Title: cant underclock under 900MHz Memory on ASUS EAH6870 Post by: Amaretto on July 14, 2011, 05:39:46 PM Hey guys,
i dont get it. There are so many posts where i read that you can underclock a 6870 to 300MHz Memory Clock to get the Temps down. Everytime i do this with MSI Afterburner it pops back up to 1050 MHz. He accepts everything till a downclock to 900 MHz everything under that will dont take any effect. Is there anything that i have to change in the MSI Afterburner tool or is it simply not possible with the ASUS card? Thanks in advance Title: Re: cant underclock under 900MHz Memory on ASUS EAH6870 Post by: heliosxx on July 14, 2011, 08:12:32 PM I have the same problem on HIS 6870. It seems to be locked to the gpu speed in some fashion as changing that changes the lowest minimum memory speed.

edit the msiafterburner.cfg file and replace the two lines: UnofficialOverclockingEULA = I confirm that I am aware of unofficial overclocking limitations and fully understand that MSI will not provide me any support on it UnofficialOverclockingMode = 2 Title: Re: cant underclock under 900MHz Memory on ASUS EAH6870 Post by: Amaretto on July 15, 2011, 10:53:56 AM oh nice,
will try this now. thank you! Title: Re: cant underclock under 900MHz Memory on ASUS EAH6870 Post by: ShadesOfMarble on July 15, 2011, 02:52:30 PM I found the solution, Isn't this mainly for OVERclocking the card beyond "safe limits"? Why should UNDERclocking be limitted?edit the msiafterburner.cfg file and replace the two lines: UnofficialOverclockingEULA = I confirm that I am aware of unofficial overclocking limitations and fully understand that MSI will not provide me any support on it UnofficialOverclockingMode = 2 Title: Re: cant underclock under 900MHz Memory on ASUS EAH6870 Post by: heliosxx on July 15, 2011, 03:07:46 PM You'd think so, but for me it stopped the exact behavior described here with the memory speed. I was able to underclock (and have it stick) to 575, then after restarting the app, down to 300.
