r9 290 vertminer 0.5.3


I'm seeing about 300Kh

If I change the thread concurrency to anything higher than 8193 I get errors or it will crash.  I see folks reporting tc in the 20k range, but I can't move any higher than 8193.  Anyone know what I might have wrong?

I can get 800 Kh regular scrypt without any tweaking so I should be able to get around 400Kh here.

**Just noticed that at this tc, intensity higher than 13 throws HW errors.

6870:




It blocked my image, but I'm getting 2-3 kHash.  I get 300 kH with normal scrypt.

Note the extremely low speed.  I've tried many variations of threads, gaps, work and intensity.  The tc worked great on normal scrypt mining, but I've tried alternate values of that as well.

I'm having issues mining vertcoin.  I've been scrypt mining on a 6870 at 300Kh/s with these arguments:

-I 18 -w 128 --thread-concurrency 6720

When I tried moving to the modified vertcoin miner even with lowering the intensity to 12 (or even 8 ) I get nonstop:

(Too many invalid shares)

I don't see anything in the documentation that notes any other settings I should be using.  Is there something I'm missing?

I'm working on a Bitfinex android app that I'll be releasing open source shortly.  As of right now I can parse all ticker, position, and order data.  I'll be working on charts then buy/sell next.
