Now that i took care of the warnings for your sake and mine, lets go for it! tongue.gif

Between the front set of DIMM slots and the onboard buttons you have a series of four, three pin headers. These are all for the VGA Hotwire,(they come in the bundle) the red sets are for the VGA Overvolt, and the black are for the VGA Sensors.

The seven yellow small boxes are voltage measuring points!

Very cool!
Thank you!
So the black ones plug into the board, where do the red ones plug into, just a little confused? The black ones get soldered to the sensor points on the GPU(the open rings)? Yeah not sure on how easy it will be to get water blocks, just picked up a pump on Flee bay. The blocks have to be for the DCII right as it is a none reference card. I found very few looking at the usual water cooling places.

Again Thanks!

Does anyone know what kind of temperatures the VRMs on a reference 780 will run at? I'd just like to know if I have enough temperature headroom to run 1.2V.

In the motherboard three pin headers, red cables go into the red headers and the black into the black headers, the other side of the cables are the ones to solder into the card, reds for voltage and blacks for sensors!

Worse case scenario 50C above core temp! Try to keep your card below 75C core temp! Most VRM components are designed to run at 85C max, when your core is at 80/90C those parts are overheated already!

Hm, I was just wondering because blowers seem to have the best VRM temperatures, when I had a reference R9 290, the VRMs ran much cooler than the core and peaked at around 70C.

Stock coolers (1 fan Blowers) have an VRM cooler plate that helps cool down VRM modules more effectively, other cooling solutions that dont have that plate will have higher VRM temperatures!

If DDU does not solve the issue, re-install OS and install the games and nvidia drivers first! Run the games to be sure its not some update (KB2670838, W7 only, pre-requisite for IE10 interferes with DX10 in a lot of game engines)
Then install the other software you have so you can narrow down the possible problem origin!

I did the driver clean and that didn't work...however, I got suspicious since I still hadn't really installed much on this new installation outside of games. Wait for it....


FRAPS.


Even BF4 is working fine now. I had it starting with windows to keep an eye on my FPS for games. At first I was thinking it was EVGA PrecX, and then I though; why not FRAPS, I've read of a couple people having trouble with it. I almost went into clean installation mode again. Needless to say, FRAPS will be uninstalled.

What CPU is a minimum for Gtx 780 to play games without bottleneck?
E3-1230v3 or i5 4440?
