It's only 30 mhz less than my previous OC, with 1.212v. And, what I didn't see before, I saw artifacts at 1280, so I backed down. Previously the games/benches would just crash, never saw any artifacts. So, my conclusion is, that my videocard in those cases had reached the maximum amount of wattage drawn from the PSU? I have 2x 8pins, which theoretically means 375 watts. Is that possible? Because at higher voltages the card would simply crash, before giving me the slightest artifacts. That felt strange to me.

Try Precision X, afterburner didn't quite work for me as well..

Your card was crashing because it wasnt having enough amperage from the PSU but because it needed more voltage!

The current I in amps (A) is equal to the power P in watts (W), divided by the voltage V in volts (V):
I(A) = P(W) / V(V)

<=> W = A x V

Meaning you need more voltage to get more wattage!

Now a little electrical basics:

a) Voltage:

Voltage, measured in Volts, is the electrical potential for a circuit to do work. If a circuit has voltage, it has electrons ready to flow.

b) Current:

Current measured in Amps or Amperage, is the flow of electric charge. When electrons flow, the movement of those electrons is measured in amperage.

c). Wattage:

Wattage, measured in Watts, is the rate at which energy is transferred by an electrical circuit. Typically wattage is measured by multiplying Amperage by Voltage.

It's working with precision X (1.212v) but I want to use afterburner to be able to reach 1.24 with llc hack.....
post #6748 of 16495
Flashed the skyn3t BIOS on my ref 780Ti this week, thanks a million for the work you guys have done. thumb.gif

I forced a 1.212V through KBT at P00, since it didn't seem to change when I tried upping it in EVGA Precision X, which works well for me as I'm planning to flash my finalized OC on the card when I've tested it thoroughly. It now shows 1.212V in GPU-Z when loaded.

I can loop Heaven for hours without any issues at 1250MHz, temp is under 70%@100% fan. I haven't work in little steps (will do more fine tuning when I get home next week), but when I hit 1300MHz it will reboot the rig after a few minutes (less than ten), temps on core are still at low 70's, no artefacts can be seen, memory is at stock. Can this be because the VRM's get overheated with the ref cooler, meaning if I get a FC water block I will be able to go higher than 1250 (looking at WB anyway, but might not aim for a new one because of the voltage limit)? Or is it simply a OC limit?

Will add a submission to this club when I get a chance.

What do I need to do to reverse the issue? Just delete the lines on the profile, or more?

The LLC doesn't work on the Ti. Afterburner doesn't support the Ti at all.

So right now the max voltage I can get on my ref Ti flashed with skynets bios is 1.212 or 1.24 ??
