I emailed them with this a few weeks ago:
I'm running two radeon 5830's however I have found no way to successfully
modify voltage, clock or memory on both cards, just the first one...this
is an extreme disadvantage since in MSI afterburner at least I can do both
cards, but if I want to slightly modify voltage on both I have no way of
doing so. Is there anything I can do to change both cards voltage and
clocks using Trixx? This would help me a lot as I am able to overclock
this card highly, I just need to be able to do it on both of them instead
of just the first.
I went out and bought a crossfire connector but it still doesn't work on
both cards even with crossfire enabled.
Today, I got a response that some of you might find exciting:
Enjoy!
Thank you.
