yeah i know, but I still don't want to be all talk, even if just for a while

you sometimes meet that one guy who talks and talks and thinks hes awesome but never backs it. I don't want to be that guy lol

1.5 is crazy.. dare i say.. overkill for those clocks though i think Wump! If you really cant run stable lower GPUv than that....you really should treat yourself to a new GPU.. shouldnt need more than 1.35v for 800mhz clocks on any G92 core..and if you cant run the speed..it aint voltage..its temps..

*at least from my experience.. I have over 24x G92 mods under meh belt.

well honestly 41C or lower in benches is pretty damn good temps

its mainly the core that isnt willing to go higher. the shader was happy at 2260 or something mhz while the core will only do 907....

BTW it did 790/1980/1250 on stock volts & cooler so it should clock ok.

With temps like that..and an uncooperative core..sounds like you may need some Capacitors!! Shaders are what will max out with your temps..core is what needs the voltage though.. Should take some measurements off your GPU on the input phase and output phases to see if you can spot the achillies heel. Just watch voltage under load to see if inputs are drooping below ~11.83v ..or if output voltages are drooping too much from set GPUv under load.

*caps on my GS's brought my core speed up another 45mhz on water.

core volts actually go UP under load! idles 1.48v, loads 1.52v

weird stuff coming from this thing....
although I wouldnt mind another 45mhz on the core
only problem is I gotta order some caps!

EDIT: I assume I could get regular capcitors, and not have to get more tantalum or solid state ones.....

I would reccomend to add some low-ESR (solid) caps in parallel to existing ceramic caps on the front and/or back of the card, or to some empty cap pads.

Is that card identically to your one?

Edit: are you using a GPU only or fullcover water cooling block? If it's fullcover there's probably no space left for adding input caps on the front.

yep thats the card!
and luckily its a GPU only block.

I've marked some spots on the pics where you could add GPU output caps(f.e. 2.5V / 820µF). The blue spots on the front might be the corresponding input caps.

Anyway, check all of them for voltages and polarity first.
