Hi people,
im new here and can someone tell me why no shares and what i make wrong, i use:

-o stratum+tcp://middlecoin.com:3333 -u my wallet address -p 123
and nothing http://s861.photobucket.com/user/scotty_tu/media/middle_zpsabb88813.jpg.html

Did you miss --scrypt by any chance? Looks like it.

yes i didnt use it, because when add it, just start and disapear.

I don't think you are hashing 335 Mh/s with scrypt.  Make sure you have scrypt configured and not SHA-256

If you don't add it you cannot mine. You have another issue and it is not the fault of adding -scrypt

@Humbleminer: thanks, that's exactly what it was!! Now finally mining away with all 6 gpus for the first time!! Epic!

2 things though:
- vddc shows 1.2v in the web stats interface but max 1.14 in my conf file... And ccc seems to confirm max at 1.14.
- hashrate is 15kh lower per card than in Win8.1

I see AMU... that means you're trying to use an AsicMiner Block Erupter.  You can't mine on Middlecoin with that.  It's a SHA256 only ASIC.  You can only mine direct Bitcoin or other SHA-256 based coin pools.  Middlecoin is a Scrypt based pool even though it outputs Bitcoin to users.

Basicallly you're trying to fit a square peg in a round hole.  Not gonna work.

You should be using that USB miner to mine on BTCGuild or a Bitcoin P2Pool node.

Get cgminer 3.7.2. Use --scrypt option. Run from windows command line ("cmd") so you can capture any errors.

Are you trying to mine here with a Block Erupter?

That's not going to work for him... he's trying to use a USB ASICminer Block Erupter on Middlecoin.

Undervolting via cgminer rarely works. You can use MSI Afterburner in Windows in order to check if the voltage control is unlocked and can be controlled by software. If not - you'll need to flush you GPUs' BIOS in order to unlock. This is potentially dangerous since that might brick your GPUs.

As for the hash rate - you'll need to play with thread concurrency, engine/mem clocks and other parameters for your specific cards in order to find a sweet spot.

No. You really should do a bit more homework. Seriously all the information that you need is in these forums. Use the search button.

Like I said in my other post above...

It won't work with ANY Scrypt based pool.  Only SHA256 based pools for mining Bitcoin (and other compatible coins) directly.

We have explored that topic a lot in the past weeks.

Have a look at this thread about
(A) optimizing with stock voltage,
(B) undervolting, potentially with your own modified BIOS, and
(C) undervolting and underclocking to a certain sweet spot


The reason for doing this is NOT to blindly increase the khash/s. But to save money by using much less electricity.
(C) results in amazing khash/Watt efficiency:  Almost 3 khash/Watt for the whole rig, and 4.0 khash/Watt for the GPUs only.

Very important for people in countries with high electricity prices, and those mediocre weeks with low coin output.

I suggest to jump into posting #37 now - but if you want to try, please read the whole thread. More reading, but less tears :-)

This is potentially dangerous since that might brick your GPUs.

Exactly. That's why I like the VBE7 approach, to not just flush any other BIOS, perhaps even from a different vendor, but to use the original BIOS, and just tweak 3 values.  Posting #45 gives such a BIOS, and how I created it.

Still, there is enough danger left. Do it at your own risk - and not in all of your GPU cards at the same time.

Happy mining!

Can I ask how you work out the kH/Watt for the GPU's only?

Sure.
(g)pu (d)isable all cards, then measure the remaining (in my case 81) Watts, and subtract that baseline everywhere.

It's not exact, an idle card still uses a few Watts, perhaps even only single digit - but compared to >200Watts, it's only ~5% wrong.

A discussion of that topic is in posting #72. Come over if you are interested.

Do you know if there a thread for the R290X also, looks neat, and must try to optimize my rig soon... :-D

[Damnsammit]

So I guess Scrypt ASICs are out... not sure how I feel about that.

How is this proof that the scrypt ASICs are out? I am just curious. Isn't this the same person we suspected to be running a botnet or a GPU farm?
