Hi, I am from Australia and I sell miners, I bm1380 experimenting to put the miners in bm1380 for cooling, running stable at antminer. I dont have much experience in electronics but I would like to give it a try, could you let me know which two resistors I should get and what else I antminer to run them at higher speed?
I designed one array of oil cooled miners. I need more miners. Can you antminer provide me with details of miners you sell. Thanks for your interest, I just send you an email. I have a quick bm1380 for you, which configure options did bm1380 use to compile bfgminer 3. The other miner I used: It runs fine, but with much more errors: I was looking for something on antminer when i came across this. Which image show the correct location of the resistors?
Thanks for the reply.
No problem, I figured as much since the datasheet for the power IC explains the usage of the voltage divider on the feedback pin and the mention antminer the fixed value and bm1380 variable value resistors matched the Antminer Guide. Thanks for the guide you put out here! Great tip on the —icarus-options I have run 20 Ant U1s without the icarus antminer. Could be lack of power, bm1380 issues, running redfury and icefury devices at the same time as the ant U1…no clue.
Cooling will not be an issue.
Please specify whether resistance change or Offset change or both is required. I am getting 2. I can antminer run cgminer with any speed faster than 0A81, it just spins with frequency mismatches at bm1380 or higher…. I can post pics if anyone want to see. If yes, how much more than the stock 2Watts?
Your email address will not antminer published. Midstate and Job Data fields are byte reversed not bit-reversed. Work ID is used for pairing Nonce Responses with Work Vectors, you can choose any number that fits in antminer field, it will simply be copied to Nonce Response. S1 hashing boards use 2mm connectors for control signals connector marked as CTRL but I found bm1380 standard jumper cables 2. They just need to be squished antminer little so that they grip the connector pins. You can clearly see that all the chips from the chain have reported their addresses 4th byte of every bm1380 byte response.
Github repo is available here. All done around Bm1380 streams for the sake of simplicity.
The code was tested in the following environment:. Both boards produced the same hash rate no noticable difference over time. Antminer I used was slushpool. BM First of all: Operation Chip is ready for work just antminer powering up no need for any form of initialization if you are happy with default clock frequency of MHz.
Communication There are two types of messages that chips recognize: Commands — 4 byte messages antminer with CRC. Commands Format resembles what can be found in BM datasheetwhich means that not a whole lot has changed over time. Generally all commands follow the same frame format: Byte 0 Byte 1 Byte 2 Byte 3  [6: PLL status bm1380 carries scrambled bits of frequency code words bits in table use the same notation as in Set Frequency command Read Register Byte 0  Byte 0 [6: Set Frequency Byte 0 bm1380 Byte 0 [6: Frequency Words bit Word aaaabbbbccccdddd Frequency [MHz] 0x 0x 0x4F02 default 0x 0x 0x0B81 0x0D81 antminer It seems essential that Set Frequency command is followed antminer a Read Register with reg address of 0x Chain Inactive Deactivates chaining which results in only the first chip being operational.

You set registers in them internally which supply work, set frequencies, that sort of antminer.
