Latest ccMiner 2.2 fork by Nanashi Meiyo-Meijin For MonaCoin Mining

12 Oct
2017

It seems that the last day MonaCoin (MONA) has exploded in price and profitability for mining as a result, so there is increased interest from miners. So here is a 32-bit Windows binary (CUDA 8.0) of the latest ccMiner 2.2-based fork from Nanashi Meiyo-Meijin (source) with optimized Lyra2REv2 performance. The code is based around the ccMiner 2.2 release from tpruvot, but offers faster performance for Lyra2REv2 with up to about 10% (depending on the GPU being used) compared to other publicly available forks. The Lyra2REv2 algorithm is performing very well on Nvidia-based mining rigs, so with the current low altcoin mining profitability you might want to give it a try. The profitability of VertCoin (VTC) is lower, but still pretty high compared to some other coins and algorithms at the moment, so it is also an alternative as the profit for MONA can start to drop soon.

ccMiner 2.2.2 by Tpruvot for Nvidia GPUs With PHI and HSR Support

12 Oct
2017

There is a new update of the ccMiner fork from tpruvot v2.2.2 (source) available for Nvidia GPU miners that adds supports for new algorithms and comes with some other fixes and improvements. The two new algorithms introduced are HSR used by Hshare/Hcash (x13 + custom hash) as well as the Phi used by LuxCoin, there are improvements for the SIB algorithm for Maxwell and Pascal cards. The new version comes with a small fix to handle more than 9 cards on Linux (-d 10+), an attempt to free Equihash memory “properly” and –submit-stale parameter for the supernova pool (which changes difficulty too fast).

The official Windows binary releases on tpruvot’s GitHub are compiled with CUDA 9 and they do require a more recent Nvidia video driver version 384.xx or newer in order to have support for the latest CUDA version. We have compiled a 32-bit Windows Binary for CUDA 8.0 that you can download below, it does not seem much different performance wise, it can just be used on systems with older drivers without having to update the video drivers first with ones supporting CUDA.

New HDMI Display Emulators (Dummy Plugs) Available

11 Oct
2017

It seems that there is a new wave of HDMI dummy plugs coming from China at very cheap prices (At least if you order directly from there) that are based on the Headless Ghost display emulator. These HDMI display emulator devices just plug inside the main video card of your mining rig and simulate the presence of a display with up to 4K resolution. As a result your mining rig boots normally (if it does not boot without a display connected) and you can use a custom resolution when you are remoting the mining rig and/or not be limited by low resolution. It seems that the HDMI dummy plugs from China are mostly available under a brand called Fueran, though we’ve seen some photos with unbranded adapters as well (including some photoshopped images).

These new HDMI dummy plugs can be an interesting alternative to the commonly used HDMI to VGA adapters that most GPU mining rigs get equipped with, though do note that you do not get the option to connect any kind of display to them. With HDMI to VGA adapters you are able to connect a cheap analogue VGA connector equipped monitor or a KVM device for monitoring the rig directly or even remotely with an IP KVM for example. So the new HDMI display emulators just look cooler and take less space, but are not as functional and do not really come much cheaper anyway, though you can find them more expensive and you can even buy the original Headless Ghost at even higher price.

If you do not need the VGA output that the HDMI to VGA adapters also simulating the presence of a monitor, then these new HDMI dummy plugs might be just fine for you. The new HDMI dummy plugs are available through eBay and Chinese sites such as Aliexpress for a price that can go as low as $3-$4 USD, the prices in Europe or US is usually a few times higher than that. The only drawback when ordering cheap from China is that the wait time for the delivery can be inconveniently higher than ordering locally at a higher price.
