780 overclock, reference or not

[florps]

Hey i was wondering if i could overclock a reference 780 as far as something like 780 acx or dcii.

Thanks

They make completely different PCBs, power regulation and coolers, which help the overclocking compared to the reference. But the most important thing is heat, if you can keep the heat away, then you could get very close.

Hypothetically, you could. I have no experience with reference 780s, for the record, but I've got a reference PNY 760 (worst mistake ever) and, although I don't overclock it because I want to sell it soon and want to be able to say I haven't overclocked it, I have a lot of thermal room. However, I only get this thermal room if I blast the fan at 100%, which I don't mind since my gaming headphones are sound isolating.
My point is that, if you don't mind manually turning the fan up higher than speed%:temperature, then yes, you can achieve higher than reference clocks. My gpu is about 10-14C lower than it was at normal fan speeds.

Just an experience.. Got a gigabyte 780 oc rev 2.0 the other day. The card comes with a new type of windforce/triangle cooler. (not just 3 fan windforce like my old 570's) and the card also has 10 phase power delivery (8+2)
I've hit the max without voltage adjustment past 1.162. Core: 1162 Memory:61xx
90% fan speed keeps it at 52 degrees

I'm pretty sure the ACX uses same PCB and power delivery. *i got it anyways since EVGA has great support*. The overclock will be fine on vanilla. There's plenty of thermal headroom, unlike the r290s.

My reference MSI 780 has plenety of thermal headroom, thanks to my custom fan curve, but it's an overclocking dud.

1080-ish max sustained boost is all I can get stable at stock voltage.

It's a beast at stock clocks, so any improvement is icing on the cake, but I have been lucky with two previous GPU's, as well as two different CPU's. I think I just got spoiled and expected to get good silicon every time.

I was also only able to get memory to +150.
