Hello,
I have a problem mining with AMD Vega 64 on Windows 10 PRO (RX580 Works fine)

[2017-10-28 18:50:06.664] [info] [GPU4] Device info: {"id": "1/4" "name": "gfx900" "platform": "AMD" "driver": "2442.9 (PAL,HSAIL)"}
[2017-10-28 18:50:06.680] [error] Build Status: -2
[2017-10-28 18:50:06.682] [error] Build Log:
Error: AMD HSA Code Object loading failed.

Does anyone use single rx vega 64? what are the hashrate values? how to blockchain driver for btg mining? I once tried to see 450 sol/s with blockchain driver (hbm2 1085 mhz, gpu -10%) worth less?

[fapar]

Is the hash rate reported on the command line accurate or do I need to wait to see what the pool says after (say) 30 mins? I'm tweaking my settings and overclocking, but I'm not sure what to trust.

The trust should hashrate which shows the miner. Pool can display hashrate different from that of the miner in larger or smaller at different times.
The main thing is the number of received shares.

Having trouble getting this up and running for AMD. I'm a newbie to mining so I'm probably doing something very simple and dumb.
I don't want to spam this threads with questions, but if anyone is available to PM me so I can bounce some questions off you, I would SUPER appreciate it. Thanks much and good luck to everyone mining.

I always get this problem whenever i start to mine, been trying different pools but i still get the same error can anybody tell me how to fix this.
I dont know what "OpenCL error" this is my first time mining.

I'm looking at your Video Card.... and I see it has 887 mb vram and 2 compute units.. Dude
you can't even use that to mine with... Get a AMD RX 480 or the new VEGA cards.

Claymore is tested on our Bitcoin Gold Mining Pool: https://gpool.guru. Have fun!

Thanks for the tip, i was using this PC for 2 years now and never got the chance to upgrade it.
Maybe i should buy a higher specs PC before i will continue bothering to mine bitcoingold.

anyone who owna  R9 380 can tell me what is the hashrate at 1050/1700?

I run 8xSapphire R9380 4gb core 1000 mem 1625 with 100mv undervolt @ 228h/s each all day long

ps. 720h/s on cryptonight and 22.5 Mh/s on ethash.
windows 10 x64 8gb Ram and latest blockchain drivers.

Does anyone here know how to get past the opencl error 0 #101 issues? I'm running a pair of older 6970s, and with every version so far I've had these errors pop up, one for each gpu. Then the miner proceeds to sit there and do nothing at all, or BSOD my system.

This is so odd!! This worked for like three days then all of a sudden I start getting these same OpenCL errors!!  I have a 4mb rx480 and an R9 390 BOTH of which were able to run on previous versions as well!  If anyone has any parameters that might work, let a Ninja know!?  Thanks in advance!

@Claymore: Can you support mining Zero coin with equihash with  parameters: N=192, K=7

[amber46]

I had to run two miners - three cards each.
Earlier I pointed to each of the miners keys -di 012 and -di 345 so in one system worked two miners.
If you delete the keys -di and -gmap - how can you now run the miner only for a certain number of cards?

[Nightlander]

I'd like to see -minspeed option implemented with claymore's zcash miner as well, it has been most helpful with his ethereum miner. I've noticed quite a few radeon drivers have tendency to randomize new core clocks pretty much every time display goes to sleep/wakes up, clocks can go either to idle or something in between idle and base. As that lowers the hashrate, minspeed detects it and restarts miner with proper clocks.

Same has happened with 390 and 570, countless of different radeon driver versions... Basically it's just easier to battle it out than try to find working drivers, so I've just used ethman to restart zcash miner but -minspeed would just make things super simple.

Edit: To specify think this only affects windows 10 and it's various versions, haven't noticed same thing would happen with 7.

Just reduce the clock frequency of GPU0

Well im really new to mining and doing program and stuff,so can you tell me how should i do it since i dont know what is the frequency of GPU0 and how to reduce it because im afraid if i did something wrong it might ruine my PC.
I would really appreciate any help to mine bitcoingold.

Use MSI Afterburner to change the card(s) core/memory frequency.
Some more information on your setup would help us fault find the problem, such as what type, and how many, cards you are using, which OS, etc.

EDIT: Just noticed your card has 887MB of memory, it does not have enough vRAM it will never work. Is it a laptop you are doing this on as it looks like you have an HD7520G video card (or similar) ?

This miner only supports GCN cards. Older VLIW cards like HD6XXX series and some HD7XXX cards are not supported.
Check the AMD GPU list on wikipedia and you can find which models are GCN.

@CLAYMORE, could you decrease the devfee? still here and stayed at 90 seconds, and not all pools support SSL

[halker2010]

my 480 rig keeps crashing with rejected shares, any idea what can i do to fix this ?

Check the driver, reduce the frequecy.
