Not had a decent gpu for a few months and its amazing how quickly you forget stuff, so with that in mind what is the current thinking on the best tools to use when overclocking this card?

Normally I have used afterburner in the past but look forward to your input :)
 
I hear that. I am tempted to put my waterblock on my Titan but work at 2pm and I wouldn't want to be rushing and was hoping to hold off till I get my other Titan back, so I can put them both on water at once.

Anyways, have a read here Tony and see what these guys think of overclocking on the 780's. Also Geeman is quite up on them, so hopefully he will chip in with a few bits and bobs.

Some good guys there :)
 
Nay lad don't rush it wait till new Titan arrives, sorry to see you had a spot of bad luck with it :(

Aye will do some reading up and ask a few folks for input. Just done a run with gpu at stock and cpu 4820k not overclocked and got 1452 interesting that although it showed gpu 99% useage power on afterburner never went above 72% hmmmm
 
That was Heaven?

Not sure what the TDP is on the Classy but power usage will be lower while everything is stock but when you start to push it hard, the power should fly up. How much do you have on the stock power limit?
 
When you start pushing the card, you will start to see the power usage rising. I assume it has 2x8 pin connectors? and this will give a total of 375W's of power, so while it is only showing 72% power usage, it is only using 270w, so you still have 105w in the design specs available for overclocking.

In short, that reading is perfectly normal :)
 
Worked it up in small bumps of 10/15 to +125 on the core gives 1267 and Heaven 1553 does not matter what I do after that Heaven simply will not run, the card does not artefact or anything Heaven just crashes at anything over +125.
Had a look around and a few people recommend this skynet bios, am not against it just a wee bit disappointed can only clock the card to 1267, I know asic is not the be all and end all but I thought 82.3% would bag me something pretty good.
Will keep trying but it looks like an alternative bios is my only option to get anything higher ..... sigh :confused:
 
1267 isn't bad and I am assuming that is on stock volts? (1.212V) Nvidia seriously annoy me when it comes to overclocking and try and take the fun away but thanks to people like Skyn3t, we get the fun back.

1.3V will net you 1350Mhz+ hopefully and 1.4V over 1400Mhz.

Make sure you save a copy of your original BIOS just in case you have issues.
 
Yup stock volts, am in the mood to experiment so have backed the bios up in 3 different places :D

You think I should go straight in for the kill with skynet rev3?

Does Matt love AMD? :p

Of course and just make sure you don't go mad. I would stick to 1.3V for now and see how you get on. The HydroCopper cooler isn't the best from my reading about but it does have VRM cooling, so I don't see a problem.

Patience grasshopper! You're running the card to lean if it's big clocks you're chasing. You'll need more voltage applying. Get the Skynet bios as Greg advised and down load the Classified Voltage tool.
 
Ignore asic too, both my phantoms do 1306 @ 1.21v both sub 70% on air (for now).

+1 for skynet and classy tool, which should give you an easy 1.35v to play with.

I must stress to make sure your psu is up to the job, some of the skynet bios' can do in excess of 450w!
 
1267 is ok for stock volts. My sc get 1240 before hitting a wall. As Greg says with access to 1.3-4 you'll see over 1300 with ease.

Wouldn't pay too much attention to the asic. My worst clocker is 82% and my best one is 74%.
 
Cheers for the input chaps much appreciated :)

Downloaded bios and nv flash etc just having a brew before I pull the trigger, does not help getting the hang of nvflash when your on day 16 of no smoking :(
