Mining on RX Vega 64: setup, overclocking and cooling

The RX Vega 64 video card was introduced by AMD three years ago. Back then, crypto enthusiasts had high hopes for the new lineup of red video cards, and in general, their expectations were justified. Although the cards were quite expensive and energy-intensive, and the hash rate on Dagger Hashimoto and Zcash was not that high. However, the performance of the video card when mining Monero broke all records, and within a week the price of the video card jumped one and a half times.

On the one hand, this is a very, very good device for mining, on the other hand, many people consider it unreasonably expensive, and the payback period is extremely long and in general the purchase is unprofitable, especially since a lot has changed in the crypto industry since their release. Let's see if this is actually true. Is it worth taking this device to earn cryptocurrencies, and also how much profit does the video card bring?

RX Vega 64 video card in mining, characteristics

RX Vega 64 entered the market on August 14, 2022, when cryptocurrency mining was already in full swing, which is why the characteristics of this device were initially intended not only as gaming, one of the decisive aspects, as the scope of application of the device, was mining, for which quite a lot was done emphasis when creating.

This video card was originally intended by Radeon as a competitor to the top-end GTX 1080Ti at that time.

One of the features of this device, which is definitely a disadvantage of the Sapphire Nitro + model, is the need for three 8-pin connectors, which further tips the scales in the confrontation between radeon RX Vega 64 vs 1080 Ti mining.

Standard RX Vega 64 mining specs compared to other cards:

The overclocking profile of a given video card for mining will definitely be different from the overclocking profile for, say, toys. Also, it is worth taking into account the cooling system, which performs excellently on all versions of the video card, with the exception of the device from Gygabyte; it receives a large number of negative reviews. When assembling the farm, the power supply is selected from 20% reserves to avoid critical overloads when operating 24/7.

When mining Ethereum, the option with lower core frequencies, about 1150 MHz, is more suitable, this is explained by the fact that memory frequency is more important for ETH. Please note that this device has very high power consumption, around 250 W .

Which model is better to choose for mining?

As a mining device, the RX Vega 64 already has its own, time-tested top models from various manufacturers. However, now cards of this series are not so often seen on sale. We list the most popular models of past years:

1. Sapphire Nitro+ Vega 64.
2. Powercolor Vega 64 Red Devil.
3. Gigabyte Vega 64.
4. Asus ROG-Strix Vega 64.
5. MSI Armor vega 64.

First place, in this list does not even require explanation, Sapphire Nitro+ are the best option for this video card for mining. For a good price of 49 thousand rubles, you get high power for efficient mining, as well as excellent overclocking potential and equally excellent cooling. A significant drawback is the power supply system; the card has 3 8-pin connectors.

The second place in our top is taken by the Powercolor Vega 64 Red Devil , which can easily count on the first. A special feature of this video card is the highest factory overclocking rates among other devices , as well as a very attractive price of 45 thousand rubles.

The third place is occupied by Gigabyte Vega 64 , which has a very affordable price of 48 thousand rubles, however, its technical characteristics are very limited compared to other models in this top; accordingly, it is also much inferior in quality to the first two models.

In turn, the video card from ASUS has excellent characteristics, high overclocking rates and excellent cooling. This model could be in first place, but the price of 53 thousand rubles is too high and this is its only disadvantage compared to its competitors.

MSI armor Vega 64 video card , which occupies the last line of the rating, is completely uncompetitive compared to the rest of the list; it is an ordinary air-cooled video card from MSI, which does not have any advantages over other models, its cost is at https://www.e -katalog.ru/ from 31,990 thousand rubles.

What to mine, profitable algorithm

The next question that is worth considering is which coin to mine in order to achieve the greatest profit, because the consumption of vega 64 in mining is very high? Once upon a time, one of the most suitable options was the Monero (XMR) cryptocurrency. The coin is based on the CryptoNightV8 algorithm and is traded on all major exchanges. Mining Monero on Vega 64 brought good profits.

But alas, on November 30, 2022, the XMR cryptocurrency, fleeing the occupation by ASIC miners, switched to the new proof-of-work (PoW) algorithm RandomX. This protocol is CPU-oriented, and now mining Monero on video cards is pointless. Graphics adapters, of course, can work with RandomX, mining productivity is very low and as a result you will remain in the red. What to do?

When mining Monero, the Cast XMR - Highspeed CryptoNight program is used.

To calculate and select the most profitable coin, use special mining calculators, which you can find on the Internet. Enthusiasts look for new projects on forums, and collect coins for future use, hoping to sell them at a higher price over time.

Most people use the Nicehash ; to set up, you just need to download and install the program on the official website . Then register on the website and enter the data in the program along with your BTC wallet. After this, all that remains is to click Start and the program itself will select the most profitable algorithm for mining. Payments are made in Bitcoin to your address.

Hashrate on different algorithms

AMD Vega 64 shows the following results when mining other, less profitable algorithms:

The owners of Vega mining farms were saved from ruin by the new anonymous currencies MibleWimble , Beam and Grin . A little later, the Rawencoin coin changed its mining algorithm, and became very profitable for mining on AMD video cards, including Vegas.

Ether mining is also a pretty good option. The coin began to grow again and taking into account the development of platforms based on the Ethereum blockchain, Defi, this crypto project has very good prospects. True, in the end, Ether will switch to POS and then only classic and other even less profitable forks will be able to be mined on the]Ethash[/anchor] algorithm. However, a new interesting project may appear, and the situation will change radically.

On a traditionally profitable crypto night for AMD Vega 64 cards, the altcoins HavenProtocol (XHV) and BitTube (TUBE) . The Haven coin has been pumped on exchanges for the last month and in terms of mining profitability it is almost as good as ether. At the same time, it is quite cold; when mining XHV, GPUs heat up less than when working on Ethash or KawPow, which is very important in the summer, especially in the southern regions. However, it is difficult to say how long the HavenProtocol rate will last in an upward trend.

To achieve high production productivity, you need to be able to configure the equipment correctly. Properly executed overclocking is an important condition for achieving maximum profit.

How to find out hashrate

You can find out your hashrate by entering your wallet address in the pool, but how can you check the results in the miner itself?

By default, the program's console window does not display hashrate or data mining results. To check your hashrate you have 2 options:

1. Command line option
2. HTML reports

Command Line Option: Simply press H on the command line to display power.

Press R to display sharing results. Everything is simple and clear.

display hashrate

If you want clean looking reports, then display your hashrate using the HTML reporting option.

HTML report: remember, when we first started we entered any number. This number is needed for HTML reports. If you forgot what you entered, then go to the config.txt file and find this line.

"httpd_port": 9999,

To check hashrate, results and connection reports, enter the following in the address bar of your browser.

https://127.0.0.1:9999/h

Where 127.0.0.1 is your local IP (it is the same for everyone) and 9999 is the port that we configured initially. You will receive a neatly displayed hashrate.

How to stop mining

Xmr stak is a pooled miner and by default it uses both the CPU and GPUs of the farm. If the specifications of your CPU are too low or if you do not want to use your processor for mining, then you need to exclude them from the program.

In the xmr stak folder you will find the cpu.txt file. Open the txt file and scroll down where you will find the following lines:

"cpu_threads_conf" : [ { "low_power_mode" : false, "no_prefetch" : true, "affine_to_cpu" : 0 }, { "low_power_mode" : false, "no_prefetch" : true, "affine_to_cpu" : 2 }, { "low_power_mode" : false, "no_prefetch" : true, "affine_to_cpu" : 4 }, { "low_power_mode" : false, "no_prefetch" : true, "affine_to_cpu" : 6 }, ], { "low_power_mode" : false, "no_prefetch" : true, "affine_to_cpu": 4 }, {"low_power_mode": false, "no_prefetch": true,"affine_to_cpu": 6

To prevent CPU mining, set cpu_threads_conf to NULL (equal to zero).

"cpu_threads_conf" : NULL,

This will exclude the processor from mining.

Adding lists of pools or new coins to the miner

The easiest way is to simply create a new batch file with the required coin, while the basic configuration will remain the same.

The information you entered when setting up the program will be stored in separate text files. Whenever you launch the miner, it will connect to the pool and start mining the coin that you configured.

Overclocking AMD Radeon RX Vega 64

The VEGA 56 model can be equipped with BIOS from VEGA 64 to improve productivity. But you won’t be able to modify the VEGA 64 firmware. However, there is another solution. WinAMDTweak.exe utility applies modified timings on the fly.

If you have more than one card, you need to write a separate line for each video card, remembering to change the serial number (-gpu 0; -gpu 1, etc.). The WinAMDTweak utility itself is not a miner. To start mining, use the Teamredminer . A sample of the settings is shown in the picture.

You can read more about setting up veg on ether on the miningclub.info forum.

Step-by-step setup of Vega 56/ Vega 64

I myself am the proud owner of them. And I would like to create a topic with the most complete information about Vega. And guides for setting them up.

Basic instructions working from foreign users

1)

https://www.gandalph3000.com/cast_xmr/howto-mine-monero-rx-vega/ From the creator of the cast_xmr miner with mini settings.
— Simple instructions without tools, Wattmans and other tambourines. 2)
https://vega.miningguides.com/ A hodgepodge here and flashing and turning on and off when starting HBCC and editing the registry.
Only for seasoned miners. — My personal instructions on how it all worked for me.
1)

Connect 1 Vega 56/64 into a PCI-Express X4 or X16 slot without risers directly into the motherboard.
2)
Format the HDD/SSD with Windows and install Windows 10 (this is important! Zero Windows, which was installed on the Nvidia card, adds hemorrhoids. Only a clean installation from scratch.
3)
Start the system.
3.1) Install this program - https://miningclub.info/resources/vykljuchaem-lishnee-v-windows-10.157/ kill updates, etc. 3.2) Increase the amount of virtual memory Control Panel/System and Security/Advanced system settings/ Additionally, click on the Settings button > Performance Options > Advanced > We see the inscription virtual memory and click Edit, specify 15 gigabytes for each vega. (If you don’t have that much memory, you can put 8 gigs per card, experienced people on the forum say it works like that) I have 4 of them, so we’ll put 60,000 MB. Initial size 59000 - Maximum size 60000 my case Initial size 32000 - Maximum size 32000 - should also work 4)
In the control panel, change the power settings Power supply / Change circuit parameters
Turn off the display: Never Put the computer into sleep mode: Never
click Save changes.
5)
Download the Blockchain drivers from the official AMD website https://support.amd.com/en-us/kb-ar...eta-for-Blockchain-Compute-Release-Notes.aspx
6)
Install the drivers and all their components and wait until the card calms down.
During the installation, we do not touch or pull anything, at the end of the installation the program will prompt you to reboot, usually when you click on it it may also freeze. We feel free to reboot the system. 7)
After installing the drivers, click on Games>Global Settings>we will have two columns 1 - Global Graphics (Radeon RX Vega) 2 - Global Wattman (Radeon Rx Vega) in the first column we need to click on the HBCC Memory Segment button and move it to position is on. And then click apply. The driver will reboot. There is an important nuance here. Sometimes the checkbox is already enabled, but HBCC is actually disabled. AMD is aware of this problem and, in principle, suggests not paying attention to it, that is, if HBCC is enabled and the hashrate is small, then just move the slider to the disabled position and lo and behold, HBCC will actually work.

then we go to 2 - Global Wattman (Radeon Rx Vega) and don’t touch anything there except the cooler settings. SPEED (RPM) Manually Set the slider to the on position and raise the cooler speed. This is necessary so that when you first start the miner, the card does not heat up to 78 degrees and does not start smoking with gaskets.

Let's launch the miner.
In my case it's cast_xmr. Example batch file cast_xmr-vega -S xmr-eu.dwarfpool.com:8100 -u 47BCGhAqrj8ZN5UQgLkW7x5qx7vrYQwMwHDiPsNEhQdMCbnC6UGYzP8GccsHPAUffN4c8NLJoU4bBMp2sjiXuwTx59gJZ7J -G 0 %* and We look at the Hashrate indicators, it should be 1500-1900 depending on the card. If the values ​​are less, turn off the miner and go to the driver to enable/disable HBCC Memory Segment. Leave the miner to work like this for 15-20 minutes. 9)
Turn off the miner using the q button.
If you click on the cross in the body file, there is about a 20 percent chance that the drivers will fall off (not very good for us) 10)
Transfer the card to the riser and launch the miner again.
If everything is ok, then connect the second card. We connect the card to a separate braid and the riser to a separate braid. This is not a 1050, it is very capricious in stock. 2 per braid = hemorrhoids. IMPORTANT! Do not connect 3-4 cards at once, out of the box they load the power supply hard and the entire system flies into an eternal reboot or crashes the drivers. AMD knows this problem and promises to fix it. When you connect the second card, an AMD CrossFire rectangle will appear in the drivers; it should be in the Off position. (Disabled, that is) Usually, if you turn it on one by one, it is immediately disabled, but if not, then turn it off. Now we have 4 columns, respectively, each card has its own settings and Wattman. We repeat points 8 and 9. Having previously added the following card to the body file in point -G 0,1, we make changes. 11)
Launch the miner.
And we go to Wattman to play. We set -10 for the core and -5 for the power supply and leave the memory at standard values ​​(800). As the miner works, every minute we add -5 for the core and -1 for power until we have a value of -20 core - 10 Energy consumption limit (%). I don’t recommend immediately setting the parameters -30/950/-10, because sometimes it turns into artifacts and the devil would understand why. After we have recorded local success, we do the same with memory. Here the step may be different. I throw 20 at a time until I get 940. I leave the stock somewhere, because Hynix is ​​so far from Samsung (well, you understand, as Valera says) 12)
If there are 3 and 4 cards, add them too one by one and repeat the whole process.
Sometimes it looks funny, 4 cards in the global schedule, three have HBCC disabled, one has it enabled, but in fact it works on all cards. 13) Launch the miner and enjoy stable operation.
When connecting 2 or more cards, the hashrate sometimes drops. I get somewhere around 1650-1900 h/s per second, depending on the card. And 1 error per 20,000 ball somewhere. Everything has been working non-stop for a week now. Consumption is somewhere around 220-240 per card. PS I will add screenshots soon to make it clearer. If there are any unclear points, write me and I’ll try to explain. Please don’t throw tomatoes at me, I know you sew all BIOSes with one right hand and timings with one left one and have been understanding the registry since birth. I wrote for beginners, just like me. Good luck to everyone!

How to reduce energy consumption

Power consumption is a very important point for this video card. The chipset is very powerful and consumes a lot of energy; when installing a video card in a farm, use risers with a 6-pin connector. Such risers are more resistant to surges and have strong overload protection.

Typically, power consumption is adjusted in MSI Afterburner. OverdriveNTool is better suited for this model . The utility allows you to set the voltage manually. Keep in mind that Hive and other Linux vegs consume more. To overclock Vega cards to 52 Mh/s on air, use win 10 + 19.6.3 + amd tweak. And you definitely won’t get such a hashrate with Teamredminer on a claymore or phoenix. Happy mining!
