@PhoenixMiner:

you use my GPU kernels in your "fastest" miner, 100% match of binaries. I can prove it if you are not going to confirm it.
So do you confirm it?
   No, we certainly DO NOT confirm it. We believe that you've tried (and apparently you think you succeeded) in extracting our kernels using reverse engineering techniques. That wasn't very nice of you to say the least but we have expected something like this, just not that fast. In some sense it is flattering but also a little annoying.

   The first version of our kernels was obtained from someone on this very forum for quite a bit of coins. They were a little bit slower than the best miner on the market at this time - yours - but we decided to use them to jump start our project anyway. After a lot of tinkering with Polaris GPUs we found out how to increase the speed a bit and improved the kernels a lot, achieving higher speed and/or lower consumption than your miner (in most cases). The original versions were left as a honeypot for particularly persistent reverses which apparently did its job quite well Smiley

   Now, are these old kernels the same as old versions of yours? We don't know for sure but we doubt it, and we can't just take your word for it (especially after throwing accusations like this after basically admitting that YOU are trying to reverse OUR miner), and because they were slower than your miner, and they do not support dual mining at all (and dual mining is still the killer feature). But even if they were, frankly this isn't our problem - we've paid handsomly for them, and we haven't used them in any of the publicly released versions, so we won't lose any sleep over this. If you beleive so, search for a digruntlet employee, or perhaps your unnamed source(s) at AMD?

I decided to check your miner as soon as I noticed that you have same tuning option ("+" and "-" keys in runtime) that works exactly as my -dcri option, also your miner has no "optimized" kernels for same set of chips as my miner. After checking I found 100% match in GPU kernel on GPU.
Now you are talking about some "old unknown" kernels and you don't use them anymore and have super-protection that can fool me and so on... okay.
I will create step-by-step guide how to confirm that you send my kernels to GPU and you will say that your miner uses "old unknown" kernels because it detects dumping but still mines at the same speed. That's funny answer, but you don't have better one, I understand.
So my word against yours. The result is obvious for me, however, since I call you a liar, anyone who wants to confirm by yourself that this miner uses my kernels can PM me and I will send step-by-step guide how to do it, then you can say the results; no newbies please, be at least sr.member on this forum, just to be sure that you don't want to become another "phoenixminer" and spend my time again...
