Topic: Fury/Blizzard tuning and mods - page 25. (Read 115254 times)

I do agree on the fact that the devices are a little disappointing:
Power draw is higher than expected
hard limit on overclock that isn't easily removable even if there is still plenty of room for extra hashes on the board.
Extremely fast price drop in the first weeks.

But the good thing is that Gridseed isn't alone anymore and prices are going down.

For those not happy with Zeus, the G-Blades are a good alternative, and the upcoming G-Black, even if it's simply 5 G-Blades in a box, still have a fair price compared to Zeus. It can also overclock "easily" to 35MH/s, probably 37-40MH since they revised the PCB.

Return on investment in crypto is always the same story.
It will depend on which coin you mine, when you mine it, and its value in a few monthes if you hold it.

If you hold the LTC you are making at the moment, and LTC goes up to the point it was in december 2013, you will make profit.
Of course, sometimes, you can make more profit simply buying the coins and waiting, but it's really less fun.

And I like to mod/improve things, so all the new miners that should be available in Q3 will have some room reserved in my collection if I can afford to buy one.

Next one on its way home for tomorrow is a Rockminer, and after it, probably a hurricaneX3 (cooling can be greatly improved on this one and I'd like to see it at 18MH/s)
A2 miners are still too expensive for me to play with them.

Really not sure why he is so angry...

Like I said... My 3 are working great.

Setup...

1x RPI running the latest CPUMINER (set to autotune)
16x Gridseed Mini's
1X RPI running CGMINER 4.3.5
3x week3 Fury's (clock @328, diff @ 512)

Total poolside speed = 9.7 MH\z with 0.8% reported rejects (Clevermining)

I am not a 'paid shill'. Just a very happy miner...   

Wow chill guys, take it easy..

How do you host a pic on here and I will be happy to show you...

Ahh, i see. I get ur advice.

Actually i do have the plan to go into industrial operation hahahahaa. Thats what i wanted to do when i started.

Don't forget 4-5% is the diff today -- However, in Q3/Q4 tons of new hardware coming from KNC, Fibonacci, Alpha, MAT, etc.  So that diff will jump up even more...I'd say we'll see 4-5% through mid-July...and after that we'll start to see some real increases.

Honestly, if I could use 20/20 hindsight to go back to Feb when scrypt-asics first came out with Gridseed hardware -- I would never have bought any ASIC hardware.  Just not worth it.  I would have bought coins instead and just sat on them.  Not as fun for sure but way better investment (in my opinion).  Don't get me wrong, I love mining, tinkering with my miners, learning a bit of linux on my RasPi...but the arms race is only going to get worse...we saw this pattern in BTC and its going to happen again in scrypt: from hobby mining --> small-timer farms --> asic mining --> industrial operations only.

So if you do buy mining equipment, you need to be "ok" with not breaking even or making any profit at all.  If you can't accept that as a very real possibility then just buy the coins and sit on them.

I did a run through. Breakeven around 5 months

Personally I wouldn't spend another dime of my hard earned money to support Zeus after their treatment of Batch 1 customers.

However, lets put my history/bias against them aside for a moment....

If you have the money, and you're interested in mining then it seems reasonable.  Did you run this through any kind of calculator to see if/when it could break even?

I think the challenges with that many Blizzards will be the fan noise, cable mess, and if a RasPi can handle that many on a USB hub.

Alright peeposss i am back.

Well i did some calculation and i realize, buying 17 sets of Fury = 1 set of Falcon

And it consume less power, cost cheaper.

Cheaper by $500++ and u save 350++W on power.

Do you guys think this is a good plan ? Was planning to do this.. seeking opinion

I'm using CGMINER 4.3.5 with 3 stock Fury's on Clevermining and am averaging 1.42 MH\s each miner. With only 1.2% 'R' and about 5% 'HW'. This is running at 328MHz with a diff of 512. The Fury's have been running solid for 48hrs now.

I have been very happy with my Fury's!!!

Hi Everyone,

My CSR staff is getting back to your request as quickly as they can.

But, if your having an issue that your not getting the help you need, please email me at [email protected] and I will be happy to personally help you. Thanks

These are harder to get running the way you like right away than Gridseeds for example. (my opinion)
But, once you find the right combo of pool & software they run well.

I don't set diff on either pool.  The pool adjusts automatically based on my miners.

Get a copy of beta 1 too.  You might find it works best on some pools.

350 might be too high.  Try 340 or try a different build.
Your rejects are high:
A: 593920 R: 26624

Mine look this after approx 12 hrs.
A:1067162 R:7752 WU:1507.6  Beta 1
A:1134848 R:1536 WU:1489.2  Beta 2

That's two different pools.  Beta 1 or 2 will work on one pool.  The other pool get a lot of rejects with beta 2 so I use beta 1.
Are you getting what people are calling a wall of rejects once in a while?  That's what I got on one pool with beta 2.  But beta 1 works on that pool.

Beta 3 was released last night: - Dmaxl's CGminer-4.3.5 Beta 3

Somewhere ind the Litecoin-Zeus thread Terry stated that WU has to be multiplied by 1.09 to get the pool side speed. But nevertheless it is really under performing. I also have such a dives...same config but is constantly performing 150kH behind the others

really nice. so it is good to see that cgminer is now on the same hash level. This solves much pain points in my bfgminer build.

As cgminer sometimes causes issues on my PI (freezes and lags) I am currently stay at bfg and look if I could do something to the community if same issues are recognized.

Hate sometimes my lack of programming such drivers

8 gridseeds + 2 Fury's on Nicehash.  You can see the large dip in the graph where the 2 fury's were offline (I was using bfgminer but took things offline to flash the new release of starminer and clone/compile the latest dmaxl cgminer), take note of the Minera hashrate (last tab in Firefox) sitting at 3.5Mhs.  I'd say the 2 Fury's are more than pulling their weight...and from the looks of it dmaxl's cgminer work is catching up to the speed of bfgminer.


and btw....I had been using your builds of bfgminer up until this latest release of Starminer (6/27) for mining on Nicehash (you can see the first peaks in the graph - that's bfgminer 4.2.2).  It seems to have some problems with the other pool I use so I have always had cgminer on the sidelines for mining at my other pool. 

Which RPi GUI image do you recommend the most?
I love BFGMiner but I want a Pi image I do not have to compile and mess around with that I can still overclock and such.  I need this to give a miner to a friend who is not technically inclined at all.
Any suggestion out of everything here?
I would just give him a ZenOS controller but I want it to be independent so he can learn as opposed to just clicking.
Thanks again for the great work.  I use your BFG release with MultiMiner.  So sweet.

more interesting would be what you get on pool side. The miner/GUI can talk much but the accepted hares are counting

I like your numbers!

I downloaded and burned the Starminer image yesterday.  I haven't mined with it yet - just booted up the Pi.  I think I'll end up using it.

Dmaxl's beta 2 is pushing the 24hr avg up for me.



I think it was 1,586 kh/s when I started using it 4+ hrs ago and now it is 1,601 kh/s.  WU is at 1,542/m after running 4+ hrs.
I was going to switch pools but I think I'll let this run 24 hrs just to see what it peaks at.
