The internal memory of my GPU, explanations

In this article we will explain the difference and especially the importance of knowing the type of internal memory that a graphics card has. For each graphics card, even if it is the same manufacturer, the same model, the internal memory may be different from one card to another.

How do I know my graphics card’s internal memory?

For this answer, we will use a software called GPU-Z at the opening of it after installation you will see this: we have framed in red:

  • The graphics card model which is an Nvidia GTX 1060 3GB
  • The type of internal memory that is Samsung

There are 4 different types of memory:

  • Samsung
  • Elpida
  • Micron
  • Hynix

Do not use this software to view the power consumption of your graphics cards, it is not reliable. Only a power meter will be reliable to know the consumption of your RIG.


What to undermine with my graphics card depending on the type of internal memory?

We often see on the internet many people who undermine crypto-currency Ethereum by not knowing the type of internal memory they own. It’s very simple, a Nvidia GTX 1060 3GB or 6GB graphics card with internal memory off Samsung or Micron will have a hashrate of 19-20 MH/s on the crypto-currency Ethereum. On the other hand, this same Nvidia GTX 1060 3GB or 6GB graphics card with internal Samsung or Micron memory will have a hashrate of 23-24 MH/s on the crypto-currency Ethereum. (even 25 MH/s!) It is therefore preferable when writing its lines to undermine a crypto-currency that uses the algorithm Equihash, Neoscrypt or other rather than a crypto-currency that uses the algorithm Ethash/Dagger-Hashimoto If one has Hynix internal memory or Elpida, this is valid for Nvidia. Regarding the difference in internal memory for other algorithms, this remains pretty much the same but you have to know that the internal memory Samsung is the best type of memory you can hope because the hashrate will always be higher compared to others.

  • Example 1060 3GB Equihash RAM Samsung = 320 h/s on Equihash algorithm
  • Example 1060 3GB Equihash RAM Hynix = 305 h/s on Equihash algorithm

Always do your profitability tests directly by displaying your hashrate on your profitability comparator, there are many articles allowing you to do this quickly and easily on Cryptos-Mining. For AMD, depending on the type of memory with RX, sometimes it will be difficult to exceed the 27-28 MH/s on the Ethash/Dagger-Hashimoto algorithm when the same graphics card but with Samsung RAM will be able to have a hashrate of about 31 MH/s. On the other hand with AMD, even having another type of memory than Samsung or Micron, it will be possible to exceed the 30 MH/s on Ethash-Dagger-Hashimoto, it depends on the model of your graphics card and especially if you have a correct modified BIOS. For AMD, we recommend the graphics cards RX 570-580 Sapphire Nitro +.


Example of the hashrate algorithm Ethash/Dagger-Hashimoto We could not finish this article without a concrete example: on the image above we can therefore observe:

  • Hashrate of 25 MH/s on the Ethash/Dagger-Hashimoto algorithm with a GTX 1060 3GB. (3 graphics cards for the test)
  • Power Limit to + 65%, which means a very low consumption. (But we didn’t have a power meter on hand this day)
  • A core clock A-200 because the Ethash/Dagger-Hashimoto algorithm is not dependent on the core clock, but it is highly memory-dependent.
  • Memory overclocked at + 900.

Second Test: Internal memory: Hahsrate Ethash 1060 3GB Samsung-2

  • Hashrate slightly higher than + 1000 overclocked on memory.
  • For the power limit, you lose in hashrate if you drop below + 65 and you do not win anything beyond.

There are two things to consider, however:

  • The tests were performed remotely, a loss of hashrate on the GPU0 (first graphics card) is visible.
  • We did not test stability over several days, only a few minutes.

Software used: Claymore Dual Miner There is another software competing with Claymore, this is “Ethminer” created by Genoil. After several tests, the hashrate was not conclusive with the 0.15.0 version.


Why can’t I undermine the crypto-monnaie Ethereum?

If you have an Nvidia 1060 3GB or other with only 3GB, you will not be able to undermine the Ethereum crypto-currency with Windows 10. On the other hand no worries with Windows 7 but for example we have mined a crypto-currency using the algorithm Ethash/Dagger-Hashimoto = PIRL This does not matter or affect your hashrate if you mine the crypto-currency PIRL, Ethereum , Ethereum Classic, UBIQ or other because the hashrate will be the same simply because they use the same algorithm: Ethash/Dagger-Hashimoto. If you want to know what DAG means or the only importance of benefiting from a graphics card greater than 3GB you can read this here. A quick and easy translation: The DAG is used to know the end date to undermine a crypto-currency with your graphics card depending on the memory size of it. The change in the size of the DAG changes to each mined block. We also see a lot about this on the Internet, the next impossibility to undermine the crypto-currency Ethereum with 3GB graphics cards. Main reason why people do not buy Nvidia 1060 3GB or AMD RX 4GB graphics card. Below is an image showing the size of the DAG arriving at 3GB with its deadline for Ethereum: Source: Investoon the size of the DAG is independent on each crypto-currency, this does not depend on the algorithm. You will be able to see the DAG of the other Cryptos-currencies using the algorithm Ethash/Dagger-Hashimoto by looking at this website which we quoted the source. To finish we would like to remind that the crypto-currency Ethereum should already be in PoS. (Proof of Stake = impossible to undermine) It is most likely that no one can undermine the crypto-monnaie Ethereum even before May 12, 2019.   If you have any questions, if you think it is missing something important to add or correct do not hesitate to write a comment.
