Please add the feature in addition to the -minspeed reboot by the number of video cards found in the system. When the graphics cards overheat the hashtate begin to decrease, especially in warm rooms, -r 1 reboot occurs. But sometimes not all GPUs are defined and for correct determination it is necessary to reboot the farm several times. By the way, I have a strange summary hashrate on version 11.8: all 7 GPUs 29MH/s, but summ shows only 160 + - and GPU farm restarts.

Win10 x64 corp LTSB, 6*MSI 480 4G non-ref, driver ver.19.3.2, Claymores dualminer 7.0 ETH+SIA

After night have a lot of messages "Application EthDCRMiner64. blocked access to the graphics hardware" and 2 reboots/12Hrs. No overclock, no downvoltage, stock config.
Have some ideas?

Today I bought this system to solve the problem by connecting 3* PowerColor 390x2 Devil 13 cards. This task is not running Windows, but expirience of another team say that it could be solved on ethOS. So.. as I said earlier, I bought this system. She loaded, spins the fan and after a short time to stop responding. The system stops responding with a single card, and two and three. The problem drivers? Tell me what to do?

Собираю корпуса самостоятельно, являюсь автором компоновки.

Cерверные 5U корпуса 19".

Почему именно 19" корпуса:

1. Занимает мало места.
2. Позволяет проще организовать приточно-вытяжную вентиляцию, разделение на холодную и горячую зоны.
3. Эффективнее охлаждение за счет мощных вентиляторов и конструктива "трубы".
4. Оборудование закрыто и нет опасности что-то опрокинуть, замкнуть электронику.
5. Может располагаться в любом удобном месте (серверная, промзона, гараж, подвал).
6. Проще сделать защиту от пыли/влаги.
7. Упрощение проведения ТО, модернизации, замены вышедших из строя частей.

Each rig uses two power supplies - one-on-motherboard 350 W and server 2 KW graphics cards for additional power supply. As the ventilation system is installed 3 Delta PFC1212DE.
Capacity rig - up to 6 cards, but for comfortable use recommend to put on five. Maximum VRM temperature according GPUZ 63 degrees Celsius, 20 degrees at the outside.
They work on an algorithm Etherium, about 160 MH/rig. installation density is almost the maximum for air cooling.
This arrangement allows a limited area to place a sufficiently large hashrate (about 1.3 GH / 42U rack). Customers are already working more than 15 such rigs 24/7 for more than 3 months, no problem.
