8800 GT SLI

helo i have both of these cards and i dont see any increase in performance in 3dmark 06 i get 13800 with sli and without sli 12800 do the difference is small amount in games like cs and crysis the diff in fps is very small 30-40fps only why any settings wrong installation for the cards need to know

Your getting a 30-40FPS increase?

I would say that would be pretty good depending on what resolution your playing at. At high resolution on max settings with a single card and then getting an additional 30-40FPS, I don't see what the complain would be.

Give us more information. What resolution your playing at?

SLI doesn't double the performance of a single card, just know that. I think the general consensus is that usually you'll see an increase of about 30-60% in performance. In some games that are not optimized for SLI you may not even see an increase in performance. If your playing most games without any problems you'll be fine.

no i meant was from 30without sli 40 with sli crysis 1680*1050 but in counterstrike i dont see any diff both on and off same fps call of duty the same wat are the settings to be done

maybe Vsync is on

Actually, SLI scales at about 30% increase in performance, except for some very new games which are Nvidia optimized which could get you up to 50% increase in performance. From 30fps to 40fps in crysis 1680x1k rez, I'd say that's just about as much as you should expect to get (a 33% increase). If you thought a second GT in SLI would double your fps performance, you should have done your homework before buying!

in CS you probably have locked FPS.

And Crysis case is strange, you should see more benefits from SLI. Check if SLI is enabled for the game, upgrade drivers, etc.

Reply to Vorador2

CS may be CPU limited. How high are your framerates already?

Crysis, you are right on without enabling eye candy with a 33% increase. If you enable 2xaa in game and force 16xaf in the drivers your gains will go above 50% (55% for me). And then you see settings completely unplayable with a single GT become playable in SLI.

SLI doesn't scale all that well in 3dmark06. 13,800 is about right for stock clocked cards and default driver settings.

Anyway, you need to look at what SLI can do for you in offering better playable settings in games. Being stuck at 16x10 resolution, it isn't going to offer much unless you go for max IQ with high AA/AF. If you don't use aa/af SLI will be a waste IMO.

It could be possible you have a CPU bottleneck? What CPU are you using?

Open 3Dmarks06, and change the test settings to your screen's resolution, turn up AA & AF, then compare SLI vs. Single-GPU score. Who buys SLI to play @1280 0xAA 0xAF anyways? Its no surprise you dont notice a difference, one card alone can blast through any thing at those settings.

Test 3dmarks06 settings...
1680x1050
4xAA
8xAF

comeback and compare #s

Now for weak performance in games... Never exceed settings of 2-4xAA, and 8xAF. In crysis never force on AF. 16QxAA and 16xAF are really meant to be used when playing very old games...Diable2...CounterSTriker....etc.

hey man, wat kind of motherboard do u have? how much ram? ur processor? which chipset on ur motherboard? these have to do alot with unleashing ur optimal performance.

You really might be CPU limited a little...in the sense that your processor is negotiating some of what has to be rendered on what card.

If you're using the free version of 3dmark06, so whatever the default settings are since you can't change them.......I'm getting 13,930 3D marks on my single OCed card and CPU

thats 650 core 1900 mem 1625 shader on the card
3.3 ghz CPU
plus the FSB and ddr2 runnings a little faster of course

are both the PCIe slots 16x on that board...

Its normal that SLI doesnt score well in default 3dmarks06. My 8800GTX SLI Setup gets ~14000 single card, ~15600 dual card. Turn up the resolution 1680x1050+, AF & AA and you will see SLI scale much better. Your scores are nothing to worry about in my opinion.

About the games... what resolution do you play at...what AF/AA Settings do you use...

Overclocking your CPU/GPUs wouldnt hurt either +10-15% performance gains there.

hey man, nice comp. iono why you would be having problems with that hardware. dont listen to PlasticSashimi, he apparently doesn't know what he's talking about. "are both the PCIe slots 16x on that board..."

Yeah, don't listen to me...WTF!

I have 4 PCI express slots on my board....two that run full 16x, a third crippled to 8x, and a standard 1x (I don't know why that was such a wild statement) I simply didn't want to bother looking up that spec on the board you had....not really sure if having one 16x and one 8x would really make a difference anyhow though, since the bus bandwidth is unlikely the issue here.

I still say an OC on your proc will help your 3D performance the most, for crysis make sure you have the 1.1 Crysis patch and latest beta drivers from nvidia.

At least I'm trying to analyze your situation...dankcomp's high a** just sails in here to explain to you that "iono why you would be having problems" ....that and to jab my nerves, sheesh.

if ur saying this wat i get in sli ok how to overlock with rivatuner software to wat mhz etc

Overclocking the cpu and gpu will increase your 3dmark score. Some people mover their driver IQ to performance (looks like mud) and do other tweaks specifically for 3dmark. Don't worry if someone is beating you. Pick a review site that tests at stock speeds and base your comparison from that. Fudzilla got 12K with one OC'ed and 13.7K with two both clocked at the Alpha dog speeds. http://www.fudzilla.com/index.php? [...] &Itemid=40

Like I said, your 3dmarks are on track. If someone with one card manages to beat you, so be it. It's default 3dmarks, who cares. Did you buy SLI for 3dmarks? Turn on fsaa/AF in crysis and your setup will spank theirs, being way above an 8800 ultra at those settings. Max out Oblivion and enable 4xaa/16xaf and SLi struts it's stuff. Isn't it better that it scales well in game compared to default 3dmarks?

I do agree with pauldh...the 3dmarks dont't really matter...

I was just trying to get you to see that OCing just your CPU might help alot. When you run SLI there are instruction sets that your CPU must do to tell which card what to render.

Plus Q6600s overclock really well, you just need something better than the stock cooler. 35-50 bucks tops.

my system: amd phenom 9850 (OC to 2.75) asus sli ready mobo, 700 wat psu sli ready, 4 gigs ram, 2 8800gt's in sli.

ok, i really need help, i have 2 8800gt's in sli and im running crysis on MEDIUM with NO AA, at 1680x1050. im getting between 15-25 fps, which from what i have been reading is HORRENDOUS!!!! i have all the current patches and drivers, and i am SURE that sli is ENABLED from nvidia control panel.

HELP!!!!! PEOPLE WITH WORSE GRAPHICS CARDS AND NO SLI ARE GETTING BETTER PERFORMANCE!!!!! AAAAAAAAAAAAAAAAGH!!!!!!

Reply to fantom-feltpen

SLI can get way more than 50% scaling!!!! OMG WTF look at this:http://www.anandtech.com/video/showdoc.aspx?i=3341&p=13

that's around 85% scaling ffs!

Reply to V3NOM

ok wtf!!!!!! according to that link im supposed to be getting 46.1 fps on high/very high!!!!! AAAUUUGHHH!!!! on MEDIUM im getting below 20 most of the time!!!! that is like the performance of a SINGLE 8800!!

what can i do???? any helpful tips?
