When changing a whole new chip, it is necessary to tin the chip pins and then solder them on the hash board. Utilize thermally conductive gel evenly around the chip’s area, then lock the heatsink.
Repair approach: Examine the looks, evaluate the chip capacitor or resistance in front, normally It truly is attributable to lousy chip soldering or maybe a chip capacitor, resistor detrimental or irregular resistance;
② Visually inspect whether you can find obvious signs of burnt pieces, areas effects offset or missing elements, and so forth.
Servicing technique: Check out the looks and measure the capacitance or resistance in the front chip. Usually, it can be a result of very poor chip welding or problems and abnormal resistance of a specific chip capacitor or resistor, or problems with the chip by itself;
a) Liquid crystal display Screen ASICNG: if (0), initial measure the full voltage on the measuring domain as well as the Improve circuit 20V is ordinary, and afterwards make use of the quick circuit probe to short-circuit the RO examination level and the 1V8 take a look at stage between the initial and the 2nd chip, after which you can function This system to discover the chip.
Or The 2 ASIC chips During this domain will not be soldered effectively. Many of them are a result of brief circuit of 0.8V and one.2V patch filter capacitors (evaluate the resistance from the patch filter capacitors connected to the back and front sides of the PCBA).
If there isn't any 3.3V output, check the relationship standing in the hash board tester cable and the hash board.
2. Enter the consumer title, password and test command to check the NONCE reaction position and also the standing of voltage domain. In the event the NONCE and area voltage are irregular, consumer can carry out measurement and maintenance based upon the printed irregular chip.
APW12 electrical power supply: AP12_12V-15V_V1.two and electrical power adapter cable. It is suggested to work with thick copper wire for your positive and adverse poles of the ability source to connect the power offer and the facility board and only restricted to PT1 and maintenance take a look at use.
Windows mining Our mining monitoring and administration program for Windows GPU rigs is an ideal solution for those who prefer to mine on their own Home windows devices.
Generally, There exists a difficulty Together with the connection involving the hash board along with the Handle board. Verify the cable to see if there is an open up circuit. In case the relationship is OK, the consumer can check The only board PT2 to examine if it may pass the check. If it passes the exam, it could possibly generally be determined that the problem is around the Command board. In case the exam fails, make use of the PT2 repair system to repair it. three) Abnormal temperature: Commonly, It really is due to temperature is higher. The PCB temperature set by our monitoring process are not able to exceed ninety degrees. If it exceeds 90 degrees, the miner will alarm and fall short to work Generally. It will likely be attributable to high ambient temperature and abnormal fan Procedure with the miner not to have the ability to operate Generally. Abnormal followers operation may also trigger irregular temperature. 4) Are unable to come across the many chips (boot is often operated, even so the hash fee is 2/three or 1/three of the conventional worth). The volume of chips isn't plenty of: if the quantity of chips just isn't enough, you are able to check with PT2 for screening and repair. Figure six-4 5) Soon after operating for just a timeframe, there is absolutely no hash level, the connection to your mining pool is interrupted, then Verify the network;
Referring on the test course of action document, the overall issues that occur are assembly procedure challenges and Manage board procedure challenges. Common troubles involve the inability to detect the IP, irregular number of detected supporters, and abnormal detected chain.
d-two) The 2nd case; the examination time is nearly two times as long as The great board (from time to time the worth of X will improve anytime you examination, and occasionally X=0); right now, the log ordinarily has the subsequent info (the crimson Get It Here variety is not really thirteen, based upon which seat the hashboard tester is linked to); over the take a look at, assume which the domain voltage of each of the fields in front of the irregular placement is almost under 0.
