Hi everyone, I hate to ask this question when it could be resolved with plain old trial and error, but it is extremely hot in the building where my rigs are kept and the last time I went out there for maintenance I was nearly roasted alive.

I have 6 card rigs with modded bios 480's/470's; win10 64; 16.9.2 drivers; watttool 0.92; and claymore 9.3
I want to use the latest AMD blockchain driver, and claymore 9.8 but I've read mixed reports of whether or not clock/voltage control is possible. Some have said watttool works now, others said that it looks like it works but doesn't actually change clocks/voltages. Folks are saying the same thing about the latest beta release of Afterburner (It works; It doesn't work; It looks it works but doesnt actually change anything...etc).

Can anyone with a similar setup please confirm that clock/voltage control is possible, and do I need pixel patcher for modded cards?

Thanks!
