GTX 780 Owners Club

I likewise considered a 970 or two (and still do from time to time) but my 780 is underwater and thus it would be a bit of a hassle to "upgrade"

Also I have sworn off upgrading until GTA V, I want to know whether I can run it enjoyably before deciding.
 
Been getting the upgrade itch but just can't justify it personally. Only play at 1440p but still it copes pretty admirably to be fair. Really fancied a pair reference (Titan style cooler) 970's not at the price OcUK are doing theirs. Will probably hold fire to see what AMD have to offer or the 980Ti.

I found overclocking on the stock bios to be stupid as clocks wouldn't stick as power and temperature limits kick in and things changed.

Flashed Skyn3t's bios and eveything became super easy. Clocks stayed constant and you aren't limited by the 106% power limit.

Finally be careful with using heaven as a stress test. I have had 2 780s, a lightning that wouldn't do 1200Mhz n any game yet was fine at 1250Mhz in heaven and my current reference that will happily run at 1280Mhz in heaven but games will crash above 1240mhz (all using 1.212v).

Thanks for the heads-up. It's what I always used to use, but the last card I clocked with it as a test was a 480 not too long after they came out, so I'm a bit behind the times now.

I imagine 3D Mark (if there's still a free version?) is still a decent stress test?
 
Reached +238 on the core and +500 mem for my overclocks, which seems really good. Gives 1228MHz max core boost, and 3504MHz memory.

I see no artifacts or anything, which makes me think this isn't the maximum for the card, but I notice that at stock memory I can't increase the core past +240, but only because the maximum boost actually goes down after that. It goes down to 1215MHz at +245, and back to stock boost (993MHz) at +250. The volts drop from 1.162 back to 1.150 as well, which I guess is connected. If I clock the memory up, +240 drops to 1215 too, but +238 sticks at the max boost of 1228MHz.

I don't know why this is, but I guess it's something to do with the power draw exceeding the maximum (temps stay well below the 78-80C throttling point, maxing out at 73C at 85% fan).

Anyway, I think this is quite enough. It's a really pleasing overclock and probably already more than I need for 1080p, but this variable boost feature has been tricky to manage. Feels like juggling one ball too many at times. Guess this is what Disco_P was referring to?

I have never used 3D mark for anything really.

I always rely on games for testing. BF3 spawn screen is my go to as it stress the CPU really hard at the same time. Never had a clock speed pass 12+ hours of BF3 and fail elsewhere.

Guess I need to install some games then! I've tested these clocks with multiple runs of Heaven, Valley and Firestrike, but I don't have any demanding 3D games installed at the moment. Will be grabbing Crysis 3 soon I think to give it a good workout. :)

Yeah all that juggling with GPU boost 2.0 made overclocking my 780 a nightmare. Hence I flashed the bios and everything was hunky dory.

Looking through the list of modded B1 Bioses the most appropriate one for you would be the EVGA SC one. That card uses the same PCB as yours so I would assume it will work just fine. It'll set the base clock to 1006Mhz which it won't boost from (however it will downclock when not under load) so if you want 1228Mhz just put +222 and it will run at that speed.

BACK UP YOUR CURRENT BIOS FIRST
GPU-Z can do this for you.

Use Ez3flash for super easy flashing. And if it all goes bawls up you can reflash the original bios by running your monitor off another graphics card or your GPU's integrated graphics chip.

I though about a pair of 970's, mainly due to running cooler. But decided not to. Would have been a sidegrade and id need two reference models anyway which are just out now from ocuk.

I did pull the trigger while my missus wned back home to finland:eek:

But thankfully when paying cc it was declined:D

Was palying COD.AW in drs 4k and as getting above 70fps (need to load up again as I'm sure it was 90fps)

Aka the missus cancelled the credit card as she had an inkling you were gonna go on a spending spree, womens intuition and all that.:D

Tbh ive still thought about changing a few times, but slap myself back to reality.:)

Cheers. I'll check that out if I decide to push it any further. I'm happy enough with these settings for now. Getting an extra 20-25% performance in benchmarks, so I consider that a very pleasing result.

I'm sure it could do more though, and one day I'll probably decide to go for it. Actually, think I'll download the BIOS now anyway and keep for a day I find too much time on my hands...

If it goes correctly (which is should) a bios flash literally takes 5 seconds. In fact I could flash my bios to stock and back to my current one quicker than I could write this comment.

Wow, that's quick. Mind you, for me there'd be a lot of reading up on it, making sure I was doing it right, double-checking.

No chance of bricking the card if something goes wrong? (I still remember bricking the motherboard of the first PC I ever built with a failed BIOS flash...)
 
I found with my 780 the power target was more of a limit than the volts for 24/7 use ,, a skynet bios soon sorted that and they are very easy to flash.
Some versions of EVGA precison(not sure if the latest does or doesnt) also let you put 1.3v thru your card for that benchmark you want a little more out of :)
 
Wondering if I should buy a used GTX 780 somewhere that I can SLI, Currently have a Gigabyte GTX 780 windforce OC Rev2 version however I game at 1080p but I have a 144hz monitor, Much prefer frame rate over resolution so I find myself turning all the settings down to low in-game for higher FPS, Would buying a used 780 be a good idea now?

I would like much higher FPS and higher settings once GTA V lands on PC, Along with the Star Wars Battlefront 3 game which is out sometime in 2015.

Once you see the refresh rate you never go back!

Its a shame you haven't got enough posts to be on the MM. My classy will be up there soon....
 
If you do go for another 780, id strongly advise going with a reference design. If you bung two non refs together youll run into heat issues on the top card. That aside 780 sli is still pretty powerful. Though with newer games it remains to be seen if 3gb of vram will be enough.

Go for it if you can pick one up cheap enough. You'll be set for a good while to come.
