Are They Good For Mining – GTX 1660, 1660 Ti, 1660 Super: Hashrate | MSI Afterburner

Are They Good For Mining GTX 1660, 1660 Ti, 1660 Super: Hashrate | MSI Afterburner | Best Settings and Coins| Overclocking – The new line of GeForce RTX 20 graphics accelerators based on the Turing architecture delighted both miners and gamers with their functionality. But the use of new technologies led to an increase in the cost of the production process, which was reflected in the cost of top models. The budget segment of gpu devices based on the new architecture is represented by Nvidia GTX 1660 and 1660 Ti.

Mining GTX 1660, 1660 Ti, 1660 Super: Specifications

Judging by the markings, the cards are released to replace the GeForce GTX 1060 GPU , let’s see how much better they are than their predecessor.

If we compare the video card with the 1060, then the GTX 1660 has more computational and texture units, which is important for mining. Unlike the flagship cards of the 20th line, ray tracing and artificial intelligence acceleration do not work in inexpensive models, but these technologies do not play a special role in crypto mining. GPUs gtx 1660 and 1660 Ti, may be of interest to owners of mining farms on green video cards due to their relatively low price.

First, Nvidia released the GTX 1660 and 1660 Ti cards, and a little later, the NVidia GTX 1660 SUPER model appeared. This graphics adapter is an updated version of the 1660 that replaces the older GDDR5 memory with the faster GDDR6. The rest of the NVidia GTX 1660 SUPER resembles the previous model. The same TU116 video chip, 1400 CUDA cores and 22 multiprocessor modules. The core frequency does not exceed the level of its predecessor 1500/1800 MHz, but the hashrate in mining is higher in the 1660 SUPER due to the faster video memory.

Best Hashrate to choose: GTX 1660, 1660 Ti or 1660 SUPER

After running a mining test for the GTX 1660 for comparison with the 1660 Ti, and the GTX 1660 SUPER, you can see that the model with the SUPER prefix, due to the use of more modern GDDR6 video memory, demonstrates higher performance than the GTX 1660 and at the same time its price is lower than 1660 Ti.

The test results showed that the more budgetary GTX 1660 SUPER is almost on par with the GTX 1660 Ti. Optimization of the chip for working with GDDR6 memory allowed to really increase the performance in mining.

Which manufacturer has released the best 1660 Ti / SUPER for mining, what to choose:

• Armor;
• Palit;
• Msi;
• Gigabyte.

It is difficult to give a definite answer, because comparative tests have not been carried out, and it is unlikely that the graphics processor of any of the manufacturers will be seriously different from the rest. An interesting option is the GTX 1660 Ti made by Gigabyte with a proprietary Windforce 3X cooling system, but this is one of the most expensive models.

As practice shows, even identical video cards assembled into one mining farm have a slight difference in hashrate among themselves.

What to mine with 1660 SUPER, the most profitable algorithm

When the equipment is purchased and assembled in the rig , you need to determine the coin to mine. Of course, you need to calculate the benefits of mining in advance, but the cost of cryptocurrencies on exchanges constantly fluctuates, so you need to constantly monitor the market in search of the most profitable option. To compile a profitability table for cryptocurrencies, open the WhatToMine mining calculator .

Important!!! While Big Ether costs more than 1000 US dollars for one coin, it remains the most profitable altcoin for mining on almost any graphics adapter model. When Vitalik Buterin’s project completes the transition to the new network, the green gpu miners will have several rather lucrative areas of work left in stock. First of all, this is the new Conflux (CFX) smart contract blockchain platform, as well as the MTP algorithm and all MimbleWimble forks.

Bitcoin and Ethereum have great growth potential and it is probably not worth converting them to fiat even at the current rather high price. It makes no sense to launch Cryptonight8 mining on 1660 after XMR left this algorithm. Mining for 1660 Ti RYO (cryptonight-gpu) and Haven cryptocurrencies can bring you good income.

But the most relevant at the moment is Ethereum mining . Use T-rex and Phoenix Miner mining software . However, tomorrow a new, more profitable option may appear. Keep your finger on the pulse of events.

Overclocking and lowering power consumption

The maximum overclocking of 1660 SUPER is possible with the latest driver installed. To increase the hash rate, you do not need to alter the timings. Adjustment of the memory and core frequency parameters when overclocking a GOU device is carried out using MSI Afterburner .

The setting options depend on the memory manufacturer. The 1660 SUPER and 1660 Ti can be equipped with video chips from Samsung, Micron or Hynix. On cards with Samsung memory, the memory clock can be raised over +1000, while the core clock is either left at zero or driven into a small minus (for example, -300).

Micron memory cards usually do not overclock more than +850 in memory, and the core is set to either 0, or a small plus (for example, + 50).

At first, 1660 cards with Hynix memory were considered an unfortunate purchase option. Miners could not overclock them on air higher than 26 Mh / s, and the miner who got the 1660Super graphics adapters with Hynix chips in the store immediately carried them back, and if they could not be returned, he bitterly cursed his fate. But only on some models the memory chips can be viewed without removing the top cover.

In most cases, you have to buy a card, carry it home and insert it into your computer. Then the Gpu-Z program starts and only then you can see what you got. However, craftsmen, in the end, found out that Hynix video memory does not mean a loss of profit at all. You need to set the memory frequency for this card to -1004 on AF and it will give out about 31.7 Mh / s on Ether… Tested on two versions of Palit 1660 SUPER graphics adapters. In this case, leave the core at zero, and powerlimit +60. Raising the power limit has almost no effect on the hash rate, but it leads to an increase in power consumption and excessive heating of the graphics core. But on other mining algorithms, 1660 cards with Hyunix memory require a higher power limit, and sometimes even transfer the core frequency to a plus. With settings for ether on BitTube coin and other MimbleWimble forks, you won’t get the maximum hashrate.

To reduce the 1660 Ti consumption in mining, set the Afterburner Power Limit of the video card in the range from 60 to 75%. To lower the core voltage:

• Move the Core Clock slider all the way to the left.
• Click on the three-step graph at the end of the line.
• In the pop-up window, raise the beginning of the graph to the required core frequency.
• Click Apply .

This will keep the voltage at 800 mV while increasing the acceleration. However, sometimes the graphics adapter may not respond to changes to the Curve setting. If a particular gpu device has Samsung video memory chips installed, you’re in luck. Video cards with memory from this manufacturer hold up well overclocking and are easy to undervolt. But if the video card has a Hyunix or Mikron memory, it is not always possible to lower the voltage using an afterburner. Then try the alternative.

You can lower the core voltage even further using the  NvidiaInspector . The program is not suitable for all video cards and is incompatible with other overclocking utilities. To configure overclocking and voltage, specify in a text file located in the program folder.

• TIMEOUT / T – delay interval before starting the application;
• SET FAN = cooler rotation speed;
• SET VOLT = core voltage;
• SET TEMP = target GPU temperature;
• SET GPU – card id starting from zero;
• -setMemoryClockOffset: – memory frequency (0,0,400 = +400 MHz).
• -setBaseClockOffset: – core frequency.

Change the file extension to bat, create a shortcut and place it in your autorun folder. The standard path is C: \ Users \ username \ AppData \ Roaming \ Microsoft \ Windows \ Start Menu \ Programs \ Startup.

If the farm is unstable, you need to identify the problem video card and increase the core voltage or reduce the overclocking. With too high parameters of the memory frequency, the software usually freezes, and overclocking in the core leads to the rig stop. The raisers may need to be replaced .

Conclusion

You should pay attention to the video cards of this line. Among the models from Nvidia, you can hardly find the best option for upgrading or assembling a new farm.

The GTX 1660 SUPER graphics card is superior in price / performance ratio . The card is cheaper than the older version of the GTX 1660 Ti, but almost as good as it gets. At the time of this review, the GTX 1660 SUPER graphics adapter remains one of the best options for building a budget mining farm. But, if you want to profitably sell used video cards later and are not particularly constrained in funds, buy Nvidia cards of the 30th line, or video cards from AMD 5700 XT .

Following the prices of Ether and other cryptocurrencies, the prices of video cards have skyrocketed. Moreover, the 1660 model is leading in terms of the growth rate of value, but, after all, Ethereum has also greatly increased in price, and this is not a ceiling yet. A farm of ten 1660 SUPER will earn you about 1,500 rubles per day, then count yourself.
