what exactly does the -g flag do? I can't seem to find it in the --help

again with your settings my display driver crashes, but if i set it to g1 then it goes just fine but only at about 550khash

with my settings g1/g2 didn't seem to make any difference (edit) before it didn't that is ... now with the 13.8 driver g1 crashes my setings, but g2 works

so for now with 13.8- your settings g1 works g2 crashes, my settings g1 crashes g2 works

The -g setting is how many gpu threads to start, if you have only 1 gpu then -g1 with a TC of 64 * bit-width (or slightly less for me) or -g 2 with TC of (64 * bit-wdith) / 2 should be used, if you have a 7990 then -g 2 would be best, there is probably better settings but if i got a 7990 i would first try -g 2 and --thread-concurrency 16384 (i think the bit-width of 7990 is 256, i could be wrong though).

so if i run it with g2 in the command line but i have gpu-threads 1 in my conf file, which one take priority?

i should probably go change that...

honestly I don't know but i would think that the command line args should supercede the config file args, at least thats how i would write it, so incase you forget you have something in config files you forgot about it would be overridden with whatever you have in command line as you must want that argument you set in the command line to be active since you typed it there while config files can be old...

but again just a guess.

having exactly same problem like what happened to ronaldinho_07, two 7990 consumed between 1.1 and 1.2kwatts but basically it must less than or equal 1 kwatts with effective added

I get about 680 with my settings.... can't seem to make it do any better. when I tried your settings I only got 550.... only difference is driver version though

my 13.8 driver installed and seems to work fine, but I got a failed package error during the install. video transcoder. I don't think it should affect anything but I am going to play with it and see if I can't make it install without any errors first

nah,you only need to install amd driver...otherthings should be ignored.
i13 tc 8192 g2 ,nothing more
3-4 hours ran

if I could get your settings working I just might take that 660 hashrate so I won't need a new psu!

850w... that's crazy Grin

damn that's pretty nice looking... wish I could get mine to run like that Wink

might revisit the 13.8 driver if I find the time

an other tweak,taking a look at rejected rate Grin

1050/1250/1.08volt ~ 105x-1100W whole system ~ 730
950/1000/0.99volt ~ 850W whole system ~660

tempurature also decreases

i've just tested other 7990s
Config: Win 7 64bit+amd 13.8 beta2 driver+Cg 3.1.x
1050/1250 1.08voltage

yea... not so much... everything i try with tc 8192 either runs real slow for me (1-1.1mhs), spits back hw errors, or crashes the display driver

so i will be sticking to 1.08v tc 24000 i 20 g 2 w 256 core 1090 mem 1500 for 1.365mhs at 83/74 degrees

was hoping to get over 1.4mhs with this card but i guess it's close enough Grin

well, i downloaded the 13.1 package from 4 different spots and none of them would allow me to install a display driver, same thing with 12.11beta. i installed 13.5beta and tc 8192 works but only at i 13 and low core/mem clocks. even then it is much slower than my previous settings. i will play around with 8192 a little bit but i think my original settings are gonna be best for me.

nope... no drivers to be had. it offers to install hdmi audio, vision control center, sdk, but no display driver

now this is getting on my nerves lol

did you get any better results with other clock settings yet?

format and fresh install of windows, still 13.1 package won't list the display driver as an option in the custom installer. can either of you share a link to where you got a working version?

try removing the video cards in device manager then add them back.

The temperature was slowly creeping up to high.

GPU 0 - 73.0C
GPU 1 - 79.0C
1.29 Mh/s average after 7 minutes

MSI Afterburner Settings:
Core Voltage (mV): 1100
Core Clock (MHz): 906
Memory Clock (MHz): 1000

Do I just keep changing the values around till something works?

those are a little high but not too high. basically, yes... take a look at other setting for 7970 and go from there

at 1080v core 1090 mem 1500 i was getting 1.36mh/s with temps at 83/74 stable

it can also be tough to make sure the voltage settings took / you got ulps disabled properly, for me cgminer wouldn't report the cards voltage correctly but i knew because temps would go down using the same settings. just play around with a few different numbers for a while and see how your card reacts, then narrow it down to what works best

~~for some odd reason 13.1 will not install.~~

never mind i had to reboot again that was really odd

i am having the same issue, rebooted several times, uninstalled ccc, manually removed files, ran driver sweeper, rebooted in between each step, disabled AB... for some odd reason 13.1 won't even give me the driver as an option when i use the custom installer.

i just set up access to all my games and downloaded one... plus the blockchain i realllllly don't wanna download again, but it looks like i am gonna have to format and try with a fresh install of windows
