Hey Darkwinde - I've been testing out your latest bfgminer on my rpi with 2 Fury's.  I'm getting VERY inconsistent results.  Although the hashrate shows higher, I get a VERY high number of reject compared to Dmaxl's builds of cgminer on Nicehash, and otherwise a wildly fluctuating hashrate (same speeds between cgminer and bfgminer).  Is there some setting I'm missing?  Must be because I see so many others that are getting good results with it....

cgminer is highlighted in black, bfgminer in red.  The tests were performed against the Nicehash pool, I just switched to coinking for a bit when I took the screenshot and noticed nowhere near the level of rejects as on Nicehash...but I still see a very erratic hashrate which fluctuates down to near 0 at times and upwards of 7.


crap...forgive the typo in your name on the pic...


..."darkwine" is a nice nick...LOL... Grin

Just kidding...


BTW, did you really got 1.71MH on your Fury(s)... Huh


Cheers,

ZiG

Well, the clock was set to 381 and that's what bfgminer was reporting...but poolside was VERY inconsistent.  I couldn't tell what hashrate it was getting.

Poolside:


Starminer report:

In the starminer graph, the usage of bfgminer on coinking starts at the Thur 18:00 mark.
Poolside was all over the place.  I'm going to go back to dmaxl's cgminer and do a run with it on the same pool for the same amount of time to see if the poolside graph looks different.

I just learned something looking at your screen shot.  I didn't realize the coinking graph keeps tracking hashrate as long as you're logged on.  I've been logging on and checking then exiting.  the graph was only a couple of minutes.

It'll smooth out with cgminer.  I'm still running the first release.

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


Got replay from shipping team  Roll Eyes  they will send out 4 replacement wires Cheesy WUHUUU but do not think that this will arrive prior Thursday Sad
So I still have to do a bit customizing to the connectors to get started today ^^

correct but a manufacturer cannot expect that everybody has a modular PSU with explicit 4 female PCI-E connectors as IN.
My PSU has this not as it combines two PCI-E 8 PINs to a 16 PIN IN with a Pin placement like:
0 0 0 0 12 12 12 12
0 0 0 0 12 12 12 12

so no chance without cutting the rope to get it fit Smiley

So the best would be that Zeus uses wire with female connectors in stock and places 4 additional male connectors to the package that all setups can be covered Smiley but this would be the German approach I think Cheesy

Here is the distribution matrix of my PSU...

Got only one female adapter Sad
Nevertheless one blade is now running with 7.2 MH/s, 2.6% Reject, 4.8% HW Error  at 340MHz
As the rest of the connectirs will not be delivered prior Monday I will use the time to clean up the other blades and give some MX-2 to them Wink

There are people on Hashtrader speculating that it's gameover period for GEN A miner. What do you guys think ?

Well a Fury would net like 64 cents a day mining straight LTC right now according to CoinWars. 71 cents mining Doge. It goes lower every couple of days.  So it won't surprise me at all if people stop buying equipment at current prices.


I was surprised to see the current weeks price for the Fury is the same as last week.
Wouldnt surprise me to see it for sale around $69.95 within the next 30 days

The power circuit can handle way more than what the overvolt needs.
Zeus even removed one of the power MOSFETs from the lower gate to save a few cents on the build price in the newer ones I received.

You should be safe with proper cooling of the 6 mining chips.

I just have to say i been reading this thread and thanks to alot of the info here

1.) i set the clock to 338 ( seems to get me the best results )
2.) i wiped off all the thermal paste that was on the board ( what was that crap )  - I added better MX paste to one of the units / the other i used atric sliver 5 paste
3.) running now 20 mins and 0 HW errors before it was at least 2 HW errors in that time frame.
4.) i did not do the overclock yet - I might do it who knows ( is it really worth it ? )
5.) getting 1.3MH to 1.4MH per board right now

has anyone mounted two units together ?
i plan on running to home depot and getting a few bolts that will help me do this. thinking of placing 2 together and maybe 1 on top of the 2 for a total of 3 units running together

seems both paste work alot better then the paste that was put on in the factory i would tell everyone with these units to do the paste over asap.

tl:dr the entire thread.

Are people having better results with Furys or Blizzards?

Or, are Furys owners having great results with their Furys and Blizzard owners having great results with their Bizzards?  Cheesy

Look for my mini-blade mod.
Except for the 2 side panels and a 60mm fan, you don't need any material.
1mm thick side panels allow you to use bolts an screws from the existing fan to attach both blizzard together.
And I use the same bolts and screws to attach the 60mm fan.
60x35mm fan is very noisy but gives me the best cooling. They are cheap if you look for second hand HP server parts.
Fractal design 60mm 20cfm 17db is nice and silent, but 20cfm is just enough after voltmod. Don't go lower.

I'm currently working on a mini-blade X3 design that should be ready by Monday.
Triple overclocked Blizzard for 4.8-5.1MH/s

thanks for the info i just made my 2 units in to 1 Smiley
simple i just took out the 8 screws for the fans and then used 4 screws 2 on each side to go threw the board to the other heatsink and then used the bolt to connect.
I will post a pic in a few mins.

I connect these to a psu in a computer

I get WU : 26XX to 27XX with these connected just like this.
now i just need another one of these to add to my 3rd one i have so i can built it just like this one Smiley
how much extra hash do you get from overclocking ?

First post here so please be kind!  Grin

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).  Cool

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?
