What denial? What head in the sands?? They worked their asses off to improve the issue, and ignored the FUD. The extra fans just waste electricity. The temps quoted from Bertmod were from the VRMs not the ASIC. Please explain what trainwreck exactly? They, in a week have delivered more hashrate than BFL have to date, and more boxes than Avalon ever achieved. They have just released an update that massively improves hashrate. It was a firmware, not a cooling issue. One week. Fair enough if you don't want to deal with them again, their engineering partners on this project think they are incredible, really. That's not hype.
I went from ~410 to ~510 BY COOLING
In my testing, lower temperature doesn't seem to increase the performance of my Jupiter. I've been trying to figure out why my hashrate dropped overnight and decided to remove the case and point a big fan at it which dropped my temps from:
ASIC slot #1: 51.5 ℃
ASIC slot #3: 57.5 ℃
ASIC slot #4: 63.0 ℃
ASIC slot #5: 54.0 ℃
to:
ASIC slot #1: 42.5 ℃
ASIC slot #3: 47.0 ℃
ASIC slot #4: 42.0 ℃
ASIC slot #5: 35.0 ℃
but this did not improve my hashrate at all. Right now I'm not sure what to think about my unit's behavior:
As you can see yesterday it held at around 530GH for around 12 hours before dropping to 450GH over night. After applying .95 it increased back to 500GH but I can not get it back to the 530GH levels I was seeing yesterday even with extra cooling and reverting back to .94. It did this the day before where it was running fine before dropping to 450GH but a simple reboot returned it back to 500+GH. I guess I will just be happy with 500GH and wait for a new firmware but thought I would share the results of my testing.
keep the cooling and got back to .93
do your boards have 8 or 4 VRMs? with 4 VRMs it will run hot but recover much better running .93
looks like I will be going back to .93. when I went to .95 on one miner, it dropped the watts from 770 to 470 with just a 30 Gh drop at first.. but now it dropped 20 more to 470Gh. I rather run it hot and back to 520Gh
also, when running .95 I added bertmod's firmware and found out that one of my dies is terrible. shows 24 cores off. cant tell when on .93 since that version of bertmod doesn't show cores
