I am setting Voltage Offset to -125mv.
I am doing custom roms for any gpu but its paid service.

Yes. There is no other way in linux.

The spinning up was too slow.
Anyway i will improve this script so it do burst 100% fan speed when temp is >85 C
Ok. Thx for quick report.
I have undervolted gpus so my temps are much lower.

I made V1027 update, wait until it updates (max 5 min)

I made bigger steps.
Tell me is is better now ?

it will update itself

send me PM  with your email and rig number

RX oesnt support 200 series.

UPDATE V1026
- RX OS auto fan controll set to 76 C.
Tomorrow i will try to release option in dashboard so you could set your own target temperature.
I will also try tomorrow make R OS auto fan controll.

Try changing USB options in motherboard BIOS.
I could uplaod new image but later today/tomorrow.
I think it is bios option becasue most people dont have this problem.

Can you try on different drive ? perhaps pendrive 8 GB ?

Try without Memory OC. Helped me.


Problem with speed is random and its a kernel bug.
I am already working on new linux kernel 4.9 which generates faster rates and propobly fixes overclocking bug.
I need to test it and  i think about upgrading it partially.


If you have those errors then something is wrong with this miner.
Updates v1013-2015 didnt mess with linux system itself, there were only miner updates and few other fixes.


Anyway here are variables you asked for:
Kernel 4.8.3
AMDGPU 16.30
Ubuntu server 16.04


I have working FAN speed script. propobly i will integrate today/tomorrow I will send email before i will make this update.

download this from website,r it will auto update to newest !
its always do

You can
Or just send me donation BTC: 1ERRVbvV23h51ScH73nQr6TDmaieKNuuVD
thx

Miner is working pretty nice !
Anyway maximizing CORE speed (MHz) finally doest better effect !
All my R9 380 have like 90 sol with unmodded bios (without tighter timings) so even more with timings and >1500 MHz  in memory ! i suppose 110 sol.s
while RX470 have 120 sol.s
Confirmed in coinmine.pl zec pool !.
Works stable and no hanging for now.

TIP: zcash mining requires lowering memory speed IF YOU HAVE HANGings

Yeah no problem, but i have security issues when implementing so quick not known miners !
I think about making root accound secure again so changing password.
So when i implement miner, it even can have virus or malware but it wont do a thing to your system.
And now when i released root password for all - it  might be a problem, i must tink about tis.
Is anybody have an idea tell me

This new miner "OptiminerZcash" is nice
I turned 1300 MH/s in ethereum to 5300 H/s in Zcash in this new miner (confirmed im pool)
60% are R9 380 and 40% are RX470

UPDATE v1025
- added another zcash miner: https://github.com/Optiminer/OptiminerZcash
it is pretty fast
110 Sol/s on RX470
92 sol/s on R9 380

interesting, i will look at this tomorrow.

there is no dedicated button but it will be also soon as reboot
Anyway you can do that by going to rig Overclocking settings, put some values there and SAVE
each SAVE closes miner, sets OC and starts miner agian

Thx, kind words are always welcome
Fan reculation is near and soon it will be implemented.
I have script that works under RX OS and testing it right now.
It will be adjusting fan speed to target temperature so you could enter like 50-80 C.
Anyway setting fan to 100% isnt good becasue it could make fan wearout little faster than it sould be.

Did you tried Overclocking to set like 900/1500 ?
Then you need to change timings in bios rom of the card to make it even more faster.


I had those only when rig is too much overclocked.
Anyway i think that silenarmy is still unstable and claymore did much better work.
But becasue of "angry" people we wont receive anymore linux newer version of miner from claymore so thx them for that.

Yep i will refresh tutorial on youtube becasue its little old that one.


The problem isnt in intensity.
Claymore wont release newer versions of Zcash miner for linux !. Newest version for linux 1.1 and for windows 4.0
Anyway if you want mine zcash try new silentarmy-v4 miner - it has 80h/s on rx470

UPDATE v1024
- new silentarmy v5 ZCASH miner ( rx480 has 80sol/s)

And what do you mean by that ?
Do you want to mine in minergate pool ?
If yes then got o options, hoose claymore eth CUSTOM and enter your pool, user and password info.
