I need to look further into this, based on some friendly and some not so friendly input I may have stumbled on an unfair exploit. I'm not sharing an unfair exploit. Thats that for now.

if this is for real, which I highly doubt, what you should do then is buy as many GPU's as you can and dont tell anyone about it  ;)

and if you must sell this secret, well, you should find a senior member with a good trust reputation that can verify your claim

well, if you must sell this secret, well, you should find a senior member with a good trust reputation that can verify your claim, that would go a long way if you want to convince others this is for real and this really works, you know kinda like the scientific peer review process

Could it be only usable for the 5770's? or does it have to do with the program / pool?

Ive a 5770 mining. If you want I'll try whatever it is and corroborate your story. Not a hugely regular poster on here so obviously up to you whether you trust me or not.

essentially you're asking how to monetize software that was given to you for free... classy

Why does it say 5700? Thought you had 5770's, driver issue? Looked up that 5700's only get around ~100 khs. Seems kinda fishy now, you should have someone with good trust try it

Sorry to hear that. If I discovered a sure thing, I would scrape together everything I could to purchase older, less efficient mining gear and host the miners with friends and family. Best of luck in your endeavor

I have a 1.5MH rig mining on middlecoin right now. If there was some way to split the earnings generated from the excess hashpower that would be win-win

For reference, I have a R9 280s, and Catalyst says 200. I have the latest stable drivers. I think the drivers are designed for a series, rather than a specific card. So it means 57xx, or 2xx, essentially.

Nothing to worry about.

What the hell did i just read....

This thread went full retard.

Aren't you the same guy looking for charity donations?

Highly suspect.

Is it a hardware tweek or a software/code tweek?

My Nvidia registers all the numbers :/ my bad. If this turns out to work and someone DOES donate, whats stopping them from using what you told them to resell and so on? I'd just keep it to yourself and everyones happy :)

There's a bug in some pool soft which counts INvalid shares as valid shares, since it's very easy to produce invalid shares and you are able to produce them at much higher speed, this is what he does.

the problem is, you're stealing from the other who mine in the pool as you're share rate is displays higher than it really this thus giving you more from the block than you deserve.

good pool ops see this immediately and ban you from the pool (freezing your earnings until then) and fix their pool soft so nobody can do this again.

I know what he's done, then. Changed the algo from scrypt, right? You can submit invalid shares very quickly by using a different algo.

I'm not a real miner, I don't even have a AMD card or a Desktop PC, but I tested some tweaks for CPU miners on my notebook and got 10 to 15% increase in my hash power using AVX2 instructions.
Not very good for cpu, I know.. :-)

But I have an idea: If you can code your modification on cgminer, why don't you compile a version with your modification and a hardcoded mining pool for DOGE with your login and password. I mean, create a version that will only mine on your account, don't accept address, login and password input, and give the compiled file to people on the forum to test it. This way, your secret is mostly safe and you will be able to test this tweak on different GPUs.

I, my self, cannot test, unless this work fine for a mobile Nvidia card too, but I'm sure a lot of people will give a try.

Cheers,

great.  that does nothing to benefit the currency at all, and doesn't represent any real-world improvement on hash rates.

If what you're saying is true, this merely takes advantage of a fault in some versions of existing software, and doesn't improve the hashrate of the physical hardware the way the OP implied it was.

guess where the currency comes from to fill this guy's wallet? From the other pool miners who paid hard earned money for their hardware. 

If op is just showing off a software hack, he is a parasite telling us he's getting a free meal.  

Just think over it..

There is no way of "tweaking" a 5770 to a 7970 :-)

Its simply an "exploit"..

It was used before on many, many pools, many people tried in on my pool too weeks ago.

The OP is just the first one who posted about it on bitcointalk.org

There is a issue ticket @ the stratum software from me already some time ago.

Maybe its good, so the other pool ops are forced to update their software.
