Over Volting, 38mV safe for GTX 780 ?

Yes.

Strictly speaking you can't over volt a 780. The +38mv you have available will still be inside nvidias spec range.
 
Have overclocked my 780 to the max, the extra 38mv made no difference at all to mine, 1189 core with or without overvolt.

I'd be interested to know if yours is any better.

Well without the over volt I can only get to around your number but with over volting I have it set 1202/3202 all stable and temps are great :)
 
A few people have said that the voltage can hinder your performance as the extra heat can raise temps which leads to throttling. It seems with nvidia's new overclocking keeping temps under 70oc is a good idea for maximum performance.
 
The memory clock does not throttle so get that as high as possible. My core clock will only go to around 1176mhz, but i have the memory at 3260mhz :)

Great cards!
 
If its anything like the memory on the Titan you should be able to get a lot more out of it.

I can ramp mine up to around 3500-3600 depending on the situation & the core frequency.

Damn I wish I could get that high :(

What clocks are you getting?

I've got two GTX 780s coming tomorrow - I'm hoping to run them both at 1100Mhz or thereabouts. Obviously the temperature of the top card is going to be a lot higher, so I'll test them individually first, and pick the coolest-running of the two to sit at the top. 1100 Mhz might still be a bit of a tough ask for SLI, but I have a HAF-X with the "GPU funnel" to direct air straight to the GPU intake, so who knows. Fingers crossed.

The HAF X VGA cooler didn't fit with my 7950s so bear in mind! :)

It did with my 680s though.

Hmm... I hadn't considered that.

Checking now though, it seems that the GTX780s are 10.5" in length - the same as the GTX480 that's in there now. So it should be okay...
