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

[espressodelisi]

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

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.

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

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 ?

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 ?

[a1unicorn]

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.

[a1unicorn]

Are you overclocking ?

No, using stock cards.

What temps did you have before/after? My GPUs are hashing at around 68-74 C.

v11.1 Linux version released.

Thank you.

Thanks Claymore, keep up the good work 😀

What voltage do you have to overvolt to get it stable at 1190 Mhz core?

what are your command line in the miner &?

Usually this occurs due to the intensity.

I'm just running the default settings, with just my mining pool and account/pass in the command line.

would love to know that too. my fully oc msi 7950 only gives me 260, those numbers are what i get with a 290x modded as 390x

use atitweak utility on linux.

I do not think it's good for miner to set clocks. its not its job. miner needs to mine best and gpu setting utility needs to set clocks and fans best. its unix.

Your GPU tries to tell you 'Help, help! Please don't kill meee! I am too young to dieee', but you do not listen.

Dear all
i have some  290x cards i am looking for best C/memory setting to give max hashrate in zec

i try 1050/1450  and result is 330h/s  in some cards but do nothing in r9 290x gigabyte windforce   - max is still  277h/s

also i have some 280x - 285x  - 380x nitro cards i want to know also the best setting for it

i use win7,,8, and 10 in  different rigs with 16.9.2 - 16.8.2 drivers  v11.1 claymore
