Yes, I think some guys with bigger miners wanted that. Under volt it a bit.
I'll run --chips-count 8 for a test (if it continues to look stable) to see if a slightly faster Readcount Timeout helps or hurts. It'll will be a 24hr test.
Note: if you set more chips than what you have your hashrate in the miner software will be wrong. It will report 70% of --ltc-clk multiplied by the number of chips you choose. If you set less chips the hash rate will appear low. If you set more chips the hash rate will appear high. The miner hash rate is not accurate. Poolside hash rate is what matters.

A volt mod would be great. Not too much, we don't want 100 watt glowing bricks  A nice stable 1.5mh/s or 1.6mh/s would be awesome. another interesting quote from Terry from Zeus on Litecointalk forum: https://litecointalk.org/index.php?topic=16301.msg180519#msg180519we were okay (in a/c room) about 340~350ish at stable speed. but anything above that you would have a lot of errors 350 x .7 = 245 kh/s x 6 = 1.47mh/s that could be our first goal, maybe obtained by keeping it nice and cool but beware: ..... but please make sure you are doing it in cool ambient environment because over heating WILL damage the hardware. caution is advised |

Earlier we started talking about voltage so here's a copy: here's the post re: Zeus voltage https://litecointalk.org/index.php?topic=16301.msg177074#msg177074it's possible for a physical mod. if change some of the resistors to get it to work at 1.2 ish V, you save some more power there comparing to 1.3.
power consumption is related to voltage it's running on, which is tunable with hardware mods. nst6563's photo shows 1.2v printed, I wonder if the voltage is already upped a bit? and nst6563 had this info: I measured the 1.2vc mark and it reads 1.26v. So if the chips were originally spec'd at 1.3v, there's some room to play with. As for IC's....I don't have a camera other than the one on my htc....but around the choke are all the same type of mosfet with the markings: 2R030 PEM 1349A6 4214 The other chip that looks to control the voltage is marked with: 0193 391 CCON Since this is a Fury, there are NO markings on any of the ASIC IC's themselves. The only other IC with markings is the Silab's USB interface - which from my understanding can support up to 1Mbps transfer rate however the Fury/Blizzard have it limited to 115200Kbps (could there be some performance gained by upping this limit?? It appears that the chips themselves are daisy chained to a nonce solved by the last chip in the chain has to travel through each chip before it and then to the interface....it could be possible that more data is flowing through the port than 115200Kbps can effectively handle I suppose). :EDIT: So it looks like the 0193 chip is possibly this TPS40193: http://www.ti.com/lit/ds/slus719e/slus719e.pdf |

Thanks for starting this topic. I think the Zeus Blizzard and the Gawminer Fury are the same. This is a good link to Zeusminer info: http://zeusminer.com/user-manual-ver-1-0/ There's the Zeus chip doc there for download. From the doc we know the chips have 8 cores. Also it indicates the hash rate is approx 70% of the clock rate if "--nocheck-golden" is used. So 340 clk would equal 238kh/s per chip x 6 chips for the Fury = 1.4mh/s approx 328 clk would equal 230kh/s per chip x 6 chips for the Fury = 1.377mh/s approx You can manipulate the Readcount Timeout by changing the "--chips-count" cmd parameter. Doing so will distort the hash rate displayed by cgminer. I played around with that but haven't come to a any conclusion if helps yet. Setting 12 chips reduces the Readcount Timeout by more than half I think (on a 6 chip device). I set 400 chips for a test. It slowed the miner down a lot but it was fun seeing a spoofed 90mh/s hash rate in cgminer. Readcount Timeout is explained as: 4.3 Readcount Timeout
After we send one command packet to the chained chips, that BIG chip will cover all the 32 bits nonce in a certain TIME. So we must send a new work to it before that, otherwise its hash power is wasted.
Cgminer’s readcount timeout is used for that. Every count means 0.1 second. We now set the readcount to be 3/8 of the covering time. It may be 3/4 later.
I'm currently running 340 clk and poolside it was 1,374 kh/s after 24 hours. |

The Fury needs a voltmod! 5% hardware errors is "normal" right now.
Had you asked me this morning I would have said forget it. I'm not used to so many rejects and hardware errors. The gridseeds run way more stable.
But, this afternoon someone on Litecointalk released a first attempt of BFGMiner and it's a big improvement. Still 5% HW errors but hardly any rejects.
There should be some overclock room. The 328 clock that most seem to run results in about 230kh/s per chip. That's already a bit of an overclock from 210khs (300 clk) which would be what Zeus last spec'd the chips at. These chips started off being promoted as 300kh/s chips way back. The problem is power consumption of 8 watts per chip now at around 230kh/s.
I'm running the Fury at 340 clk which should be around 238 kh/s x 6 chips = maybe 1.4Mh/s with 5.7% HW errors. 48.75 watts for just the device itself. I'm waiting for 24hr poolside results then I'll adjust up or down.
Remember how the voltmods really seemed to stabilize the Gridseeds? That's what I think the Fury needs right now - get it stabilized. But, because it already using 50 watts there might not be much to gain. Who knows? Maybe half a volt more would stabilize these things.
I'm not 100% sure but I think Terry from Zeus mentioned 1.3 volts as the voltage in a post on Litecointalk. Fury's & Blizzards might have potential for a volt mod. Zeus needs to leak a schematic so the pros here can figure it out. The 12v 5A power supplies that come with them are already maxed out though. I used the same type of plug as I used with my gridseeds.

MoonShad0w384 - have you tried Sandors cpuminer-gc3355 ? https://github.com/siklon/cpuminer-gc3355Note: You'll want your fan running before you do  I have two unmodified pods doing 396.1 kh/s & 397.1 kh/s on cpuminer-gc3355. I just haven't gotten around to volt modding these yet. My other pods are vmod3 I curious to see what Sandors cpuminer-gc3355 + vmod1 would do. Anyone here have that combo? At some point we might all have to revert to vmod1 to save a few watts. One profitability calculator I used today said my Fury wouldn't cover the cost of electricity to run it by next Feb! |

With recent news, I'm glad I went with GAW.
I did have some downtime issues, but even my home hosted stuff I've had issues as it's a chip quality issue I guess.
Josh compensated me for the downtime and has always responded same day.
Scrypt ASICs are crazy home hosted, I only do it in a shed lol, but having them hosted elsewhere and compensation for all issues, is relaxing actually.
This is how GAW works, you just need to contact them directly if you're having any problems, and they'll take care of you. Sometimes they need a public push in the right direction. Going private on the used miners didn't help me at all. Ended up needing the community here to give them a nudge to do the right thing. They did give me some store credit though which was appreciated. I hope they clearly list used miners as used going forward. I'd expect them to have some if upgrading customers older stuff to newer miners. I hope GAW rejoins BTCTalk. |

I just got the unexpected Zen Controller / Raspberry Pi gift from GAWminers. Thank you so much! I've never received a outright gift like that from a company before.
And I got tracking for my Week 1 Fury - maybe slightly behind schedule but the free upgrade to DHL courier more than makes up for that. It will get here days sooner than regular post.
Thanks for everything GawMiners!

Here is another contest to pass the time while you wait for your miners  As you guys know, we have some fun name that we use for things. Believe it or not, I make them all up, but for very specific reasons...... I will give a free Fury (second week). To the person the person that guesses the closest to why we choose all the names for everything related to our company first Cut off is 11pm Eastern Tonight! They're all part of a team with integrity and high ideals. |

You should create a new miner and call it gawrilla
I want a GAWrilla ! GAWgasmic, The Fury should be retitled the "GAWnado"
and a GAWnado ! |

Check out the GAW-tacular deals at GAWminers. I got a GAW-tabulous miner from GAW. UPS guy showed up this morning. False alarm, he must have thought I was nuts doing back-flips on the lawn for getting two printer ink cartridges! I explained that I had GAW-itus and I think he understood.  |

I'd like to see GAW begin accepting LTC and maybe expand the store to more than selling hosting and miners. Maybe sell retailer gift cards (Amazon) or stuff like that. I already pay a few fees exchanging LTC and withdrawing BTC so a small price premium for the convenience of one stop shopping would be fine. They'd have to see if there is a market for that. I've been spending the mined coins so not sure if most people use the coins or keep their mined coins. Then maybe GAW-Xchange, GAWTrade, GAWPool, GAWBank ..............  Seriously though, you've established a lot of trust with your customers quickly so you should be able to expand on that. There may come a time when I don't want more miners but I could see buying other things from you because you understand that customers like competitive prices, fast shipping, easy check-out and status updates etc. |

If it is zero value, like what is shown in on the .brd file, what is the function / purpose of a zero ohm value resistor? Just curious. Is it like a short?

I have to stop trying to figure this out  Gotta have more patience. I'll probably have the miner up and running by this time next week. |

Here are the official power numbers: Fury- 25-35w Black Widow- 320-380w Falcon- 640-760w War Machine- 1280-1520w The range depends on the difficulty of the pool and a few other factors. Note: these numbers are before the over clocking. Hope this clears things up. Please send questions and request directly to: info@gawminers.com
Thanks! Those power consumption number are way different than Zeusminer batch 1 (now closed) numbers after last Wednesday's update by Terry from Zeus and his subsequent posts on Litecoin.org Blizzard 40W Cyclone 800W Thunder 1600W Lightning 3200W Lightning Package consists of 4 * 4 blade miners (each 800 W) with a total of 88+ Mh/s
Thunder Package consists of 2 * 4 blade miners (each 800 W) with a total of 44+ Mh/s
Cyclone Package consists of 1 * 4 blade miner (800 W) with a total of 22+ Mh/s GAW must have completely different number of chips than Zeus or maybe not even using Zeus chips. We'll know soon enough. I can't wait to get the unit I ordered ! |
