i wont give up Wink

so let me burn my 7970 @ 1.2 - 1.3 ghz

Sure but then we'll run a 290X at same clock and still be 36% faster :-) It's essentially the same hardware but more cores.

yar. and the 290X has more overclocking potential since it is designed to run much hotter (95C target temp!!)

Thank you! I got so much used to oclhashcat to choose automatically - lazy user - the best performance settings, I never considered manually tuning them. With the same -n & -u settings as the autotuned ones in the benchmark mode I get the same measurements for single hash. Mystery solved. Thanks again for the hint.

Cheers,

Hi Epixoip,

First and foremost thank you for your od6config tool, it has been a life saver thus far.

I was wondering, do you plan on updating it so that we can manually set voltages? I'd like to undervolt my card some but can't figure out how to control the voltage via linux, nor how to monitor what the current voltage is set set to. If anyone knows a way to get voltage control on 290x's under linux please show me the way.

Again, thanks for the great tool! Wish it could also control 270's which I'm having trouble overclocking with amdconfig.

there is an open ticket on od6config's github to add voltage control. it's easy to add, i just haven't found the time to do it.

Perhaps you need to put up a bounty. This is so necessary I'm willing to donate!

Try my fork at https://github.com/magnumripper/od6config - NOTE I could actually not test it from where I sit right now but it just might work...

If/when we get past any teething problems I'll make a pull request to epixoip.

Thanks for that. Just installed your branch and get the following when I run the get voltage command

Code:
allmines@server:~/od6config-master$ od6config --get voltage

Adapter 0: AMD Radeon R9 290 Series

    Core voltage        : 0 mV (default)

Adapter 1: AMD Radeon R9 290 Series

    Core voltage        : 0 mV (default)

Is it normal for it to show 0 mV as the default value?

Nope :-) I'll be back after I get access to a test host.

Edit: It *might* be that the code is correct but the figures are relative (so your output is sane!). So "--set voltage=5" will bump the default with 5 mV. See https://litecointalk.org/index.php?topic...4#msg94244 (btw undervolting - using a negative value - is allegedly impossible due to a bug in 13.12)

Documentation is scarse to say the least. I found this - unanswered - thread: https://devgurus.amd.com/thread/168096

Edit2: I won't update here anymore, see https://github.com/epixoip/od6config/issues/3 for how this emerges. Anyone having clues, please chime in!
