The new beta version is finally ready. You can download PhoenixMiner 5.7a from here:

PhoenixMiner_5.7a_Windows.zip (GitHub)
PhoenixMiner_5.7a_Linux.tar.gz (GitHub)



The new features in this release are:

  • Added lock core clock
  • The problem with the missing GPU temperatures on Nvidia GPUs is fixed
  • Added native kernels for AMD RX6700 GPUs. These are faster than the generic kernels and produce a lot less stale shares
  • Increase the max supported DAG epoch to 550 (should be enough to about Jan 2023)
  • Full support for setting clocks, fan speeds, voltages, and memory timings of AMD RX6900/6800/6700 cards
  • The specific hashrate is now shown in the form of kilo hashes per joule (kH/J). Example: if a GPU has hashrate of 30 MH/s with 100W power usage, the specific hashrate is 300 kH/J
  • Added new command-line parameters -ttj and -ttmem, allowing automatic fan speed control based on GPU hotspot (junction), and memory temperatures respectively. Example: -ttmem 83 will keep the GPU memory temperature at or bellow 83C by increasing the fan speed as necessary. These parameters can be combined with -tt, as well as with each other. These options are supported only on AMD GPUs that report junction and memory temperatures
  • Added new command-line parameters -tmaxj and -tmaxmem, allowing to decrease the GPU usage when the GPU hotspot (junction), or GPU memory temperatures are above the specified thresholds. These options are supported only on AMD GPUs that report junction and memory temperatures
  • Added support for AMD Windows drivers 21.3.2, and 21.3.1
  • Added support for AMD Linux drivers 20.50.x. Use this drivers only if you have Polaris or older GPUs, or the latest RX6x000 GPUs. WARNING: Vega, Radeon VII, and Navi GPUs won't work with these drivers!
  • Turn off the zero fan feature on AMD cards whenever a fixed fan speed is used (e.g. -tt -40), or when an auto fan with min fan speed is used (e.g. -tt 63 -minfan 35). To disable this feature, add -fanstop 1 command-line parameter
  • When -mcdag 1 is specified under Linux, the miner will not wait for the daggen.sh script to finish before starting to generate the DAGs. Instead it will for a fixed 7 seconds. This allows you to do all the following in the daggen.sh: turn off the overclocking of Nvidia GPUs, sleep for 30-60 seconds to allow time for DAG generation, and then re-apply the overclocking of the Nvidia GPUs
  • Other small improvements and fixes

The support for -ttj, -ttmem, -tmaxj, and -tmaxmem for Nvidia 3090 and 3080 GPUs is not yet ready for release. We hope to have it ready for the final 5.7 release.

For more robust integrity check, you can use our GPG public key, which was verifyed with ETH transaction from our main devfee account as explained here: https://bitcointalk.org/index.php?topic=2647654.msg56755869#msg56755869.

Please let us know if you have any problems or questions related to PhoenixMiner 5.7a.

I had $1000 to "waste" so I bought 116,000,000 SHIB.  That $1000 is profit I made on BTC, so I thought "Why not?"  It was just for fun, but who knows?

Not sure if this is the right forum for this but--

After this morning's update from Google Play Store on Android Blockfolio no longer works.  It crashes and disappears as soon as it is launched.  Anybody else seeing this?

Re: What percentage of investment BTC vs ETH
by

on 16/05/2021, 18:07:18 UTC
I went with a 75% BTC and 25% ETH for the time being.  Of course neither one of them is doing very well at the moment.  To answer an earlier post, I've been into BTC for several years.  I first bought a bit at $800 and added a little more around $3000 and continued up to about $12000, so I've made a bit of profit so far.  But BTC has slowed down while others have been galloping ahead, so thought it might be time to diversify.

It would be a case of trading some BTC for ETH.  I had thought of doing that when ETH was around $1700.00 but didn't.  Sigh....  But ETH and DOGE are around all time highs (ignoring the fact that they are down a bit today), and BTC is down, so it doesn't seem like a good time to do anything.

What percentage of investment BTC vs ETH

If you were going to invest in both BTC and ETH what percentage would you put into each?  At the moment I have 100% in BTC but am thinking of diversifying.

Are there a couple of others that you would suggest should get some of that percentage, such as DOGE or something else? If so, what percentages?

Re: When is Authenticator code needed?

Just to add some more information.  Today I transferred some bitcoin out of BlockFi, and was texted a code to use.   Afterwards I got an email requiring me to authenticate by uploading front and back images of an ID, and in addition required me to use my camera to scan my face as I gradually looked to my left and to my right.  Shortly thereafter it was approved.

As I know, Coinbase uses the Authy app for 2FA until 31 march. They will no longer be supported after this date. If you do not migrate to Google 2FA or Duo, they will automatically remove the 2FA protection from your account.
Which time zone use on your phone, is there any difference in other devices which had regular access to Coinbase? it was a problem for me at one point until I put it on automatic time zone determination.

All my devices show the same time zone, and I haven't been out of this time zone for a long time.  Also, because of previous suggestions, I had synced the time between the devices.

I am pretty sure that Coinbase/Coinbase Pro asked me for Authenticator codes and not Authy codes.

Each website you create a 2-Factor Authentificaion for also gives you a recovery code that you can use in case you encounter problems with your phone or the Google 2FA app. What is the status of those recovery codes, did you not write them down when you initially set up 2FA?

I have used a few exchanges that allows you to whitelist your device and IP address. The next time you login, it's enough to enter your ID and password and the site wont request a 2FA code. That's why you are still able to access certain sites without any codes.

I was unaware that I was given any recovery codes.  Coinbase, for example, simply sent me a verification code so that I could log in, unless this is the code you were talking about.  They sent me several such codes, presumably different ones for Coinbase and Coinbase Pro and for the three different devices I was using for access.  Of course, I now don't know which code goes with which device or app since they were all texted to my phone and have no differentiating information in the messages.

I guess I won't know anything further until I have occasion to execute a Coinbase/Coinbase Pro transaction.  Then I'll just have to see what it asks for and if it is something I can supply.

I think it's time for you to find a new phone then. I never know a phone that does that. Are you sure you don't modify something and install something like "deepfreeze" for your phone?

Pretty sure the backup failed or got corrupted. If you can't buy a new phone then I think using another authenticator client might be a good alternative. You should do it asap to make sure you don't lose your access to those exchanges, which will take a very long time to recover.

I did buy a new phone.  I went from an LG G4 running Android 6.0 to a Samsung Galaxy 515M (7 amp battery) running Android 10. 

There is an odd thing though.  After I knew that my Authenticator wasn't working any more I tried redoing my 2FA setup, obviously not knowing what I was doing.  Of course that accomplished nothing.  But the odd thing is that after rebooting the phone it never again deleted an app.  It could just be happenstance, but it is curious.  I retained my phone number, so the old phone is still usable for internet access, but it just gathering dust in a drawer.

It was suggested that I use Aegis, but without any Authenticator stuff working there is nothing to try to import to Aegis.

Not sure what's happening because I personally don't use Coinbase, but 2-factor authentication is mostly required by financial services to increase more security for their users and to prevent hackers/scammers from accessing their accounts and stealing their money.

Why did you "destroy" your authentication keys in the first place(or did it get destroyed unintentionally)? Knowing that Coinbase would require it every time.

I had an Android problem where after a phone reboot some apps were being deleted.  After googling around I saw that some others were reporting the same thing.  I got tired of having reinstall 4 - 5 apps every time I restarted the phone.  So I took a backup.  The next time I rebooted my phone and apps were deleted I just did a restore from the backup.  For some reason my Google Authenticator codes never worked again.  Somehow they were damaged during this process.

I had moved my funds from Coinbase Pro to BlockFi to take advantage of the interest they pay for deposited bitcoin.  Since that bitcoin movement I have not had occasion to again buy/sell/transfer any bitcoin using BlockFi.  I have been able to sign on/off BlockFi, but I would probably have had a problem if I actually tried executing a transaction.  I have initiated the process of getting re-authenticated (or whatever the term is) at the following site:

https://help.blockfi.com/hc/en-us/articles/360048862652-I-lost-my-2FA-Code-how-can-I-access-my-account-again-

However I still don't quite understand the Coinbase stuff.  They sent me a code to use to sign on, and an email to verify the device I use to access my account.  But wouldn't I expect to be asked for an Authenticator code if I tried to execute a transaction?  I don't see how it would now recognize my Authenticator codes.  I don't know anything I did that would allow it to.

 Coinbase sent me a one time code to use to login after my having been locked out, but I don't know if I will ever be asked for any other code. To clearify, each time I went to login on a different device they sent me a code to use during the login process.
Where do you receive the code? To your number? Then nothing else is required. That's the code I think. And in some cases, if the device used to log in your account is known to coinbase, they may not ask for code.

Yes, they sent it to my phone, and then during the login process they sent an email to which I had to respond on the same device that I was using to try to login.

But, you now have me worried about BlockFi.  If I am asked for an Authenticator code to withdraw funds it will fail.  I wonder if there is any other way to test this without actually trying to withdraw funds.

Your question isn’t clear to me.
Anyway, if you set 2FA (which you will be asked for with most of the reputed sites), you will be asked for code on every time you log in or withdraw fund. In case of coinbase, I used my number only and I am required to use the code everytime I try to withdraw fund.

Well, on BlockFi I log on and off a couple of times every day and am only asked for my userid and password.  This makes me wonder if I should try a small withdrawal to see they ask me for anything else.  Coinbase sent me a one time code to use to login after my having been locked out, but I don't know if I will ever be asked for any other code. To clearify, each time I went to login on a different device they sent me a code to use during the login process.

If I am asked for any code when withdrawing funds, I would have no idea what to enter.

I managed to destroy my Authenticator keys and just got re-enabled by Coinbase.  So, any time that I had been asked for my Authenticator code it would fail.  So, I could not access Coinbase or Coinbase Pro on my phone, but could access both on my tablet, and could only access Coinbase Pro on my desktop.  If any of these would have had occasion to ask for my Authenticator code it would have failed and then I would have no longer have had access.  I can still access other exchanges that use Authenticator codes.

So, my question is under what circumstances is one asked for an Authenticator code?

Going over this video it seems pretty easy to see the transaction history from the Coinbase App, and further viewing the TX details:
https://www.youtube.com/watch?v=WOtvWe3mqfE

The video is pretty recent, and the bitcoin price captured on the screen seems to be from february of this year, so the interface should be that of the current version (or so).


Yep, you're right.  There was nothing on the screen indicating that the "My Wallet" line was "clickable."  It showed the current value over to the right and I thought that was it.  Thanks much!

How about contacting the support? Maybe they can help you faster with it.

https://help.coinbase.com/en/more/coinbase-commerce

Coinbase help indicates there is an entry under a Profiles menu entry.  That entry must only be available on the desktop version as opposed to the mobile version.  I am currently locked out of the desktop version because of a clobbered security key and am working with coinbase about getting re-verified.  That should be fixed in a couple of days and I'll check again then.  I'll report back.  Thanks for the help.

Have you checked this yet? I'm not sure if this applies only to trading but it can be somehow related to this.

https://help.coinbase.com/en/pro/managing-my-account/account-information/account-history-and-reports

Anyways, how did you purchase the BTC? Like local currency? Credit Card? Etc.

I was using coinbase, not coinbase pro.  I purchased both with credit cards (don't remember which ones) and also local currency.  I realize that I can go back through all my credit card statements for the last several years, and bank statements, but I was hoping there would be an easier way.  After all, if the IRS can find the information it must be available somewhere.
