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

[SummersideGuy]

These days, does mining ethereum need >2GB vram or just 2GB Vram?

greater then 2GB

The latest version of Polaris Bios Editor v1.6 from jaschaknack makes it simple to apply the right performance timings for your card. With the 'One click timing patch' option it will apply the bundled performance strap to the correct timings. I tried it with several brands of RX 570/580with Hynix, Elpidia and Samsung memory and they all now get 29 M/s+ stable. Much better than randomly copying timings from the diffrent straps. Some cards like the Sapphire Nitro+ have two diffrent sets of straps from diffrent brands of memory and PBE will corretly detect and apply the right strap to the right timing. Great update!

Remember to save the Bios after it's patched

I get error 43 after flashing straps with atiwinflash. Is it true that I need pixel patcher to solve the bios signature check?

[YIz]

I'll update after I get my new shiny Vega. Hopefully, it improves the hashrate a bit.

[mengy]

anyone having issues with Eth Mining + Sia (using rx vega)

v9.8 works perfect, get around 36 Mhs and 900 Mh/s Sia.

v10 works with ETH however SIA reports all shares rejected ?

I'm using the same command line for both versions.

EthDcrMiner64.exe -epool us2.ethermine.org:4444 -ewal xxxx  -epsw x  -dpool stratum+tcp://asia.siamining.com:7777 -dwal yyyyyy -dcoin sia

tried searching for others with same, but can't find any hits.

Any ideas would be great ? currently rolled back to 9.8 as it mines flawlessly.

[yonton]

Ok so I did the my first successful 1500 strapping on my two rx 470 4g. One is at 23 mh/s and the other 22. Up from around 19.5. Is that good? What can I do next for more performance!

For most cards yes. Some RX 580's I have don't need the pixel patcher.

1150 MHz core clock, 2000 - 2100 MHz memory clock should get you to ~29 MH/s stable with a good timing strap bios mod. Also run HWinfo 'sensors only' to check for memory errors and reduce the memory clock by 25-50 MHz until there are no errors.

[TechPark]

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.

Aug 11 driver
Your problems are elsewhere with the rig.
If you want to have a stable system you have to back to basics, find a good instruction online and do changes step by step carefully.
I have 3 rigs with W10 and they all work fine with Aug 11 driver.

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?

It is obvious that you do not know what to do.
Just google and find a good step by step instruction and follow.
That is it. You are not the first one nor the last one.

[TechPark]

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

You problem is elsewhere. I an undervolt/overclock with AMD Blockchain driver even with v10.0

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:

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

You are using outdated version of PBE. Find a good step by step instruction with the links to the 1.4.1 version

The most current version of PBE is v1.6. It now includes 'one click' bundled performance timings. Very easy to use. Just save your original Bios using Atiwinflash and open it in PBE. The 'one click' option automatically applies the bundled performance timings and then save the Bios and flash it using Atiwinflash.

This version applies performance timings to the 2000 strap by default. Any way to get it to apply performance timings to a lower strap?

The timing is applied according to what your cards memory type is. If you want you could copy it to the other timings manually by clicking on the strap you want to change and using the box on the bottom. I found it wasn't necessary and the cards are more stable than when I was just copying the 1500 Mhz strap to the higher frequencies.

So I have been using the latest Claymore version since it came out.

My rig:

ASUZ Prime Z270-P
8x RX 580 8GB Nitro+ (Hynix)
Windows 10
Blockchain Beta Official Drivers
Claymore Dual Miner v.10.0
Modded BIOS, OC through Claymore @162w from the wall per card
Dual mining ETH (233 Mh/s) +DCR (7000 Mh/s)


I am overall happy with the new update, but I have had some issues:

• Sometimes miner can't reach maximum speed. I open the miner, clocks and voltages are being set properly but hashrate lies in the 225mh/s area. A simple miner restart resolves the issue
• Computer freezes. This has happened 2 times in my rig and 1 time in my PC (same setup with 1 gpu only) in the last 2 days. Here is the last part of the log @Claymore in case you find something interesting here

I know the fun part is

Code:

01:32:32:963   10f0   Socket was closed remotely (by pool)
01:32:32:963   10f0   ETH: Connection lost, retry in 20 sec...

but this does not justify a computer freeze

Ok so I did the my first successful 1500 strapping on my two rx 470 4g. One is at 23 mh/s and the other 22. Up from around 19.5. Is that good? What can I do next for more performance!

1150 MHz core clock, 2000 - 2100 MHz memory clock should get you to ~29 MH/s stable with a good timing strap bios mod. Also run HWinfo 'sensors only' to check for memory errors and reduce the memory clock by 25-50 MHz until there are no errors.

Im up to 26 mh/ each now. at 1150 1950 -70 voltage. Past 1950 is black screen. Not bad for 470 4g

It should be higher. Try increasing the -ethi to 8. My eight card mixed RX 570/570 4GB/8GB rig is getting 28.5 to almost 30 MH/s dual mining UBQ.



If you are on Windows mining ETH make sure you have the blockchain drivers with the epoch Dag fix patch.
