OK WOAH! I got it to work, didn't realize i needed the conf file in my AppData\ROAMING directory... now I need to figure out why I'm only getting 22MHs/s on an R9 280X GPU.... says the worker is getting it done... but that rate is really low... anything in my conf file that i should modify to step this up?

Yep - your intensity is insane low. I'd use 1024 with this minter.

Ok sweet, that stepped it up... I'm at about 90 MHs/s now.... is that about right?

That didn't do anything, but i set it to 0,256,2048 and I get about 135 MHs/s

I'd make it a multiple of 44.

Ok I will mess with some of the settings. What hash rate should I be hitting with this kind of GPU? It's a pretty high performance card. If none of these settings work, what else could be the issue?

I'm not sure what you should hit with it, probably 250MH/s or so, maybe a little more. I've noticed this minter to be slightly... tempermental. Not sure if it's my personal edits to it or not, but I've had my 290X suddenly lose 100MH/s or 200MH/s on reboot for apparently no reason.

Nice so I'm running at about half speed, nothing I do seems to fix the issue. Think I'll restart maybe mess with the voltage settings on the GPU in catalyst

Won't help unless you up the clocks. Voltage does nothing for speed - it only makes overclocks more stable, at the cost of more heat and power usage.

Ah heard I shouldn't overclock this GPU anyway... I'm out of ideas, what do you suggest. I can't seem to get past 140

Like I said, I haven't used that minter much - you may want to look through this thread, though - I've seen others posting their settings.

500MH/s on a 290X is hard to get, but I'm fast approaching it.

You've been such a great help. I owe you for sure for all your help. Do you know of a more stable or better performing minter for windows users that do keccac?

Not really - I've heavily edited this one to get my results.

Doesn't matter where the minter is - it's about where the conf file is. I don't use Windows, but I believe it should be in %APPDATA%/.NxtMint - open an Explorer window and type %APPDATA% into the bar (literally) and hit enter, should open the folder.

To be precise, it's not in %appdata%, but in %user%\appdata. I have my appdata redirected to a ramdrive (K:\appdata) and found the config file not to work when I placed it there. Had to place in C:\users\username\appdata for it to work.....

There is no other minter for GPU afaik.

The settings I use to get 215 MH on a HD 7970 are:

gpuIntensity=512 (If I set it to 750 I get 220 MH, but GPU usage goes from 97% to 98%, and that's the difference between being able to watch flash videos in a browser without crashing, and with my display driver crashing)
gpuDevice=0,256

I overclock my card heavily. That's a whole other subject you had better google yourself. If you have a high quality card and good airflow in your machine you can increase your hashing power by about 25%, but expect lots of noise, heat (= more electricity), and of course lots of crashes and tinkering before you get it right. But that's the sport =)

But that's the sport =)

Well here are my settings right now.
Code: [Select]
#######################################
# NxtMint configuration               #
#                                     #
# Copy to the NxtMint data directory, #
# rename to NxtMint.conf and edit for #
# your configuration                  #
#######################################

# Set the Nxt node host as a DNS name or an IP address
connect=localhost

# Set the API port (the default is 7876)
apiPort=7876

# Set the secret phrase for the minting account (required field)
secretPhrase= my pass

# Set the 3-5 character currency code (required field)
currency=EGOLD

# Set the number of units to generate for each hash round (the default is 1).
units=100

# Set the CPU thread count (the default is 1).  CPU minting will not be done
# if cpuThreads=0.
cpuThreads=1

# Set the GPU intensity (the default is 0).  GPU minting will not be done
# if gpuIntensity=0.
gpuIntensity=1024

# Set the GPU device number (0, 1, 2, ...), the work group size and the work group count.
# The first GPU device will be used if this parameter is omitted.  This parameter can
# be repeated to use multiple GPU devices.  The GPU devices that are available are
# listed when NxtMint is started with a non-zero value for gpuIntensity. 
gpuDevice=0,256,1760
# Enable/Disable the GUI (the default is true)
enableGUI=true

I have also tried GPU intensity at 512| WGS at 128, 256 , 512 , 1024 | MANY different WGC in multiples of 44 | I've overclocked my card successfully from 1000 to 1150 Mhz and minting doesn't crash...

However these settings only allow me to fluccuate between 135 - 160 MHs/s

I also modified the mint.bat file
Code: [Select]
@REM Start NxtMint

@REM ###################################################
@REM # Rename to mint.bat and make any desired changes #
@REM ###################################################

@echo Starting NxtMint
java -Xmx1024m -Djava.library.path="jni" -jar NxtMint-1.4.0.jar

I modified java -Xmx256m to 512 and 1024 as well... i read about this on a different thread. None the less, same results. My driver has only crashed once when I didn't adjust the voltage high enough to support the overclock in GPU. Stable now but same speeds...

Make sure you have the latest Catalyst drivers, upgrading from 13 to 14 made my hashrate go from 150 to 220. Update OpenCL for good measure (made no difference for me but don't know which version you are on).

Also, I use version 1.3.0, not 1.4.0 like you do.

Great insight, I don't know why my instincts didn't tell me to try an older version of the minter. Great suggestions!!!!!!! As well as upgrade driver... sometimes I have driver conflicts, but I realized later that I found the reason and fixed it (I was getting atimpag.sys BSODs and had to delete every trace of it).

I am going to try all this now one by one see what goes on... I also have the newest OpenCL and SDK as far as I know... I will reinstall however. I will update ATI first, then open CL and try an older minter... I'm sure the link to 1.3.0 is available somewhere in this thread?

Some times you just need a second pair of eyes! Thanks for your input!
