I Im having some difficulty in figuring out why my FPS and benchmarks are so low when running SLI

Im running
Asus A8N-sli premium MOBO
Athlon 3500 (venice) clocked at 2.75
2 BFG 7800 GTX OC
Audigy 2
1024 OCZ pc3200 ram @ 2-3-6-2
Skyhawk PSU 620 watts.

My benchmarks are this in SLI MODE
3dmark 2001 ....................26544
3dmark 2005.....................11680
Aquamark.........................88332
Far cry I get almost 20 FPS more running on 1 card
Doom 3 FPS is the same.

It seems I get better result in the synthetic tests, but in game I get better results with one card. Why is this. Is it possible MY PSU THAT HAS ONLY ONE 12 VOLT RAIL screwing things up?

There are people out there with the exact set up getting 95-100k in aquamark. 12.5-13k in 3dmark 2005, 35-45k in 3dmark 2001.. and getting a heck of alot better performance in sli mode with games than I am..

any input would be great.

thanks

Have you overclocked the 7800's? Your scores there for the synthetic tests seem to be about right for non-overclocked cards.

To reach 12k+ in 3dmark05, you have to overclock those cards pretty heavily. Don't be confused that because the name of your card has OC in it, that it's actually overclocked significantly.

The BFG series overclocks a little bit just to get their product to look better, not enough to make a significant difference in much of anything.

I have basically this whole setup except for one 7800 and some Corsair XMS 2x512's.

I haven't ordered it yet, but I plan on getting it within the week, so I'd like to hear about this as well.

I was planning on getting: http://www.newegg.com/Product/Product.asp?Item=N82E16817103437


But if that is not good because of only 1 12V rail and screwin up SLI, then i might have to go for one of the newer ones =/

My setup is in sig and im getting 10,100 with a slower proc

The thing that irqs me the most, no matter how much i try i can only get 35-50 fps in bf2 with med/hi settings. :(

did you miss the part where he says his venice is overclocked to 2.75ghz? in anand's article when he introduces the 7800, he is "only" using an fx55. here is the link to him comparing doom3:

http://www.anandtech.com/video/showdoc.aspx?i=2451&p=9

anand gets better results in SLI, which should be expected. now lets compare the two cpus

fx55 - 2.6ghz/1mb cache vs venice 2.75ghz/512cache

does the lack of 512 cache limit his cpu? i highly doubt it. of course ram and timings is a variable here, but not enough to make sli worse than one gtx, unless u got like 256 or 512 or something.

what it probably is is something settings related or driver related. try updating to 77.77. i found those to be better than the official ones (i think 77.56)

and of course, latest bios, latest chipset, yada yada

it is much more likely a setting somehwere

Extremely simple question, but sometimes the simplest is the right one. You are selecting the proper profile through the nVidia Control Panel before running the benches/games, right?

It doesn't matter that much if your computer has 2 or 3 or even 10 12V rails. What matters is the amperage on each rail. For an SLI system like yours, I suggest a combined total of 38+A on the 12V line. Also notice that since you're running a 7800GTX OC SLI, you'll need more CPU power to feed those video cards with information.

i'm postive it isn't the cpu that is causing this...a 2.75ghz is able to get way more than 20fps in far cry...i'd say it's either a driver issue (do you have latest drivers? Did you cleaned drivers successfully? try other drivers?) or, the most likely, you have a bad psu.

Edit: just saw you had a skyhawk 620Watts, anyone know anything about this psu?
Edit2: Ok, i've just done a google search and noticed (correct me if i'm wrong) that there's only 20Amps on the 12V rail...well, if this is true, it might be your psu that's causing the problem

20A on the 12V line is barely enough for my router.
Get a PSU with 38A+ 12V rail.

Possible Solutions to your problem:

1) Get more ram, esp if you are playing BF2
2) Get a better CPU, not even an FX57 would make 2 7800GTXs sweat much
3) Try some driver roll backs and see if that works.

As Kensai said, make sure you have enough Amps through your 12V rail. You should be looking in the neighbourhood of at least 20A/+12V rail. Most PSU's don't even reach 20.

Amperage... is that a word? What happened to current?

No, I didn't, but thanks for being an ass. As you can see by my sig, I think I've got a better grasp on the situation than you, as I run an SLi 7800GTX with an FX55 @ 3GHz on a daily basis.

i saw how u had a flame war with bouzouki from another thread. i wasnt sure who started it, but now im starting to get an idea... :roll:

i dont see how i was being an ass, but i think you certainly proved that you are one.


edit: oh btw, im not impressed with ur rig at all.

I don't care whether you're impressed or not. I don't build my computers to impress others. Your comments were inflammatory, and implied that what I said was inaccurate. My point was very simple. You were wrong, as literally dozens of reviews have proven.

I too think your PSU is weak, however, Kensai I think 38 amps is a bit high. My Seasonic 600W only has like 34 Amps and it is SLI certified. I'd say anything greater than 28 amps will help.
