I got my 2nd batch of z9 mini today. None of the 4 miner from this batch can hold 700 mhz clock, they can do 650mhz at 14.1k sol/s. Still fine tuning them for max hash rate.
2 miner from the first batch easily does 750mhz, 16k sol/s.
They are probably sorting chips for mini vs full size z9. That is common for other chip makers and helps explain variation in batch one hashrate. Unfortunate for batch two buyers on all fronts, it seems. The Mini and full have same chips, it appears, and same rated MHz/performance. So not much need to sort the chips for either. Not all chips in a batch are created equally. They pick the best ones for higher end products like the non mini which require a higher stock clock speed. This is called silicon binning. Only that the manual of the non mini says it’s also clocked at 500. Interesting. Does this mean the non mini has 4-5x the amount of hashboards then? Based on how well the batch 1 minis OC I would think the non mini should be able to hit 50k with just 2-3x the hashboards. It has 4 times the hashboards. That makes me think it can be at least overclocked to hash at 60. |

I am curious if you can reduce the speed of the fans when using 2 and keep the temps low? That would reduce the noise level.

Has anybody be charged with customs when just receiving one miner at a time? I feel that there must be a value threshold where the customs fee applies and just one z9 mini (especially with coupon) is below that.

Does that work if the miner resets or powers up again? Do you have to type it all in again?
Once you do it, the "value" of the option you modified is written to the configuration files. It stays permanent untill you change frequency again or reinstall the firmware. <option value="750"> 750M </option> The value="750" field is the one that's written to the config files. The "750M" is simply what is displayed and does not matter. I get hardware errors on both my batch 2 units @ 750. For me one hashboard just stops hashing if I go above 675. No hardware errors, just no hash. |

Z9 Manual has been posted: https://service.bitmain.com/support/download?product=Antminer%20Z9The Z9 Mini is 3 hash boards, 36 ASICs total, 10K Sol/s spec'd. The Z9 is 3 hash boards, 48 ASICs total, 42K Sol/s spec'd. So, different ASICs on the Z9s than the mini's if the manual is to be believed. Hmmm... I bought the Z9s hoping/planning on similar OC to the mini's. "Uh Oh." It's interesting that the Z9 Mini has 36 ASIC's total - the Miner Status screen shows only 12... 4 per board. I always thought that was the actual physical number of ASIC's/FPGA's on each board. Something doesn't add up. I'm an idiot is what is up. I've got 12 Z9 minis running and awesomeminer was showing me the summary of 36.. 3 hash boards per-unit. .... Take #2 1 Z9 Mini has 12 ASICs, 10KSol/12 = 0.83KSol/ASIC 1 Z9 has 48 ASICs, 42KSol/48 = 0.88KSol/ASIC So yeah.. probably the same chip, and maybe binned on the production line. This would be good news for big Z9 buyers. 1 Z9 = 4 Z9 Mini. I expected it more like 3 Minis. This makes me believe the big one should hash at about 60KSols with overclock. |

Would make sense from a production perspective. |

Shoot! I was hoping to save on the price of an additional PSU. My miners arrive between 5-15 Sep so I'll try hooking them up and update this thread here then.
Maybe what seems theoretically all right is not possible practically for whatever reason.
You can power 3 as long as you don't overclock any of them. But why? Overclocked each takes a max of 450w - that's a maximum of 1350w total. Some of my S9's running off the same type of supply consume up to 1450w. I'm curious as to what the difference is that's all. Edit: It's to be noted here that I'm using a 240v circuit for my power supply. On 110v the supply can only generate up to 1200w of power but on a 240v it can do 1600w. Maybe this is the reason for the discrepancy reported here? Oh I thought you were running 110v. With 240V you should be able to. |

How did you mount the fan?

What kind of fan did you use? Did the noise level decrease?

I just got a text message from UPS about import duties. I am in Texas, USA.
The are charging me 367.87 !!!!
This is the breakdown:
IMPORT CHARGES
NOTE: the total value used for calculation of all Duty-based fees is 0.00.
Government Charges: 356.87
Brokerage Charges: 11.00
Freight Charges: 0.00
356.87 / 1400 (2 Z9 minis at $600 each + shipping fees) = about 25%
Looks like US folks are getting hit with the new Trump tariffs on Chinese goods.
Ugh. Is anyone facing the same issue?
Same in NJ. That's fucked. Does it say anything on the UPS tracking page? UPS doesn't have my info to text me about it but the tracking says I should receive mine today. The batch 1 miner had something like a $60 fee but it mentioned a fee being due on the UPS tracking page, although not the amount. This one does not mention a fee on the tracking page so I am hoping I dodged it. Did you order one or multiple? Maybe 1 is below the threshold where the customs fee is applied? I ordered 2 with DHL and I had no import fees. Weird that just using a different company gets you out of paying those fees. Interesting. I have one coming tomorrow with DHL and one on Thursday with UPS. I am curious now how many fees I will have to pay. |

Do you accept local pickup and payment in cash? |

How well do the GPUs hash stably? Do you have the receipt, that you could provide for warranty purposes?

Are you only using radial fan cards in your setups (founders edition) or also third party designs? |

Thanks! I am also using EVGA 1600 T2. How many 1089TIs can I run from it? I was planning on 7 maybe 8?
8 will work but the first slot has limited card length due to that mobo connector. The zotac 1080ti mini fits, but I think any other 1080ti is too long. Here's my setup: https://imgur.com/a/hivgREjI use that last slot as a cable compartment.  Looks great! Thanks. I was planning to maybe put a 1070/60 in slot 1. Where did you get that case? Looks nice . I am building my own, since I had aluminum extrusions laying around and a 3D printer (and if I decide to switch to a different mobi it’s no problem since all the standoffs are flexible) , but I am curious how much they are. |

Does anybody know how much power the Onda boards draw through the Sata/Molex connectors? Should each of the ports be connected separately from a separate port? I am building two of these rigs with components from Philipma (thanks again for the good prices!). Just waiting for the acrylic order to come in. My plan is to close all sides with acrylic that I am gonna laser cut and have space for 4x140 mm fan in back and 4x120mm fans in front. Will be my tidiest rigs and “wife friendly”. Just need to decide which GPUs to put in. (The one shown is just to test fit. It’s super old 😆)  |
