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??
Just checked the Bitmain site, and they have reduced the cost of the Z9 and Z9 mini!!!!
Z9 down to $3091Ships late Sept
Z9 Mini down to $793 Ships late Sept
Wonder if they can't sell them?
I wouldn't rush into ant more Z9 Minis.. I think wait and see if the big boy will OC Z9 down to $3091Ships late Sept

I am a bit stuck for which coin to mine... Looking for best returns consistently
1 Autoswitch on MPH?
2 Zclassic on MPH?
3 Zec on Antpool?
4 Zen on Prohash? or MPH?
5 Zec on Slushpool?
I love the idea of auto switching, if you decide to go that way PLEASE PM me again with a idiots guide on how to...... (Like you did last time). Really very many thanks!
DOH! gonna need a complete idiots guide, just tried to follow your instructions and ended up mining nothing! Can you PM again with hand holding screen shots please. Huge Thanks, I might work in IT, but this is confusing the hell out of me
Does anyone know, if we OC these miners, will Bitmain know if we have a blow out and claim under a warranty repair/replacement?
I presume that there is some logfile that cannot be deleted, and they ask for this to be sent to them for proof over being a naughty boy overclocker?

Reading on tinterweb, it is locked to Balance as these Mini's are, but the Google workaround seems to be working on Big Bruv Z9. I have just placed an order for one. Ships late Sept.
for just over a $100 i invested in another PSU from Bitmain to power the Z9.

is it possible to unplug 2 boards and start with only one board at a time?
that way you could try to find out what each board(PCB) can do?
Don't know if this could help somehow?
Its not advisable to plug powered connectors into yoiur boards , it can give them a spark that could pop something. text book start up is PSU off plug in boards and power up machine then plug in control board.. least i think that way you could try to find out what each board(PCB) can do?
Don't know if this could help somehow?
that's how the Bitmain site says to do it.. i just personally plug all the connectors in then power up the PSU Yes that's correct, i work in IT, and that is pretty much standard way to power any IT equipment. Thinking about it, it is pretty much standard to use ANY electrical equipment, but more so in any IT gear as the circuit boards are hypersensitive to voltage spikes/surges.

Brilliant, thanks imine2. Have not worked out how to give 'Rep' or what ever it is called on here yet, but when i do i will 'Rep' you. Us Newb's can't seem to do much on here
IMHO, i love the B250-FinTech-CF Gigabyte 12 card MoBo. I have 2 of these boards running 24 Rx580 Red Devils, getting 372 M/Hs on one and 375 on t'other. Mining using Hive OS, and both these boards never miss a beat. Easy to add a GPU, easy to maintain, and a pleasure to own.
I have heard far to many horror stories of the 19 rig MoBo's.

Just had another Z9 Mini that arrived today have a chip blow out (x000) when Oc'd to 668 seems that the late batch 2 machines dont just stop hashing when Oc'd too much they loose a chip
Wow man feel sorry for you. Can you get a replacement board?
Just got my batch 2 Mini yesterday. Ran it at 650 Mhz all night and had no HW errors and minimal pool rejects (using nanopool). Getting around 14.8Ksol/s. What's odd is I changed the cgminer.conf to set the speed to something higher but anything higher than 650 just gives me a really low hash rate, around 4.5Ksol/s, even 655 Mhz. No HW errors, just slow hashing. Anyone else experience this?
I noticed the Z9 mini seems to hash slowly unless you select speeds in specific increments. (usually 6 mhz) the only reason I know this is because after I experienced the same thing as you on my manually adjusted batch 2 mini, I looked at the OC options on my batch 1 mini and it looks like they usually let you select in increments of 6 or 7 mhz. I don't really know why but I'm guessing it's a memory timing thing. Try adjusting with the following exact increments until you get stability. 700, 693, 687, 681, 675, 668, 662, 650, etc.Is that starting at 700 and going downwards or starting at 600 and going up? or does not make a difference?
If we crack open the firmware, can we adjust the individual board frequency ??
If you have a Batch one mini that is over clocked, set this to the freq you want the new one set to, save config file, then upload that config file into the batch 2 mini.
tinkering with Firmware is WOW! spookily freakingly scary!
Yes that is on par for a Mini.
I was for a time Hugely Jealous of your 46K shares per day? Maybe it is my pool that is not reporting right
end of the day as long as we are earning who cares about the numbers 
I was for a time Hugely Jealous of your 46K shares per day? Maybe it is my pool that is not reporting right
end of the day as long as we are earning who cares about the numbers Its just a mini, but Maybe its because Im using nano pool, they just added support for the Z9 so maybe theres less people over there. Not sure, but you may want to try them out. I have use them for ETH and XMR for quite a while and been very happy with them.
Even so, a different pool surely would not give you that much of a difference, that's like 7 times the shares i am getting?? Just WOW! How much you earning a day? (USD)
Running at 650 MHz, over the past 23 hours, 46,505 accepted shares, 54 rejected (0.116%) over on Nanopool.
Rejects can have lots of variables, I used to get lots of rejects on my Vegas when I ran XMR-Stak, but after switching to SRBMiner I get almost none. Same thing goes for pools. When I mine ETH on my 1070 rig at nicehash I get lots of rejects, none at Nanopool.

WOW! am i doing something wrong? you get 46K shares in 23 hours? are you on a Big boy Z9 or is my Mini really really underperforming?
Thanks Guys....
Hours run since last reboot (Change Pool) is 21 hrs, Accepted 7685, rejected 30, so i make that around .39%, so guessing that is good/ok!
I am used to GPU mining with lower hashing rates, and i avoid any rejected shares.
Thanks again for Noob help ;-)

Just unpacked another Z9 Mini. Overclocked it to 650.. and board 2 has a chip that blows out (00x0) rebooted it and 2 mins in same again....
Just droped the freq to 500 runs fine.. popped it up to 625 and still fine for now..... board 2 is very lazy 3.61

I am reading other sources that report exactly the same as you, and this is putting me off getting another 2 or 3 of these. I think i will go for the Z9 big boy one next.
May i ask on your other mini's do you get any 'Rejected' shares? As a newb to Asic mining, i am used to GPU mining, and avoid these rejected shares, by dropping the offending card(s) a tad in the overclocking specs.
Not sure in ASIC mining if these are the norm as the hash rate is huge compared to GPU's, or should i throttle down a bit?
Can anyone advise please? or comment?
I have a batch 2 Z9 Mini overclocked to 650, so not pushing to much, getting all three cards hashing and an average 14.5. No HW Errors....
However, i get approx 30 rejected shares in say, a 24 hour period?
Is this good/bad? Is this to be expected if overclocking? Should i reduce overclock?
Thanks Guys
