FUEL Miner Performance and Power Usage

Wanted to take the opportunity to comment on something that comes up from time to time, and that is the quoted specifications, and performance of the systems, with hundreds of units sold and many repeat customers I am proud of the quality delivered, however it does not come without a significant amount of development and testing… Hundreds of hours of development and testing continue with the product as we are always trying to improve performance and efficiency, as well as other improvements to help various customers better support their environments…

Due to variations in ASIC quality, demanding specifications of memory types, some cards do perform faster than others, and while you will read various things online about 570/580 performance, the specifications quoted reflect the minimum guaranteed performance of the systems, some ship able to run 5% faster, but as I cannot guarantee that ahead of time the specifications quoted take a conservative approach…

Some details on where we are today….

  • Depending on the cards in a specific unit the power usage at 230Mh/s Ethereum will be either 1080W or 1120W at 230V, when enabling dual mining this will increase to 1200W or 1140W, I know it does not make sense it’s not linear, however GPU memory does have an impact on the performance characteristics and the power is adjusted to keep things stable, many users have come to expect our miners to run for weeks or months without being touched.
  • We always try and deliver units with Samsung based memory, as those units will run 240-245Mh/s, however with the 570 cards AMD is currently providing AIBs (XFX, Sapphire, PowerColor, etc.) Hynix and Micron (Elpida) memory, but they are not providing Samsung, that stopped when 470 production stopped for some reason… We are currently contemplating having production runs of Samsung based GPUs done for us since we have the option too, however the memory must be independently sourced and not bundled by AMD as it usually is…
  • To improve acoustics we implemented thermally controlled fans in all units, providing for a much quieter unit, and not pushing the CFM the unit would previously draw, even when not needed… As of this week’s batch they are a standard item on units, and will continue that way moving forward. The fans will spin up as needed, however in most environments they will stay fairly quiet, making running units in the office, or at home much easier…

We have been asked many times about the 16 GPU unit, while it is working on the bench, we are not finding the savings we were looking for in cost, however it does double the density so for applications where density is important, we will continue to finalize and make the solution available… The focus t this point is the thermal design allowing it to handle various environments without any problems…

 

Stay tuned for more, and as always do not hesitate to ask any questions…

 

Transition to Kaby Lake and Z270 CPU and Motherboard

As some of you may know the Z97 boards are being retired across the market, we picked up almost 200 in our last buy but they went quick. Have been testing a new setup with the Z270 and have it running well, still 8 GPUs as before, the transition is underway with units being produced from April 12 on using the new motherboard. No real user facing changes, systems still perform as they have been….
