How do I find out if my Pi's warranty is voided?

Question

How do I find out if my Pi's warranty is voided? I overclocked my Pi, but I didn't use the force_turbo setting.

Answer 1

From this document (The Foundation doesn't handle warranty returns):

Newark element14 has no obligation to repair, replace, or provide refunds in the following instances:

• If the alleged defect arises because Customer has altered or repaired the Raspberry pi without the prior written consent or authorization of Newark element14
• If Customer did not follow any applicable instructions for proper storage, usage, or maintenance of the Raspberry pi
• If Customer has failed to notify Newark element14 of any defect where the defect should have been reasonably apparent on inspection
• If Customer fails to notify Newark element14 of the defect within 12 months of Newark element14's shipment of Raspberry pi to Customer.

Since the Raspberry Pi Foundation has declared the "standard" overclocking options safe, overclocking no longer voids your warranty:

Since launch, we’ve supported overclocking and overvolting your Raspberry Pi by editing config.txt. Overvolting provided more overclocking headroom, but voided your warranty because we were concerned it would decrease the lifetime of the SoC; we set a sticky bit inside BCM2835 to allow us to spot boards which have been overvolted.

We’ve been doing a lot of work to understand the impact of voltage and temperature on lifetime, and are now able to offer a “turbo mode”, which dynamically enables overclock and overvolt under the control of a cpufreq driver, without affecting your warranty.

So no, there is no warranty "bit" that is set anymore.

Answer 2

In Raspberry Pi 2 and newer, you can check the warranty bit by looking at the revision code. There are two ways to look at the revision code:

cat /proc/cpuinfo

and

vcgencmd otp_dump

The documentation here shows what the revision code is contained within bank 30 of the otp_dump.

The newer style revision code places the warranty bit in the seventh bit position. If it is a 0, your warranty is intact. If 1, it has been voided by overclocking.

Answer 3

It depends on where you bought it. Element 14 for example will replace it unless you alter the device in some way. If you overclocked the device using the built in method you should be fine.
