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

I think that this new version is not so stable than the others. I have some rigs falling after hours of working.
I do not know why the miner falls., I did not make any changes, only the version.
Thanks

In my case  it is very stable, I have no problem with v9.2. Maybe you should check the PS-u.

I have not change the psu, is a EVGA 850 with 3 RX-480 is ok. Now i will try to reduce intensity to 4 to see what happens. Thanks

Uhmm, 850w it should be more than acceptable for 3 RX-480 ( I'm running 6 R9 380 cards on 1250 W PSU).
 What version of driver do you use?

I have one r9 270 and three r9 280x cards with 1000W PSU. PSU is on the limit.
before this miner, it was working fine. but with this version, with the optimisations, the power draw increased so I had crashes. Now I downclocked soma of the cards and it runs fine. I know I need bigger PSU but I do not want to spend on that now. So, downclock and lose some hashrate is ok for me.

Hi guys, help to understand the Claymore's Remote manager.
Adding a miner I need to fill 2 fields
1) Target ZCash hashrate (MH/s)
2) Target - hashrate (MH/s)
What is the difference?
I have 6*RX480, total approx. 1450H/s=1.45Mh/s
I've discovered that it is not colored if I set
1) 1.4 or 1.45
2) 0
Thanks.

FINALLY a LINUX build!!!!!  Thank you Claymore!  Thank you, Thank you, Thank you!  

I have it up and running on a Linux rig now and a very nice improvement over my Silent Army miner.  The was so sorely needed.  ZEC mining was a weak spot because I couldn't get the hash rates out of my Linux rigs.  This is wonderful news.  So far it looks good!

UPDATE: I may have spoke too soon... Just got a watchdog and having to reboot a miner...

i have w-10, driver 16.5, Asrock H97 and unpowered risers.

Make sure you use stock clocks for first tests.
Currently I can only confirm issue with gpu-pro drivers that causes a lot of messages to syslog (and therefore high CPU load on multi-GPU systems), I'm working on it.

I had a setback installing Ubuntu in dual boot with Windows. Ended up with a crashed system last night due to some unexpected trouble so I went back to windows and will give it another attempt later on...

Anyway, does anyone know what the performance is of a HD7950 with Claymore with Ubuntu?

[mohnori]

v9.2:

- improved speed for some cards up to 7% (depends on card model). About 330H/s on stock 390X, 235H/s on stock RX480, 300H/x on stock Nano.
- several bug fixes and minor improvements.

Thanks. I'm getting about 245H/s ~ on Msi Rx480 4Gb with modded bios.

Can you please share the modded Bios for Msi Rx480 4Gb?

How much is obtained on 470 with modded bios?

On hd7950 getting ~180 H/s ( stock settings)

Yeah! I thought I was the only one getting these.  If you disable rsyslog, and you disable printk from writing to your console screens, then CPU usage will not impact mining speed anymore.

Here are the steps I took to allow me to use this miner

# check your current printk settings.  
$ cat /proc/sys/kernel/printk

# set CUR printk to 0 (emergency) or 1 (alert) to suppress (crit/err/warn/info)
$ sudo dmesg -n 1

# you can make these changes permanent via sysctl
$ sudo echo 'kernel.printk = "1 4 1 7"' >> /etc/sysctl.conf

# you can set them in real-time with
$ sudo sysctl -w kernel.printk="1 4 1 7"

# prevent it from filling up your syslog
$ sudo service rsyslog stop

Or just disable syslog output in /etc/rsyslog.d/50-default.conf

# comment or change your log types
# *.*;auth,authpriv.none          -/var/log/syslog

# then restart rsyslog if you comment out the above
$ sudo service rsyslog restart

around 215-225 depending on your exact settings

850w is fine for 3x 480. I have rig with cooler master v1000 to 1x 280x , 2x 480 and 1x 390 and second PSU 550w for 280x + 7870 = 850-870w for first PSU + 330-350w for second PSU
Have other rig with again cooler master v1000 for 4x 480 and 2x 280x = 870w for 6 GPU

# comment or change your log types
# *.*;auth,authpriv.none          -/var/log/syslog

# then restart rsyslog if you comment out the above
$ sudo service rsyslog restart

Forgot about kern.log, as gpu faults also print there..

# kern.*                                -/var/log/kern.log
# *.*;auth,authpriv.none          -/var/log/syslog

Easier to just stop rsyslogd on boot, or change "on start" in /etc/init/rsyslogd.conf

9.2 isn't stable like old releases for all systems. Mostly it fails in 6 X vga rigs. I updated from 9.0 to 9.2 and I always got gpu0 hangs.

Strange, for me it is more stable than 9.1 or 9.0 ( 6x 480s - modified for ETH but @ 1200/1950 )...

[eduardo_rc]

Anybody who's tried both the Linux and Windows builds can say which one is faster?

I have RX 480s and RX 470s.
