If you insist on running the RX550 maybe consider ETC as it may well provide the best earnings.  The compute part of kawpow is going to be bad as you see about for the 550 but the memory is ok and etc is memory restrained.  The 550 will do 13-14mhs on ETC.  Which should make it the top performer for it.

How much are you guys making with 30 ethash in recent days?
Whattmine is saying high values, like $4,5, yet I can only get around $3,6 per day per 30 ethash.
I realize mining calculators are not perfect but the difference being so off is making me curious if others are making more.

Whattomine.com says 30mhs on eth = $3.76/per day without power costs.

Try using the 'Difficulty for Revenue" to Profitability 24h seems to provide the most accurate answer.  

Currently about $1.25 per 10mhs.

VERTHASH ALGO AVAILABLE ON TRM V8.2--

A new TRM is out, v8.2.  It includes new VertHash support.  An overnight run gave these results:

Mining VTC with 4X Nitro+ 4GB RX580 w/Elpida memory.  Clocks 1250/1870, hash 540kH/s per GPU.  Seems stable overnight.
I get some rejects, wheras mining Haven (XHV) I had near 0 yesterday with TRM 8.
Currently 26 rejects out of 1650 accepts, >1%

The straight-to-memory verthash.dat is a really nice touch.  But, I do notice that the monitoring feature for Claymore's EthMan does not work as it does for ETH mining with TRM.  I really like EthMan for my rigs.  It would be nice to monitor all my TRM rigs, even if TRM was mining Haven (XHV).

REPORTED AT THE CONSOLE--

The system (ethOS) reports slightly less than 120W per GPU.  I can't be bothered to take a wall reading, it would include CPU usage and rig fans.  I did try limiting the power to 100W per GPU with system utilities, but the GPUs dropped to a setting of 1175/1870 and the hash rate fell to  ~360kH/s per GPU.

I mine Monero with the CPU.

TRM DEVS CLAIM VTC USES LESS POWER--

But, for my 4GB cards no longer suitable for ETH mining, it is my top earner.  I am going to set up a rig with my 2GB Tonga cards and see how it goes...

--scryptr

It certainly seems to be easier on the cards vs some of the other algos.  Ive got it working on a stack of 1050's brought back from the storage closet.  6mhs on 2 rigs worth and a nice tidy profit per day. 

Really! Come on, you have done an awesome miner.
BUT. "Tonga gpus (R9 285/285X/380/380X, W7100, S7150) now supported for ethash and kawpow."
Thats good, but you just cant and wont do anything about hawaii gpus?
Its so funny when every other miner has support for Hawaii/Grenada, but then you dont. You, who advertise by your name to support AMD.
I have 3x r9 390, one RX 580 and one Vega56. I cannot put the Vega in my hiveos rig, because it works only with TRM.
Vega goes 54.2 MH/s with TRM, but yeah, no Hawaii support so i cant use Teamredminer. Then, for some reason, vega wont hash anything with any other miner. Only TRM.
All in all, i cant put my vega into my rig without hawaii support.

Such a big shame and gutted feeling, because i cant use your miner and my vega 56 because of missing hawaii/grenada support. They are good cards for eth mining, when biosmodded correct..

Hi, I'm using TRM to mine ETH using my Hynix Vega 56 and I'm getting 50.5 MH/s @ 130 W, which is about 10% better than PhoenixMiner 5.5c. Great! However, my RX 480 8GB only gets around 29 MH/s with TRM, whereas it gets 30.2 MH/s @ 61 W using PhoenixMiner. Is it normal for TRM to not be faster than PhoenixMiner for Polaris?

The RX 480 has optimised voltages and clocks, only VRAM tweak is REF=27.
