Link to official Antminer Manual: Next step is to modify antminer hardware and replace or add extar antminer. R1 and R2, see page 4 of the Antminer manual. Nice article, im following! I also ordered a antminer heatsinks for extra cooling them. Going to try overclock them too if you get good results with it. I actually freq the resistors: And as their list with rates goes up to 4, they might have considered their layout better, almost all components around the chip are taller, thus making the possibility of adding an extra heatshield much more difficult, cooling from just the rear of antminer д3 сколько майнит PCB is not enough.
Picture of how mine sort of looks like. I guess it should hash above 2. Hashrate can get higher, but cooling is the problem. The chip needs better cooling from topside. But also the dc-dc converter is getting hot. Fortunately that one has an over temperature protection. Follow freq steps below:. Toggle freq Awesome Miner. The default username is root and the default password is admin Awesome Miner will automatically detect if you are using S7, S9 or a mix, so in typical cases, leave the Auto detect feature enabled Specify the new frequency.
Please note that the currently listed frequency may not be what your Antminer is using right now. Click OK to apply changes to all selected Antminers The Antminers will be freq after the changes have been applied, and will for that reason appear as Disconnected in Awesome Miner for antminer short period of time.
To be able to take the Antminer U1 past 2. Antminer U1 Image above shows location of resistors and values of replacement resistors.
Once the resistors are replaced you can change the frequency hex to options on table 2. Stay tuned for a whole lot more at coinreport.
Click for image Click for featured image. Is it antminer to overclock it in the UI of mulitminer or does it need to be done in bfgminer command? This time, I need give my S1 a minor operation,in order to let it work for another 3 freq. Modify some resistance to reduce chip voltage and frequency. Avalon4 28nm bitcoin miner Update. Last updated on Sep 19, at Based on freq following values:. Comparison of antminer mining pools on the official Bitcoin wiki. I run small, outdated miners at a loss pointed at a P2Pool node antminer I like to do so. Antminer T9 - Bitmain-freq self. I can ssh into the miner and I have located the config file that has the bitmain-freq and bitmain-voltage but I am having trouble finding references to "safe" or tested chip frequencies.
The first board This is the reason I am looking into modifying the frequency. Is it any quieter than the S? I doubt freq Its pretty loud.
