this  after a reboot  and another reboot 

So I downloaded #530 and manually copied the files and everything worked.

I tried #601 again and got this 

Went back to #530 the same way

 arm_freq=1280 require that much voltage on my Pi3. Otherwise it does not pass torture tests.

Can you paste the contents of your /flash/config.txt

If you are overclocking your RAM, try removing your RAM overclock and see if that helps.

I have an RPi3 with the following sdram overclock:

text:


sdram_freq=580

over_voltage_sdram=5

sdram_schmoo=0x02000020

and this was 100% stable with older firmware, but now crashes with #0601. Removing the overclock allows the RPi3 to boot with #0601 firmware.

Maybe this sdram overclock is no longer stable with the new rules in the #0601 firmware and I need to revalidate it, or it's a bug in the new firmware.

It looks like sdram_schmoo setting in config.txt is ignored in new firmware.

Here is my config.txt.  I commented the last 3 lines and was able to successfully boot #601

When I turn off the Raspberry PI 3 model B+, the USB ports are not disabled (0530 and earlier). My external USB DAC stopped shutting down automatically. Although with 8.2.5 everything works - DAC will turn off automatically after switching off in the 8.2.5. 
But when measuring the voltage on the USB with a multimeter in the off state "0", in the switched on "+5V". Something does not allow the ports to completely shut down. On Raspberry PI 3 also works as it should.

Resolved. I added a string "max_usb_current=1" to the config.txt, now everything works as it should.

Is there anything that can be done to solve the issue with artefacts in livetv when bt audio is activated?
I tried the following settings: deactivate wifi with

Code:

dtoverlay=pi3-disable-wifi

and set audio resample to middle but no improvement so far.
Artefacts are visible when watching 1080i50 and also 720p50 channels.

Does this happen with 8.2.5?

Wifi diable in LibreELEC Settings.
I noticed that the Pi is not Powerfull enough (or whatsoever) to capture and watch Live-TV at the same time. I do use 2 Pi´s nearly no Problems at all. (about 0.5% artifacts)

It looks like sdram_schmoo setting in config.txt is ignored in new firmware.

Based on testing that sounds plausible - 580Mhz/+5/schmoo=0x02000020 is stable in #0531, but only 510Mhz/+5/schmoo=0x02000020 is stable in #0601. If the 580Mhz overclock were marginal then you'd expect maybe 570Mhz or even 560Mhz to be rock solid, but having to drop down to 510Mhz suggests that maybe schmoo is being ignored.
