On Afterburner software though it recorded a max V of 1.304
So yea, no idea what that means :/. Does it mean my Voltage is software locked at the default 1.1750V?! Coz if it is that would suck nut.

Doesn't sound right, does the meter hold the max recorded? You could try watching it to see the changes as well.

& OC that card. wink.gif

Are you sure you have it plugged into the right test port on the card?

Looks like you connected it to the wrong one. The core is the closest one the pcie slot I believe.

^^^^

Looks like PLL voltage.

Yes, the VGPU is the closest to the PCIE slot, than goes the VMEM and VPLL /V AUX / , looks the same to me...
post #2347 of 7827
Hahahahaha, lol. I'm just a noob. It was not in the correct pin out ;/. In my defence though I used this as a guiding point on which pin out was the Vgpu. Seems they got it backwards. Afterwards I took out my card from my case and saw that underneath the pin outs they had the icons for what they were supposed to measure. Did the measurements and my card at full Voltage tilt was getting 1.355V in heaven. So seems I got some headroom for voltage tongue.gif. Thanks guys.

Hey ftw, I am in the process of doing just that smile.gif Want to see what i can do with this card tongue.gif. Oh and I think i saw your name on the MSI lords of overclocking list? Are you going to Taiwan? If you are Well done bud, if not still a sick single card bench you have there smile.gif See my fellow South African drewez and vivi made it tops smile.gif

Also another question: it seems the volts are a bit high on my card when it is running at full tilt on the normal bios : Even though they say max locked volts for the lightning is 1.1750V when i run heaven with a MM attached it records the Volts hitting 1.204~1.206. This is with core V and power limit set to normal on AB.

That's correct. Even the references, also "locked to 1.175v", measure around 1.2v on a DMM.

No Taiwan for me this year. I was the first runner up in the americas part of MOA qualifications, & now 3rd runner up in single gpu for LOC. I'll have to work harder at it next year.
As dph314 said, that is normal for the regular stock bios, with any card the true voltage is rarely the same as software reported voltage.
