Works fine on my R9 290 cards.  Using 14.6RC2 and the 6/25 sgminer nicehash build in Windows 8.1.

Yes.

Also, I had to use Display Driver Uninstaller from Guru3D to dislodge this driver from my PC.  Simply uninstalling it and re-installing 14.4 did not replace the OpenCL file with the 14.4 version, so I still had HW rejects.  This is fairly typical of AMD drivers though.

Only if you are lucky enough to be able to get 1500 memclock.  If you have crap Elpida memory that won't OC above 1400mhz like me, just use stock mem clock and I 18 for 3700KH/s (and probably less power usage).

After moving to 14.6 got an error starting sgminer saying my TC was too high.  Worked fine on 14.4.  Deleted bin, same error.  Decreased TC a bit, it started but all HW errors.  Going back to 14.4.  This is on reference R9 290 cards.

You forgot a couple .dll files, but this version seems to work great for me.  Using same config I used with the 2% fee miner the hash rate is maybe 0.020mh/s less (not a big deal).

This still seems to be crashing my driver instantly on my R9 290s.  The 2% one has never crashed the display driver with the same config so idk what's the reason.

This release is bad for 290/x owners.  Something is obviously different between this and the 2% fee miner, because this one crashes at intensity above 15 and the 2% fee one did not.  Unfortunately, I cannot use anything above -g 3 without getting Error -4, so I need the correct intensity setting to work to get a decent hash rate.

That makes this miner bad for 290 owners until the author fixes the intensity bug.  You will not get the 3.7mh+ on this miner until it is fixed.

My profits are up and my pool is reporting the same hash rate as the miner.  I don't think it's a scam, just a developer who doesn't mind breaking the GPL.

ccMiner increased X11 hash rate at least 100% by now and power consumption is maybe 20% higher at most.  You can get an increase in hash rate without the same increase in power usage by optimizing the code.

Hash rate on my 6x R9 290s (reference design, all elpida memory, all running stock mem clock and minor core OC at 1000mhz no volt mods, catalyst 14.4):

Original sph-sgminer:  2450kh/s  rejects ~1.5%  watts 415
2% fee miner w/ same config:  3075kh/s  rejects ~1.5%  watts 390
2% fee miner w/ below config:  3725kh/s  rejects ~1.5%  watts 425

Above watt ratings are for the 2 card rig.  Temperatures are still "ice cold" compared to what reference cooler R9 290s do on scrypt.  Not worried about my fan bearings going out trying to keep the cards cool.

Very minimal increase in watts from old sph-sgminer for a big increase in hash rate.  My cards are very underperforming R9 290 cards compared to average and don't OC well at all, so people with better OC will probably be able to get even more hash rate.  For me the main secret was lower intensity to 18.

My config is:  -w 128 -g 2 -v 1 --thread-concurrency 20482 -I 18

I'm using CGWatcher so that might have something to do with it.  I took all of the DLL files out of the DLL folder and put them in the folder with the sgminer.exe (or else it will give errors).  My sgminer.conf is also in the same folder as the .exe.  Don't use the useless batch file it came with.

For people using the 2% fee miner with reference 290 cards (elpida memory in my case), here is my setup getting ~3.7MH per card with low rejects:

This gets me 3.1MH/s, same as -w 512 and -g 1.  -g 4 does not work (Error -4 on both rigs).

Edit:  This is on a reference 290.

Yes.  The 750Ti can get 1.8-2mh or even more on X11 for only 50-60 watts.  On scrypt it did between 300-400kh.  That is 5-6x the scrypt mining rate.  My R9 290s do 2.47mh on X11 which is roughly 2.9x what it got for scrypt mining and it uses ~180 watts per card.

Basically the 750Ti is 3x as efficient as the R9 290 at current X11 mining rates and power consumption for those cards.

I also noticed there have been nearly no updates in the repo for a month.  I really do hope someone is working on an AMD optimized miner cause this is ridiculous how inefficient this is vs the 750Ti.  Otherwise X11 will soon be unprofitable to mine on AMD.

BTW, 14.4 drivers got me a miniscule bump in my X11 MH (2.410 on 13.12 to 2.470 on 14.4 for my 290s).

We really do need an AMD optimization really badly.  My friend has 750Ti rigs and he is getting over 2MH on each card for about 50 watts per card with ccminer.  My R9 290 does 2.5MH for 200 watts.  Looking at how the 750Ti does in regular scrypt compared to the 290 there is definitely room for optimization here.

Otherwise its probably cheaper to sell all the AMD cards at a loss and pick up 750Ti cards.  They are over 3x as efficient right now.

Well, I can lower my intensity to 19 and get a hash rate that is about 13kh/s less.  I'll test it and see if the improvement in rejects is worth it.  Thanks for the info.  I may just have to live with the rejects if this doesn't work out.

I don't understand how that's an intensity problem when it is fine on other pools, though.  These are R9 290 cards and they are running at I20 like everyone else runs them at.

I tried mining here but my rejects have just been creeping up to the point where it is not worth it.  Started at an already high ~5% for the first few days, almost 8% now.  Was getting ~2% on Wafflepool.  Add the lower Waffle fees in there and I don't think the profitability is higher enough (or really at all) on this pool to make up for that.

Also tried sgminer like someone here recommended but I got the same reject % with less kh.  Guess it's not the savior of mining programs like they made it out to be.

They actually fixed my issue right when I posted here.  There's been no one on the support IRC for the past couple days when I've been on, and they can't look at specific accounts there anyway.  I trust Cryptsy, and it was never in doubt that they would resolve the issue for me.  They have always come through in the past.  I just wanted to get it fixed in a reasonable amount of time, and I am grateful they look at the forum here to take care of things like this.

And I agree, people expecting everything to happen within seconds need to take a chill pill.

Thank you.  I will update the support ticket.

cthulu1:  I assure you I did not make any mistakes to cause the deposit to show 0 confirmations on Cryptsy's end.  I do not have any Cryptsy hate either.  It is frustrating to have thousands of dollars worth of cryptocurrency in limbo for days and creates a stressful situation for me.  My only beef with Cryptsy is the support response time.  I posted here and it was instant, and I am happy with that, but I would have been happier if I did not have to post here at all.  I don't expect instantaneous withdrawals or deposits, but over 48 hours is quite a bit too long.
