Sorry bait your gonna have to update my score again buddy. Smokin I was playing around with the overclocking today, ended up setting it with the same overclock as you seeing that we have the exact same card and I scored pretty well. Thanks for the overclocking tips, worked well.

No problems and great score mate!

Found out that nVida have put a power draw limitation on 3d mark 2011 for this card when overvolting. So even though I can overclock to 750mhz and get great performance in games I get throttled in this benchmark. Hence my 750mhz score being less than my 700mhz.
About to test some old drivers that I believe 3dmark11 do not throttle.
So it's really gonna be an issue of does the extra 50mhz off set the fact i'm running old drivers?

Ok Bait can you edit my score please.
This is the best I can do atm and there will be no massive gain. Nvidia don't want this card to work when overvolted with 3d mark2011.

Done, lol Nvidia playing benchmark police, thats a new one for the books...

The GTX 690 thread and talk on power consumption inspired me to give it another push.

Gung-ho - P11679 - 2600k @ 4.2GHz / 8gb G.Skill RipJaws X @ 2133Mhz (11-11-11-30-1N) / SLI GTX 480 @ 850/1700/1848MHz

Wow nice improvement. You are hardly pushing your CPU too.

You want more, you'll get it. Oddly enough even with the increased cpu clock I didn't see a higher power draw.

Very impressive Gung-ho!! 4th spot on the ladder is yours

Nice one Gungho, I thought I'd have a crack at your score.
I got my cpu up to 4ghz but it actually dropped my score a little and my cards no likey being pushed more than the clocks 841/2042/1682.
Guess thats what you get with cards that come o.c out of the box (795/2004/1590),no head room and at least I know(guess) its not the cpu and mobo holding em back.
Until gaming demands more I'll be content with what I got, then I'll have a new build and take a crack.There will probably be a new benchy by then and I hope Bait gets a new ladder goin for that.
p.s. cheers for doin this **** Bait,this busted **** forum needs more positive dudes like you doin their thing as opposed to the purile although admittedly entertaining **** what goes on G.A.

Odd that an overclock would drop the score.

Usually the better quality pre-OC models that have a custom PCB/design usually overclock better because they have better voltage management and are often cherry picked gpus. You have tried bumping the voltage up further on the gpus right? One annoying thing is of my two GTX 480s the Zotac is the better chip. It can run stable with a mild overclock at .963mV whilst the Asus can have no overclock and requires voltage of .975mV.

You could also be hitting a power limit-down throttle as it seems your system is backing down - overclocking cpu further = performance decrease/unable to OC gpus further - could simply be the PSU has nothing more to offer.

Well I was hoping to not change voltages on my gpu's but I'll do a bit of research on that and see what I can do safely.
As for the PSU I have an Antec 1200 truepower Quattro wich should be sufficient.
Besides the mobo, ram and cpu it only has to power one (almost 5 year old) HDD, one dvd burner/drive, 2x 200mm fans 2x120mm fans and a H70 cpu cooler with 2x120mm fans.

Not a fan of Antec PSUs anymore but that should definitely do the job. Really quite odd that the extra cpu overclock decreased performance. If you really want to bump up your gaming performance as a general rule you can disable hyperthreading and ramp up the clock. Not too sure how 3Dmark works with hyperthreading though. Actually what is your RAM running at?

When it comes to overclocking vid cards I suggest only overclocking the gpu and not the memory. In my experience memory overclocks yield little whilst being more dangerous.

GPUs are fairly sturdy and can take punishment far better than cpus.

My 850MHz OC requires 1.05V for stability. Reference stock is 1V for the GTX 580/480. Guessing by your clockspeeds you are running a Gigabyte 580. Not sure 100% but I think that runs 1.025V stock. You must have a good set because many seem to need about 1.063V to run @ 800MHz long term stable.

Well I've done some more testing and the decreasre is not due to the cpu clocks, I,m consistantly getting 2-3 more fps on the physics and 4-5 fps more on the combined, disabling hyper threading actually dropped both of those by about maybe 1 fps.
My ram is Corsair dominator running @ 2000mhz 8-8-9-24-2n.From my hazy memory this is the recomended settings, I remeber changing them from the mobos default but I'm not sure if this is what I changed them to but it's what bios shows.
Yes both my cards are Gigabyte, no. 1 card is the oc model but the no.2 is a revision 2 and maybe the reason I can't get more out of the pair.
Gpu 1 has a 1.025v as default Gpu2 has 1v as default, I have a feeling that Nvidia control panel forces both to run at 790mhz the stock speed is supposed to be 772mhz.

Also when using msi after burner it's showing that gpu2 is throttling down even after i've put the volts up, I didnt go any higher than 1.088 because of the temperature card 1 was getting up to 90 degrees plus which is no surprise as it was the one getting pounded while gpu 2 was not being used.
Is there a stress test better suited to sli.

Next time I clean dust out I might benchmark the cards separately.

Yeah wasn't too sure about how HT worked with 3dMark. Seems it does its job well but at the same time that doesn't mean HT is good for gaming (the general rule is 4.2GHz w/o HT > 4GHz with HT > 4GHz w/o HT for example). Your memory is good.

I'm assuming you are using MSI Afterburner to adjust voltages/clocks right? If not you really should as it's more functional than nVidia's software.

Voltages/clocks should always be the same. Even if one gpu is idle they're settings must always be matched. Keep in mind when the cards are running in low power mode there voltage will drop and changing the low power voltage is more complicated. Funny story being my Zotac GTX 480 could run under load at .95V which is lower than the low power .963V hehe.

If your top card is running upto 90 degrees you might have an airflow problem with your case. Those triple fan coolers are great for a single card, but are very dependent on good airflow in SLI.
Are they both the triple fan cooler?

yeah until i installed MSI afterburner, on the advise of one of our good ppl here, i was getting crazy GPU temps because my 580's cards fans were lazy as ****: "oh our cards up to 80? might decide to go up to a whole 5 rpm mmm after this sammich"

its all good now i got those guys on the program no issues since then

but in your case sli is just a hassle and the real world gains (in game performance not benchmarks) dont seem to off set that hassle of using dual cards

Yeah I am using MSI Afterburner, I was only using nVidia when not changing voltage as it does not allow it.

yes they both have triple fans but the way the mobo is set up they are very close together.
The airflow seems o.k in the case.
The cae is a cooler master HAF 922. Front fan is a 200mm blowing in unobstucted, top fan 200mm blowing out with two 120mm fans blowing in from side through grill.Also the two fans that cool the out of the box cpu radiator blow out through the top of back.
The psu is also quite close to the bottom GPU and almost obstructs the bottom pciex16 slot, at one stage I thought about using one of my GTX 470 cards as a phsyix card but thats just more heat and it looked a bit of a tight fit on top of the psu.
I could rig up another fan internally blowing from the front of the gpu's and change the way the air flows. Any suggestions?

I don't consider sli a hassle it's all part of the fun.
The overclocking side of it is just another side of the enjoyable hobby that owning a p.c. can be.
Also sli or crossfire ( I guess ) actually does have a big enough impact on gaming performance for me (not everyone) to be worthwhile.
I got a good 4 years out of a rig using GTS8800 640mb cards in sli with a Q6600 by overclocking.In the process I avoided buying **** repackaging of the same gpu.
The only negative was putting two GTX 470s in this rig to start with and having something sound like a **** jet blister the paint off the wall from half a meter away, but those two cards smashed any single gpu nividia card at the time.

Stop with the double posts already.

He's making up for lost time.

double post is 'cause I start a post, forget what I was doing, send it then come back and read it after some ones posted before and then reply sort.
Any way it's a bump for the thread.
Also double post is posting is more when you post the same **** twice by mistake, so circa go **** some more.

I think circa was joking

Now to learn how to overclock these new beasts.

great score, now oc those suckers

http://3dmark.com/3dm11/3377525

Pulled an mid overclock on the gpus ( i think) but I really have nfi what im doing, it's heaps different to the 600 series...
Will have a go later, bf3 time.

2 680's now, thats the ****!

**** they run cool as well 54 and 48 in bf3 lol.

Mitch are you over volting at all? Have you got a link to a good guide?

Hmm that's cooler than most people would report them as. What fan % are they running at?

Keep in mind the GTX 480 and GTX 580 had a better cooler than the 680 (and needed a better cooler). The 7970 also has a better cooler so even though it uses more power/generates more heat it runs cooler/quieter than the GTX 680.

Nice score btw =)

case side is now on and the hottest i saw gpu 1 (top one) was 60'c thats after 2 rounds of bf3 on ultra in perth, just then. i am running a custom fan profile but it's far from extreme. pretty much the same i ran on my 590.
my 590 would get to about 72 max in bf3.

the gtx680 reference design is hardware limited to a max of 1.175mv as far as i know

and yeah the hottest these 680's get is mid 60's after the hit 70c they start to auto downclock, what boost clock are you getting on your core in mhz?

mine sits at 1234Mhz with a +150Mhz in evga while playing bf3, im so **** that they dont have any more gigabyte 680's instock

Seems temps were the problem(much cooler ambient room temp tonight).
Would have a crack at dasa but it's past my sleepy time and I'd be **** uphill and into the wind against the keplers.

Tbh mitch i have nfi how to work presicion x, i'll have a mess around on the weekend.

LOL, you guys have been busy!!

Congrats on the new cards and great score Audi! So that's 4.8 on the CPU and what on the GPU's?

Nings really nice jump mate and Smokin well done, every little bit helps.

Keep'em coming guys...

ordered my second gtx680 today hopefully get it delivered tomorrow, but more than likely monday or tues

Long time no see Bait!

Yeah mate I thought it would be nice to take a long weekend holiday to hinchinbrook island after all the stress from family court, but met a nice chicky babe and decided to stay a bit longer lol.

Cheers for the info, those 680's are beasts I bet BF3 runs smooth as butter.
Are you gonna pass your old 590 onto Joe?

You sexy beast Bait, getting your end wet all over town. Hope it help clear ya mind.
Yeah Joe is gonna pick up my 590 on the weekend. He's gonna have a quad gpu monter, he's just waiting for a 1200 psu that should be here next weekend I believe.

Hahaha, yeah feeling pretty good, life doesn't suck as much now lol.

Joe with all that horsepower and I bet he won't do a 3Dmark score!! its not the size of the e-penis that counts, its how you use it lol.

haha, yeah. this quad settup is just to tide him over till he can score 2 690's.
