Will this allow me to get past 900Mhz on my XFX 5830 and 875Mhz on my Sapphire 5830? I'd love to get to about 950 on each card if possible.
I use Catalyst 11.6 to drive my 5830s at 990/600 (308Mhash/sec). These are Sapphire cards, your milage may vary on XFX. This is at stock voltage.
The commands I use in my startup script are:
#Overclock GPU to 990Mhz
DISPLAY=:0 aticonfig --od-enable --adapter=all
DISPLAY=:0 aticonfig --od-setclocks=990,600 --adapter=${1}
Where $1 represents the adapter # of the GPU.
