Underclocking 6870 Memory?

[humanage]

Anyone have the problem where they can't underclock 6870 memory? I'm having this in Afterburner, can't got lower than 575MHz, even with the unlock. :/ This just happened after re-installing Windows 7.

Single 6870's mostly have no trouble... sometimes you need to under clock the memory and then shut down msi afterburner and start it again... I think you might also need to add some lines to the MSIAfterburner.conf file.
My personal experience with 6870s (I'm running a couple of them right now) is that if you have more than one, you will need to flash the bios and use linux.
if you have a look at this topic I'm just about to add my report on doing so.

EDIT: looks like someone beat me to the punch. Regardless. the information is in that thread.

Do you have the hacked up CFG file for afterburner?

I edited my config file with the amendments to the EULA, but was never able to get my MSI 6870s to underclock below 575.

is it plugged in to a monitor, or does it have a dummy plug?
