Topic: [Guide][Lee Goup] SilverFish 28MH Scrypt Miner– Notlist3d (Picture Heavy) (Read 12491 times)

Actually, I bought my SilverFish from  itopcorp on eBay they said it was tested and worked and had the update (  Latest firmware(06version) Download:http://www.itop-corp.com/asset/file/file/20150313/20150313194758_14233.rar ) and the timer was locked. They also have a website http://www.itop-corp.com/ 

The authorization fix was kinda a eye opening experience.  The worst thing I had with this miner was the longer it ran it seemed to drop in hashrate.  It luckily was something easy to fix with a old school batch file.

I have not kept current on authorization fix.  But anyone else reading this thread make sure you can fix this before buying one or that they have a fix when selling to you.  If not you have a paperweight.  And there may be some great way to get it done now, I just again have not kept current with it and when I owned it there was no issues about it back then.

Oh well, I can put it in a time capsule with a million Dogecoin I guess I will go ahead and build that GPU mining rig which I was going to do in the first place. KEEP ON MINING 24/7 !!!! Peace Out ..

same here i had this thread set to notify.. was like hmmm..   Be something good for him to get his feet wet.. but if its not authorized he is screwed.. and im not sure that there is anyone left to do it.. I can look back and see but the guy that did mine no longer has a qq chat.. so it appears he setup just for this..

Please keep in mind this guide is dated at this point (around 2 years old).   To be able to run it you will need to search about authorization fix.  When I owned one it did not have to do this.

Before purchasing one of these make sure to get current info.  I honestly was suprised to see this bumped up, I did not think many would still be buying this miner

http://cryptomining-blog.com/3059-download-the-sfminer-2-1-english-software-for-silver-fish-scrypt-asic-miners/  check out this site for the software.. norton says its dangerous but thats inherent in crypto files.. They all seem to set off flags..  anyway once you get the software you need to check out this guide for setting it up... its seems well put together.. https://bitcointalksearch.org/topic/guidelee-goup-silverfish-28mh-scrypt-miner-notlist3d-picture-heavy-650608

i could walk you thru this but i find its more rewarding when you figure it out yourself:) plus you really need to know whats going on in case you have issues..  if you get stumped hit me up..

Also i hope that the miner has been reinitialized or else it wont work.. Thats something that was done about a year ago now.. see this post.  https://archive.litecointalk.org/index.php?topic=24884.0

I don't know I was wondering the same thing just bought a SF28 on eBay for $138.50, just wondering if people still use them and if they have any issues that can be fixed or any tweaks to help the run better. Also what kind of power supply is the best and what type of power connectors plugs fit the FS28 just won auction today and need to get a power supply.

Anyway to use raspberry with them?

Have any of you guys lost authorization with this miner.. just in the last couple days 2 /3 of mine have quit completely.. Also has anyone come up with software other than SF miner that will run these beasts!!

How to solo mine with this device?

Bump for the fellow fish out there in the ocean of miner's.  Also check out new hosting price for a professionally hosted dragons at: https://bitcointalksearch.org/topic/wwweasy2minecom-340-the-group-buy-of-antminer-s5psu-included-514758

Also with later firmware and software the restart batch was not needed in my case.  With these fish it does seem to vary depending on cooling environment.

So far the new software is looking promising, have been testing alongside with new firmware and 1 hour reset.

If your's is currently working good and consistent without upgrading I would say stay with your current setup.  But if you are not it's worth using.  Just keep in mind that it's using a Chinese program. Exact same spots as English on buttons so not hard to use if familiar with previous use of program.

Also you can downgrade firmware and use old software if it does not work.

*I have not heard of a single SilverFish having a problem with firmware or hurting it from it, but just putting a standard warning for all firmware.  If power goes out, problem from upgrading, etc during process I take no responsibility on upgrading firmware.

Put a SFMinerR3.04 restart batch file up.  Again you make one from it, for your security I do not make batch files for download.

Still testing will let you know results more on new firmware and software after a little more testing.

SilverFish has released new software and firmware (5th firmware).  Currently testing to see how it does.  Only thing I have noticed is the SilverFish software seems not have a English version yet.

Again will let you know what my results are.

You might try a different pool or look into difficulty.  This is very very high.  Even if hashing at full speed it should not be near that.

That would be correct you will edit both kill and run.  If they release a new version it can be edited as-well.  I hope you find it useful on the batch file.  So far I've heard positive things about it so far.

the price of the SF miner adjust to 1999$ now, also with bulk order discount, you will get at most 150$ discount when place big order
also you can see the following link to see the detail price

I think I found the issue I had in the batch file with the file continuing to add extra occurrences of the miner.  I edited it to change the non-english name to start the miner but didn't edit the kill option.  That should fix that and I'll see how things go from there.

One other note, the reject rate has been running in the 18-20% range even when it is hashing at full speed.

I setup the SF28MH 2 days ago and I've had a great experience with the software (once I found the English download as my Chinese is not good enough apparently).  Sadly though the hardware hasn't lived up to the level of the software.  I haven't been able to keep the hardware running anywhere near the 28MH.  It will run at full speed for a short period of time, usually around 30 mins.  Then it start cutting out on one of the blades and usually will run around 13MH for awhile. 

I setup the reboot batch file to see if that helps but that doesn't really seem to solve the problem.  It will leave the occurrence of the miner open that was running about half speed and then open a 2nd occurrence of the miner that will sometimes pick up some hash rate.  Maybe I missed something in setting that batch file up but if it is going to start a new occurrence of the miner, shouldn't it close the old one?

Hopefully there are just some setting that can be tweaked to get this more stable but so far this doesn't come anywhere near being satisfactory.  It is very power efficient and the software is very user-friendly but it doesn't hash, it doesn't matter.  Compared to ZeusMiner Thunder, the ZM wins hands-down so far as at least it is running consistently at full speed and no down-time.  The ZM is way louder and way less power efficient than the SF but at least it hashes. 

If you have any suggested changes I can make to the settings, please let me know. I am running this with a Corsair 650TX PSU so it should have more than enough power and I don't see anything else that's wrong.
