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:

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

Added coinlib to our links! https://coinlib.io/coin/MTC/ManateeCoin

ManateeCoin is updated to 1.2.1.6, Fixed a bug that caused incorrect time formats in exported transaction logs to be generated.

Now ManateeCoin GUI will display and export all date and time in standard ISO format.

ManateeCoin is updated to 1.2.1.5, Now it is possible to lookup transactions by PaymentID.

Only the internal function has been changed so there will be no binary release this time.

It is not supported at the moment, will be integrated in future releases.

Added 1234Pools to the pools list! http://cryptonote.1234pools.com/manateecoin/

The official pool is experiencing networking problems, I'm investigating the issue

Added SZZ pool to pools list! http://www.szzpool.com/mtc/

I'll consider contacting stock again.

ManateeCoin Wallet is updated.

Version 1.2.1.4 fixes a bug where log files are not properly saved on some computers.

All payments up to this post has been processed. Thank you!

Your payment has been sent to your MTC address, thank you!

I have sent 100 MTC to all users who joined the program and posted a valid MTC address!

If you haven't received your payment due to posting an ETH address, please get ManateeCoin client to create a new MTC wallet! https://manateecoin.org/

As promised, I have sent 100 MTC to all users who joined the program and posted a valid MTC address!

If you haven't received your payment due to posting an ETH address, please get ManateeCoin client to create a new MTC wallet! https://manateecoin.org/

Hi, you used a SouthXchange address but you didn't specify a payment id.
You won't be able to receive your payment if you use a public address without a paymentID.
I'm holding the transaction for you, please let me know of your paymentID so you won't lose your payment!

Hello, thank your for your interest in ManateeCoin.

But please be aware that ManateeCoin is not an ETH token. It is a separate technology based on CryptoNight algorithm!

I cannot send the airdrop payment if you post an ETH address. Please install the wallet and get a nice MTC address

Hello, thank you for your interest in ManateeCoin. But ManateeCoin is not an ETH token, addresses of ManateeCoin start with the letter M.

Announcing the first airdrop program.

First 100 people who follow the twitter account @manateecoin and retweet the announcement https://twitter.com/manateecoin/status/952078011871903745
