Ok, I have been slowly reading back through this thread... It reads like a soap opera!  LOL

On the GenTarkin firmware I had a question.  For miners that have weak or non-hashing dies.  Does the firmware try to move the MHZ setting down on those dies to try and bring those dies back to life?  Or do we simply set the firmware at the starting point where we want to tune it and it mainly focuses on the leanest voltages at a given setting?   The rig I just bought I know has some weak or dead dies that I am hoping to bring back to life or get a few extra MH out of it.  I am waiting on this rig to arrive in the mail this week.  I have read what others have posted on how to get this tuned manually, but I was curious if the firmware is already doing some of this work. 

Also on the energy saver mode do you have a watts per hash calculation?  Maybe an option to choose a energy profile of "ultra conservative", "conservative", "passive-aggressive!" mode that calculates the best hash per watt consumed and tunes it down to that level based on the level of performance the user wants?   For example I saw the post earlier from Lightfoot regarding the heat and power consumption jump going from 225mhz up to 275mhz.  So I figured if the sweet spot for these dies for stable and cool operation is in the 225mhz range then it would seem that it would be possible to calculate energy profiles based on hash rates, temps, and power consumed.  If your already doing all of that please forgive my ignorance.  It is very appealing to me to be able to run this rig cool and stable... and save energy in the process while getting the best performance possible from the rig.  I have already ordered the parts and tools to do some of the mods to the heatsink, and the dcdc cooling.  I am hoping that by getting some fresh thermal paste, and getting better heat sinks on the dcdc converters that this will help with the rig I bought.  I wasn't able to tell from the thread if the investment in other fans would give me much of a benefit.  I am curious what others are doing in regards to the fans.  My rig is a batch 1. 

I think there is a copy of the GenTarkin firmware on this rig that I bought, but I have no idea if this is purchased copy or what the story is yet.  I will be reaching out once the rig is here and getting this license sorted out and get the latest copy of the GenTarkin masterpiece! :-)   

I appreciate all that you guys are doing and sharing on this thread.  It is very helpful!  Thanks!



Hi, I think I was bidding on that Titan you bought  Smiley

this is what I would do, -- replace the thermal paste, clean the heatsink & pcb with some 99.9% isopropyl alcohol & brush, blow it out real good, and replace the fans with noctura highspeed fans , then let them run for awhile. With the noctura fans & a clean heat sink you may not need any more cooling (dcdc heatsinks)
