is anyone using the Dollemizer firmware?
LOL I wouldn't trust anyone to provide a new firmware for any miner that says you'll make more.
You're not gonna make more - just they're gonna get money from you via fees or hacks in the miner.
Of course they also don't provide source code ... so you don't see the hacks that steal from you

... and they of course are breaking the license terms for not providing the source code.
If you do use it - mine somewhere else with it - I don't want to be dealing with people complaining about lost shares and problems here due to hacked miners
... or the pool losing blocks due to the hacks.
but if you have more equal miners, and you flash some of them, it should be fairly easy to compare and see if that would be true?
Also, with the improved mining algo, it should benefit a higher hasrate...
In other words: if a 13.5Th miner would go to 16-17Th and use less power, why would i care they take one or 2 percent of my mining hashrate? (all things being equal..)
Coz those figures are obviously fraudulent.
You really think Bitmain wouldn't advertise and sell their miners saying they do 16-17THs if they could do that?
... and again - regarding blocks:
So they've tested and proven that their modified code consistently finds real blocks on the Bitcoin network?
well i have to admit that i dont see the use of pushing out even more hash against many more watts, noise, heat, and shorter lifespan.
What i'm interested in, is the asicboost option,like dragonmint T1.
I can imagine that it might be a bunny out of the hat of bitmain, in order to re-sell their "new S9Tix"with asicboost support, to generate an attractive new model, and have a new income based on hardware they already developed and produce in large quantity. (in other wordt: why release it just right now as you already are as good as unbeatable...? You'd give away your pearls on forehand and have nothing in the magic hat anymore to compete...)
I think its a viableoption that has been "discovered" by an other team right now...
So, yeah. If they do well and it works: why not. (supposing your pool can handle it.)
