Believe me, mmc code was changed and GPU mining was blocked. You can see this changes in mmc sources.

I spent the last few days going over all of the commits and merges made to the source code by Delinquency on GitHub. I went as far back as December 2013 and I found no changes to the algorithm or more specifically no changes to the implementation of momentum. I did find changes to the protocol with respect to difficulty re-targeting and fork handling. Delinquency also added copyright notices and changed bitcoin to memorycoin in all variables, functions, and file names. Additionally, I found significant updates to the Qt interface.

Have you even gone through the source code?

I also found the following post from Delinquency where he failed to confirm that GPU mining is no longer possible. He only stated that the pools supporting GPU mining for MMC2 discontinued it.

2 little questions to devs,

certainly not urgent but when you have time if you don't mind,

1) To compile are you using cmake or qt or what exactly to make the windows binary wallets you are distributing ?

I only tried to compile it 2x quickly the other day and got some weird errors , was using qt 4.8.6 i believe , with boost 1_55_0 , open ssl1.0.1j and the most recent qr code libraries and miniiupnpc. I was tied up at the time and figured I would have another go at it again this week.

2) Has there been any additional releases of open sourced miners with more optimizations /open cl support ect.. in the past few months. While I did not see any on the thread I still felt it worth asking. Thanks guys.

Windows Binary Libraries are compiled under nitrogenetic's tutorial. If you need help with the compile, you can post here.

The most optimized miner is closed source, by yvg1900. (YAM)

The only GPU miners that have ever come out were only supported by specific pools. Those pools have discontinued accepting shares for Memorycoin. They were closed source and only supported a specific amount of Video Cards (over 2G VRAM).

Now back to my original post...

But some of this clever guys (I don't know who exactly), was able to modify original mmc code to make it impossible (now) mine mmc with GPU.

The coding for MMC2 was not changed. If I remember my early months of 2014 correctly, the Radeon HD 7970 or Radeon R9 280X produced ~20HPM at around 350W. The i7-4770K initially produced ~3HPM at less than 90W. When yvg1900 released YAM, the i7-4770K jumped to ~13HPM. GPU miners simply could not compete with the power efficiency of CPU miners when they are between 2 and 3 times more efficient. AES-NI FTW!!! On a similar note, it is normal to see a dual socket Xeon servers pushing 40 HPM when using YAM. The problem right now is that all the default pools are down and YAM stops mining when it is unable to submit shares for the developer.

I think that the facts I have previously mentioned vindicate my original statement.

Additionally, I would like to add the following as further evidence concerning YAM's performance.

yvg1900 has made huge optimizations to the CPU miners - upto 400% on the latest processors, putting CPUs back on an equal footing with GPUs - more here

Yeah, the new CPU miner is better than GPU mining. I'm getting a 320% performance boost with my i7 3770k. Infact, my 3770k is outperforming my 7950 GPU, while using around 33% of the power. Amazing.
