So I'm trying to get my 290 and 290x setup. I've been tinkering with the settings and trying to be conservative with it still with no luck.

I'm using this following config...

Code:

setx GPU_MAX_ALLOC_PERCENT 100
setx GPU_USE_SYNC_OBJECTS 1
./vertminer --nscrypt -o stratum+tcp://east1.us.stratum.dedicatedpool.com:3367 -u 0ut1awed.1 -p x -d 1 --no-adl -I 15 -w 256 --lookup-gap 2 --thread-concurrency 24500 --gpu-memclock 1500 --gpu-engine 1000 --gpu-powertune 10

It will run on my 290 giving me a supposed mere 325Kh/s but the pool only reports 20Kh/s. It's probably because of all the HW errors I'm getting (I believe that's what the numbers tallying up next to HW are). When I run that same config on the 290x it reports back 900Kh/s to 1Mh/s but no accepts and doesn't even show it being up from the pool site.

I realize you have to fine tune but I feel like I'm already really modest in what I have setup.

What is the TC that it runs if you leave the --thread-concurrency part out (delete all .bin files and then pull the number out of the new file that it creates when you run vertminer again)? It should probably be greater than 24500 and it should run without any hardware errors at -I 15. It's hard to believe a 290 would get hardware errors at 24500 though - that's pretty moderate. There may be something else wrong.

If you get the new sgminer with nfactor support, (and maybe some other cgminer versions?), you can try a 290 at -g 2 --xintensity 4. I do that at --thread-concurrency 10240 and the performance is very close to that of -g 1 at high intensity, high TC. Once the clocks are optimized.

I'm on ubuntu so no bin files here. Not sure what the TC is on default but taking it out defiantly does not make a difference.

I figured out my issue with the 290x, it was missing the --nscrypt flag.

Still I can get neither to stop outputting massive hardware errors. I even tried backing down the core/mem clocks to no avail.
