Definitely set any settings for voltage / clocks with 3rd party (vendor) apps (eg. MSI AB, Trixx, etc) BEFORE you start mining.
If you are changing those settings while the GPU is under load at best it will crash or at worst it might brick your card.
Please be careful and monitor temps closely, remember that pushing the voltage/clocks can permanently damage your card.
Topic: 7950 and VDDC (Read 1003 times)
Hello Guys!
Have done some tweaking on my 4x7950 rig (mining LTC) today and had some troubles.
I got 2x GB 7950 WF3 now on F43 BIOS, hashing very nice
(660kh/s avg.)
The two other cards are MSI 7950 TF3. They are very hot (kh/s/W also bad). So i wanted to undervolt them with cgminer (3.1.1) but it didnt work. Tried it by cfg and setting it manually in cgminer.
The way to go is with MSI AB I think?
How should i set the voltage? Before or after I start cgminer?
Thanks for a little hint
