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

[orbital_station1]

Hello, i have a problem.
"Miner thread hangs, need to restart Miner"
I keep getting this error after about a hour of mining, not sure why I keep getting it. The miner itself freezes at a certain time period and only hitting a keyboard button will bring up the error and restart the miner.

Swap risers around, then see if any of them is faulty.
It could also mean too high clock/mem oc.

Ofc before any of that do obligatory driver reinstall with DDU.

If none of that fails, try heavy underclock of the card in question. Then increase the clock bit by bit.
I had that message showing, and after a couple of hours of testing I found out my GPU was faulty. It was stable only when I downclocked heavily.
My r9 390x has stock clock of 1080, but I had to downclock to 990 to get any kind of stability. Ended up RMA-ing it, since it crashed every 5 minutes at stock speeds.

Hope this helps.

Claymore, any news on Zcash support for AMD RX460 like you did on Ethereum side?

The message "GPU #x returned wrong data" is mostly due to bad ram overclock or very high core clock?

Yes. Just reduce the frequency.

ram or core frequency?

Yep, I second this. Uninstall your drivers, and be sure to install 16.12.2. I've found it runs very stable. And as Orbital said, lower clocks for stability are better than trying to squeeze ever last sol/s out of the card with bad stability.

I've found for RX 480's, I do about 1200mhz core, 2075mhz clock, -42mv undervolt, and at -i 4 in Claymore. Seems to give me about 280-290 sol/s.

RX 470, try something like 1200mhz core, 1675 memory, and again, try undervolting a bit.

I've also found that issues with power supply lead to system freezing, hanging, etc. Swapped out my old Rosewill Photon 1050 on my four card rig of RX480's, to just a crappy Sentey Metal Blade 850m. Works like a charm and very rarely hangs up.

Checking risers and whatnot are an option, but much harder to really diagnose and narrow down. I'd recommend the aforementioned fixes first before doing that. Good luck!

That is try and error. Mostly RAM.

Yes I'm working on it.

Hello

Im mining for few weeks now
Every thing is running fine but my earnigs where the first 30 houres.  0.004 at least every round
And now it is arround 0.002

Im mining on i=7  this is the only thing what i got in de config file also
Got 9x r9 290 few of them are 290x

I am mining zcash on supernova

Can some one please help me

I'm new to mining but am having a tiny issue so wanted to see if I was doing something wrong.

I have 3 GPU's in my system and all of them are stock RX 470's.  While running it shows GPU 0, 1, and 2 all working fine.  The odd thing is when it shows the temperatures and fan speeds it will only show this for GPU 0 and GPU 1.  I have tried using -gmap 012 and also -gmap 210 and it still only shows 2 of the GPU's.  See below:

From reading the documentation this should be showing all three GPU temps and fan speeds, so I wanted to ask what I am doing wrong that is preventing this from happening.

Thanks in advance for the help!

try a dummy plug.

Check if crossfire is enabled. If yes, disable it...

I had something similar happen (only 1 temp was showing for three cards) and it turned out that Windows updated the recommended driver the latest. I think its Crimson 15.12 that is recommended.

I've 4G R9 380 MSI Gaming and 2Gb R9 380 MSI Gaming. So 2Gb GPU is about 220-230 Sol/s, but 4Gb GPU is only 200-210, overclocink settings are the same, tried different intencities. Any ideas why less RAM cards give more sols?

[Dukebit]

HI Guys

please assist if you don't mind, I'm running two gpu's in my machine, but for some reason the hashrate of the gpu in the second PCIe16 slot is very low?

if tried switching the gpu's but the outcome is the same the gpu in the second PCIe slot performs very poorly.

The well performing gpu run in PCIe x 16 3.0@16 2.0 while the under performer is running in PCIe x 16 3.0@ 4( instead of 16) 1.1.

what must I do to get the hashrate up ( the underperforming gpu currently doing a quarter of what is actually can).

hope some will be able to help.

thank you

[fr4nkthetank]

You my need a dummy plug.  try plugging a monitor in it, and off/on.  see if that helps, then remove the monitor if its good.  the 4mhs bug is well documented on this forum/google, you should be able to fix it without problems.

[Dukebit]

HI I managed to fix it by plugging in an additional screen.

Thank you for the advise!!!!

I'm getting a combined hashrate of 33.6 H/s on Eth classic, joined the nanopool.

Is this a good hashrate for the R9 280x and RX570 combined? Using Claymore's miner.

that is strange, on my ring it s actually the opposite, the gpu with screen plug hash slower

33 for 2 gpu is actualy very low (don't know hastrate of 280's but should be 20+?  same for 570 and 27-28 if you have a moded bios
so you should have at lease 41-42 with stock clocks

don't know ram speed ?   but i have all 2G   sapphire & xfx are the fastest  and asus the slowest even if oc to same speed as sapphire&xfx, asus memory are slower
