Mining
The Jasminer collection of ASIC miners for Ethash and ETChash by the Chinese language firm SUNLUNE have been fairly massive (and costly) once they have been introduced close to the top of final 12 months. They have been probably the most environment friendly Ethereum ASIC miners on the market on the time and with the excessive mining profitability of ETH on the time there was curiosity and demand even being fairly costly miners. Now, with the top of Ethereum’s mining part and the low profitability of mining for just about every little thing the Jasminer ASIC miners are simpler to come up with and you might get a good deal for the worth of 1. The massive query nonetheless is must you put money into a Jasminer X4 ASIC miner now and that’s exactly what we’re going to discuss right here.
We’ve managed to attain a good deal for about $2000 USD on a Jasminer X4 1U-C ASIC miner as we have been attempting to get our fingers on considered one of these for some time now to mess around with it and see what the hype is all about and share our first-hand expertise from the system. So, under you will see that a few of the issues we’ve seen taking part in for just a few days with the system in addition to some helpful ideas and tips which may assist any of you which may have already got an X4 miner or are possibly planning to purchase one. One of many very first thing we like to do is to open up the {hardware} and discover what we’ve inside and the way we will enhance it additional or optimize it, then mess around with the software program as nicely to see what else could also be lingering in there too. However we are going to get to that in a bit, for now allow us to simply share our first fingers on expertise with the system…
Jasminer X4 1U is rated at 520 MH/s with an influence utilization of 240 Watts (with 10% variation in keeping with the specs) with an influence effectivity of 0.46 J per Megahash or hashrate. The system is supplied with 8x Jasminer X4 ASIC chips in a forty five×45 mm measurement (678 sq. millimetres die measurement) with 1TB reminiscence bandwidth, 5GB of reminiscence and a hashrate per chip of 65 MH/s. Every of the chips has 384 computing cores and 384 on-chip dies in keeping with the producer with a 512-bit bus width and an working frequency of 800 to 1 GHz and an influence consumption of 23 Watts. The 8 ASIC chips are positioned on a single board with a controller within the center and there’s additionally a separate controller board, an influence provide and quite a few followers contained in the case.
The Jasminer X4 1U-C that we obtained is just about the identical because the Jasminer X4 1U mannequin, nonetheless it’s rated to 450 MH/s with 240 Watts of energy utilization as a substitute of 520 MH/s with the identical energy consumption. We aren’t solely certain if there’s truly a {hardware} distinction between the 2 items or it’s extra a matter of software program and extra particularly the clock charge of the chips 200 MHz clock for the X4 1U-C and 225 MHz clock for the X4 1U and that is one thing you’ll be able to management from the miner configuration (the 800 MHz to 1GHz specs of the chip). Shouldn’t this nonetheless imply that these chips ought to be capable to run at 250 MHz as nicely then, nicely, it does, however you aren’t allowed to do it by default, although you’ll be able to learn the way to do it your self under.
The mining system is available in an ordinary 1U server case, so it’s straightforward to deploy in a rack and be utilized in a goal=”_blank” rel=”noopener”>
Contained in the 1U miner case there are 9 small server AVC followers which can be usually very noisy as a result of excessive RPM that they function at. The actual mannequin is AVC DBTB0428B2U, with a measurement of 40x40x28mm, twin ball-bearing and rated at 12V 0.48A (5.76W at most pace of rotation). They’re PWM controllable 4 wire followers and though they begin with low RPM and never that a lot of a noise, as quickly as hashing begins they up their rotation rather a lot and change into very noisy and energy hungry… at max RPM these might rise up to nearly 52W of energy utilization only for the followers. Modifying the miner with fewer bigger followers could make it not solely extra energy environment friendly, however nearly silent by way of operation.
Even if you happen to cease and change the 9 cooling followers for the ASIC chips there’s another factor you could take motion on. The ability provide can be a server kind one and although it’s wated at simply 300 Watts it does include yet one more small and noisy fan that though not as loud because the others nonetheless makes the miner noisy when working. You will have the choice to both change the usual PSU with a silent one (you solely want 3x 12V 6-pin PCI-E energy connectors to energy every little thing) or disconnect the small PSU fan and change it with a bigger silent one.
One of many first issues we did with the system was to make it silent, which means that we disconnected all the 10 noisy server-type followers and have changed them with 5x Arctic Cooling F12 120mm followers (rated at 12V 0.21A), making the Jasminer X4 1U-C run just about silent. The principle Jasminer management board has 2x 4-pin fan sockets that you would be able to make the most of (every of them has a splitter board linked for the small server followers). So, you’ll be able to have 4 followers on the primary heatsink the place the ASIC chips are linked by way of a 4-fan splitter cable to the primary socket and a single fifth fan linked to the second socket. You could both have followers linked or a fan simulator as if no RPM is being reported an alarm will set off. You’ll have to open the ability provide and disconnect its fan from the PSU major board (there could be some glue on high of the connector to carry it in place), or simply use a unique silent PSU altogether.
It’s fascinating to notice that the primary management board of the miner has three sockets for ASIC miner boards to be linked and only one is getting used within the X4 1U miner, however the different two slots are absolutely practical, so if you happen to add a second and a 3rd ASIC board they need to be energetic as nicely making the miner 1040 MH/s (Jasminer X4-Q anybody?) or 1560 MH/s respectively. Essentially the most highly effective mannequin with 2500 MH/s Ethash ASIC hashrate – Jasminer X4 Excessive throughput server that the corporate sells might be outfitted with a unique management board with 5x 8-chip ASIC boards. So, you probably have a number of X4 1U items you might mess around and switch them into fewer miners with as much as 3 computing boards per management board and extra highly effective 800 or 1000W energy provide.
So, allow us to get to mining efficiency and energy utilization that we’ve measured. First is inventory settings the place we’re utilizing the default {hardware} configuration of the system (simply because it got here) working at a clock frequency of 225 MHz after which the identical settings with our silent modification described above.
Default
– 225 MHz clock
– 297 Watts of energy utilization
– 55-61 C ASIC temperature
– 530-560 MH/s hashrate common
– 76 Decibels noise stage (dBA)
Silent Mod
– 225 MHz clock
– 265 Watts of energy utilization
– 53-56 C ASIC temperature
– 530-560 MH/s hashrate common
– 44 Decibels noise stage (dBA)
The official mining profitability calculator on Jasminer’s web site experiences round $1.25 USD day by day revenue for the Jasminer X4 1U system mining ETC in the mean time, however that’s with energy value of simply $0.05 USD per kWh and most of you’re most likely paying at the least a number of instances that worth. With a mean worth of round 25 cents per kilowatt hour of electrical energy you’re nearly to have the ability to pay for the electrical energy utilized by the miner in the mean time. The above calculation is made utilizing simply Ethereum Traditional (ETC) mining and no dual-mining or Nicehash with ETChash mining which can be more likely to be extra worthwhile in the mean time with 30-40% greater earnings on common.
Sadly with the Jasminer X4 for now at the least there is no such thing as a choice to dual-mine ETC + ZIL on a mining pool like Ezil.me as a result of approach the miner works (it splits the pool ID on the first dot threating the remaining knowledge as a employee ID, so you can not have two wallets in it for ETC and ZIL). It’s not solely an issue with the Ezil.me mining pool, the opposite greater ZIL twin mining choice K1Pool makes use of a single ID for pool username, so you’ll be able to join the Jasminer X4 to it and it’ll mine ETC, however when it wants to change to ZIL mining the miner will merely idle for some time after which proceed with ETC mining when it’s resumed. So, dual-mining ETC+ZIL just isn’t working for the second with the newest official firmware for the Jasminer X4.
The choice greater paying choice is ETCHash mining on Nicehash that experiences greater profitability most likely as a consequence of individuals utilizing it for purchasing hashrate to double mine ETC+ZIL. Now, we all know that miner has bother with direct dual-mining, nevertheless it additionally has one other problem – it’s presently not appropriate with Nicehash in any respect. The miner experiences any of the Nicehash DaggerHashimoto and ETChash swimming pools as lifeless and doesn’t connect with them in any respect and we’ve confirmed with the producer that Jasminer X4 presently doesn’t have Nicehash assist. So, sadly not a lot you are able to do right here to get some additional mining revenue for now with dual-mining ETC+ZIL or NiceHash mining, the primary competitor iPollo has apparently launched an up to date firmware for his or her ASIC units that helps dual-mining, although we’ve not personally confirmed.
So, what’s the conclusion that we will come up primarily based on our first impressions from taking part in round with the Jasminer X4 1U ASIC Miner. We are able to clearly say that the Jasminer X4 1U ASIC miner is a pleasant piece of {hardware} that’s constructed nicely. The hashrate and energy effectivity are actually good and with one thing worthwhile to mine it’s actually a pleasant ASIC miner for Ethash and Etchash to have helpful to mine. The Jasminer X4 1U system is meant to be used in>it’s not a good suggestion to make use of it as a house heater (until you make it silent, however nonetheless with lower than 300W of energy utilization not a lot of usable warmth generated for the winter).
If in case you have some additional questions in regards to the Jasminer X4 1U ASIC miner be at liberty to ask and if we will we’re going to attempt to assist.
