profitability for the usual algos is going down, anyone knows some new one (or old one to revive) worth working on?

NEOSCRYPT--

There are couple coins with NeoScrypt algo that have low difficulty and good volume (diff<1, vol~2.5 BTC).  UFOCoin is one of them.  I still cannot solo-mine FeatherCoin with sp_'s CCminer, and receive communications errors with the wallet.  It may be the error that T-Nelson pointed out, where a 168 bit data block is transmitted as a 128 bit data block?

SecureCoin blocks keep coming in with the Quark algo.  I might download the UFOCoin wallet and try it, but I think that there is still some code to tidy up.       --scryptr

Looking at the code for Feathercoin and Phoenixcoin, they seem derivative and to send an 84byte blockheader since switching from scrypt to neoscrypt on a fifth and fourth hardfork, respectively.  However, from what I can gather, neoscrypt wants an 80byte header, as ccminer handles.  I'm not sure if they're sending "padding" for the nonce or it's a bug on their end, there are no comments in the code for assistance.  Does this work in djm34 or tpruvpot forks?

UFOCoin uses scrypt, so should have a 128byte header and work.  From a brief glance anyway.  It could be some other bug.

Some of the dev here: https://forum.feathercoin.com/ could probably help with that I'm sure.
I looked for the old to new fork "core" thread but it seems they have renewed the forum since
I was last there and a lot of the old threads "about a year old" are no longer there to be found.
Sorry no time to test yet this morning, will when I can.

Hi,

I'm a newbie to mining with nVidia GPUs and would like some help getting mine working.. I've had some experience with sgminer but couldn't get ccminer to work.. I'm mainly trying to mine VertCoin (Lyra2REv2) on NiceHash but I never get any accepted shares and my GPU load is very low.. I'm on Windows 10 right now with the latest driver and with the latest copy of the executable. Any help would be really appreciated.

-- theLosers106

Would help to know the hardware used. This ccminer only works with maxwell cards.
Cards below Maxwell will only idle after load of the software.

Code:

The NVIDIA GeForce 820M (or GT 820M) is an entry-level DirectX 12 compatible graphics card announced in January 2014. 
Its core is based on the 28nm GF117 chip (Fermi architecture) and is equipped with 64-bit DDR3 memory. 

I see.. That's the problem.. so my new 960 should work with this ccminer right? If I still want to run ccminer on my 820m, which fork of the ccminer should I use or is it not possible?

It looks like the 820M is compute version 2.1.  I don't believe any ccminer fork uses 2.1.
The 960 is compute version 5.2 so will work with multiple ccminer forks.

NO WALLET FOR UFO--

It looked decent on CoinWarz, but research turned up no Windows binary for the wallet.  CoinWarz has UFO as a NeoScrypt coin, it was scrypt coin as was FeatherCoin. A lot of outdated info is around, but the wallets in existence were not synching a couple days/weeks back.  I think if I actually had a wallet, I might be a UFOCoin millionaire, but unless I get a response for a wallet, there is no way to mine solo.

KBomba has a ccminer v1.02 that will mine on compute 2.1.  Look on "github.com/kbomba" under releases for "CCminer-Kbomba", released May 19, 2014.       --scryptr

Anyone know if there is a way to still see the output in the miner and also put the info into a log.txt.
Command line please if there is? I know how to get it to log to a file, but would like to also see that info in the miner still as well while log to .txt.

On Linux you can use the "tee" command.

Not in Linux, thanks. W7
I was thinking the intensity might be broken in the new release, but seems to be working. This is from the .txt it creates
Haven't checked it without logging to file to see if there is a difference posted there in the miner window..
actually this is 22.9:> 22, 7969024 cuda threads
This is 22:> 22, 4194304 cuda threads no .x number was used.

so far there are three more that i need to setup ...

- tsiv ( still no contact ) ...
- pfool - have all the details now ...

I've never understood this. Why don't you input their BTC address on a multipool or Nicehash and mine to it? Or if you're really picky and want to differentiate yourself from normal donations, ask them for a new BTC address just for mining.

HAMPSTERWHEEL MINING--

It started as a joke, in this thread, about the time Neoscrypt was really a hot algo.  I kept saying I would mine on my "hamster wheel", a 6x 750ti rig, for the code.  I did, for a while.  Why be so critical?  It is another way to donate, and privately.       --scryptr

KOPIEMTU --

I took a look at jk_14's instructions at the end of the kopiemtu thread.  He wants to merge-mine VTC and his MBL coin, both on the Lyra2v2 algo.  It is a bold challenge, but I need to work on my hardware instead of get wrapped around that axle.

I have a wallet full of parallax coin, and another full of monocle coin.  I hope that jk_14 comes out on top, good luck!

I am still looking for a UFO wallet, and have some SRC on the market...

P.S.  I need to mow the lawn, and buy groceries, and return a rented DVD, and fix the plumbing, and...  jk_14 must really know Linux.       --scryptr

THANK YOU!--

You may very well be right about the wallet.  I can get DJM34's CCminer launched, and communicate initially with the wallet, but I never get any card hash reports, only an initial blue neoscrypt block number report to the console.  With sp_'s CCminer, I cannot even get that far, just a red error message.

GTX 960 SSC on Win 7 x64 solo-mining VTC

I just launched my GTX 960 against my VertCoin (VTC) wallet.  I am getting card-hash reports, but no VTC block number reports (blue), at least not yet.  I need to do stuff, I'll check back in a while.  The card is hashing, like before the fix.  6.1Mh/s, it will take a while for a block.       --scryptr

Possible fix for neoscrypt solo mining by tpruvot:

Yeah we worked it out on IRC.  I'm 100% sure this needs fixed in the wallets, not the miner.  I'm willing to add it based on a non-default flag for the time being though.

THANK YOU!--

You may very well be right about the wallet.  I can get DJM34's CCminer launched, and communicate initially with the wallet, but I never get any card hash reports, only an initial blue neoscrypt block number report to the console.  With sp_'s CCminer, I cannot even get that far, just a red error message.

who here can confirm any working miner for lyra2v2 algo coin solo-mining?

IIRC the blue text is only for stratum info.  You're soloing, so no stratum.  You'll only see GPU report at the end of a round and accept/reject.  Just let it run

Anyone want to give solo-mining MobileCash a shot? (lyra2v2 algo, rpcport=14414)

https://bitcointalk.org/index.php?topic=1182734.0

I've been at it all day and cant get any coins into the wallet with either SP_'s or DJM's miner.  I get an accept message in the miner but then it does the "boooooo!" or "nooooooo!"

there are a couple of lyra2rev2 coins which have forked an older version of vtc wallet then upgraded the algo, and they have a bug in the getwork protocol.
The only possibility to fix it, is by fixing the wallet (which was done for vtc), in the current situation there is no way to solo mine these coins

T Nelson fixed the solomining bug. Please donate some beers to him if you solomine....

CONFIRMED FIX!--


SP_ release dot 69 finds block solo-mining SecureCoin (SRC).

First block found on my rig with release dot 69!       --scryptr

EDIT:  LUCKY BLOCK!

Did you try the http protocol from another computer to the same wallet all on the same hub?
