I'm concerned about the hash rate but way more concerned about the power draw, this higher power target makes it very difficult to power these-2100 watts each?!? Especially for larger purchasers the difference in power bills will be astronomical. The worst part is they originally targeted 1200w and then raised the goal to 1600w and we're still way off. As someone with several units on order this is very concerning, now even the highest density colocation cabinets running three phase won't supply enough power...I'm going to have to redo all our power plans, this is awful. Apparently I should have purchased the stupid terramine hosting package when it was $3500 but who knew they were going to miss the 0.6W/GH goal by this much become 1.2W/GH. This is insanely stressful, sigh, this is almost as bad as the issues people had powering minirigs.
The problem is that power rates where we are will run 0.25 per kWh so this is insanely expensive to run now
Yes, I am very disappointed also. This is going to be a very big issue for some enterprise customers who may now have to under volt and under clock these devices to maximize the use of their data centers. Cointerra has been going in the wrong direction since their initial estimate of 1.2 kW or better at the wall per TerraMiner IV. Also, they have not yet broken the $3 GH/s barrier, not unless they are refunding the difference.
As for me personally, the biggest mistake Cointerra made was bragging about their ability to perform within a small time frame before delivering a single TerraMiner IV. From one top Electrical/Electronics engineer to another, you should always let your customers do the bragging for you. I give them credit for having the best value in the market and I hope that they continue to have the best value.
So hopefully, some of you will receive your TerraMiner IV Bitcoin miners some time in February, unless of course, certification takes longer.
