Title: how to underclock GPU ram Post by: warrensgun on June 03, 2011, 04:34:00 PM I'm seeking a way to underclock the ram on a 5830 and 5830 at the command line in linux.
any ideas? Title: Re: how to underclock GPU ram Post by: exahash on June 03, 2011, 05:23:11 PM AMDOverdriveCtrl (http://sourceforge.net/projects/amdovdrvctrl/) in batch mode. If you create a profile and call it profile.ovdr the command is: AMDOverdriveCtrl -b profile.ovdr
You can't overvolt with it, but it is the only way I've found in ubuntu to get memclocks below the overdrive range (aticonfig won't let you). Title: Re: how to underclock GPU ram Post by: V2-V3 on June 03, 2011, 05:37:58 PM I recommend using MSI afterburner to find a stable clock of your Core and Memory clock. you can than save to a profile and click on apply Overclocking on system startup.
There is a guide available here: MSI Afterburner Overclocking Guide (http://bitclockers.com/forums/index.php?topic=5.msg6#msg6) Title: Re: how to underclock GPU ram Post by: warrensgun on June 03, 2011, 06:25:50 PM The AMDOverdrive needs wxWidgets or so it says in the configure file.
what package is that in? Title: Re: how to underclock GPU ram Post by: twitcoins on June 03, 2011, 07:00:36 PM I don't know what version you need, and I'm on Ubuntu LTS:

sudo apt-get install libwx-perl Title: Re: how to underclock GPU ram Post by: itsagas on June 03, 2011, 09:53:33 PM AMDOverdriveCtrl (http://sourceforge.net/projects/amdovdrvctrl/) in batch mode.

Title: Re: how to underclock GPU ram Post by: oyster2000 on June 03, 2011, 10:03:14 PM AMDOverdriveCtrl -i
this will list each GPU by "active" AMDOverdriveCtrl -i 0 will bring up the GUI for the first GPU so you can tweak settings and save a profile. i noticed this also gives faster fan speed than aticonfig at 100% Title: Re: how to underclock GPU ram Post by: brunoshady on June 04, 2011, 12:38:40 AM why underclock memory?
Title: Re: how to underclock GPU ram Post by: Freakin on June 04, 2011, 12:42:15 AM why underclock memory? it's unnecessary for hashing and generates significant heat. you can underclock memory to get a higher core without affecting temps Title: Re: how to underclock GPU ram Post by: brunoshady on June 04, 2011, 12:43:28 AM why underclock memory? it's unnecessary for hashing and generates significant heat. you can underclock memory to get a higher core without affecting temps ohh |
