But at that diff... you little miner will be lucky to find shares... that's why you see things the way they are. I am mining on pools that allow me to set my own diff.

Your Mileage May Very...

I maybe new to this... but your diff is 14k.... OUCH!!!

Anyone else getting all solo mining shares rejected with Zeusminer Blizard?

Have been testing out solo mining on a low difficulty coin for a few hours and have got 5 rejected shares.

Any ideas what the problem might be?

My .bat file is: cgminer.exe --scrypt -o 127.0.0.1:xxxx -u xxxx -p xxxx --chips-count 6 --ltc-clk 300 -S //./COM10 --nocheck-golden

Any help appreciated.

EDIT: Make that 6 rejected shares....

I believe like a gold or platinum PSU would be clean powersource. Using those power supply's that come with the fury I would guess is not clean.

The best I did for clean power is, I changed the outlet to a nice brand new outlet "brown color heavy duty" "American" > Using ISOBAR6 > Tripp Lite OMNIVS1000 > EVGA SuperNOVA 750 G2 > mining farm = 6 gridseeds and one fury.

Can someone please tell me what a very clean DC power source is?

I wouldn't say your unit is bad. It just happens to favor that frequency using the pool you are on. Yes, the pools themselves affect the hash throughput just as much as the difficulty. All my units are stock (no voltage mods) and I am having great results with hashfaster.com, where I am mining as much Dogecoin as possible before the next rewards halving takes place in about 6 days. I also use a very clean DC power source so the hardware does not have to deal with significant voltage ripples.

I am guessing my unit is bad then? or just people with volt mods see the best results?

Not good. Hash rate reduced a little and HW errors went up to 40%+.

I have not looked into the voltage mod yet, but that may be the next challenge.

As far as I know coinking and nicehash are pools which do not work well.
Multipool.us and clevermining are really great... Also others report that single coin pools also working...


Got a Thunder x3 with male connectors grrrr now I have to fix this fabric fail to get it running. Hope my PC dealer has some 6 pin extenders to use instead of cutting the wires of my PSU

I have a question did u try to add 3 units together and have the 120mm fan blow on it ?
i wanted to try this maybe tomorrow but wanted to see why u did the 2 in 1 method

see what 354 would do for you?

First post here so please be kind! 

I had a few hours yesterday morning and gave myself a little 4th of July holiday challenge:
1.Take a few of my Blizzards/Furies from my mini-farm.
2.With ONLY a tray of various screws/wires, thermal paste, and some mini-heatsinks, use the parts that make-up the stock units and reconfigure the design to:
A. Consolidate cooling.
B. Consolidate size.
C. (Hopefully) improve performance.
3.Enjoy a nice cold Hefeweizen and whistle while I work!

(Items also present on my work bench = Weller soldering iron + solder, razor blade, Phillips head, and hex head drivers)

After repasting and improving the PCB to aluminum casing thermal transfer, the mini-heatsinks were applied to each individual ASIC. Next, I combined the V+ input of each set of (2) miner boards before running a new power feed line to the rear of each pair. I then soldered one of the available fans to one of the available PCB's. Everything is now reinstalled in to each cashing set and joined with the original fan housing bolts, which are also used to [temporarily] secure the now vertically mounted blower-fans. Just for extra cooling assurance, one of the other extra fans is plugged in to the stock location on the PCB and retained on the top of my "mini-tower of 5.5MH/s power" by seating it so its mount holes securely rest on the union bolt/nut tips. Lastly, to keep each pair of miners level, two M3x40mm hex-head bolts w/ nylon lock nuts are used in place of the (2) rear PCB mount screws on the lower miner of each pair. Now each pair of miners can be stacked and hooked up!

My opinion of the results: Veni, vidi, vici!

Overall, the units are running cooler and I can see approximately a 10-15% improvement in hashing effectiveness - including less HW errors (only approx. 10 over a range of 1000 accepted shares with less than 5 rejected shares). I am going to continue to test and see how it does over the weekend.

Update: Now I have 8 units made into 2 towers. Numbers @ 340MHz are looking good (see below). 

Scott-

Nice work.  What software are you using to control them?   

It's beyond me why they didn't put all the connectors on one end in the first place...stupid design to plug crap into both ends if you ask me.
I just converted all my equipment over to 220v/240v circuits.  I have some more hardware arriving this week and really had nothing better to do besides mow the grass.  Figured I may as well get as much efficiency out of the power being used as I could.

Amp readings before and after? Awesome you did this... At least amp readings? Amps should be very much lower. More efficient and less electricity. In theory.

Edit, picture of the job?
