View Full Version : 8800gt sli prob

is it normal for me to have a score of 11k with 1 card on 3dmark 06, and then get 12k with 2 cards?:confused:
i have the q6600 OC to 2.67ghz, couldn't get it to 3ghz with my P5N-D board, it wouldn't post..
also 4 gigs of ram, but 3 since its vista.
i am using 169.32 drivers from evga.
the games that i play are cod4, half life 2 ep2, bioshock, stalker.
and i really quite honestly don't notice a difference with 2, or i may be just wrong.
the only game i saw a difference one, was practically an 80% avg fps jump on fear, from 1 card being 99fps, to 2 with 199fps. but other games i believe remain the same.
is my cpu the bottleneck as i read in other places? i cant get that sob to post at 3 ghz..*sigh*:(
well any help or advice would be so nice of u, thanks guys. l8r

dang yeah there is something wrong there. Yeah your quad at that core clock is the bottleneck. I would think that you should get a better score though then 12,000 though.
Some game scale differently with SLI. Fear is one of the games that works good with multiple cards. But I can't say the same for the others. But then again since the core is not that high you probably don't experience there full potential.

hey thanks for replying,
can you explain to me what the correlation of the cpu power is to the video card? u would think 4 cores even at 2ghz is fine, cause thats relatively 8? no?
and why is it that specifically at 3 and beyond, the gt's start getting better? and ive seen benchmarks where its a hell lot higher than my fps scores at like 3ghz, 3.15.
thanks again for help, im still a noob lol, but im learning! :)

I think that having the cpu at a higher clock allows it to communicate faster between the graphics cards and is able to actually process things faster between the games and the cards.
I know what you mean when you say technically it should be 8ghz with all cores combined but all cores are not going to focus solely on the graphics.
I think the cards are generally faster at 3 ghz because the quads speed has increased on all four cores. Thus whatever core interacts with the cards is going to be faster and is able to dish out orders. Just to show a comparison of my 3dmark06 scores
QX6850 @3Ghz with 1 8800 GTX 12,500-13,000
QX6850 @3Ghz with 2 8800 GTX 15,500-16,000
QX6850 @3.33Ghz 2 8800 GTX 16,500-17,500
Then just out of curiousity once I went to 4Ghz
QX6850 @4Ghz 2 8800 GTX 19,500-20,500
You can see how much of a bottleneck the quad is when you start to increase the core clock speed. As the graphics cards seem to be very powerful together. When I clocked that high @4Ghz my CPU points only increase by 1,000 or so points but its the cards points who increase by thousands.

You say your mobo won't post over 3Ghz. Have you tried going any higher? because that just may be a void in your mobo/cpu configuration and you may actually be able to have it stable at 3.2 or 3.4Ghz

sorry avalanche, i dont know how to overclock or what u r talking about :(
i made a new thread in "off topic" section, if u can help me there, thanks people for reading
