Dead die?

This is an October Jupiter that's been running from 24/7. Noticed I have a dead die. I already increased the SPI voltage all the way up to 3.3V and it wouldn't kick it on. Then I slowly increased the individual die voltage to the MAX, which is +.1465. Didn't awake up the die either. Is there anything else that can be done to kick this die on?  I would really thought that the rig would last a lot longer then 8 months.

My October Jup is dying  - every now & then it stops hashing and says pool URL invalid in PuTTy.

a few reboots/restarts/curse words later and it usually gets back down the shaft

but its happening more often and requiring more effing about to get it back hashing.

in fairness it could do with a scrub - but that can wait.

how about them refunds?
