Title: Claymore restart alone : WATCHDOG: GPU 1 hangs in OpenCL Post by: joboy84 on September 29, 2017, 02:21:03 PM Hello,
A few times per day, claymore (v.10) need to restart from alone and I don't understand why. Here is my setup : Quote Bios : Biostar TB250-BTC Ver. 6.x. GPU : Sapphire RX580 Nitro+ 8GB OS : win10 pro (fresh install) Driver : Win10-64Bit-Crimson-ReLive-Beta-Blockchain-Workloads-Aug23 Ram : 8Gb GPU-Z : Graphics Card : http://gpuz.techpowerup.com/17/09/29/2rc.png Sensor : http://gpuz.techpowerup.com/17/09/29/hwr.png Claymore settings : Quote -allpools 1 -ftime 10 -retrydelay 3 -tstop 85 -tt 65 -cclock 1150 -mclock 2200 -cvddc 850 -mvddc 850 Getting 0 rejected for ETH and approx 2% rejected on DCR. This are the infos from the logfile : Quote 15:25:57:738 ee8 em hbt: 0, dm hbt: 0, fm hbt: 78, 15:25:57:738 ee8 watchdog - thread 0 (gpu0), hb time 62 15:25:57:738 ee8 watchdog - thread 1 (gpu0), hb time 156 15:25:57:738 ee8 watchdog - thread 2 (gpu1), hb time 75296 15:25:57:754 ee8 WATCHDOG: GPU 1 hangs in OpenCL call, exit 15:25:57:754 ee8 watchdog - thread 3 (gpu1), hb time 75391 15:25:57:754 ee8 WATCHDOG: GPU 1 hangs in OpenCL call, exit 15:25:57:754 ee8 OC v7, Reset control for GPU 0, close miner right now if you want to use default control from Catalyst 15:25:57:926 ee8 OC v7, Reset control for GPU 1, close miner right now if you want to use default control from Catalyst 15:25:59:035 ee8 Restarting OK, exit... Sometimes by restarting the computer I get this message : Quote "Default Radeon WattMan settings have been restored due to unexpected system failure" What does it mean ? How can I solve this problem ?

Title: Re: Claymore restart alone : WATCHDOG: GPU 1 hangs in OpenCL Post by: joboy84 on September 29, 2017, 06:50:06 PM To be honest, I'm not very comfortable with OC/UV. This is all new for me.
I have searched for some tutorials but haven't found one where the whole thing is explained. I took a look on well known websites and copied their values. (BuriedOne and 1stminingrig) Buriedone has this conf in MSI afterburner : Quote Core Voltage : -96 Core Clock 1340 Memory clock 2250 But when I set up the same settings in MSI afterburner, my hasrates are very low (1-2 mh/s) From what I have understood and read, the core and memory voltage are used to make the cards consume less energy. The initial value is 1000. I don't really understand the value at Buriedone, using MSI afterburner. Is the equivalent for Claymore 1000 - 96 = 904? Where I'm lost is with the core clock and memory clock... 1stminingrig : Quote -cclock 1130 -mclock 2150 -cvddc 850 -mvddc 850 (900 mh/s decred 30 mh/s eth) They have a 512kb Bios and I have a 256kB. Don't know if this has a influence. And in some posts I saw this values : Quote -cclock 1150 -mclock 2250 -cvddc 850 -mvddc 850 -> 800 mh/s decred 26/27 mh/s eth -cclock 1130 -mclock 2200 -cvddc 850 -mvddc 850 -> 890 mh/s decred 29 mh/s eth -cclock 1200 -mclock 2200 -cvddc ? -mvddc ? (put 850) -> 910 mh/s decred 30.5 mh/s eth -cclock 1200 -mclock 2250 -cvddc ? -mvddc ? (put 850) -> 930 mh/s decred 31.5 mh/s eth Reminder : My values : Quote -cclock 1150 -mclock 2200 -cvddc 850 -mvddc 850 The 2 last ones are great but at this time I don't know if the cards will crash because they have higher cclock that mine. What do you think ? @xxcsu : You said that not too many cards can handle 2200 / 850 for mem clock. But in all of this exemples I found, they are at 2200+ in mem clock. I will try to put it at 2100. If I put 850 up, that would mean my card draw more kw ? If I put the cclock up, could this stabilise my card with 2200 mclock ? Thank you Title: Re: Claymore restart alone : WATCHDOG: GPU 1 hangs in OpenCL Post by: xxcsu on September 29, 2017, 07:59:08 PM Every cards overclocking potential is a little bit different ...
with gpuZ you can check the ASIC quality i would say if the asic quality is almost the same for all of your cards in the same rig , you can tune them together . If there is a big different with asic quality between your cards , and you want the max out from your cards , then you have tune your cards one by one for a long term stability . Big different with asic quality , i mean some of your cards have 90% ASIC quality , some under 70% Title: Re: Claymore restart alone : WATCHDOG: GPU 1 hangs in OpenCL Post by: joboy84 on September 30, 2017, 07:09:44 PM ok, just checked and for one card the ASIC quality is 71% (didn't put the second card online at this time)
I put only one card online for the moment for monitoring. Actually I undervolted at 920. The GPU memory clock is at 2200 (maybe I can get it a try a little higher) Power draw is at 135/140w (power meter), card is running at 61°C and I got less than 0.5% rejected shares for dcred. Hashrates : 31.15 mh/s Eth and 935 mh/s for decred. Not a single rejected share and no memory errors !! Seems to be a perfect match :) System is running stable since 4 hours. I will let this card running the whole night. Tomorrow I will put the other card online (alone) the whole day. Then, by night I will put both GPU's online again. What I don't understand is the core clock. What will it do if it's lower or highter ? I saw some people saying that the core clock doesn't really affect the values for ETH. But for some other algorithm higher values are better. Actually I have it at 1300. On the packaging of the cards they mentionned that in OC mode the card will be at 1411 Mhz... |
