are they out of their mind?

WHY the hell do they have force_turbo=1 enabled??? AFAIK enabling this instantly voids your warranty!

[mikronauts]

Doubt it, as they defaulted to it and the 0 is supposed to run at 1GHz.

Also, postage is probably more for returning a 0 for replacement than buying a new 0 (once stock levels stabilize)

Nope, it's force turbo AND one of a set of other conditions which I don't know off the top of my head.

The warranty void condition is:
(force_turbo || current_limit_override || temp_limit>85) && over_voltage>0

Might be slightly different on the pi2 since there is some implied over_voltage, as I understand it.

Code: Select all

force_turbo 
Disables dynamic cpufreq driver and minimum settings below. Enables H.264/V3D/ISP overclock options. Default 0. May set warranty bit

I believe that the 'may' does not apply to the Pi B 2. The other two lines in 10586 config.txt just force 900Mhz with no scaling.

Thnx.

Fun fact:
Until about 6 months ago i uses to think the "warranty bit" was actually a physical material (like a tiny tape or paste) under the soc that would change color if the cpu was to go beyond 85c.
I had my reasons to belive that.

Lol, brilliant. What were the reasons?

1) i was unaware of an on board rom in the SoC

2) Some people referred it to as waranty "stiky" bit.

3) if the SoC was unusable how would they check the warranty status?

They can tell where the magic smoke got out

I think it can be read from the JTAG port which does not require a booted system however it is not very likely that any of the vendors would take the time to set up the equipment to do so.

Yup, i once did let the magic smoke escape from by Brev2.
Bad voltage regulator.
