Claymore's Dual Ethereum AMD+NVIDIA GPU Miner v15.0 (Windows/Linux)

[scryptr]

PSU/RISER PROBLEM LIKELY--

I agree with Klassje.  It is likely that a riser is bad.  Old, skinny-version risers get really hot and sometimes melt with dual-mining, and even new risers go bad.  It is interesting to note that if the problem occurs, the "511C" figure is common.  I have had the same readout; the card was good but the riser was bad.
I would stop the rig and change risers before mining again.      --scryptr

And which risers are better to take?
I have a 6 version with a black wire....like these ones: https://ru.aliexpress.com/store/product/Black-0-6M-PCI-Express-PCI-E-1X-to-16X-Riser-Card-Adapter-PCIE-Extender-with/1826735_32789606816.html?spm=a2g0v.12010608.0.0.81bf1c12u9nXF

RISERS ARE EVIL CREATURES--

Your riser looks ok, but there are many variations that look the same.  I use a riser that is v006c or v007, depending on the manufacturer or the distributor.  It has a PCIe electrical connector rather than a molex.  I started changing out all my old, skinny risers when I noticed the thin power connectors melting.

I cannot give much advice for which riser, but switching out a riser will often solve the problem.  The PCIe connector is more sturdy, thicker, and less subject to heat damage than a thin molex, once standard for floppy drives. The larger molex on your riser is often difficult to connect because the pins push out-of-position.
 
Keep spare risers handy, find a good source.  I am in the USA and shop Amazon.  MintCell is an Amazon retailer that has good risers, but even new ones fail.

Good Luck!       --scryptr

Is there an other possibity for fixing the DAG epoch issues for Ethereum mining than the aug 23 blockchain driver?
I ask this because in my side, i have not found any way to run the blockchain driver with stability on my rig 8 gpu's under Windows 10, therefore i see the drop hashrate and i can do nothing to solve this issue at this day.

Thanks in advance for help.

I dont understand the bios modding. What am I to be changing on my Polaris cards I am only get roughly 20mh/s out of them on ETH.

When i load the bios following instructions, they say change timing, the timings are all kinds of crazy hex numbers.

I also get an error about my bois being too small

You cannot use GPU-Z to save the BIOS as it only saves half of modern bioses. You must use ati flash to save the bios. You are copying the memory straps from either 1500 (hynix, micron and elpida) or 1750 (samsung) and pasting it to all memory straps higher than it, such as 1650, 1700, etc up to 2000 or higher. This makes the memory run with tighter memory settings so hashes more. But it can also make the card unstable and/or crash.

How do I tell memory brand... also I am using ATI flash to pull them. They appear to already read as 2000 as thier default memory speed?

When you start GPU-Z, it reports the memory brand. Also use the following article for BIOS flashing as it tells you the correct Polaris BIOS editor version to use in order to get rid of the craxy hex numbers you're seeing:

Can't undervolt/overclock with AMD Blockchain driver even with v10.0 I know we can do that with Wattman, but I don't want. And with Afterburner we can't undervolt memory and it's limited.
Is it planned in next update ? Thanks

Okay all m y cards are hynix so I can OC them a bit? My screen for timing looks nothing like his.

Okay all m y cards are hynix so I can OC them a bit? My screen for timing looks nothing like his.

I find 2050 is a good number for Hynix, I have had some success at 2100 but not long term stable.
Also for Hybix copy memory straps from 1500 into all the higher number ie 1625 1750 2000 etx.
I switch away from etherium for now as all my rigs use windows 7 and I am not keen on full reinstalls just cause of the half job AMD did on their block chain drivers.
So I am mining anoher Ethash coin along with LBRY
Getting 28.6 ethash and 74 LBRY on 570's Hynix
            29.7 ethash and 79 LBRY on 580's Hynix
            13.2 ethash and 32 LBRY on 550's Micron ( can only get to 1950-2000 stable)

Seems wrong version of PBE, you need to find one which display the timings properly... did you try the one in the article I've sent earlier?
...and always 'Run As admin'....

Yea Ia m using Polaris Bios editor 1.4 and atiwinflash

Wow,  Vega 64 - 43.5MH/s at 130W: http://wccftech.com/amd-rx-vega-64-pushed-43-5mhs-130w-mining-ethereum-eclipsing-polaris-efficiency-factor-2x/  Really???

"Our test bed idles at 138 watts and the entire system consumes an average of about ~385 watts under load while mining."  Big difference than that clickbait 130w.

OK, so this screens is a fake? https://imgur.com/a/1GgvR

Use the latest v1.6. You definitely don't need to run PBE as an administrator. Atiwinflash does.

Sorry for this a bit noob question but ... is DAG size still issue with AMD cards or did new mining driver solved this? thx

[SUKY2217]

hellow guys i more new to this and been tryng to run claymore v10 and i think im fail all the set up . i wana let mine XmR on supernova ssl://xmr-eu.suprnova.cc:5221

and me bat for the miner  looks like this

 NsGpuCNMiner.exe -o ssl://xmr-eu.suprnova.cc:5221 -u ACSuRdHp3fEMSWahh1Yn7faTW5BRvXaejHsj3iCJHYGRfUbvUS6qno6H4JqLnHzStwWEZa3oFkVwE1Y FUvqePCFYH7XqVdQkim2BFTJJod.xxxxx/xxxxxxxx -p x

can sombody help me to set up right thxx

to many noobs vega reviewrs, vega run 43,5mhs at 170w, on 17.8.2 driver with 960/1100 at -24% power limit

Is there any change for r9 290/390 GPUs?   ty for any info...

Is there a newer version of atiwinflash? mine really only lets me see 3 cards at a time.


never mind - use CLI is so much better. Ty ty.

[ozzy1926]

Same setting but v10  is not stable as v9.8

And no FAKE that high hashrate iff you look closely they get it on Ubiq NOT ether haha
So DAG file much smaller only way to get higher hashrate so far

[fmz89]

testing on ETC with same hashrate, vega itsnt same as RX, similiar with furyx didnt mater what coin is
in the futere looks like rx and other card will sell on ebay soon after vega masive production, oh boy dont worry if you already bought ton  of rx 400/500 or nvidia pascal card which is very expensive with longer ROI
