If you are in the US,  is it possible to pay the driver on delivery with cash or personal check?   I've made a UPS account and entered payment details, but I see no way to assign the shipping invoice to my account for online payment.

Delivery drivers in the US won't take cash.  And I am sure they won't take personal checks either.  I have been shipping since the 1980s.  C.O.D. used to be a popular option but went away a long time ago.  Driver's didn't want the responsibility and the risks.

You should find your local UPS office and try to pay there.  Might be able to pay at a UPS store.    

UPS drivers take checks. They can't take credit cards in person, but they can if you call the dispatch office.

EDIT: for customs fees. Not sure about COD, but I assume they can as well if they knock on your door (if they take it on the truck for delivery they have to be able to accept payment somehow).

UPS operator told me check or cashier check only if receiving at location...or call before arrival and you can pay however you like(credit card, debit, electronic transfer etc etc)

Thanks, just upped mine to 750mhz as well, seems to be stable!

Im using a 1400W Dell server PSU, which outputs 12.9V, pulling 393W at the wall @ 750mhz.

For those of you who overclock, especially going right to 750 - do you have to set the fan to 100% RPM? Or does it automatically ramp up with temperature? From the few videos I've seen so far, the stock settings seem not to be so loud... but the full-rpm noise (heard during bootup?) sounds a bit much.

If you're going to put a Z9 Mini in a room in your house, maybe you'll have to dial in an acceptable fan RPM first... then slowly up the overclocks until the chip temps hold 65 degrees?

So considering I purchased one @ $850 for shipment in late August, are the chances of me making any profit from mining with this slim? Also does Bitmain ever ship batches early?

I would use a $420 or less coupon to lower initial cost. If you don't have a coupon you can buy here on selling forum or on eBay.

That’s actually what I did - found a $420 coupon someone was selling for $150. Ended up paying $782.73 total for the miner, APW3 PSU, and DHL shipping to the US. I almost ended up getting 2x of them with two coupons but the wait time turned me off from doing so, since I didn’t know what would happen between then and late August.

I guess worst case scenario, I’m pretty sure I can resell the miner to someone in the US and make my money back. Seems like there’s always people wanting ASICs, even if they’re not even profitable after paying for power. Never understood that. Btw has anyone purchased a single miner and shipped with DHL to the US? If so, how much did you pay in duties/fees? I heard from someone else that miners are exempt from duties in the US, but that seems false since i highly doubt that shipping companies even know what miners are. I actually purchased a Trezor from Switzerland and it was shipped out via DHL, didn’t have to pay any duties or anything like that. Could this also be the case with the miner I purchased?

Needed fan speed depends on environment temperature. As an example, mine are located where environment temp are ~20c with a static fan speed of 85% now Z9`s chip temperature is about 63c. At that noise level i would not have it in house.

By default its set to automatically adjust fan. I just dont trust that one when i OC.

Get used to it, at least as long as we have this administration. This is what a trade war looks like.

77 + 607 + 748 + 2002 + 2337 + 549 + 2422 = 8742 so far, with the last payment date of '2018-06-20 20:44:39'. Lots of 50-unit orders in those last two batches too: $100000 orders?!?

And still going... maybe batch-1 was 10000 units?

Hey Vos,

Thanks for a great video.  Watched it a couple of times now.

Do you know if we can mine on MiningPoolHub, and let AwesomeMiner switch between the most profitable coins for the Equihash algo? 

I read like the last 10 pages on this thread, but did not see anybody that got it right.

Thanks,

KoiMundi

The benefits above 630 are trivial tbh.

I have 1x z9m on a cheapo 500W PSU

and I have a IBM 1400W with 3x OC z9m and I'm pulling 975W.

minmax to naxx baby.

Check the Pool Thread but here is my last update on that topic.

I'll test mine on Prohashing when I get it but I'm waiting on tracking

Someone posted over on Prohashing, looks like the Z9 is not working there at this time.

Just saw an updated post on Prohashing, it is reported to be working using the algo specific equihash port 3336. I will have my Z9 soon and will confirm.

I suspect this should work on 3336 because my GPU miners work better on the dedicated port.

Ya...at best only zcash will be remaining on equihash by the time you get your unit with very high difficulties you'll be looking at a 1-2 year ROI unless you did a coupon deal...no point in getting anything but batch 1.  

No one knows what the market will do. Profits could shoot up in a month's time... or not.

So, what would you guys say the chances are of batch 2 (Aug 24 ship date) being worthwhile? 50/50? I'm willing to take the risk as long as there's a reasonable chance of at least breaking even. Just because I think this mining stuff is cool. Cool

LOL @VoskCoin... making a deal with the devil.

I think it's machine to machine. Mine seems to peak around 700, others see improvement at the max 750.

DHL is apparently hit and miss. I've used them for a couple orders and paid zero import fees, and both deliveries were on time. However, I HAVE heard reports of import fee problems and miners getting stuck in customs using DHL, so YMMV.
