Claymore's ZCash/BTG AMD GPU Miner v12.6 (Windows/Linux)

[Claymore]

one question please:
since there is no polaris ASM kernel coming, everyone who has mixed rigs now (e.g. r9 fury + rx 470) is going to split them up to install driver 15.12 and run ASM kernel for their older gen cards. Is it worth it for r9 nano and r9 fury?
thanks!

i thought you need to run different driver versions anyways?

no, r9 fury and nano run fine together with rx 470 on my driver 16.11.5 ~ 1510h/s@580w
I guess not many here have mixed rigs then.

I could not get ASM to work with the 16.12.x drivers. I will try the 16.11.5 and hope that will fix the problem.
No i have to run 15.12 to get it working or not run the Nano in ASM mode.

When you start miner for Fury and it cannot apply asm, it displays a warning with info what drivers you need (15.12 or 16.3.2). Since both 15.12 and 16.3.2 does not support Polaris, you cannot enable asm for Fury and use Rx4xx cards on same rig. With asm you should see about 380-400H/s on Nano, without asm -15% or so.

Claymore,
After using parameter -di   тhe arrangement of cards is adjusted only for the speed. Temperature and percentage of fans remain disordered.

I have many rigs x6 r9 Fury each , and few rigs after some time, miner closed. I use -i 5 and Driver 15.12

claymore what does your miner set for default clocks

[espressodelisi]

v11.1 Linux version released.

Thank you.

[ghostfaceuk]

can anybody moving from v11.1 on windows to linux tell me if you see any difference in speed please.

[texv]

can anybody moving from v11.1 on windows to linux tell me if you see any difference in speed please.

For me [2 x (4 x Rx480 8GB)]
Windows version --> 1040-1020
Linux Version --> 980-990

[jeremyf327]

Has anyone tried the new 17.1.1 AMD drivers for RX 480's yet? I am not feeling brave.

[z0n0]

Claymore how old are you?

So a lowering of hash rate, what about temps and fan speeds?

Here is my linux miner output:
ZEC - Total Speed: 813.780 H/s, Total Shares: 464, Rejected: 3, Time: 00:48
ZEC: GPU0 171.829 H/s, GPU1 255.613 H/s, GPU2 119.854 H/s, GPU3 266.483 H/s


GPU0: Asus Radeon r9 280x : Faulty fan problem, that's why it's underclocked. Could not modify bios to undervolt. Could run 1050:1500 clocks if run single.
GPU1 and GPU3: Powercolor radeon r9 280x. Modified bios to undervolt. Good cards. Happy with them.
GPU2 : Asus radeon r9 270. Could not modfy bios to undervolt. thats why its underclocked.


and GPU clocks:

My PSU is a 80+ Bronze edition 1000W PSU. it's not enough if all the cards run full speed, so I need to underclock some of the cards.

Running ubuntu 14.04 with AMD 15.2 drivers.

Setting up and using windows is not easy so I do not use windows. I am too old to learn how to use windows. Linux is easy.

So a lowering of hash rate, what about temps and fan speeds?

For temps and fan speeds, I'm  using atitweak utility in linux. Setting the fans and clocks with it when I start the rig and monitoring the fans and temps with it too.

here is the set.sh on my rig to set fans and clocks:
-----------------
echo "setting clocks and fan speeds..."
#aticonfig --od-enable
.local/bin/atitweak --adapter=0 --set-engine-clock=850 --set-memory-clock=850 --performance-level=all --set-fan-speed=95
.local/bin/atitweak --adapter=1 --set-engine-clock=1050 --set-memory-clock=1500 --performance-level=all --set-fan-speed=80
.local/bin/atitweak --adapter=2 --set-engine-clock=850 --set-memory-clock=850 --performance-level=all --set-fan-speed=90
.local/bin/atitweak --adapter=3 --set-engine-clock=1050 --set-memory-clock=1500 --performance-level=all --set-fan-speed=85
#
echo "Setting finished. Now showing status..."
~/.local/bin/atitweak -s
-----------------


And using ~/.local/bin/atitweak -s
command, I can monitor temps.

Just now is available the Windows driver 17.1.1. Anybody tried it with the last version of Claymore Zcash?

I tried this one and nothing happened.. It same with other driver, there is no changes in speed, the only changes is the relive for gamers and you can't use bios modding..

I installed it and Claymore 11.1 works only a few minutes and blocks computer (a proof machine with a single RX 470 card) and is needed a hard reset.

Does mclock work on linux ?

[TimLev]

Interesting fact: after modification timings Gigabyte HD7950 gives stable ~330H/s with 1% rejected. (1190/1470) - Pic 1

If increase mem frequency up to 1500, GPU gives ~361 H/s. But about 15% of rejected. In log file appears strings of buffer overflow. - Pic 2

What does this buffer overflow mean ? Obviously, hashrate indexes is not very accurate ?

Anyone else have a 'GPU #0 returned incorrect data!' error? Happens on GPU #0, 1 of my 4 Saphhire R9 280xs, after about 6 hours of mining. It's always the same GPU returning the error, while the others are fine.

Are you overclocking ?

Had such happiness with one card. In my case, solution was a significant drop in temperature. Probably some radio elements lost characteristics with age and at high temperature becomes unstable.
