Looking For The Efficiency Sweet Spot of GTX 1080 Ti

24, Mar 2017

When looking for the best settings for GPUs that will be used for crypto currency mining it is often considered a good practice to optimize them for better efficiency and not for maximum performance. Going for the maximum performance often results is overclocking and thus higher power usage for the extra few hashes, not to mention the additional heat and as a result the overall efficiency may not be as good. If you are looking for the optimal efficiency you will most likely try to reduce the power usage of the GPU to decrease the power usage and heat output and not sacrifice any or at the cost of just a little performance drop. This is exactly what we are going to be doing now with the recently announced Nvidia GeForce GTX 1080 Ti Founders Edition video card, trying to find the sweet spot in terms of efficient (best hashrate per Watt of power used)…

For the purpose of our tests we are using the latest NiceHash Excavator v1.1.4a miner running on the Equihash algorithm used by Zcash (ZEC). Do note that other algorithms may need different settings for reaching better efficiency than the one tested here. Currently the Equihash algorithm is among the most profitable to mine on Nvidia CUDA GPUs, so we are focusing on it. Since all recent GPUs from Nvidia have both a base operating frequency and a boost operating frequency and the video card is managing the optimal one based on factors such as TDP and temperature it is easy to look for better efficiency just by lowering the TDP limit. This will essentially result in lowering the maximum boost frequency of the GPU and is an easy and very good thing to start from, if you wan to dig deeper you may also try to lower the operating voltage of the GPU in order to further improve the efficiency by lowering the power usage.

In the table above we start with the GTX 1080 Ti running at the maximum TDP level that is allowed with the +20% increase of the Power Limit meaning 250W default TDP + 50W increase or a total of 300W allowed. At this maximum allowed level you cannot expect to be anywhere near the optimum efficiency, not to mention that the GPU may not be able to reach that power usage anyway without further overclocking. We are however going to stay at the default settings and not overclock, playing only with the boost frequency of the GPU by lowering the TDP. The final result showed that the optimum efficiency in terms of hashrate per Watt is with around 60% TDP or about 150W for the GTX 1080 Ti… that is for the Equihash algorithm used by Zcash (ZEC). With that setting the operating frequency of the GPU stays at just a bit shy of 1500 MHz, or to be more precise at the 1480 MHz base operating frequency. What essentially this means is that while the extra Boost frequency may rise the performance you get, the more it scales up, the less efficient the GPU becomes in terms of performance per Watt of power used. No wonder Nvidia has chosen this particular operating frequency as the base one for the GTX 1080 Ti, and the GPU manages to keep it up with a TDP of just 150W for mining the Equihash algorithm. Do note however that other mining algorithms, especially more GPU dependent, may need more power for their efficiency sweet spot on the GTX 1080 Ti.

NiceHash Has Added Support for the X11-Gost Algorithm

14, Feb 2017

You can now start selling your hashrate or alternatively buying such for the X11-Gost algorithm used by SIBCoin (SIB) on NiceHash. SIBCoin is mostly supported by the Russian community, but in the last couple of months it has been growing steadily and the addition from NiceHash may help in the coin getting more interest from the international crypto community. The coin has a CPU miner, though not much useful nowadays with the availability of GPU miners. You can download the latest release ccMiner by tpruvot for Nvidia CUDA support of SIB and NiceHash or the latest NiceHash sgminer fork for AMD OpenCL GPUs. The latest release of the NiceHash Miner v1.7.5.0 software also comes with built-in support for the new X11-Gost algorithm used by SIB.

NiceHash Currently Adding Support for PascalCoin (PASC)

4, Feb 2017

Interesting update coming from NiceHash as they have announced they are currently implementing support for PascalCoin (PASC) on their marketplace for users selling and renting hashrate. There are currently two mining pools available for PASC from Nanopool and from Suprnova and it is being traded on Poloniex with a very serious volume. Recently there was was a more turbulene surrounding the coin thanks to unexpected fork of the blockchain following a wallet update, but it seems that the issue has been resolved for the moment. We’ve had our doubts that PascalCoin may have a short lived pump and dump on Poloniex. It seems that we are past over that phase already with the user interest remaining and the support for PASC increasing, so you might want to keep an eye out for PascalCoin (PASC) if you haven’t been doing it already as of late…
