First Impressions From the New Lower Power Usage ZeusMiner Scrypt ASICs

Earlier this month ZeusMiner has announced their next generation of Scrypt ASIC miners (X6) that are supposed to use less power than the previously available X3 miners. Thanks to MinerEU, an official ZeusMiner partner, today we have received three out of the four new X6 miners and have decided to share our first impressions with more to follow in the next few days along with detailed reviews of the Zeus Lightning X6, Zeus Thunder X6 and the Zeus Hurricane X6 with a Zeus Blizzard X6 still on the way.

If you have been following the development of the ZeusMiner Scrypt ASICs you will probably notice that the new X6 miners are essentially almost the same as the previous generation, just running at lower voltage and operating frequency of the chips in order to use less power and sill provide good hashrate. That, along with new lower prices, actually does make the new ZeusMiner X6 Scrypt ASICs really interesting miners to invest in even with the current market conditions. The new ZeusMiner X6 Scrypt ASIC miners with lowered power usage and prices in fact may offer you one of the quickest return of investment, so if you were considering investing in a Scrypt ASIC, then you should definitely do some profit calculations. Of course nobody can predict the increase in network difficulty or the fluctuations in the price, but if things remain stable you might be looking at less than 2 months to break even if mining Litecoins.

So what is different with the new ZeusMiner X6 Scrypt ASICs? They do come in the same boxes and use the same chips, however the difference is that the chips are now running at lower voltage and operating frequency. The result you get is lower power consumption and still a good hashrate, without pushing the chips close to their limits. We have opened up the new Thunder X6 to see that it is pretty much the same picture as we’ve seen with the previous miners. Each board has the same number of chips, we did notice a sticker that says 1.1V on the board, so this is probably the new operating voltage (down from 1.2-1.3V). There is also one less power mosfet on the board for each of the power blocks, probably removed as a result of the lowered power consumption. This however does mean that you might not be able to play much with overvolting the new units by replacing resistors or at least the headroom for that will not be much.

We could not find an official or recommended operating frequency for the new X6 miners, but we already knew that it will be lower than the sweet spot of about 328 MHz. So we’ve started going down and it seems that the new sweet spots in terms of operating frequencies for the lower power units are somewhere in between 235 and 250 MHz. This is the range where we get hashrate close to what is being advertised and at the same time the HW error level remains low, though we are going to play some more with the frequencies to narrow down what works best with the default setup and with no hardware modifications. So far we are happy with what we are seeing from the new ZeusMiner X6 Scrypt ASICs and you can expect more as we continue using and testing the units in the following days.

Good friend, I saw the price at $ 940 minereu.com and the price on the website of Zeus is $ 2,199. I find it odd that much difference in price. To what is this? Thanks

MinerEU are selling just the new miners alone and Zeus is “giving you a bonus” an older gen miner along with the new one, but you are essentially paying for the second miner and the shipping cost is higher for the two miners… so not that great of a deal, but they need to clear old stock and probably figured this is a good way to do it.

Ok, I understand, Thanks for the explanation.

If i understand ur article correctly, you are basically saying its the same chip but just under clock?
that properly explains why its clock lower then the first gen model.

Would be interesting to see if current gen A can be underclock?

tonyc, it is not only the clock frequency, but also the chip operating voltage lowered on the new miners. On the older miners you can lower the clocks, but the voltage is not user controllable, it will require some hardware modifications, so unless you do the hardware mod the power consumption will not change much. Increasing the voltage could be problematic on the new miners as they also have a power mosfet removed compared to the older miners power block design, so the new design will not be able to handle much of an increase of the voltage.

Are you guys using cgminer or bfgminer? Could you show me your config settings? I recently just received my new Thunder x6 with the lower power consumption but as soon as i set the frequency over 195 the machine just shuts off instantly. (where as you guys say you can get between 235 and 250)

Armani, we are using the official cgminer. In your case the problem might be the PSU, what power supply are you using?

I’m using a SeaSonic 1250w PSU.

Oh, sorry, it’s a Lightning x6, not a Thunder x6, will that make a difference in frequency?

That Seasonic should handle the power requirements of the Lightning X6 just fine, we have finished testing the power consumption of the new bigger X6 miners, you can check here – http://cryptomining-blog.com/3184-checking-the-power-usage-of-the-new-zeusminer-scrypt-asic-miners/

If you have a power meter you might want to check the power usage at the wall just to be sure, but it could be some sort of power supply protection kicking it… Make sure to connect separate PCI-E lane to all of the connectors on the miner, do not use two PCI-E power connectors on a single lane/cable as this can cause an overload of the line.
