Yesterday we have now revealed our First Arms-On Expertise with the Jasminer X4 1U Ethash-Etchash ASIC Miner and as we speak we’re persevering with with some helpful details about the machine for anybody that may personal it already or plans to get a Jasminer X4 to play with. As we’ve already talked about this ASIC miner for Ethash and ETChash is kind of simple to work with each by way of {hardware} and by way of software program because it just about modular by way of {hardware} and with open root SSH entry to the software program data on the machine. So, as we speak it will likely be extra in regards to the software program and what you are able to do with the intention to tweak or mess around with the miner to optimize it extra, or possibly overcome some missing function and many others.
The Jasminer X4 1U Ethash-Etchash ASIC miner comes with two choices for configuring and working the miner – a web-based interface and a software program instrument for Home windows solely. Each function fairly primary settings solely – mining pool settings (as much as 3), what algorithm/coin to mine (ETH/ETC) in addition to the working frequency of the miner (200 or 225 MHz). The remainder is dealt with mechanically or set to a predefined worth, thus type of limiting what’s consumer accessible and making you consider some workarounds in case you want one thing particular. We really had a number of to work with and have discovered an answer, although it might have been nicer if there was a bit extra consumer management out there… a complicated settings web page within the net interface possibly. Oh, wait, there really is one, however it’s hidden and never absolutely functioning (superior.html) within the newest firmware.
Within the superior management web page in addition to the 200 and 225 MHz working frequency there’s additionally an choice to allow 250 MHz as nicely, then there’s additionally an choice for fan management out there (Auto and Handbook modes) and there’s additionally an “Operation Mode” that may be both Excessive-efficiency, Steadiness or Excessive-performance (undecided what these really do). However even in case you work round these settings attempting to set them doesn’t work apparently as there are different measures set to type of restrict your entry or the options won’t be correctly carried out in any respect… undecided which one it’s. We’ll get again to those in a second with some extra particulars.
The sl_miner management software program that’s solely out there for Home windows working methods has just about the identical settings for the miner, plus a straightforward choice to scan an IP vary to see what’s the IP tackle of your miner generated by the DHCP server, to be able to entry its net interface. This software program makes it simple to configure and monitor your miner from a single window and what it does higher than the Internet-based management panel is making it simpler to manage a number of Jasminer X4 miners that you just may need. With the sl_miner software program you don’t should open totally different web-based management interfaces for every of the miners when you have a couple of that’s.
Now, bear in mind that when you boot up the Jasminer X4 miner it could appear to be idle and never working for some time or in any respect. You will have to have some persistence because the machine wants about 20 minutes of time with the intention to generate the DAG file earlier than it might really begin mining, so be simple on the reboots or config adjustments that can require you to restart the miner. The excellent news is that altering pool settings and working frequency of the miner doesn’t want a reboot of the system, altering the algorithm you utilize nevertheless does.
In case you are feeling adventurous you may login onto the Jasminer X4 management board over SSH with putty or one other such consumer and discover the machine on the software program facet. The default username is root and the password can be root and you might be prepared to start out trying round. The miner software program known as Jasminer and is model 2.05 within the newest firmware and to make issues a bit simpler for you we have now proven the checklist of instructions supported by the miner. Many of the issues right here aren’t a lot of an curiosity, aside from the choice to set the fan pace and to alter the working frequency of the machine. Discover that on the screenshot it says JasMiner-Brick 2.05 and there’s a motive for that though we’re utilizing the Jasminer X4 1U right here, however extra on that in a second.
Do be aware that the jasminer miner software program is executed and working as quickly because the machine begins and there’s a monitoring script that can restart it if it senses that the miner has stopped for some motive. So, simply issuing a “killall -9 jasminer || true” command (with out the quotes) will cease the miner for a second after which it’s going to begin again once more, that you must additionally cease the monitoring script with the intention to manually run jasminer with your personal settings. For stopping the monitoring script as nicely you’ll need the next command “killall -9 monitor || true“, do be aware that it might be smart to start out it afterwards or reboot the miner to mechanically revert issues in addition to the config file.
By default, the miner runs with a config file that’s being created and adjusted from the online interface or the sl_miner software program, the precise command line that’s used to start out it’s as follows:
jasminer –version-file /and many others/machine –config /media/configs/jasminer.json –syslog
Contained in the config file you solely have the pool data, the algorithm and working frequency together with some API information. There is no such thing as a choice to manually management the fan pace from the config file, that you must run the miner with the “–fan_speed” set to the proportion worth you need and that may be an issue if you wish to do it completely. The configuration file is saved on the reminiscence of the machine, however the remainder of the software program is loaded into reminiscence from a bootable picture, so no everlasting adjustments might be saved and out there if you reboot the machine sadly.
So, guide fan management might be robust problem to cope with the Jasminer X4. The automated mode energetic by default apparently follows the temperature and adjusts, however you would possibly simply need to have the followers working at 100% on a regular basis for example. Otherwise you would possibly need to modify the miner with extra highly effective followers and run them at decrease RPM to make them silent whereas nonetheless offering greater than satisfactory cooling for the ASIC chips. There are some doable workarounds right here that may allow you to do issues like that, however they’ll most certainly not be everlasting and can have to be reapplied after a reboot as a result of approach the machine operates.
One factor which you could completely do with the intention to have the followers working at most RPM is to depart solely the ability pins of the cooling followers related to the miner’s management board. That nevertheless will current you with one other problem – no reporting of FAN RPM to the software program and it will set off a security measure that can forestall the machine from mining. It can nonetheless run and calculate a DAG, however as quickly because it wants to start out hashing it’s going to simply not begin as it’s going to assume that the followers aren’t working and it’ll overheat if it begins mining. You’ll find yourself in the identical state of affairs if you’re fascinated with some various cooling strategies as nicely resembling immersion cooling the place you won’t want to attach any cooling followers in any respect. Getting followers reported at zero RPM will set off a failsafe mechanism that can forestall the miner from beginning to hash… there’s a straightforward answer for that as nicely.
We’ve remembered that there’s a smaller Jasminer X4 Brick miner that has a decrease hashrate and is totally passively cooled, so why not flash the firmware of that miner (sure, it’s going to work on the X4 1U as nicely) and eliminate the annoying fan security measure. Do not forget that this miner doesn’t have followers, so no an alarm firing when followers are reporting zero RPM… they do it anyway as no followers are related there within the first place. The miner will nevertheless run any followers related to the management board simply effective, it’s going to simply not forestall you from mining as there is no such thing as a fan failure detecting mechanism out there on this model of the miner.
There’s a small catch nevertheless, by default the web-based interface for firmware upgrades will refuse you to flash the firmware for the X4 Brick, the one factor that you must do is simply rename the unique file you obtain from the Jasminer’s web site from JasMiner-X4-Brick-20220726-183045.tar.gz to JasMiner-X4-20220726-183045.tar.gz after which it is possible for you to to flash the X4 Brick firmware onto your X4 1U simply effective. Efficiency and have smart we see no distinction with the X4 Brick firmware in comparison with the unique X4 1U one aside from the dearth of fan failure mechanism in place and the truth that only a single working temperature is being reported by the machine and never a spread.
Thus far, so good. However what about working the miner at a better frequency with the intention to enhance the mining efficiency? By default, you’ve gotten solely 200 MHz and 225 MHz out there, however you can too make the miner run completely at 250 MHz with somewhat taking part in round. You simply have to SSH to the miner, go to the /media/configs folder and edit the jasminer.json configuration file altering the freq setting to 250. Notice that this can be a semi-permanent setting change, that means that it’ll stay in place after rebooting the miner, however might be overwritten as quickly as you alter the mining pool for example. You’ll merely have to redo the change once more with the intention to have the miner boot at 250 MHz working frequency.
Evidently this setting is perhaps eliminated as an out there choice on account of the truth that it may be an issue for lots of even the entire Jasminer X4 to function correctly at that setting with their default setup. In our case the machine does produce approach too many errors and in consequence solely about 50 MH/s hashrate is being reported as a substitute of getting greater than 10 instances increased efficiency. You’re welcome to try to report if it really works for you any higher or not and if it does what hashrate are you getting. It is perhaps an issue of correct cooling, or the 300W energy provide not being sufficient or just because the chips aren’t Pleased with the upper frequency.
Anyway, beneath you’ll find a fast checklist of the three working frequencies of the miner with the ability utilization measured on the wall and a hashrate that’s anticipated at that setting. Do be aware that the ability utilization reported is with our silent modification to the miner utilized and that lowers the precise energy used as in comparison with the unique cooling setup:
200 MHz – 237W – 450 MH/s+225 MHz – 265W – 520 MH/s+250 MHz – 294W – ~50 MH/s
The Jasminer X4 1U does handle to work simply effective at 225 MHz producing over 520 MH/s of hashrate secure and downside free, so that’s the advisable working frequency of the machine with the intention to maximize efficiency. If the 250 MHz setting works for you issues is perhaps higher, however not all or any would possibly do. If not working correctly on the increased working frequency you may be getting a lot decrease hashrate than anticipated with increased energy utilization because the miner is definitely working, however producing a whole lot of errors and never correctly hashing more often than not.
Few extra issues that we already talked about within the earlier article, however that have to be talked about right here as nicely for those who don’t see each posts. The entire lineup of Jasminer X4 ASIC miners comes outfitted with 5 Gigavbytes of reminiscence, so in addition to the machine not usable for Ethereum mining anymore (as a result of current change from PoW to PoS for that one), you will be unable to mine ETHF or ETHW or another fork that break up off Ethereum on the Merge that occurred final month. These have already got handed a DAG dimension that may match contained in the reminiscence (you may mine them with a decrease hashrate for some time), so take into consideration mining youthful Ethash cash with smaller DAG dimension than 5GB or ETChash ones resembling Ethereum Basic.
Additionally, at present the Jasminer X4 product lineup doesn’t help dual-mining of ETC/ETC coin with ZIL, one thing that might enhance the profitability of the mining {hardware} simply with 30-40%. Sadly, not supported for the second and the identical goes for utilizing the Jasminer X4 on the Nicehash mining platform the place you may additionally goal for increased revenue than simply mining ETC. Nicehash shouldn’t be at present supported and the miner shouldn’t be connecting to any of the swimming pools on the platform for the time being, although a future compatibility replace including help for these two issues could be a pleasant addition.
We do hope that this additional data and ideas might be of use and allow you to get extra out of your Jasminer X4 1U ASI miner and in case you do have some questions be happy to ask. We’re going to proceed taking part in with this miner for some time for certain and can report extra about it afterward, hopefully together with excellent news relating to improved or added options. In the meantime subsequent we’re going to goal our consideration to a competitor of Jasminer X4 – the iPollo vary of ASIC miners which were on our radar for some time now too.
