AMD R9 290 AMD Mining:Hashrate | Ethereum and ZEC mining on r9 290 | Profitability – Mining cryptocurrency on video adapters remains by far the most popular and affordable way of mining. Among the “miners” are actively discussed the strengths and weaknesses of certain graphics processors, as well as the level of their profitability. Let’s see how profitable mining some coins is on the AMD r9 290 card.
AMD R9 290 AMD Mining: Graphics card specifications
The increased interest in digital coins and a sharp increase in their value led to the emergence of powerful modern video cards on the market, focused specifically on mining. However, all these new items are notable for their high price and do not always justify themselves in situations when the crypt rate is going down. Therefore, many “miners” use old GPUs to mine cryptocurrencies.
According to experts, the correct settings for mining r9 290 allow you to achieve a high level of efficiency at a relatively low price. Consequently, this video card from AMD, presented back in 2013, continues to be relevant, being a kind of “golden mean” between budget and advanced expensive options.
Let’s dwell on the main technical parameters of the device:
- core – Havaii Pro;
- technological process – 28 nm;
- processor frequency – 947 MHz;
- DDR frequency – 1250 MHz;
- width of the GDDR5 bus 512 bit;
- memory bandwidth – 320 GB / s;
- memory size – 4 GB;
- maximum power consumption – 300 W;
- unified shader units (processors) – 2560;
- texture units – 160;
- interface for connection – PCI-E.
Another model of this video card, the Radeon r9 290x, is also widespread, which differs in a slightly higher frequency (about 1000 MHz), a large number of shader units (2816) and texture units (176). This uses the Hawaii XT core.
These developments were produced by all major manufacturers of computer equipment: AMD, ASUS, Sapphire, Gigabyte, MSI, Powercolor, FXF. Products from different companies may have their own characteristics and differ somewhat in their characteristics.
What crypto can be mined using a video card
Theoretically, you can “dig” any cryptocurrency on a video adapter. Another thing is that not all algorithms will be profitable. If we talk about Bitcoin, then the 290 and 290x models give out indicators of 547 Mh / s and 624 Mh / s, respectively, but this does not really matter, since this niche is tightly occupied by ASIC devices. Computing on a video card will not give a profit; at best, it will be possible to recoup the cost of electricity.
Therefore, experienced miners work on those algorithms that do not yet allow the use of specialized chips. First of all, we are talking about the following algorithms:
- Ethash (Ethereum Classic, Ethereum);
- Equihash (Bitcoin Gold, Zcash, Hush);
- CryptoNight (Bytecoin, Monero, Electroneum).
Graphics processors from different developers are more suited to work on different algorithms. For AMD, mining such coins as Ethereum, Zcash and Decred is considered the most preferred.
In addition, some “diggers” argue that, despite the increase in the number of specialized chips in the Litecoin network, mined with the Scrypt algorithm, there is still a chance to make money on this coin. If the 290x version is overclocked to 800 kh / s, then taking into account the small investment in hardware and relatively high energy efficiency, you can make a profit on Litecoin. Although the increase in the level of complexity of the network against the background of the high price of the coin will most likely close this window as early as 2018.

Ethereum and ZEC mining on r9 290
Thus, the main task of the Radeon r9 290 is Ethereum and Zcash mining. Correct hardware setup and installation of the most up-to-date drivers is very important.
Model 290 is capable of 28-30 Mh / s on Ethereum, and 290x – 30-31 Mh / s (according to other sources, up to 32.4 Mh / s). Much depends on the manufacturer and the memory installed on the card. If we manage to get a video card with memory from Hynix, then the indicators will be higher, but if the device has memory from Elpida, the results will be worse.
Ethereum mining is possible both in solo mode and in dual mode using the Claymore program. Here, judging by the discussions on the forum, the opinions of the earners are divided. Some believe that it is better to squeeze the maximum Ether in solo mode, getting up to 32 Mh / s, others see the prospect in “digging” the ETH / DCR pair.
Depending on the settings, dual mining of this pair is capable of producing completely different results. Anyway, on the forum, some miners talk about 28 Mh / s on ETH and 1200 Mh / s on DCR, while others – about 32.2 Mh / s on ETH and 900 on Decred. In this case, the card “eats” about 300 watts of electricity, and sometimes more.
Some miners are trying to find a middle ground between performance and energy consumption and argue that with an average ETH / DCR pair of 28 Mh / s and 800 Mh / s, respectively, the video adapter consumes only 180 watts of electricity.
What all miners agree on is the efficiency of mining ZEC on Radeon r9 290 / 290x video cards. The “official” performance of the 290 model is 286 Sol / s, and the 290x is 353 Sol / s. In practice, miners squeeze out of their iron up to 380-390 Sol / s, while the electricity consumption is only 110 watts and the heating of the card is normal.
The disadvantages of these GPUs include:
- high noise at work;
- overheating at high loads, it is desirable to increase the fan speed;
- energy consumption (+300 watts) at full performance (it is advisable to have a cheap or free outlet);
- dependence of indicators on the manufacturer of the memory (Hynix or Elpida).
Summing up, we can say that old cards from AMD Radeon r9 290 / 290x still have the right to life. They do not provide such performance as modern cards sharpened for mining, but they have a huge plus in the form of their price, which is 2-3 times lower. Therefore, on ZEC and ETH coins, these video adapters can compete with many new products in terms of cost / profit ratio.
