GTX 680 OC - Result-Thread --- Post your results here

[cowie]

You think 250w is alot ...they turn into black holes with 1.40v+ you would not even believe me lol

[CryptiK]

I'd believe it, they suck huge amounts of power and higher voltage/clocks. It's over 270w at 1359 MHz / +900 mem and 1.33v

My aquacomputer MSi GTX680 lightning block arrived today, thanks Gary @ Sidewinder for shipping out the item in the middle of a blizzard


It really is a work of art. I'll let the pictures do the talking.









And this one just for fun after I mounted the card in the upper slot for the first time




And of course results (after full round of 1000 tkt BF3) @ 1293c/8002m






Full load ends up being ~40-42*C core, 35-37*C mem, 45-47*C VRM

Shaved about 30*C off each component and best of all as you can see in the shot above, mem is now fully stable at +1000 MHz (on stock mem voltage) giving 4001 Mhz or 8002 MHz effective and 256 GB/s bandwidth.

Yes, I have two of those blocks as well.

They are the shiz for us water OC'ers.

[NapalmV5]

what you guys getting in hitman absolution ?

[CryptiK]

No idea man plus I only have one card.

Playing BF3 @ 1398 MHz / +1000 mem @ +93mv




it locked eventually but it's 30*C in my study today, was rocking it for awhile at 1372 MHz after that. Not too bad.

[NapalmV5]

why didnt you get 2 cards ? that would be equivalent to 3x 580

even 1 card would do.. i multiply it by 2 for a 2x 680 performance

anyways.. at first fps seemed kinda low and i had no idea what fps im supposed to get what fps other gpus are at but after looking around still 2x 680 equivalent to 3x 580

[CryptiK]

I had 2 cards but just dont need them for what I play with my 2560x1600 res, and I know I'm going to get a 700 series when they drop so figured I'd minimize the expenditure this late in the 600 series. The 680's seem much better than the 580's but I'm not sure it's exactly double.

[cowie]

Really need 1.40+ to run over 1400+ stable i tested 4 cards, even the card that does 135o out of the box needs it,if you ask me the 1.30v-1.39v range has very little returns but thats just me

Very nice block its looking good on the clocks too.

When it comes to bf3 1449 is ok all day 1.43v with a h70 for cooling and some heatsinks and fan over vrm it never gets much over 50c in a 67f room.

Yeah it was close to 1398 BF3 stable at 1.34 -1.35v, haven't pushed over that. I'm tempted to hard mod it, easy mod with a 500 or even 100 Ohm VR. In LN2 BIOS OCP is insane so no worries there (you'd probably smoke the card before you tripped OCP), even running 1.35v in normal BIOS is no problem.

You have a card that does 1350 on stock vgpu? Damn.

How do these GPU's handle the high voltage? 28nm is hella small, I'm worried about degradation. When you say the 1.30-1.39v range has little returns - MHz with added voltage scaling should be close to linear for a short period then begin to plateau. Have you made a graph? I would have expected the MHz/voltage ratio to fall as voltage increases not the other way around.

[cowie]

Yes it does heaven stock cooling 1340 np,thats if its not too hot in the house.
This ss is in early summer time no ac yet so it did clock down abit to 1340.
Stock bios no mods at all right out da box


Ok so from what you have at stock 1.21v? 1270ish now 1.375v and 1370 with better cooling? IDK thats ok but 1.40- 1.47 it goes 1400- 1520(with water cooling + cool air + modded bios)
1515 1.47 with cold air




It just did not respond much for me between 1.30 - 1.39v is what i meant
sorry i have no graphs was sorta getting away from the 680 modding then some started to join in so i got intrested again.

Not sure how tough these buggers are but i have not killed one and over 30 times sub zero with up to 1.59v,alot of 1.40v+ time too... still the same

[CryptiK]

Damn thats a nice card man. I'm all paranoid running 1.24v on water lol @ 1293 (mines not as good as your core) but my mem does +1000 on stock volts which gives me some nice bandwidth

[NoGuru]

No spreed sheet on the first post? Not going to be a good thread for comparing Data.

[CryptiK]

I think everyones got a pretty good handle on what the 680s can do by now.

[CryptiK]

memory bandwidth vs core freq brief comparison

1280c/8000 Mem (+1000)




1306c/7000 Mem (+500)




Seems the extra 500Mhz (1GHz effective) mem contributes about the same in 3DM11 as an extra 26 MHz core freq.

[cowie]

Yeah i'v deducted early in my testing about the same thing,i'v had up to 1.87ddrv was ok to 18o0 only so i dont bother anymore.
Out of the fm benches high ram speed is liked by 3dvantage the most others its so so.

[CryptiK]

Had some driver issues with 310.90 like everyone else and rolled back to 310.70 but still had some issues here and there.

Anyway.......... installed 313.XX betas and ran heaven again. Ran really smooth. They're great in BF3 too, much better FPS and card utilization was up around 97-98% for both which was a marked improvement.

Heaven @ 1080P | SLI GTX680 | 1267core @ stock vgpu | 7408 MHz @ stock vmem | 990x @ 4GHz

[Ivanlabrie]

I hated 310.90...had to lower my oc and didn't work smoothly with all titles I played.
Sold my 670 now though, and my cpu died. But I did reccomend the buyer to get the new beta. Hope they play nicely for him.

I know it's the gtx680 OC thread, but I'm going to post anyways!

^one AX650?

if so that is awesome.

[CryptiK]

Heh and I thought I was going well with SLI 680's on an 850w

Thanks guys.

And yes, that is all done with my trusty AX650!

Here's a current pic of my rig:

Very nice computer. AX650W COOL

[CryptiK]

One of the things I really like about the 600 series is their power consumption. For 24/7 I run both mine at 1202/7400 @ stock vgpu and they use well under their 225w TDP. Both cards and the 990x run comfortably on the 850w PSU, although on a hot day gaming it does start to blow some hot air from the unit. 650 is probably pushing it up into high 80% or low 90% duty keeping up with the GTX690 + 3970X. Only thing that will probably make me change is lack of proper cables, I need 4 x 8-pin PCI-E but my PSU only has 2 + 2 x 6-pin so I have to use ugly adapters on them. Considering cutting and soldering them though, it's a lot to spend on a new PSU when my 'works' but just has one aspect I'm not happy with aesthetically.

Watch when Titan is released, everyone who buys 2+ of them will have to upgrade to 1200w+ PSU's

[flesheatinvirus]

I totally agree, I love my 680 on water compared to for example my 580 Classi which was simply huge.
