*** tried this now its running 1241 stock volts and 1320 at +93mv. What is going on?
EDIT - the voltage is quite high, 1.21v with DMM at stock (0mv) in LN2 mode, +50mv = 1.26v and +93mv is 1.35v. I didnt check v2.3.0 with DMM perhaps it doesnt apply higher than ~1.21v ?
1320mhz! Problem solved
Afterburner 2.2.3 was the last Afterburner version that allowed for native voltage control. With subsequent versions, the lines of code posted by elbubi must be copied and pasted into the config file before it'll be able to affect the voltage. So most just get 2.2.3.
your situation sounded wierd
Glad you don't actually have such a bad card afterall.
Stock on the unlocked 3A should be ~1.26v, and ~1.36v with +93mv . Yes, 2.3.0 doesn't adjust the voltage the same way 2.2.3 does until you do that config edit.

2) What increments do I increase Core Clock / Mem Clock by, and do I add them / test them separately, if so which do I begin with?
3) After finding the max stable clocks, what increments of vcore do I increase by?
Thanks, I don't have the card yet, just doing some prereading
Never hurts to do some research ahead of time.
1) You can check 'Apply OC at system start-up' on the main interface, below the profiles. And save a profile.
2) That's up to you, as far as the increment. I'd start by +50mhz the first time, and if that's stable then go up by 10 or 15. And it's a good idea to do the core and memory separate and
together. Some games you need a higher core, sometimes memory. And one max OC will affect the other (lower max stable core clock with a high memory OC). So, find max core at a specific voltage, then put it back to stock and test memory, then test both at the same time raising one at a time, finding the highest combo OC. That way you have a max OC for every situation (when you need a high core, when you need a high mem, when you want a combo of both). Do this for a few voltages (stock, +50mv, and +93mv) and now you've got multiple methods of attack at multiple voltages depending on the particular game
3) This is up to you. If you're crashing at a clock(s), you can raise the voltage to get a little higher. I just said find your max overclocks at +0mv, +50mv, and +93mv as an example, so that you have an overclock for different situations, but you could very well take the time to find overclocks for even smaller increments (oh and don't forget about the memory voltage too)Edited by dph314 - 1/1/13 at 6:14am
