lol, what kind of voltage are you setting these at to get them stable"ish" and 650MHz? Currently, have two of them at 200MHz in a 7port plugable. I notice they drop hash rate to below 1g periodically, display "missing nonces, Toggling ASIC nRST to reset" Not sure if it's my Satellite connection, the pool, the plugable 7port or the NewPacs themselves causing this drop. Any ideas?

I've run sticks at 600MHz on stock voltage (830) with decent stability. These are set to 860 to help out a bit.

mine are rock solid at 250mhz
using the 10 port bipolar usb hub. which says it can do 10 watts a port.
I think it can do 8 watts and 8 sticks but with only 2 sticks and one on order I most likely won't push it that hard.

Could be a low-voltage issue. Not all chips are created equal. If the average hashrate is still near target (0.228*MHz) it's probably fine but if you still have power overhead it might not hurt to tweak voltage upward slightly.
My six at 650 were missing-nonce resetting quite a bit overnight but the 12-hour average hashrate was still 98.8% of target, which I'm okay with. It was more a stress test for the hub, which was hauling upwards of 95% rated power the whole time.

So try bumping up the voltage a little? Clock wise, quarter of a turn?

¼ is a lot. think of it as a clock and try 1/12 of a turn clockwise. If I recall a full turn is too much which is why I always would try 1/12 of a turn when bumping them up.

Thanks for the advice!
Anyone got a pic of what position it looks like at stock voltage? I'm just interested to know if mine has been fiddled with
Came home today to try to fiddle with voltage only to find the hashing speed very low... like 900M or so. Upon closing cgminer and restarting it shoots back up to target hashing speed again for 30-60 second then the same crash in speed again. It wasn't doing this before either. I've tried increasing voltage as suggested but the same issue. Now I'm wondering if it's my hub, although my Compacs are doing just fine. Any suggestions here before I start chasing shadows
EDIT: Just tried the Newpac directly into a USB port on the system itself... seems totally fine. So looks like I've got a dicky USB hub.

the sipolar on ebay is good https://www.ebay.com/itm/Sipolar-10-Port-USB-2-0-Powered-Hub-with-power-supply-5V-20-Amp-2A-per-port/352409900554?at the moment I am doing 2 newpacs and 1x 2pac set to freq 250mhz with fan cooling them. zero issues http://www.bravo-mining.com/index.php?page=statistics&action=poolContributor Hashrates

I will be getting another newpac and point it to same pool point of interest the 12 volt 10 amp power brick uses 33 watts to do the 3 sticks. about 11 watts a stick at the wall.

I can confirm that the SiPolar 120 Watt 10-Port USB hub Phil posted a link to is a very good hub for these (or any of) GekkoScience's stick miners! You can also get it on Amazon (and it is Amazon Prime eligible) from here: http://a.co/d/firYg2n. There is currently a $5.00 off coupon for the hub on Amazon.. So, it's 10:45AM EST where I live. I just went to order another one of the SiPolar/iCONE 10-Port USB hubs from Amazon and it was eligible for free same day delivery. Should have it in hand by late afternoon - evening time! Can't beat that.

Also this hub intakes 12 volts from a brick. I am pretty sure that a gpu rig could mine these sticks along with gpu coins and you could tap the atx psu for the 12 volts of power. I think this could work for 3 bricks not 5 https://www.amazon.com/60cm-Express-5-5X2-5mm-Plugs-Gridseed/dp/B00MTI68IE/ref=sr_1_10?I think 3 hubs doing 5 sticks each with the adapter above could do an easy freq of 200 with fans. I will do testing of this down the road.

Thanks guys, I'll look into one of them! I'm currently hacking up a hub I've got laying around just to get the sticks up and running in the meantime but they look like a proper solution. Look like nice build quality too!

Pretty much the set up I have, newpac's are coming for us at mfb soon so I'll hope to sneak these home.

Here is my ICONE USB hub running x1 NewPac and x2 2PAC sticks with the latest vh cgminer build, and all at 250Mh/z. Command line/.bat file posted below (with some personal info removed) cgminer.exe -o stratum+tcp://nya.kano.is:3333 -u xxxxx.xxxx -p x -o stratum+tcp://stratum.kano.is:3333 -u xxxxx.xxxx -p x --gekko-newpac-freq 250 --gekko-2pac-freq 250 --gekko-compac-freq 250 --gekko-newpac-boost --suggest-diff 512 --balance And here is a screenshot of cgminer after a few minutes of running. I will post pics tomorrow after I do some more testing/tweaking and add some more sticks.

New build (90e7d31). Some minor updates (medium-to-major if it affects you) Windows binary: cgminer-4.11.1-windows-gekko-90e7d31.7z- Merged in some needed changes for macOS build. - Found and fix a cgminer crash condition when receiving noise from the asic. - Lowered no nonce detection sensitivity. Best practice update process: keep old working version handy. - move the existing "cgminer" folder to "cgminer.yyyymmdd"
- clone repository to create a new cgminer folder as noted from first post instructions.

Thank you vh! For the little time I've been using it, this build seems to be the best yet! I have definitely noticed less instances (in fact, none so far) of invalid nonce resets at higher frequencies.
In an effort to help gain market visibility and ramp up sales, I will be receiving a batch of NewPac sticks tomorrow (November 21) for resale. The first five (5) people to make a purchase will receive FREE shipping on their order (promotion is for USA shipping only). I do offer International shipping as well, and price will vary depending on your location. International customers please send me a message with your address and I will promptly reply with a shipping quote (I will never markup the cost of shipping, regardless of location). For more information, please visit my sales thread here: https://bitcointalk.org/index.php?topic=5071416.0
