I finally took the plunge and upgraded to 7950. My plan was to enable unofficial overclocking mode in MSI afterburner like I've read in so many guides. I was planning to bump the voltage a bit and try going for 1050-1100 on the core. However, try as I might I cannot enable core voltage control.
I've been using this as my guide:
http://www.overclock.net/t/1196856/official-amd-radeon-hd-7950-7970-owners-thread/7110#post_16790928
This is what I've done:
-Uninstalled nvidia drivers
-rebooted into safe mode and ran driver sweeper
-swapped my GTX260c216 for 7950
-installed 12.7 betas
-installed amd app sdk
-installed afterburner 2.2.2
-downloaded missing dll's and placed them in the MSI Afterburner program files directory
-modified config file according to instructions in the MSI Afterburner folder
-modified config file according to instructions in the MSI Afterburner\Profiles folder
-launched MSI afterburner with xcl flag
-rebooted
-changed flags and mode to kernel
After all of this I still can't get it to work. I still cannot change core voltage. What am I doing wrong?
EDIT: I've been doing more reading and it looks like voltage control is not supported on non ATI cards? Mine is XFX, does this mean I can never get to control core voltage?
For clarity this is the card I got: XFX Double D FX-795A-TDJC I got that one specifically because it had 6+8 pin connectors which could indicate 7970 PCB, and because it had lots of outputs including at least one dual link DVI output. When I did research it turns out some cards such as MSI 7970 Lightning only had single link DVI outputs which is unacceptable for a card in that price range IMO. XFX card possibly had 7970 PCB and had the most flexible output of all cards I looked at, actually even though I cannot test it yet, but the box itself says it has two dual link DVI connectors as opposed to only one, so if that's true, that's a nice bonus as well. Plus HDMI 1.4a.
