When asking these questions, you need to give a little more information. What cards? OS? driver?
Ah right
7970s / W7 / Catalyst 12.2
First, I'd update to
12.8.
Second, CGMiner can only clock the memory 150MH/s below whatever the core is running at. My 7970 runs at a core:1180, so CGMiner can only clock the mem to 1030.
However, MSI AB can be tweaked to lower your memory to whatever you want. You need MSI AB 2.2.3, but you need a DLL file from 2.2.1. See this
thread for more information. I run my 7970 at core:1189 and mem:375. I could go lower, but I lose hashrate if I go to low on the mem.
file is removed. Do you mind reuploading?
Nvm I downloaded from here
here is the 12.4 dll if anyone needs it, took me forever to find it
http://www.multiupload.nl/0BWAFN4UGMWhy does my first card crash (don't even have a monitor installed) when I lower memclock?
edit 2:
I think 12.8 fixed it but I cannot lower memclock below 685 in MSI Burner. When I set in config to = 2 the bars disappears. Yes I did put the dll file in there ;/
edit 3:
wait it's still at 1375 fml ...
