Topic: Claymore's Dual Ethereum AMD+NVIDIA GPU Miner v15.0 (Windows/Linux) - page 617. (Read 6590565 times)

There appears to be two versions of Polaris Bios Editor V1.6 ?
The one from https://github.com/jaschaknack/PolarisBiosEditor has the "One Click Timing Patch" option and the other has the option "Apply Ubermix 3.1 Samsung Timings" - both say they they are version 1.6.
I've been using the "Ubermix" version with no problems - can't remember where I downloaded it from.

Does anynoe know what the difference between the 'One Click' and the 'Ubermix' timing are ?
I'll have a go myself and see if I can spot anything - I may be some time figuring this out.

with the updated version of Polaris Bios Editor using the supplied timings instead of copying the 1500 timings I get roughly 0.2 - 0.4mh more per card

It should be higher. Try increasing the -ethi to 8. My eight card mixed RX 570/570 4GB/8GB rig is getting 28.5 to almost 30 MH/s dual mining UBQ.



If you are on Windows mining ETH make sure you have the blockchain drivers with the epoch Dag fix patch.

Nothing new for 280x / 290 / 290x?

Need help from Ubuntu experts

Hi!  I need some help from Ubuntu experts.  I set up a test rig using the Sapphire Nitro+ RX580 on Windows 10, using Afterburner to do some mild overclocking - Stable on Claymore 9.8 with customised fan profile.  I flashed the bios with the Hynix timing straps and I am getting around 24mhs, which is not bad, but not great either.   It is stable.

However, when I tried set up an Ubuntu environment (16.04), I can get it stable at standard clock rates - however it crashes when I raised the clock rate using the flashed bios with the overclocked memory that works well in windows.   The fan seems to be kicking in very late, and I was getting 76 degrees at 25% fan. 

Here's a list of my questions that I hope the Ubuntu/Claymore experts can help with as I am a beginner in Ubuntu:

1.  I tried using the -tt and -fanmin command in Claymore.  I get the error message "Failed to set new fan speed, check if miner has root access!".   How do I set the miner to have root access?   Right now, I am starting the miner with the command in terminal "./mine.sh", where mine.sh is the claymore start file. 

2.  I am getting a list of error messages off the standard environment variables in Claymore.  As below:

"alvin@cryptominer-one:~/Desktop/Claymore98$ ./mine.sh
./mine.sh: line 1: export: `0': not a valid identifier
./mine.sh: line 2: export: `100': not a valid identifier
./mine.sh: line 3: export: `1': not a valid identifier
./mine.sh: line 4: export: `100': not a valid identifier
./mine.sh: line 5: export: `100': not a valid identifier?

Appreciate some insights into the above.

3.  -mclock 2100 doesn't seem to have any impact on the hash rate (standard is 2000).   Am I using it correctly?

4.  How do I monitor GPU status in Ubuntu?  Aticonfig doesn't seem to work.

Thanks!
