Clearly...Reboot the machine until the "CoreFreqs" all have a value..... (The CoreVolts will also have a value at that point)
There are a number of folks that have had heat issues including re-thermal pasting their chips.
Where are you running this? In a cool environment?
Also if your machine is out of warrantee, open it up and make sure your fans and radiators are clear of dust....
The core volts for CTA0 core 2 are showing as 0 because i have that core disabled,, If I dont disable the core the entire half of the machine wont hash, it just flashes all leds on and off in 2 second intervals, while the fan on that side revs up and down in unisom with the leds flashing, like its trying to boot up but caught in an infinite reboot,, in order to allow for core one to hash I must disable core 2,, after core 2 is disabled core 1 hashes normally with normal temps.
All 3 remaining cores are hashing 100% fine, powerstepping at 9,
I have long since opened my machine,, cleaned it many times,, never had a problem till I changed the thermal paste. And even now after changing the paste its fine. Just down the one core, which sucks.
I sold the unit today on ebay for a very cheap price. SO im over it, moving on,, Im gonna miss my terraminer though,, It was my first machine,,, first of many. Lots of growth these past 3 months.
Thanks for trying to offer some advice.
