Antminer Z9 mini overclocked

[Hitsxx]

Those batch1 or something else?

It is possible to overclock any batch.

Do tell. What hardware modifications made?
I've no problem pulling these outta the factory chassis and modding...

yes I know, my question was about the hardware change and not how to set 900 on frequency.

On the right is the original hash panel. Left - changed.

The bottom line is that the chips should get extra power.
Detailed step-by-step instructions from me will not be, as long as I make money on these changes. Excuse me. My message was for those professionals who work with electronics. These people know that this is possible and how.

I see -- thank you. Did you make any cooling changes? That is my current limitation of knowledge -- thermodynamics is more of a challenge than the electronics aspect. I'm trying to simultaneously optimize cooling on basically 24 Z9 minis.

At these capacities, cooling optimization is not required. And there is no good possibility. In the initial system, the optimization depends on the ratio of the area of ​​the crystal and the volume of the surface of the radiator.

But we will experiment with liquid cooling and increase the speed to 25 kSol (or higher).

Can you do the same to batch 2 Z9 Mini's ? 20 sols?

Of course we can. But there is a problem - the devices must come to us.

Where are you located
what is the cost per unit?.
And what is the turnaround time?.
Thanks

Any package is overclocked. But this is not an easy decision.

That is a great OC Hitsxx, wish i had the skill/Knowledge to undertake that kind of up grade. you do this as a business??

Thank you for your price quotation for the upgrading the Z9's Mini's.. but that price is too much in my humble opinion.  plus this is a sharing forum where we share and help each other out for free where possible as a community.
Good luck with your venture.

Price - the concept is very conditional. This is justified at a time when it is beneficial to both parties.
About the forum - completely agree with you, with one exception. Here people help each other to earn money (here 90% of participants do not play the game, but discuss ways to earn money). And my proposal is not so different. I help to earn you, and you to me. All is correct - an honest exchange.

Is all that is needed to achieve this is add the 4 components? (For which there are already pads)?

Of course not. The installation of visible components in the photo is only part of the necessary work.

Unfortunately, at the moment I am limited to the rules of the forum on the number of responses to private messages. If you need a quick reply, write an e-mail.

I need some help I flashed the firmware of my second batch and I want to restore it.. how to do? On the bitmain website there is only the may version... I think that the old version gives some issues with the batch 2 ...

I installed the old one simply to 2nd batch which had Aug version of firmware.
and it works well and Freq can be changed correctly.

Ship to a newbie? Thanks but no thanks. No way I'd ship to anyone but a community vetted long term member even if @Hitsxx did it for free. Happy with my puny 15.5 Mh/s. Besides, it's just a matter of time before one of the more knowledgeable, experienced and long term (not to mention generous and community oriented) members in this forum post details of the mod anyways. If it even works stably - which is just a claim at this point in time. A couple pictures is all that @Hitsxx has to prove it.

Agreed, my thoughts exactly  We will get there by ourselves as a community, we sort and fix everything together

What issues

Tried factory reset???
