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

[JuanHungLo]

Yeah, all my MBs are Asrock this is how they ID the GPUs:

[TechPark]

1 x sapphire r9 390 stock clock, stock bios, 63 degrees
~ 260 H/s

any advice how to raise that number?
Also I have no way to measure my wattage, can anyone tell me approx. consumption?

Is your electricity free? Who pays for it? Every flat/house/office have power meter, where power companies get the readings from- you can note the numbers and calculate the consumption - you only need an eye, a finger, a watch, a paper and a pencil. Surely you have all of it ))

do you have a monitor connected to gpu0

Yes. It goes black.
I plugged in a Kill A Watt meter, the PSU is 650 watts, and it's only drawing 350 from the wall mining zcash.

make sure that in power options you have set the hdd to never sleep

Need help with setting fan speed.

Here is the problem I am having.  If I use MSI Afterburner software to set fanspeed on all cards to 50% then it works fine.
However when I use start.bat with "-tt -50" the computer freezes and has to be manually reset.  I have 6 RX480 cards 8GB with different versions of the cards, some sapphire, some msi, some powercooler.

Any suggestions?

thanks!

I've found that it reboots and then the other card isn't detected...

check your riser

it has happen to me... just reboot and it should be fine.

Triple checked it, everything looks fine. Rebooting it works. But it still reboots unwanted.

sometimes when i touch my cards it reboots. I think the miner does it when something is not well connected. Did u try to put this in your config file?

"-r -1"  It will disable reboot mode

"-r -1"  It will disable reboot mode

It seems like turning the fan speed up was the most stable.
But i'll try -r -1.
Thanks again.

Edit: Crashed with -r -1 on normal settings.

Super stable with fan speed at 65%...

check the power cable and riser

you have a hardware problem

Install MSI Afterburner and set custom fan curves, I found a few of my gpu's were crashing also at anywhere from 75-80 above.. this should fix most of your crashes I think

Been stable for hours with my fan speed manually set.

You could try downclocking slightly, even perhaps 10 MHz.  Transistors work better at lower temps, but if temp is causing crash, it seems it is at the edge of stability anyway.   75-80 is slightly high for my liking long term for the longevity of cards, but should be fine as long as it is below 80C.  What are temps with fans 65%?

My shares are halved on flypool. Anyone knows the reason? On other pools had somebody experience the same?

Read recent posts... They increased share difficulty from 1000 to 2000.  So half the shares, but shares worth twice as much.  Reasoning is to reduce network usage and server resource usage.  If difficulty to low, hoards of tiny shares occur.  Many pools auto adjust difficulty based on your hashrate, but in the end it doesn't really matter how many shares you submit, just your hashes that the pool sees.  I mine on suprnova, 6 470s, the share diff is over 10,000, because pool auto adjusts, it starts at 272, flooding tiny shares, then it adjusts.

Thanks. Sorry, my hands was faster then my eyes. I have read the previous posts.

GPU 0: 53C
GPU 1: 48C

I was monitoring temps on the cards, and i think it might be the risers that are shutting off from heat? Because the cards never read above 70c.
