Overvolt a 7750 ?

[DigDog]

So AMD doesn't want me to up the voltage on my 7750; probably because they don't want to make the £130+ cards redundant, though they do let you OV the 7770 (way more expensive) through Afterburner or TriXX.

here's a couple questions if anyone has had any success squeezing out any more powah out of this little card.

1) my mobo lets me pump up to +0.3v(i think ? or is it 0.2 ?) on the PCIE slot; since this card takes power from there only, i assume it's ok to just go and max this out?
also, should i change the pcie frequency at all ? (you know, 99/100/101/102)

2) is there any external utility (such as trixx or afterburner) that allows OV straight from software?
this guy http://www.overclockersclub.com/reviews/sapphire_7750_lp/4.htm on a Sapphire (i'v got a XFX Core [read "cheap"] edition) managed to get 1200 on the core and 1400 on the memory.
frankly, i'd be happy with 1100 core as most reviews say that the card pretty much maxes out at 900 with no extra power. idk if this is AMD spin or what.

3) can the card be flashed with any other bios? should i do this? are there any other tricks i can pull off here? i'v never actually overvolted anything so i'm pretty noob here.

lastly, anyone else have this, and what results did you get? all info much, much appreciated as always.

:wub:

I don't know much, so i'll simply go with what makes sense. You could overvolt through the PCI-E slot but I beg you to take it very slow and do plenty of research because not only can it damage the gpu, but it could backfire onto the motherboard.

well .. it doesn't overvolt. and that's that :/

still works decently for £75
