Secret sauce BIOS mod for RX 5700 Graphic cards.

mineshop.eu — Sat, 03 Oct 2020 20:15:10 +0000

Timing Bios mod for AMD cards is nothing new for increasing performance on Ethereum mining. Lately also available for RX 5700 graphic cards. Most simples is just applying 1500mhz straps down bellow, which increases performance by roughly 10-15%. But there is more to that, i was playing with the rom files. And figured out that editing Dram 12 timing also increases performance for mining ETH.

Mining is basically competition whoever can do most efficient. And you want to rigs run as efficient as you can.

So the steps are following to increase another 1-2 mh/s on top of your 1500mhz strap bios mod.

1.By default 1500mhz and down bellow DramTiming12 is set to 2850 and on some cards 2945.

2. You need to edit this to at least 6000 in (1550mhz,1750mhz,1800mhz,1875mhz,2000mhz). Some gpus timing starts from 1500mhz it really doesnt matter which bios you have. I tried both of these and seems like it is working just fine.

3. I have tested this on Asus Strix RX5700XT and also Gigabyte RX5700XT

What i have noticed your cvlt and mvdd also has to be low as possible , my cvdd was set to 760.

Im sure there is more to it and we can increase more performance by adjusting these timing. This process is very time consuming, and im sure people will find how to adjust more of this to increase mining speed.

Soon 4gb DAG file for Ethereum mining , how to increase mining time for 4gb cards.

raia — Thu, 20 Aug 2020 13:06:12 +0000

So Ethereum mining is very interesting. There is this thing called DAG file, which is processed in mining. Basically it is a file which is been loaded onto graphic cards memory. As ethereum block-chain size grows also DAG file size grows. Precise exactly 30000 clocks which is roughly 100hours. Current DAG file size at the time of writing this post is 3.78gb.

So how does the DAG file affect mining?

Graphic cards usually comes with memory size 2gb,3gb,4gb,6gb and so on. This means if the DAG file is bigger then the memory module size on graphic cards , you simply wont be available to mine with your graphic card. If your GPU memory is bigger then DAG file ,you will be available to fit this DAG file on your card and mine with it. There is a lot of cards dropped already from mining ethereum.

But biggest drop probably will be when DAG file reaches 4bg size, because most of the mining farms where using 4gb RX 570/580/470/480 for mining Ethereum. Because they have been the best price per hash and best watt per hash. If we check hiveos software statistics we can verify this https://hiveos.farm/statistics/ :

23% RX 570 4gb
14% RX 470 4gb
12% RX 580 4gb
2% RX 480 4gb

Roughly 50% from all AMD cards using hiveos is 4gb cards, and AMD has been the best performing Graphic cards for Ethereum mining.

So there is few things what you can try to expand you mining life with 4gb cards. They already are starting to make issue. Using software like Ethos and claymore miner, incorrect drivers etc…

So the things to do :

1. Ensure you’re running HiveOS on the latest stable version and updates.
2. Switch your miner to the latest version of TeamRedMiner, Ethminer or Phoenixminer.
3. If your CPU has built-in graphics (iGPU), you can try enabling Internal Graphics on your motherboard’s BIOS and ensure it’s set to Default (Only applies if you have a monitor connected).
4. If you’re still running into issues after trying the above, try removing the “REF” parameter in the overclocking panel.

Using phoenix miner you will get the cards working till at-least epoch 372-373 which is end of October. You can achieve this also on windows but you might run into issues if you run incorrect drivers, best drivers to use is 18.12.1.1 to 19.7.5

Ethereum classic DAG file will reach Epoc 372 slightly faster around mid September , So i think Ethereum classic is in trouble of getting 51% attack around that time.

Hidden mining profits nobody is talking about

mineshop.eu — Tue, 21 Jul 2020 14:21:51 +0000

Ethereum mining recently has been very interesting. And there is hidden mining profits that nobody have been talking about. What i mean by nobody is that some of the mining calculators will show you different/incorrect current Ethereum mining profitability.

First off all you need to understand how Blockchains work , so for example Ethereum you have the block rewards which is currently 2 ETH paid out to mining pool who finds the block averaging 15sec a block (13500 ETH/24h)

Then there is transaction fees, to process transaction on Ethereum you have to pay GAS fee which is calculated in Ether . All these transaction fees are paid out to mining pool who has found the block and recorded all these transactions on this block. These transaction fees currently is over 5000ETH/24h .

The fees are at the highest they have been, since May up-till now they are higher then total bitcoin fees.

So this is where the hidden ETH mining profits are coming from. To test this out i have tested 11xRX5700 gpu Ethereum mining rig for 24h mining on hiveos ethereum mining pool.

Conclusion is that check multiple mining calculators to get the most accurate result . Like cryptocompare mining calculator does not have latest data from transaction fees, whattomine showing accurate results for me. Or the best solution test yourself, pools sometimes also could affect your payot amount, depending on size of the pool and payment structure.

Which mining pool do you get the best results?

Antminer S17 custom firmware up to 85TH.

mineshop.eu — Mon, 27 Jan 2020 20:58:39 +0000

For years now there has been possibilities to increase Bitmain bitcoin miners “antminer” efficiency with custom firmware. It is understandable that Bitmain don’t want their customers to change overclock on their asic miners. OC changes could possibly kill or damage hardware in some cases when chip oc and voltages applied to much. Overclock could kill miner it self or power supply. This is one of the reasons why Bitmain lately locks down their miners firmware, they dont want customers to do any changes on them.

The factory settings are standard, whoever is mining for while now. Knows that from some chips you can get better efficiency, just because quality of every chip is not the same. Lately there is been released an upgrade firmware and manual for Antminer S17 from hiveOS. HiveOS is gpu and asic miner monitoring/remote control. They previous firmware for Antminer S9 and T9 has been very successful. We have done review on this firmware also, and the best feature what Bitmain original firmware does not have is auto-chip tuning. It works very well, basically it finds the most optimal chip oc and the voltages to reach best efficiency.

We have now also tested the new firmware for Antminer S17, it does perform much better then Bitmain original firmware.On Antminer S17 53TH/s version , air cooled miner we where able to reach 75TH/s @3300 watts. It worked very well and setup is straight forward. It is possible to reach even better performance up to 85 TH/s , but you will need immersion cooling. As with air cooled at 75 th/s our miner chip temperatures where close to 80c at room temperature 15c. Also be careful , Bitmani stock power supply Antminer S17 max power usage is 3500 watts.

hiveOS asic miner the installation guide :

Notes

And now let’s go back to the installation process. There is no universal manual, for S17 and S17 Pro there are 3 versions of stock firmware. Therefore, every particular case has its own manual on the custom firmware installation.

Please note, that all the manual steps which involve using BTCTOOLS can be done via ASIC’s web interface (BTCTOOLS is usually used for a large number of devices).

Preparation Stage (required for all the options):

1 .Download and unzip the following archive: http://download.hiveos.farm/asic/repo/fw/Antminer/s9k-s9se-st15-st17-installer.zip.

Scan the network using BTC_TOOLS and export the list to csv. From csv, copy the IP list and insert it in ips.ini. In case you don’t have a lot of devices, you can make this list manually. Or use bitmain ipreporter tool.
Go to config.ini and check login and password for the ASIC’s SSH or web interface. If the password for the web interface was changed, the same would be for SSH. Set up FARM_HASH to connect to Hive or API, if necessary.

Download the firmware file (it has to have “Hiveon” in its title): http://download.hiveos.farm/asic/s17/

For S17 and S17 Pro, we offer the same firmware file. However, there are two options: “signed” and “nosigned” firmware. The signed firmware can be updated ONLY to another signed Hiveon firmware via ASIC’s web interface or BTC_TOOLS. Third-party or official firmware can’t be installed in this way. However, you can use the rm -rf /etc/bitmain-pub.pemcommand — send it to your ASICs via the Hive web. It will temporarily delete the certificate, but you can reboot your ASIC to bring it back. After this, you will be able to move to any firmware via the firmware update menu (in the Hive web). It will be possible to choose the firmware from the list or to use the URL.

The signed firmware can be downloaded here: http://download.hiveos.farm/asic/s17/Antminer-S17-S17pro-Hiveon-1.00-sign.tar.gz

If the stock firmware of your ASIC is released before 1 July 2019

Flash your devices with a file from the archive “remsigallbefore_2019–07–01.tar.gz”. This can be done via either ASIC’s web interface or BTC_TOOLS in case you have a lot of devices. You will see an error in status, but this is okay — it should be like this at the moment.
Flash the devices with the firmware file. Again, this can be done via either ASIC’s web interface or BTC_TOOLS.
Launch “3hashfarmforsigned.cmd” from the archive. The ASIC will get connected to the web.

Stock firmware released from July 2019 to December 2019

Launch “1openssh.cmd” from the archive and wait for the script to be performed. The devices will be rebooted. After the reboot, wait for around 3 minutes.

Launch “2upgradereplace.cmd” from the archive and wait for the script to be performed.

Flash the devices with the firmware file (via either ASIC’s web interface or BTC_TOOLS)

Launch “3hashfarmforsigned.cmd” from the archive. The ASIC will get connected to the web.

Please be aware you could damage your hardware by applying new overclock to your Antminer S17 .

StrongU STU-U6 dash coin miner review.

mineshop.eu — Mon, 16 Dec 2019 16:58:37 +0000

So StrongU STU-U6 miner for X11 mining algorithm is been a big failure. On pre-sale few month ago i purchased it with advertised setting 660gh/s at 1300w .Which to me looked like a very attractive deal. But as usual with Chinese asic manufacturers there are problems, the deal seemed to good to be true. So finally we have received the miner which supposed to deliver in October 2019, but got delivered in December 2019. And delivered not as it was advertised, received specs :

440 GH/s mining speed
2050 power usage from the wall

This supposed to be the most efficient asic miner for Dash coin , as the Spondolies SPx36 miner is very overpriced and uses lot more power. Dont get me wrong StrongU STU-U6 is still most efficient publicly available Dash Coin miner. But it is not as efficient as it was advertised. My power cost is quite high and watt per hash was 2x better when pre-ordered, and received a miner which nearly doesn’t cover my power cost.

I seen some posts that some people have ordered before me and have received miner with the specs it was advertised. So i assume they have had some bad silicon run or some other issues why they cannot reach full performance.

Has anyone received full performance 660gh at 1300w?
