So Canary does that mean that there's no way to troubleshoot the dead chip? What are the terms for warranty service in that case?
its a dead chip. thats why the blades are rated at 10.0 Ghs and everything above that is "freebie". that allows for up to 2 chips to be bad and still be over 10ghs.
i've seen about 5% of blades have bad chips. one is not so bad. more than one you may have an issue with your PSU.
