Topic: how to underclock GPU ram (Read 3668 times)

ohh

it's unnecessary for hashing and generates significant heat.  you can underclock memory to get a higher core without affecting temps

why underclock memory?

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%

so does anyone have the exact steps to do to underclock with AMDOverdriveCtrl?  that would be awesome help for linux noobs..

looks like i needed

sudo apt-get install libwx-perl

I don't know what version you need, and I'm on Ubuntu LTS:

$ sudo apt-cache search wx | egrep -ai libwx

The AMDOverdrive needs wxWidgets or so it says in the configure file.

what package is that in?

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

AMDOverdriveCtrl 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).

I'm seeking a way to underclock the ram on a 5830 and 5830 at the command line in linux.

any ideas?
