If you are mining crypto currencies under Windows as operating system, then you have probably reached to a state when you have to clean up the mess created by a older or newer version of a video driver more than once already. Having to boot into Safe Mode and manually clean up the mess, hoping that everything will work fine again once more after you reinstall the video driver. There is a very useful and quite handy tool available that can help you do that with just a click of a button and save you some trouble and headaches. The software is called Display Driver Uninstaller and is absolutely free, so the next time when you have to play with video drivers you can give it a try if you still haven’t used it. With that said, the DDU software is useful not only for GPU miners, but also for regular users that may experience video drivers messing up. Issues with video drivers like some cards running an older while others are on newer version for example do happen more often on GPU mining rigs where you normally have six video cards than on a regular computer with just one.

With the recent craze with the price of Bitcoin as well as many altcoins rising up there is a huge wave of new GPU mining rigs as well as new crypto miners getting into the game. We already know that there are shortages of the very popular AsRock H81 Pro BTC motherboard for 6x GPUs for a couple of months now, but even more recent and more expensive motherboards with 150 and 250 series of Intel chipsets that support up to six video cards are also disappearing from the market. Next are probably the high-end gaming motherboards with 6x PCI-E slots that will work with six video cards if the trend continues. The Pro BTC motherboard from AsRock is hugely popular as it was designed for GPU mining and works out of the box, for other motherboards you need to usually do some tweaking of the settings and not all models have the right settings available in the BIOS or may have some specific issues. Another serious advantage of the Pro BTC series is the price, no extras not needed for mining means lower price point, though at the moment the demand and speculation has risen the price of these boards as well (if you manage to find one).

It is quite interesting why when there are shortages of H81 Pro BTC motherboards AsRock still hasn’t found a solution such as releasing a version of their mining motherboard with more up to date Intel chipset such as B150 or B250 for example. It seems that the competition is also trying to take advantage of the situation and grab some of the market that was up until recently dominated by AsRock. Such an example is the recent release of the Biostar TB250-BTC motherboard. The problem with Biostar however is that the brand has a much limited distribution when compared to AsRock and thus is harder to find, not to mention impossible for many markets around the world, so this is actually not a solution to the problem.

AMD’s new Ryzen motherboards are showing some potential for possible use for GPU mining rigs, however there is one serious issues with that platform using the new AM4 CPU socket and that is the lack of cheap low-end processors. That is precisely why Intel is the preferred platform for GPU mining – cheap Celeron processors that do the job well and not so expensive motherboards, though with the lack of AsRock H81 Pro BTC boards the expenses for a motherboard have risen as well. Maybe when AMD introduces lower-end Ryzen APUs things might get more interesting for the miners as well, especially if things with the availability of cheaper Intel motherboards that work for six video cards do not improve meanwhile. Even the cheapest AMD Ryzen 5 CPU at the moment, namely the 4-core/8-threads AMD Ryzen 5 1400 is too expensive for miners when compared with Intel Celeron G1820/G1840 for Socket 1150 or Intel Celeron G3920 for 1151 for example.

With the switch from Radeon RX 400 series of GPUs to the new (rebranded) RX 500 series AMD has also gotten into a bit of trouble with the increased demand from miners. The older RX 400 series of video cards are quickly disappearing and there may not be enough RX 500 series on some markets to cover the demand until the company manages to deliver steady supply everywhere. As a result we have seen some markets that end up with higher priced RX 500 series of GPUs when compared to their RX 400 counterparts when there is actually not much of a difference. Smaller markets are also experiencing serious shortage of video cards due to the increase in demand. Nvidia on the other hand has plenty of GPUs available, however miners are not that much into mining with Nvidia-based video cards due to the higher price, even though they generally are more powerful and use less power in most algorithms. The higher price of Nvidia GPUs combined with the not so great Ethereum (Ethash) mining performance however is driving the demand for AMD GPUs and the recent spike in ETH price has made things even worse in terms of Radeon GPUs availability. Guess we’ll have to wait and see how things will go, but if the price of crypto currencies continues to rise like it has been recently things may get even worse.

Pumps and Dumps in the crypto world are something we are often seeing happening only only with more established and popular coins, but also with crypto coins that you may not have even heard of. We are not big fans of actions like these as they are used to help some people make even more money out of unsuspecting users. Normally regular users have absolutely no idea when and what a pump and dump may happen, so they can hardly profit from them, but what if you can join and make some profit as well? Here comes CoinData, a cliometric based trading tool that tracks trading volumes on the exchanges and helps you signal when a pump and dump might happen. With it you can see the whales’ trading intentions through the volume they trade: buy / sell walls appearing / disappearing, preparing to pump or dump the actual coin you trade.

You can track trading volumes or crypto coins or buy walls appearing manually, but tracking even a few of the top coins on a single exchange might be hard enough, let alone doing it for all and on multiple exchanges. That is where CoinData comes with help by giving you up to date information on all coins traded on Poloniex and Bittrex (for the moment) and giving you signals when a coin is probably going to be pumped up or dumped, so you can make the right move and buy or sell. The service also reports on when a buy wall appears as this is usually a sign that a pump can soon be happening, making the coin interesting to monitor. To make things easier you even get real time notifications to help you keep track of what is happening when you are not watching the tables with trading data.

Do note that the service provided by CoinData is not available for free, there is a subscription fee that you need to pay in order to access real time data. There is a 1 day and 10 days trials available to try out the service as well as 30 days and 60 days regular subscription available should you decide to keep using the service after you try it out. We are currently testing it and so far our initial results are more positive than negative. Be wary that some of the signals you get may not turn out to be real pump and dump and sometimes you might still end up losing instead of winning by getting into the game, so be careful should you decide to get in with larger sums. On the other hand if you trade with too little coins, then the subscription fee you pay for the service might not be worth it if you are unable to profit enough to even cover it.
