GTX 780 Owners Club

[eyetrip]

Oh, there's a club for me to join

Yawbster, Precision is pretty decent. I was using it for my 670 windforce + 670 FTW SLI setup, as it was better for multiple card ocing than Afterburner.

Swapped over to Afterburner for my lightning 780 for voltage control, though needn't have bothered, as more juice doesn't really get me much higher clocks.

Found EVGA tool better than the MSI one. Used the MSI with the GTX570s and the 7950s. However tried the Precision with the 780 and haven't looked back.



As for voltage, if you do not use modified BIOS, all but the EVGA Classified, is capped @ 1.2v, no matter how much power over you put on them.

For example mine, at 106% + 38mv is the max power that can consume (1.2v). Even if I put it wall way to +50mv, does nothing.

And don't see the problem imho. This was the very first pre-overclocked card ever bought, and while I can clock it more, I haven't found the need other than when I am benching.
(cpu on the other hand is living at 5000 all the time).

Runs quiet and cool. (paired with a 650ti doing physx).

If I had watercooling, then probably I could have put a modified bios to run it overclocked 24/7.

Got mine installed today. So far just running it at stock, (1097mhz boost). Maxing at 72c in games and heaven on auto fan setting. Need to read up on clocking it as it seems slightly different than my 670's, temp target setting im not sure about tbh. Max power target reads as 105%, gigabyte wf model.

I've got a pair of MSI 780's recently which are happily running at 1100 Core and 3500 mem.

Want maxwell to come now so can get some cheap deals on another 780.

Wouldn't mind another lightning, but think I'd have to get that soon as think they will disappear

Though I know it's generally not a good idea having two such cooler fitted cards dumping heat in...

Samsung ram on mine but it doesnt seem to clock well. Managed +120 on core, (1215mhz).

What did you manage on the memory?

 

[setter]

+100 is the most ive passed any bench on so far. Initially tried +400 but it artifacted in heaven and reset the clocks.

 

[Stanners]

Is there a tool for finding out what memory is on your 780?

 

[setter]

Nvidia inspector, install it and hover your mouse cursor over the ram box, it will pop up showing what ram it is.

Cheers.

Hynix RAM on my 780 GHZ WF3 :S how well it clocks seems to depend on the core speed for some reason - stable at upto +500 with the core untouched but even one speed bin up on the core I can't get the memory above about +350.

If could be a PSU issue ! I've seen this before.
What kind of amps does your power supply deliver on the +12v rail(s) ?

Seems you are right. Is down to PSU. Currently I have a Corsair 750W (80 Gold) dual rail one. (3y old).

Why I say that.

By raising the CPU overclocking to 5Ghz, the GPU is struggling to get now to 1271. Had to unplug the GTX650ti (PhysX card), and made it work again to 1271.

However couldn't get more than 3007 on Valley. Lowered the overclock of the 4820K to 4800 @ 1.35v (At 5Ghz needs 1.4v). The 780 went back again to 3130 score @ 1271Mhz. Raise the CPU overclock, the bench went down to 3000-3007. (did this 4 times to make sure).


According to the GPUZ log, it gets power limitations more often when the CPU is at 1.4v than at the 1.35v during the benchmark.

Put the CPU to stock speeds, and the 780 went to 1300mhz without complain. (didn't dare to push it more).

Run valley, and while the score was lower compared the previous settings, there was no voltage limitation shown on the GPUZ.

So for sure I need a better power supply after Xmas, which means £200 for this seems a good investment

(FYI 24/7 I run the card at factory overclock, only the CPU I have pushed at 5Ghz).

Waiting for my 4th GTX 780 to arrive Palit GTX 780 Super Jetstream 980MHz core (1033MHz Boost) & 6.2GHz ram.
It will be placed in the 2nd system. I'm looking forward to see what this card can do

I have one of those. One MSI Gaming and one Palit Super Jetstream.

The Palit is by far the better performer, in both clocking + cooler. Haven't tried pushing the memory too much though as it has the Elpida chips.

Hehe I have a MSI GTX 780 Gaming OC 3GB too - that's the one I have in 3-way SLi with my 2x reference MSI GTX 780 3GB cards in my main rig.

The Palit GTX 780 Super Jetstream TPU says has Samsung Ram ? (not that it matters to me).

The review model might have had Samsung, but it doesn't mean all do

Ahh okay

Have to say most of my best OCing cards have actually been the POV, sparkle, palit, etc. ones - often they have low ASIC/high voltage out the box but get them nicely cooled and they seem to clock like crazy.

74.8 on my MSI, 80.0 on my Palit.
