Maxcoin -- Time to take the crown back from NVIDIA

[finnjaevel]

Have you noticed that your WU is extremely low when mining Maxcoin with modified cgminer ?

I had WU of ~80 on my R9 280X when hashing @360MH/s. I fixed the kernel and now WU is ~1300 !!!

Here is an optimized and corrected kernel:
https://anonfiles.com/file/4507f9f7232f2c1f8a8f8d3762528740

Instructions:
- Save/Backup your keccak130718.cl file if things don't work as expected...
- Overwrite it with the file from zip
- Delete all *.bin files (in my case keccak130718Tahitigv1w64l8.bin)
- Restart cgminer and go for it !

With the updated kernel I had to lower the intensity to get rid of the HW errors. Now running with I = 10 and WU hits 1300!

EDIT: These changes do not give much benefit. In most of the cases only WU-meter is affected.

I looked at the changes you made (4 lines) and it's not increasing anything except the number that is displayed.  I'm not sure if you actually believe that there is any improvement or you just posted this in hopes of people seeing a bigger number and would send you a donation.

Impressive.  Posting source code is good enough for some, but those that can read it can see if it will really work as advertised.

can also confirm this, does nothing

This is the first scam that made me laugh

to bad maxcoin is a joke and a scam

The last time somebody tried something this lame was when Realsolid released his Solidcoin miner with inflated hashing values!

That sounds interesting, can you throw us noobs a link?

thanks god. I scrolled down before I copy the max address.

Embarrassing indeed, but last night I really thought I found the holy grail 

I had no intention of any kind of scam. Maxcoin seems to have a lot of scams going on so I understand your input based on that. Thanks to your replies I ended up doing more research instead of just hasty conclusions. Let me explain...

When miner is started it gets low difficulty/target values from pool. The current kernel discards the lowest difficulty (diff < 16) shares and some valid shares are lost because GPU kernel does not report them. With my changes even those easy (high probability) shares get reported. So one can actually benefit of those changes. This is also the reason why I first thought I had found something really good. It does not only affect the WU-meter. However, a modern GPU gets diff >= 16 difficulty from pool quite fast so it is very true that in the long run with a proper pool (not always disconnecting) my changes do absolutely nothing. Those changes could give some benefit if you had a really old GPU and the pool difficulty stayed low.

So thank you guys for pointing out my newbie mistake. I learned a lot.
