Review: All Politics Aside, This Is Why We Like the Antminer L3+

Review: All Politics Aside, This Is Why We Like the Antminer L3+

With Litecoin activating SegWit in a hail of fanfare, we thought it was a good time to review the most up-to-date Scrypt mining gear. Here, we take a look at Bitmain’s new Antminer L3+. We’re going to give you a raw review of this rig, focusing on pure performance — you won’t find any community drama here.

The L3+ is a four-board, nearly double-density step up from the L3 that came out a few months ago. Before the L3 entered the market, Innosillicon was the only company making a newer gen Scrypt ASIC with the A4. We will also review the A4 Dominator in the coming days.

The Antminer L3+ is a like all Bitmain miners: simple to use and powerful. The new design takes things a step further by using a four board setup with 288 chips.

Let’s take a look at the specs:

Antminer L3+ Specifications

  • Antminer L3+ ConnectionsHash Rate 504MH/s. A variation of +/- 5% is expected.
  • Power Consumption 800W +10% (at the wall, 794 during testing)
  • Power Efficiency 1.6J/MH +10% (at the wall)
  • DC Voltage Input 11.60 ~ 13.00V
  • Chip Type BM1485
  • Chip quantity per unit 288 chips on four hashing boards, 72 chips on one hashing board
  • Dimensions 352mm (l) x 130mm (w) x 187.5mm (h)
  • Operating temperature 0°C – 40°C

Antminer L3+ was provided by Bitmain and Bitmain Warranty to review along with the APW3+ PSU

Antminer L3+ LTC Mining Experience

The L3+ arrived packed safely with no issues. When you first see the L3+, you will notice the length and the dual fan setup, as well as its S9-type case. The design allows for the heat to be moved out quickly and efficiently.

Setup with the Bitmain APW3+ 1300 watt PSU is dead simple. However, one thing to note is that each board requires two 6-pin PCIe connections for eight total — plus one PCIe for the control board. If you don’t have an Antminer PSU, you need to make sure your unit supports that many connections.

The APW3+ has six pairs of PCIe connections, making it ideal for the L3+. The APW3+ is only 220v, though, and will not power up on 110v. If you need 110v support, you’ll have to buy the APW5 — which does 1300 watts on 110v and 2600 watts on 220v — or an equivalent PSU from another brand.

The Antminer console is the same as everyone is used to using. Most ship with DHCP enabled, so once you find the console’s corresponding IP address, you can login using the default root/root username and password. After you login for the first time, we suggest immediately changing your password.

The L3+ has a great Miner Config page where you can enter your pool info, as well as how you want the fans to run. There’s even a frequency adjustment panel for downclocking or overclocking. Overclocking voids the warranty so only do so at your risk. Whatever you decide to do with your clock speeds, you can use the miner status screen to monitor chip info, temps and speeds along with pool information for simple local management.

Antminer L3 Status

Overall, the Antminer L3+ runs like a beast. There is no other word to describe the performance, mainly because this rig has no direct at the time of this review. In our tests, we used Litecoinpool.org and Liteguardian.com for the pools. Recently, LTCRabbit and Clevermining — which we used to use for testing — shut down.

Antminer L3+ Offers Fast and Stable Litecoin Mining

The Antminer L3+ runs between 517 mh/s and 525 mh/s at both pools, rock solid. It does this while only pulling 790 watts to 794 watts at the wall. The default freq is 384 for testing and was very solid in its performance with no big fluctuations in performance. The ambient temp in the Bitsonline mining lab is 77 degrees Fahrenheit.

The L3+, like the S9, is loud — producing 94 dB at a distance of 4ft. This definitely isn’t a miner you will want in the room with you while you’re watching TV.

Antminer L3+ Poolside AvgLitecoin is having a resurgence in not only community attention during the last couple of months, but also in price. This rise is due to its activation of SegWit, a blockchain upgrade that has been the center of fierce debate in the Bitcoin community. Since Litecoin began moving towards SegWit activation, its price surged from the $4 average to over $30 per coin.

With SegWit locked in, companies have already made Lightning Network test transactions, and second-layer products have started emerging in the space.

That makes the Antminer L3+ a very good buy, as the chance for ROI at current value is not as far out depending on what you pay for electricity. We highly recommend the Antminer L3+ if you want to mine Scrypt algo coins like LTC. Between the hash rate to power consumption which is top in the class of miner to the solid build quality, it is something that will last quite a long time.

Bitsonline will publish our Innosillicon A4 Dominator LTC ASIC review in the coming days, so stay tuned.
