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

[Claymore]

Hi, Claymore!
Will drop you in the near future a new version of your miner ZCash?
Can a little more detail about the stability of version 10?
Thanks  

New version will be available in a few days.
I don't see any problems related to stability in v9.1, so if it does not work for you it's possible that new version will not work too.

guys, need some advice with a odd problem on 2 rigs pointed to dwarf port 3333....

Rig nr.1 has much more rejects as the another one, it has up to 0,80% of rejects the second one has 0,10-0,20%  How is this possible?  (before the dwarfpool problem 2-3 days ago on EU server it was more or less the same amount of rejected 0,8-0,15%)


Rig nr.2 has problem to conect to port with Dev fee... is always attempt to connect but it fails "DevFee: ZEC: Job Timeout, disconnect, retry in 20 sec..." and this like 5x-9x before it finally beginns..

Is the problem by mee or the pool?


Many thanks in advanced for any reply.

  Hi!
On the contrary it is the rules that all works peschat do not understand!

[_ZET_]

Can we expect v. 10.0 ?

NVDIA's miner did huge progress. Worry they will be better for ZCASH mining. Lots of AMD users may be upset.


Waiting for positive response.

You can tell what will be improved in the next version? I'm waiting for the new version. Thank you

i have 3 asus r9 fury
and i can not running
claymore

why that happen

run for 5 minutes
then 1 card send error at system
then after 1 minutes one card stop working
and after 3 minutes

the open cl doe not work
and windows 10 restart

why that happeennnnnnnnn

Lower miner intensity, revert to stock rom, fix drivers etc.

It's likely your drivers. I was able to run Furys with 16.xx drivers until the v9.0 release. Now I have to use 15.12 or I get errors on opencl calls.

I had random reboots on some of my rigs after updating to CZM 9.0/9.1. Try to underclock and undervolt your cards a little (for example I use my 470 4GB with 1200Mhz GPU clock + 1000mV, 1750Mhz memory clock + 950mV, and -5 for voltage offset in WattTool). That solved me the stability issue.

Thanks for the idea, but i have 6xRX480 and i feed with PSU SEASONIC 1000W Platinum! There should not PSU be a problem, but I do not know?

1000W is really "narrow" for 6*RX480 cards with stock settings.

I have 6*RX470 with Enermax MAXREVO 1600W in the "unstable" rig. So It can be power problem (I mean the power spikes: you can read about that spikes in the previously posts when v9.0 arrived). I have more rigs with exactly the same hardver and I didn't experience stability issues. Since I did this little underclock/undervolt I also have no problems with this rig. (and the hashrate isn't lower)

So.. just a tip. Try to undervolt and underclock the cards a bit. Especially because 1000W is too short for 6*480.

You most certainly have a power problem.

I can replace with Seasonic SS-1250W XM2! This will improve the situation there?
Card settings are -48mV / core 1175MHz/mem 1200MHz?

[jelin1984]

 I have to use 15.12

howi must  install these drives at windows 10
because when i go to install it

the drivers tell me that open cl does not install

is any custom details for install these drivers?

1250w PSU should make all your problems go away. Also, you can push -100 mV on most RX480's

It's likely your drivers. I was able to run Furys with 16.xx drivers until the v9.0 release. Now I have to use 15.12 or I get errors on opencl calls.

I have 6 Fury's running with Win 10 V9.1 16.6 -75mv 900/550 @ 285s/s each @ 845Watts to the wall

I could go to -98mv but one of the cards doesn't like it and I don't have to time to figure out what one is the issue. It does draw a bit more power but the hash rate is also increased so I'm not that worried about it.

If I were you I would use DDU, uninstall the drivers and reinstall 15.12 drivers only.

what is DDU?

ALSO HOW I CAN INSTALL 15.12
because i can not install these version of drivers?

[adly3000]

Sorry for the off topic...
In case of 6x480:
can you please explain how you connect the evga G2 molex to the raisers?
are you connecting the molex which is in series to the usb raisers direct!!
If yes then I only see 5 molex (on two cables 3x1 & 2x1) while you need 6, or you use one sata as the 6th!!!
any help would be appreciated.

DDU

15.12 Drivers
http://www.guru3d.com/files-details/amd-radeon-software-crimson-15-12-driver-download.html

When asked what you want to install, make sure the only thing is checked is the drivers( I believe its the first box and there is one you can't uncheck)

I would also remove the profiles in Afterburner. C:/~Program Files/Atiafterbuner/profiles (something liek that)

Reboot

Use 2x 850w power supplies = 1700w, then you should not have any power problems.
