You did! I am using the default custom fan curve (Seems to just keep up with the temp? 50c = 50%). Seems to get to about 70c full load in benchmarks like Valley and Heaven. What would 1.212v be in Precision X? Max? I need to read up on this because I have no idea what im doing when it comes to voltages.

Hey guys, I just got an EVGA reference 780 and put an EK waterblock on it. I wanted to get your opinion on how my OC is going. I followed the guides for setting up AB, doing the LLC mod, and reflashing the BIOS. My problem is that I think my card is "too good" and wanted to get a second opinion on the set up.

I started at +300 core (around 1200mhz) and slowly went up 50mhz while doing Firestrike Extreme between each to test for rough stability. Well, I'm at +500 core and still no artifacts at 1.325V and a temp at 41C. Firestrike is showing my core is ~1400mhz, but AB is show it fluctuates between 1360-1393mhz. I noticed my power limit is hitting 123%, but the slider only lets me go to 115% but I prioritized temp, so maybe that doesn't matter. Does this seem about right? Should I keep upping the core? Hitting close to 1400mhz seems kind of extreme, but its not crashing or artifacting yet.

Here is a screen shot, I have my 4820k at stock speeds right now:

AB and Precision X allow voltage control up to 1.212v. If you want to go higher than that you need to get the Classified Voltage Tuner tool.

What are you doing with AB and PX?
Classifieds have the CHIL CH8318 voltage controller! You have the Classified voltage control tool wrote for that voltage controller: Classified_v2.0.4.3.zip 203k .zip file

GPU (NVVDD) OverVoltage
Memory (FBVDD/Q) OverVoltage
PEXVDD PLL Voltage Measurement

So:

NVDD is voltage for GPU

FBVDD is Memory voltage

PEXVDD is PCIExpress Voltage

I used Precision X to max out the voltage (+63mv) then bumped the core to boost it to 1306 (+140 I believe) and seemed to bring the voltage to 1200, in precision X. Was running perfectly fine. Then as I was streaming Planetside 2 while in a tank, I got blown up. As soon as the explosion occurred on my screen, my PC shut down. I was worried, so I turned over the overvoltage and brought the core down to +100. No issues after that...

Any reason as to why this would happen? What can I do to prevent that in the future if I want to bring it back to that OC?

Latest Nvidia driver has been having issues with PS2 causing black screens etc. even on stock clocks AFAIK. It may have been that.

Well since you know +100 is stable and +140 isn't, try and inch up in increments of 5 to see what the best OC you can get off of stock voltage is. If you're still yearning for more after that, give a BIOS flash a shot.

Set the voltage with the tool i provided, it was written by EVGA for your card specifically!
Set the voltage to 1,212V and you HAVE 1,212V, you have voltage up to 1,35V! Only use AB or PX to set clocks!
Sorry but you are just wasting your time with AB or PX in the voltage department!

Just my 2 cents!

115 or 120 is stable on stock voltage. I was playing Planetside all night without any issues with the OC set to that on stock. The other night was when I set the voltage on PX and then brought the core to bring it to boost at 1306. It seemed stable for awhile, no issues at all. It wasn't until that huge explosion on my screen that caused the PC to restart. Hoping my PSU isn't the issue there.

I will use that tool later, for sure. When I looked at it, even though there are only what, 4 sliders, It seemed more overwhelming than just turning overvoltage to on and pumping it to max on PX, lol. I have never messed with voltages before.. whole new territory for me. My motherboard auto adjusts voltages when overclocking the CPU, so that was as easy as going into bios and setting it.
