Short post to say that Bitmaintech has begun pre-sales (shipping september…or later) of a new X11 miner, the D3. It hashes at 15000mhs for 1200w, and it is a big improvement over current miners which are also more expensive. A lot of people are jumping on this as it becomes available, but please remember the rules of crypto. No pre-orders. Although Bitmain has a proven track record, this is still a pre-order and many things can go wrong. Keep in mind if you do get refunded for the order, they will pull the same trick on customers as PandaMiner recently did, which is pay back the USD value at the time of purchase. If bitcoin goes up you are out of luck. And of course, mid September at earliest. Which means difficulty will probably be much, much higher by then. But it may still be worth it, up to you to decide.
Edit: Seems Innosilicon is also pre-selling the A5 “DashMaster”. Cheaper and more hash. So there you have it, your gear’s ROI is uncertain.
There is a new update for Claymore’s ethereum dual miner, now at v9.7. Check out the thread here. Main points are incorporation of recent nvidia speedup for certain cards (mostly 1060) and ASM integration for RX460 GPU’s, which results in much faster mining for SIA/Decred/Pascal.
– Added ASM mode for RX460/560 cards, up to 30% speedup for second coin in dual mode.
– Improved ETH speed for some Nvidia cards.
– Improved speed in dual mode for Nvidia cards.
– reduced initialization time.
– a few minor bug fixes and improvements.
– EthMan: added ability to select several rigs.
– EthMan: several minor bug fixes and improvements.
New excavator update is out, with improvements for all CUDA algos. Check it out here !
- added DAG cache host memory storage for quicker DAG switches
- speed improvements for all CUDA algorithms
- CUDA faster DAG generation
- bug fixes for AMD cards
- added option to disable AMD support
Today I present to you the latest in the rig family, the 6 GPU 1070 mining rig. As usual, we have a cheap, efficient and portable rig rack. I’m sure this will interest many people due to the fact that AMD GPU’s are now quite expensive and still hard to find. People are buying millions of them. Millions. When history repeats itself (and it will), I will be buying them off ebay for insanely cheap prices. Nvidia high end cards, on the other hand, can mine multiple algos much better and will most likely have a better resale value. Moving on !
In this system we have the following components (or similar, buy what is on sale for decent price/quality) :
Skylake CPU (example) : Intel G3900
USB Risers : There are many models, with 6-Pin, SATA and molex connectors.
EVGA 1070, consider what is available at the best price. 1080/1080ti can work also but you may not be able to have 6.
Win10 works well (enable win10 mode in bios, install, then turn off), remember to disable all the nonsense and updates and to create a power profile that doesnt turn your stuff off. For other software you can get MSI afterburner, EWBF for ZCash, ccminer/excavator by nicehash or other for different algos.
Building an Nvidia rig is so much simpler and easier. The overall system is much more stable too. There is literally nothing else to do. Your GPU’s should be detected, if you set PCIE to gen1 and above 4g enabled in the bios (if available). There may be other options depending on your motherboard. Here are some results for the most profitable algorithms (power usage is for overall system, from the wall with wattmeter) :
- ZCash (380 to 435 sol/s). Mem -502, core +135.
- 65% tdp : 700w
- 75% tdp: 800w
- 90% tdp: 950w
- ETH (27 to 30mhs). Mem +395, core -150.
- 65% tdp : 700w
- 80% tdp : 835w
- 90% tdp : 920w
- LBRY (260 to 290mhs). Mem -502, core +135.
- 75% tdp: 805w
- 90% tdp: 910w
- DGB-Skein (500mhs). Mem -502, core +135.
- 65% tdp: 700w
- 75% tdp : 800w
- 90% tdp : 940w
You results may vary depending on core and memory clocks. It is more efficient to run at a lower TDP.

If you have miner specific questions, it is best to go to the bitcointalk thread and read up on it there, and ask your question there. Other than that, i’ll be happy to help, happy mining !
