Re: How to switch off IPv6 on RPi3?

Yes, it is built into the kernel, not as a module. To disable it completely just add this to /boot/cmdline.txt ipv6.disable=1 Now IPv6 is again a module by this commit 18 day ago: https://github.com/raspberrypi/linux/commit/08826d502d06b9847044714beb05db2e1b988919 I did a add iv6.disable=1 to cmdli...

Re: Raspi 3 GL Driver

Es erscheint mir plausibel , dass config.txt ignoriert wird. Der Treiber soll ja 1/3 der Firmware ersetzen , und nur die Firmware liest config.txt. ghans für mich war es a priori nicht plausibel, aber es ist ist so, auch wenn ich diese Info gerne früher gefunden hätte: https://www.raspberrypi.org/f...

Re: Overclocked Pi3: Linpack bench & Cpuburn-a53 (at same ti

Stock with just an overvolt of 1 @ 6.16, is still better then your Gflop results of 6.06. My overclocks only needed a very minor adjustment to the arm_freq to be sucessfully run (.4 Mhz) @ 6.74. ?? See run 18. 6.9+ Gflops. And it is not about a minor adjustment in frequency, it ist about what extra...

Re: Overclocked Pi3: Linpack bench & Cpuburn-a53 (at same ti

But the only question is: Does a stock Pi3 run linpack? And the answer is NO, unless you overvolt it by 2. You showed: unless you overvolt it by 4. So? And my only question to you was: Can you run linpack with you oc settings?: And the answer is NO: you had to step down frequency! And the overall co...

Re: Cooling the Pi3 with a fan.

Yes, but i meant NO oc, not even ram. What I expect you will find, is that you need over_voltage = 2 or 1 to run it at stock (=NO oc) settings. This means, that you have to overvolt your pi to get the correct answer for a linear equation. This should not hapen.

Re: Cooling the Pi3 with a fan.

As I said before, you had to lower clock from your posted settings. Why not put it the other way round. NO oc at all, NO cpu , NO ram, just NO; only over_voltage. And then lets see when you get the first correct pass. Edit: And remember: I did N=10000 with passive cooling https://www.raspberrypi.org...

Never had this, maybe because i run my Pi3 headless with gpu_mem=48. I guess you run gpu mem with 256. I would try lower it for this test to 64 in config.txt
Edit: or lower to N=6000 for the start.

No cheating. Ambient 20°C.
And the cooler isn't mounted yet, just lying planar an the CPU. Glued and vertical it will show its full potential.
