The bitaxeSupra: Open source Bitcoin miner based on the BM1368 ASIC

a picture has appeared on twitter showing the new bitaxeSupra with a mining performance of 1.2 th/s
unfortunately it is not known which cooling and how the bitaxeSupra has been modified

It’s unlikely that’s the sustained hashrate. In fact, D-Central the company that made this unit says the following;

Beautiful shot! Give it time, it will normalize the hashrate haha, but some of them can maintain 800GH/s. Very impressed with the BM1368 chips so far.

I have 5x 401’s right now.  I’ve had a few of those big 1.2-1.4th but 3 of the 5 hover above 820-850gh and the other 2 are all in the high 700s (780-790). 625MHz and 1250 for voltage.

Hey cygan, thanks for the shout out! It's true the new Bitaxe is called the bitaxeSupra and it features the BM1368, the ASIC from the S21.

As some people have mentioned, it's hard to get the chips right now, because it's so new. I'm sure that will change soon enough. This is exactly how things went for the BM1366 from the S19XP.

The bitaxeHex development continues with the BM1366 for now, because of chip availability and the fact that some work still remains on the BM1368 protocol.

As always, check out the OSMU Discord for more! Invite link at bitaxe.org

Hey Skot, thanks for your great contribution to bring back open source to bitcoin mining! I just bought 2 supras and already hit a best share of almost 1B.  
I'm soon going to build two further ones myself. Getting closer to the 1.000.000 mark...

i can now also count myself among the bitaxe community
since yesterday i have been running a Qaxe+, which is operated with 4 1368 chips and controlled via the raspberry pi

so far i am very satisfied with the design, the very good manufacturing and of course the hash performance

Where to buy (in EU)?

i've been able to get ~1.1 TH stable on my single chip bitaxe supra, been running it over a week with no issues. def not with the stock PSU though, i got a 5V switching power supply off amazon. nothing fancy for cooling. literally just an extra arctic USB fan pointed at it.

settings:
850 Mhz
1350 core voltage
Temps: 65-68° C
Power: 27W-30W (not including extra fan)

Ambient/Room Temp: 70-80° F

pretty sick ngl. was also able to take a bitaxe ultra to over 700 GH with similar settings.
