As I do not see any threads for GTX680 overclocking, I thought I would take it upon myself to make one to generate some conversation for those of you toying with this new "offset" overclocking since it utilized Dynamic boost to OC the GPU depending on power usage.

I an using an ASUS GTX680 card, but using the beta version of the MSI Afterburner utility. ASUS has their GPU Tweak utility, which I found to be nice, except that it is lacking the OSD that displays my FPS, temps, or whatever else I want in game. Afterburner has this, I like this, so I am using this.

I am currently running a GPU offset of +100 which gives me a base clock of 1106MHZ and will boost to about 1227MHZ at peak. I gave it a +400MHz offset to the Memory which with DDR gives me an effective clock of 6808MHz.

I also had to change the power limit in Afterburner to 120% to keep the boost form bouncing around so much. And I also changed the fan profile to be slightly more aggressive.

Here are a few articles that I found helpful so far.
http://www.guru3d.com/article/geforce-gtx-680-overclock...
http://www.tweaktown.com/articles/4623/nvidia_geforce_g...


I was curious what the other GTX680 owners were finding with their ventures.

More about : gtx680 overclocking

I have the MSI gtx680

I set the power limit to 132%
Core offset to +150
Mem offset to +500

I haven't played around with it too much yet but I have had no problems with these values. I will probably work on it this weekend just to see what I can get this thing up to, not that I really need anymore power above this things stock speed.

Yeah I hear you on that one. I've just been toying around. I had it up to +150 on the GPU last night with no issues. I might toy around with it just to see what 3Dmark 11 score I can get out of it. I can save those stable settings for a reserve later. +400 seems to be perfectly stable, but I see others are getting much higher numbers. I am not one for pushing the envelope to the limit, but I do like a good overclock that runs stable for the time I own the card.

You know that just comparing clock speed between different architectures means nothing right? Just look at intel vs AMD, at the same clock speeds intel still is better.

http://www.tomshardware.com/charts/x86-core-performance...

That is a comparison of a bunch os different cpus running only 1 core and at 3GHz. As you can see they all preform differently. This hold true for gpus as well.

That said, if you haven't seen any gtx680 overclocked benches how can you say that the 7970 outpaces it? Have you gotten a 7970 to 1300MHz? My gtx680 is running at 1280MHz

Ok here are some general benchmarks with 3Dmark11. This is with the below system.

i7 920 @ 4Ghz
Asus P6T x58
3x2GB G.Skill DDR3 1600 8-8-8-21

+150gpu/+400Mem: p9892
+200gpu/+400Mem: p10208
+200gpu/+500Mem: p10247

I usually use OCCT to do stability testing, but it seem not to like the GTX680. It hits a certain threshold and then underclocks the card. However, 3dmark runs just fine. I am planning to run BF3 for a little while at the highest clock, but apparently there is a 1.5GB patch, blah. I am probably planning to run a moderate overclock, +100gpu/+200mem. I don't think I'll really need much more than that for anything I'm playing. The +200gpu/+500mem hits about 1337MHz at full boost.

March 30, 2012 1:13:47 AM

Does you card limit the fan speed to 85% too? Mine is limited but
i wish it weren't so I could turn it up. It is quiet enough at 85% that I don't mind it.
a c 140 U Graphics card
March 30, 2012 2:42:47 AM

Yes there is a fan governor on most coolers.

I just played BF3 for 2 hours and it was running 75C with my fan at 65-68%. That was with a +100GPU and +200Mem. It was doing a constant 1228Mhz on the GPU that whole time. It never flinched from 60 FPS.

Because I read the Tom's Hardware Review duh.

Where did I say they were the same architecture??? I think your reading comprehension needs improvement.

I was quoting Tom's Hardware, so you can take your fanboy rant to them bud, sorry I got your panties in a wad. I'm also glad you were able to get in on the paper launch.

Quote:
Great! So, give me two then. Er, we’re sorry. GeForce GTX 680s are no longer available. Although there were plenty of entries for them at launch, they sold out within just a couple of hours. That probably shouldn’t have come as a surprise, given Nvidia’s competitive position against Radeon HD 7970. Nevertheless, we’re sticklers about availability, and the fact that you can’t buy a GTX 680 means that folks who simply cannot wait might want to consider a Radeon HD 7970 in the meantime. After all, there are plenty of them, and they generally seem to have quite a bit of built-in headroom.

Ah, overclocking. Don’t the Radeon HD 7970s retake significant ground in the hands of enthusiasts? They certainly can, yes. In some cases, a Radeon that would have trailed a GeForce, unmodified, may be able to outpace the Nvidia card after an overclock. When you take into account the fact that we hit Overdrive’s core ceiling of 1125 MHz and that folks have seen more than 1300 MHz from Tahiti, the potential performance gains are substantial. We’d really like to see AMD provide access to more aggressive settings. When its PowerTune technology is doing its job, settings that push higher than the board’s TDP should be dealt with elegantly anyway.

Performance scores in 3DM11 and 3DMvantage if you have them, sorry I didn't respond sooner went out last night, I see some are already posted Nice!

Please use the prefix so we know what test was run, because those prefixes assure the tests were equally run you know P for performance etc.

And nothing is as solid confirmation as the actual futuremark linked results, but you may want to wait for that until your overclocks are fine tuned, and that's just a suggestion.

I added a P to my results.

I had played some BF3 with the +200GPU/+500MEM setting for maybe 20-30 minutes and it seemed fine. It almost felt pointless as well because it also runs at the +100gpu/+200GPU setting. Heck it probably runs it stock.

I had downloaded that Unigine Heaven Demo, so maybe I can run a benchmark in that as well. I am starting to think that I may not even give much of an OC to this card at least until it is needed. The numbers look good though.

I wish I had your 680. I can't get mine to go over +175 even with +0mem. Oh well, luck of the draw i guess. Mine still works plenty well enough.

Anybody know if the core voltage offset does anything in afterburner yet? I have tried moving it but I don't see any difference.

Just a suggestion:

I had to supply some fresh air directly into my 580GTX air intake, did that with a side panel case mod and added a fan blowing fresh air directly into the 580s air intake, it made a difference in my situation, and may be a possibility for you.

You could have comparable cards but case airflow better in one case over another.

I already set that up when I had 2 gtx560ti in sli. My temps are fine, never seen it go above 69-70. Its weird though, it always fails at the same spot in the 3rd test of 3dmark.

So I ran the Heaven demo benchmark and the +200gpu/+500mem OC failed and crashed. The +150gpu/+400mem runs just fine over and over. I have some more testing and tweaking to do. I want to test the +150gpu/+500mem to see if the mem works fine at that clock. Will report back.

I own a EVGA GTX 680 and know NOTHING about overclocking think you guys can put me in the right direction. Also can you guys link me to some stress test bench marking tools so I can be sure that my 680 is running as it should. Thanks.

^
The GTX680 is a little different to overclock. It is the same principles though, however you have to take into account that it has a dynamic boost to the GPU now. Just do some reading. Maybe the articles I posted originally to get you started just to understand how the 680 is setup.

Evga has their own Overclocking software that you could download and try. I like the MSI afterburner tool. It works for non MSI cards to. I like it because it has an On Screen Display in games for FPS and temps. The offset we are talking about is basically the increase to the base clock. For example the +100GPU offset I mentioned is a 100 MHz OC to the GPU. This means instead of 1006MHz it will run 1106Mhz. However, because of the boost it can jump higher. You just creep up the clocks until you get artifacts in a benchmark or it crashes. Then turn back the clock maybe 25-50MHz or so to make sure its stable. That is just some general information.

Here is a good app I started to use with the GTX680.
Unigine Heaven DX11 Benchmark http://unigine.com/

I used to use the OCCT GPU test, but it seems to be a little off with how this card works. It likes to down clock to a very low clock if it reaches a certain power draw. I think I just have to play with it a big. However, for years OCCT was my go to test for a video card. http://www.ocbase.com/

Also, 3Dmark11 is a good benchmark to run. While it is not that great to test stability, it gives you a basis for how it is performing as you OC. http://www.3dmark.com/3dmark11/

Really appreciate all the info. I'll look into the links you provided and possibly post again if I actually get some overclocking done on this card.
April 6, 2012 2:31:34 PM

Quick question yesterday I ran 3DMark 11 at stock and my score was nothing compared to you guys (p8500 something like that) 3DMark 11 reported my card only running at around 700mhz core clock and 3005 mem if I'm remembering correctly. What do you guys think is wrong?
April 6, 2012 4:02:49 PM

3dMarl11 has never shown the card running at its full clock for me. The best way to check if it does hit the proper clocks is to open up MSI Afterburner and then run 3dMark11. You should be able to see what clocks it hit in Afterburner's graphs.

As for your 3dmark score, what are your other system specs? particularly your CPU as there may be a bottleneck in your system.
a c 140 U Graphics card
April 6, 2012 4:19:46 PM

^
1) Your score will also depend on the rest of your system. What are your specs?
2) The 3005 MHz for memory sounds right DDR (double data rate) means you have to double it for an effective rating. 3005 x 2 = 6010MHZ
3) 700Mhz doesn't seem right. You may want to download GPU-Z and check it there and see what it's reporting.
4) Do you have the latest drivers from Nvidia? There is only one released since the release of the card. I don't know what was on the CD that came with the cards, I never rely on that.

I think I've figured out why my score was low in 3DMark. Vsync had something to do with it I believe. I turned it off and my score went up but I'm gonna check it again to make sure.

Thanks for clearing up the DDR I don't know how I forgot about Double Data Rate I'm an idiot.
April 7, 2012 5:46:27 AM

On Stock this is what i scored on 3DMark just now P8942
That's pretty low compared to you guys.

I was able to overclock and got to +125gpu/+425mem: P9641

I couldn't do +150gpu it would crash running heaven dx11 and +450mem would crash as well
+125gpu/+425mem was the highest I could get stable with power limit at 132%

When I use afterburner it shows the core clock correctly when running heaven dx11 but in 3DMark the core shows 705mhz and the mem reports correct at 3005mhz and when I overclocked it showed the mem overclocked correctly in 3DMark but not the core.

Can you guys show me your scores after running heaven dx11 on stock and overclock with everything in heaven turned up to max so I can compare to mine. I'm starting to think somethings wrong with my card :cry:

When overclocked at the same offset your score is much higher than mine. So you think I was just one of the unlucky ones and got a card that doesn't overclock and perform as well as yours? I can't raise my overclock anymore the drivers crash.

I do have a MSI GTX 680 sitting in my room still untouched. I do have someone that wants to buy it off me for $575. Might keep it and sell the EVGA GTX 680 I have in my system. Wonder if they'll make a difference.

I would say its much higher. Both our cards at +125/+425 are pretty close. 2 avg. fps and about 50 points in score. Yours even had a higher max fps than mine. I would say that the only thing is that mine can overclock higher. The only difference that the MSI card you have might be that it "may" be a better overclocker. Then again it may also be worse than your EVGA. The only way to find out is to test both. Is this person that wants to buy your other card ok about it being opened?

Idk I'll have to ask to find out. How are your temps during these test? Mine don't go over 60c
April 7, 2012 7:36:13 PM

Mine hover around 65-70 at my settings of +165/+500. I have never seen this card go over 70. At +125/+425 it is more in the 60-65 range

So my temps are fine then. I have 2 front intake fans, side panel intake fan, bottom intake, 2 top exhaust, and the back exhaust. I wonder if when ivy bridge comes out pci 3.0 will be worth getting IB. Would it increase the performance of the GTX 680.
April 7, 2012 8:03:26 PM

No. The GTX680 isn't being limited by the pci 2 port. The new pci 3 ports are more for future graphics cards or high end pci-e based ssd drives
