Do you mean SigmaX? I don't think that got released.

Sure it's 0x4ef245a8e91Dc0619865f0400403264D9d520DCf

Glad you got it worked out. 

In that case you may not have to export the private key at all. Try this guide instead but substitute 'ETC' for 'UBQ', except in step 9 I believe you need to select the ETH address you sent the UBQ to.

https://ledger.zendesk.com/hc/en-us/articles/115005200029-I-sent-ETC-on-an-ETH-address-how-can-I-recover-them-

It depends which wallet you are using for UBQ.

That's because you need to import the private key from your eth address before you will see it. If you want to verify it is there you can look up your eth address on a ubiq block explorer.

In order to recover the coins you need to export the eth wallet private key first so you can import it to your ubiq wallet. Unfortunately I don't have step by step instructions for you and it depends on which particular wallet you are using. You can probably find info in a FAQ for the wallet you are using with some searching.

For example if it is a ledger nano hardware wallet a quick search comes up with this:

https://ledger.zendesk.com/hc/en-us/articles/115005197905-Restoring-your-Ethers-ETH-or-ETC-without-a-Ledger-Nano-S

You should be able to find similar guides for mist/geth, parity, myetherwallet, jaxx, etc. with some searching. Same goes for finding a guide for the second step of how to import keys into a wallet. Google is your friend.

Well if it's unencrypted it should be even easier to export then shouldn't it?

Any idea how long the Cryptopia wallet has been down for?

You will need to export your private keys for your ETH address and import them into your UBQ wallet.

Yeah I've noticed that. I can set 950mv in each dpm state and the card will actually use 950mv in windows, but with the same BIOS in Linux it will use stock voltages of around 1150mv. To get around this I've edited the BIOS to just go ahead and use stock voltages for the higher dpm states but added a 287mv negative global offset...but for some reason dpm state 6 is still bugged. If I switch to that state I see the "AvgPwr" show as around 50W (which tells me it is using less than idle voltage) and it will crash. It should be at around 850 - 863mv in that state, just like it does for states 3, 4, 5, etc. but for some reason it doesn't.

It's a real pain in the ass and I haven't ruled that out as a cause for the instability (briefly switching to state 6 for whatever reason). I wish the driver would just do what it's supposed to according to the BIOS but nope. It does what it wants and what it wants is to be a dick.

Just to add to this now that I got it working and have some data...I've been testing 1 of my cards in Linux and it gets 28.5 (reported by Claymore's miner) using practically the same settings (-10MHz on the memory because 2060 seemed unstable), as opposed to 29.5 reported by Claymore in Windows.

GPU # 1 in this screenie:

However, the actual effective 24hr avg hash rate on the pool side (AFTER losses from stale shares and Claymore's fee) is consistently slightly higher than the reported hash rate in Windows. Meanwhile the actual effective hash rate of the Windows cards is 5% or more below the reported hash rate.

That said, Windows does actually seem more stable. I mined for over a month with no signs of stopping until I shut down the rig on purpose to do some maintenance. In Linux it crashes every once in a while even with a slightly lower mem clock and slightly higher power use and temps (so I'm assuming core voltage is slightly higher but I have no way to check for sure). Also no way to monitor GPU memory errors so I'm not sure if the crashes are due to memory clocks/timings or a lack of core voltage.

There's definitely a learning curve, but once you understand how to do it, you can just set it and forget it.

He doesn't explain how to fix the table pointers after you delete the extra bytes from the padding, but gupsterg @ overclock.net has a video for that here:

There's some more info in this thread too:

Wolf0 I could scratch you behind the ear till your hind leg shakes. That post on the Ethereum forums about how to apply a global voltage offset in the BIOS for Sapphire cards was what I needed.

You can check your real consumption with a wattmeter. You can use HWiNFO64, GPU-Z, or MSI Afterburner to get a rough "chip power" or "core power" reading (at least with any earlier cards...not 100% sure about Vega), but it will be less than your real consumption, because it doesn't account for memory or other subsystems of the card.

I would recommend latest stable Afterburner if you want to try undervolting if it will work (again...not 100% sure about Vega support). If not I guess you could use Wattman, but it's not the best tool. You could also try OverdriveNTool. Just google them for download links.

@oblione

4x vegas dual mining with no undervolt? That could be using more than 1200W. Check your consumption because you could be hitting the limits of your PSU.

@syncis

Not sure about cutting down on instances, but for the disk make sure you turn off the recycle bin, and if you're feeling adventurous you could turn off restore points. Each one uses 10% of the drive IIRC. Also the Claymore logs can add up after a while.

Finally got it working. All my problems were because of the Pitcairn card being in the system. When I use the radeon driver then it won't mine at all, because it says DRM version is 2.50, even though I'm only trying to mine on the 570. When I use the amdgpu driver for the 270 I can mine...but the dag fix doesn't work.

Now after taking that card out of the system I'm getting 28.4MH/s @ 1140/2030 on a 4GB AJR card using Claymore. Haven't tested the same settings in Windows yet but it looks like it should be on par. Now I just gotta try different miners to see what's fastest and optimize the BIOS for each individual card, but the path to Linux rigs is clear now.


Are you using the latest stable afterburner 4.4.0? It should work with the latest drivers and allow up to -200mV. Does for me anyway. Make sure you apply the BIOS signature check patch if you're running a modified BIOS (which you should be doing unless you just don't want a free +7 or more MH/s).

Undervolting the memory controller is not really worth doing. Keep it between 950 and 1000 for stability. You can just set that in the BIOS and forget it.

Well like I say it's crashing after 5 minutes and I can't use the ROCm kernel anyway (or amdgpu-pro driver either because I'm using Debian now but apparently you don't need that).

When you say it's 0.5Mh/s below Windows do you mean with or without the dag fix?

I can't even actually USE the ROCm kernel, because it uses the "radeon" driver for my 270, which in turn gives me an error about needing DRM V3.x.x instead of 2.50 (even though I am not trying to mine on the 270). I had to compile my own custom kernel with CONFIG_DRM_AMDGPU_SI=Y in the config and also amdgpu.si_support=1 radeon.si_support=0 in the kernel parameters. It was the only way to make it use the "amdgpu" driver for both cards.

Adding the kernel is easy though and there's no risk, because you can always just select the old kernel from the grub menu if it breaks. Just boot to your old kernel and uninstall the ROCm one.

Flashing the BIOS is no problem and I've already done that...but the other thing is that the -cclock/mclock/cvddc/mvddc params don't seem to work. I get the message "AMD ADL library not found" when it starts up and I don't know where to get those libraries or where to put them. I downloaded and compiled AMD "ADL_SDK_V10.2" (had to #include a couple standard libraries in the adl_structures.h file in order to do that) but it just gave me a useless "adlutils" binary, which also gives the same ADL library not found error when I try to use it.

Also apparently it crashes after a few minutes. Same BIOS works in windows for days, gets +1 Mh/s (24.3 in Win7 without the dag fix vs 23.4 in Linux), and I can even undervolt it further with afterburner. I have no idea what voltages or clocks it's actually using in Linux either because I have no way to monitor it. Only thing I can see is temperature and fan speed. I'm guessing the memory is not actually clocking above 2000 even though it's supposed to be 2050 which I set in BIOS. That would explain the lower hash rate. I added GRUB_CMDLINE_LINUX="amdgpu.vm_fragment_size=9" to /etc/default/grub as well but still not getting dagfix hashrates.

It's a fuckin' shit show trying to get it to even run, let alone run well.

linux peeps halp meh plezz!

I've gotten slightly further along by installing a bunch of the .deb packages from the amdgpu-pro 17.40 tarball and adding this line to my script:


But now I get "Cannot build OpenCL program for GPU 0/Segmentation fault" and also it only sees 3GB of VRAM. This is the same error I was getting on Ubuntu 16.04 (I'm on Debian Buster now).

https://i.imgur.com/t1e5W08.png

EDIT: nvm I got it hashing. Had to install OpenCL from the ROCm github. Also had to run Claymore without the script and just add the parameters to config.txt for some reason or I would still get the OpenCL error.

Could use some help getting hash rate up though. I'm still getting pre-dag-fix hashrates. I already added "amdgpu.vm_fragment_size=9" to the /etc/default/grub file so not sure what else to do there.

Also getting "ADL Library not found." I downloaded and compiled AMD_ADL_SDKV10 and just got an "adlutil" binary, which also gives the same error when I try to run that.

They come from oc.net PBE thread. Look under 480/580 Performance Timings spoiler in the OP

http://www.overclock.net/t/1604567/polaris-bios-editing-rx5xx-rx4xx/

halp! I am trying to mine on linux but I get the error "No AMD OPENCL or NVIDIA CUDA GPUs found, exit"

I have an R9 270 and an RX 570 in the system, but I am only trying to mine on the 570. I have a few different opencl libraries installed and the AMD-APP-SDK v3.0.

Below is the output from lspci -v and dpkg -l as well as my mining script. What am I doing wrong?
