SLI OC and Temps

[jcorqian]

I recently SLI'd my 9800 GTX. Using RivaTuner 2.09, I have OC'd the cards to 800/2000/2400 and put the fans to 70%. My questions are: does RivaTuner apply the settings to both cards? and is there any way to test for stability? I have been using ATI tool and that gives a ton of artifacts and then no artifacts every other time. Ntune is out of the question (BSOD every time). I know in Company of Heroes Gold I am not getting smooth gameplay or stability in the campaigns no matter what I clock the cards to. Seems to work fine everywhere else.

Edit: edited the OC to 800/2000/2400 (Core/SP/RAM) and I should mention that both my cards were EVGA factory OC'd. Sorry for sounding like I was trying to fry my computer, I was in a real hurry this morning before work.

the clocks do apply to both cards, but at those frequencies dude, you'll damage your card. Look at my configuration, I don't even keep it at that anymore. Your straining the card like hell at 800 especially since the majority of 9800 GTXs can't do 800.

Anyways to answer your questions, yes both cards are applied, Nvidia control Panel has a stability test option if you hav ntune installed.

Also try 3dmark, or cinebench to stress your card. You'll get artifacts I'll bet, I mean your memory clocks are insane, atleast put your fan to 100%. If you achieve stability I'll be surprised.

I'll say it again, your in the danger zone with the clocks. My opinion

l1qu1d the 9800GTX's 0.8ns memory is rated at 2.4Ghz by default, i seen many of them goto 2.5 or even 2.6ghz.

is the 1200 the stream processor or the memory at single rate?

the highest i have seen is 800/2000/2600(Core/SP/RAM)
but i see most stuck on 780/1950/2500(Core/SP/RAM)

Exactly my point, majority moves around 780, and pushing the memory soo much is scary. I think that its unnecessary to achieve what is around 1-2 fps more.

 

[iluvgillgill]

in his spec i dont get which is which.800/1200/2400

so is sp running at slow ass 1200?or screaming 2400?

 

[L1qu1d]

I duno either. For my GX2 I can get it to 1200(2400 Memory), but it artifacts lol.

I don't think the core and memory clocks are unreasonable. I have them clocked the same on my 9800GTX and it runs stable 24/7 with 70% fan speed (it runs as cool as my CPU) and no artifacts. Have never tried shaders that high as I kept the core and shaders linked when I OC'd using Rivatuner.

 

[mothhive]

I think his clocks are listed the same way as mine (the order they are displayed in GPUz) Core/RAM/SP

(sorry about double post, it won't let me edit)

 

[iluvgillgill]

2400 SP??oh my!i never seen that high.oh well.

 

[L1qu1d]

hmm weird my GX2 only goes to a max 2250...

 

[iluvgillgill]

because the GX2 use the same memory as the 8800GTS 512. so really Nvidia have differentiate 8800GTS 512 to the 9800GTX in terms of memory and bandwidth.

 

[L1qu1d]

bastards, they make another revision like a 280 GTX+ I swear I'm nuking their facility

 

[iluvgillgill]

well thats the 55nm GTX 280!lol i wish they do really put GDDR5 in them. so the real battle will start out with the 4870X2. of because hope it doesnt melt itself first. i seen review of the HD4780 loaded at 93C with working Auto fan controll.

 

[L1qu1d]

lol wow who wants hamburgers

Did you see the video of the guy cooking an egg on the GX2 with fan set to low? LOL

 

[iluvgillgill]

nope!link??

[iluvgillgill]

its bate that video. its obvious that ther person heat the pan up beforehand.

 

[L1qu1d]

I still think its possible, think about 100 degrees if you leave it on it can be done I'll try it one day when the GX2s are worth 1 penny

 

[iluvgillgill]

if a SLI GX2 with the card housing remove then it might be possible. you wanna make your own video to testify?

 

[iluvgillgill]

i sure it worth more then 1 penny at scrapyard.

 

[L1qu1d]

 

[iluvgillgill]

or i will buy it of you for double the price 2 penny!!deal?

 

[L1qu1d]

No dice lol 1 millions dollars

 

[iluvgillgill]

quick fried egg FTW!LOL

Sorry, I should have specified that both my cards are EVGA pre-overclocked so I don't seem like an idiot pushing my core speeds up by 130 lol. No, one is the SSC and the other is the KO, and I am thinking I will only OC to around 780 or so to be safe. Was in a big hurry this morning. I am currently at 780/1970/2430.

Ntune will not work for me and are there any alternatives to Cinebench or 3DMark? Can I get 3DMark free?
