Ok this is what i did.
i used atiwinflash 110 to make a backup of my current firmware
then i used HxDen hex editor to modify the backup i just made to unlock the pipes.
ok done now i have a working *.rom file with pipes unlocked.
then i used RaBit 2.1 to edit the backed up rom file, got the error , kept on going, and modified the voltages.
set gpu to 1.225 v and left clock speeds default, which is 520 gpu 1000 ddr-3
ok saved , done
**** notice at this step make another backup of the original firmware**** and save somewhere
time to flash
then i used atiwinflash 110 to flash the backed up modded firmware to the card
screen went blank....... desktop came back up. after 5 seconds or so
looks like it worked, rebooted
checked atitool and shazaaaam 16 pipes
i used a the newest RIVATUNER to set the fan speed to full.
next i used ati overclocker 3.70 to increase the ddr-3 voltages ( it can also raise the gpu voltage ) both in realtime, that means it raises as you move the slider
used atitool to increase the gpu and ddr-3 speed
final oc at gpu = 1.250 core volts
final oc at ddr-3= 2.5 core and i/o volts
650 gpu @ 16 pipes
idle @ 45 c
ALERT **** be carefull with Rabit , not to change the ddr-3 latencies , i did it by accident, so dont click the realtime box under the memory tab in rabit
again NO NOT click the realtime box in rabit under memory tab
if you do, don't make any changes and exit rabit
or it will mess your performance up bigtime
and i mean bigtime, it changes the ddr-3 latencies all of them.
so once again double check you ddr-3 timming against the unmodded backup of the stock firmware to verify default/stock ddr-3 latencies
i am betting money that with the right ddr-3 latency timming and voltage I could get this card alot faster especially with a water cooling system
around 750 gpu and prolly around 1500 ddr-3
but its just a guestimation
well there it is
every thing you need to unlock the REAL power of the HIS gto iceq 3 turbo video cards
