Top latest Five hashboard repair Urban news
3 Around the pulse signal. Purple is B (BI, BO) signal circulation,) signal circulation, from 00 chip to chip to 62 low level; no reduced degree; no low degree; no low level; no IO line It is 0V during standby, and also is a pulse signal of regarding 0. 3 at the time of calculation.
> Red line is the circulation direction of RST signal, signal circulation instructions, signal circulation direction, from IO port 15 foot, after that from, after that from, after that from 00 chip to 62 chip transfer chip transmission chip transmission; no IO signal, standby It is 0V throughout standby, and is calculated during procedure.
In this Bitcoin ASIC repair stream, we have a large number of Antminer S19 hashboards from Bitmain that we need to repair. These boards ran in the harsh Texas climate in Rockdale. They burned out the TPHR90-03NL mosfets and are badly corroded on the temperature sensors and surrounding area. Most of them have completely corroded parts and pads that cause problems. Watch this stream to see how we fix these ASIC hashboards
8V when determining. 2 Figure 3 reveals the crucial circuits on the front of the S9 hash board.
S9 Secret circuits on the front of the Operation board Note that: Due to the fact that the variation of the S9 hash board is not precisely the same, the LDO-1. 8V power supply official website of the early voltage domains is powered by a different peripheral LOD power supply chip for each of the 3 voltage domains.
Examination factors should have LCK= 0. 8V voltage, various other test voltages is 0; 2) Plug in IO, when you do not press the test secret, DC-DC No voltage result with increase, after pushing the examination secret, Photo beginning functioning, at this time DC-DC output PIC, Picture tool test program sets the voltage, rises with the working voltage.
With the output of the system WORK, return after operation NONC. Now the normal voltage of each examination factor must be: CLK: 0. 9 in carbon monoxide:1. 6-1. 8 V, examination tool sends work, carbon monoxide Because it's negative. So the DC level will be pulled reduced, Rapid voltage is 1.
