Not seeing much from Tri SLI versus single GTX 470

post #1 of 28
Thread Starter 
I've looked through the stickied threads in this section, and I've searched around some. I can't find a similar enough thread, so here's something that may be original:

I just installed three GTX 470 cards, and I've had two 470s for about a week. I tried benchmarking with a single 470, and the results all three times are the same FPS that I'd get with a single card.

The benchmarks so far are Mafia II Demo and 3DMark 05 since that's what I've got installed. What should I do to troubleshoot? Thanks!

Did you manually enable SLI after installing the 2 other cards? SLI is disabled by default after every driver installation.

Also current drivers aren't "optimized" for ancient benches like 3DM05. If SLI is enabled, try something more recent like Vantage or 3DM11.

Yes, I went to the control panel and enabled SLI. Also, my driver version is 280.26 - forgot to add that in the original post.

I just ran Fluidmark, saw temps rise into the 60s to 70s across all three cards, ran 76 FPS in the default benchmark, and got a score of 461. I'll go download Vantage and 2011.

I would do what above has said.

But why on earth would you need tri sli for 1920 x 1080 !

sick rig btw.

Tri SLI is cool, but I do F@h too. With F@h, the more cards you have, the better.

Thanks!

Use Haven benchmark and check this thread.

You should notice a difference i know i did, around a 30% increase.

*For benchmarks i just lock my GPU fans and CPU fan at 100%

*Vantage Benchmarks are really cpu based

Thanks! I'll try out that benchmark. Currently downloading and installing 3DMark 2011. By the way, your sig PC is amazing!

In Windows' Device Manager, are all three GTX470s properly recognized without a yellow exclamation mark?

And, in Nvidia Control Panel, do you see something similar to pic below?
(do not pay attention to the 260 vx 285 Physx bug)

A little forward looking when you get the 3-way SLI working:- For your 1920x1200, I expect you to often run into severe CPU bottleneck when you game. I suggest you overclock your i7 920 to at least 4GHz region. And remember to use a good aftermarket cooler if you are still using the stock Intel heatsink-fan.

And here is a review of GTX470 2-way and 3-way SLI. Use their numbers as reference for yours:-

I'm back from benching, and I have results. The Heaven benchmark is the greatest jump I've seen so far - up to 80 from about 25-29 FPS!

Hey, windfire! Thanks for the explanation. Yes, in Device Manager, all 3 appear with no exclamation marks. The nVidia CP shows that picture, and that's the view I've used to enable/disable SLI.

The SLI has been working, but it seems I am just now learning that not all games support it too well. Looks like some games will give me no more than single GTX 470 performance while others will look awesome. I actually heard about this from a friend of mine who had a 9800 GX2, but I forgot. It's all coming back to me.

I'm definitely going to overclock the 920 I have. It's the Bloomfield version, and I bought it used after a few weeks of searching for the most overclockable for the lowest voltage Core i7 I could find. All I need is my water cooling setup to be complete (looking for parts across several large boxes, unfortunately) because the slightly-improved-over-stock heatsink I have now isn't doing the best possible job.

Thanks to everyone for helping! I've solved my worries by realizing SLI's limits (assuming Windows 8 Dev Preview doesn't add restraints). This has been a really quick and very awesome thread.

Last thing, interestingly, that's exactly the review I had read a while back while anxiously waiting for my 1200W PSU to arrive.
