post #10831 of 21379
Alright so after some tweaking last night, looks like I got it to +130 on the core( 1240) and +600 on the memory (1802) running the skyn3t rev 4 bios at 1.212 mV and a 100% power target running 3dmark performance bench. I've noticed that increasing the power target past 100 doesn't seem to run stable, and anything over on the core causes some screen tearing. This is Using Precision-X. my goal is to get this monster up at 1300 core and 1802 memory Stable, but we'll see what happens smile.gif

The power target only comes into play if the card is hitting that wall. If you're at 100% and going higher is changing the behavior of the card, then you're most likely throttling based on the power target.

OC the core and memory separately. Start with the core and then after you're done move onto the memory.

Keep an eye on both core and VRM temps. HWInfo has VRM temps. You can sometimes see VRM temps on GPU-Z as well. If you're going to use HWInfo and GPU-Z I would recommend not using the 335 drivers. For some reason the 335 drivers in conjunction with something else (no one knows for sure as far as I can tell) can cause the 780 Classy to set itself to 1.5v on the core. So watch out for that.

I think on the first page they list the different modded bios for the classy versions, mines disabled on my 780 classy using the rev 4 bios, not sure on the ti though
post #10835 of 21379
yeah that's what I did, 130 core seemed to be the most stable at 1212 mV so far, and them mem peaked out around 600(went for 650 with a crash) , buts that's also leaving power target at 100%( which in the rev 4 bios states 100%=600watts! )

OK I didn't look at what the PT was set to at 100% on Rev.4. Your memory is beast. What's your core temp at 1.212v 1,240MHz?

Anyway to disable the LEDs on the 780 Ti Classy?

There is no way to disable it. Those LEDs are actually the health of the VRMs. They have to be on. Bright white means they are healthy.

Check out EVGA's forum:

Also, the LEDs are meant for Ln2 cooling, according to K|ngp|n. The reason is when the nitrogen is giving off smoke, you need to be able to see if they are lit up. If a light goes out, there is a problem. I understand that may be frustrating, but you did buy a card that is specifically geared toward people that want to use Ln2 or Dry Ice cooling.

They have also stated many many times, over and over, that they will not make a way to turn them off.

When I ran 3dmark a few different times, it sat around 60-65C load with the custom fan profile on rev 4 bios, smile.gif , that's why I'm figuring it could be something else peaking the core if temps are in good ranges. Might need to try that LLC disable mod I've been hearing about

You don't need an LLC hack for the 780 Classy. The LLC hack is for cards that use the NCP4206 voltage controller, the Classified uses the CHiL 8318 voltage controller.

In addition the Classy doesn't suffer from Vdroop. Lots of people have measured core voltage with a DMM and found that the Classy actually will overshoot set voltage a bit under load, but it's very close. When you set voltage with AB / PX / Classy Voltage Tuner tool you can be fairly confident that what you're setting is close to the actual voltage.
