Sli not working =( help?

[Solemn]

Hi,

So I have the Asus Rampage II Extreme. I also have two MSI FrozrII 470 cards. I'm trying to sli them but seem to be hassles.

First of all, I have tried the cards when not in sli mode and both of them work fine but when i enable SLI in NiVidia's control panel by selecting "Maximise 3D performance" instead of Disable SLI I'm having issues. In Windows all is good and well, but when I try and play any game after about 30 seconds i get a black screen, and sometimes it comes back but eventually it just crashes and i need to reboot. Any Idea what I might have done wrong?


My doubts are,

Am I using the correct sli bridge? My cards have like a double bridge on each but the bridge i seem to have only has one? is there a reason for this?
I have the cards in the 1st and 3rd PCI slot on my board (for better air) is this ok?
Do I need to enable anything in bois for sli to work?
Am I enabling it correctly in the Nvidia Control panel?

Any other suggestions would be great... as you can probably tell by now i have never used SLI before so I'm hoping its something silly like not enabling something in bios maybe!

Thanks!!!

Are you using that OCZ 600w psu for them? if so that will be the issue.

 

[Garonazz]

Sounds like a PSU issue to me.

 

[Solemn]

using a BeQuite 1200 PSU, but it is a concern of mine that my psu may be faulty, anyway I can find out for sure?

lol, I have this issue with 3 570's under a 850watt psu, I am blaming the psu though lol. An upgrade is in order. Have you tried a diff one?

Sli 470 draws approx. 579w playing Crysis and 740w running furmark.
600w psu is clearly not enough, would want 850w for future proofing.

I like how the last 2 responders haven't read the entire thread.

I like how you're trying to get your post count up without offering any useful advice.

I apperciate you guys think its the a power supply and im not saying it isn't... but my power supply that i am using is a BeQuite 1200W as stated earlier.. I dont even own a 600W PSU anymore that was from an older build of mine that I no longer have.


anyways is this a common issue with fault PSU's Because I ahve both cards plugged in and power going to them without a problem right now. I only see crashes when turning on what I think is the SLI option in the Nvidia Control panel and the trying to play a game,

Games I have had the crash in are
WoW
Rift
BFBC2

Anyways I'll be greatfull for any help... Thanks.

Make sure you're trying to enable SLI properly.

See if this guide helps:

Also make sure you have the latest drivers.

This chap also had problems enabling SLI and the latest Beta drivers sorted it:

You'd think if that I actually cared about post count I'd have more posts than I do currently respective to the amount of time I've had an account!

But it was usefull, he was merely trying to point out that the OP is not running a 600W PSU which other posters had obviously missed. Get off your high horse

Wow, his post was usefull, what's the problem I pulled you up on your quite frankly uncalled for comment, now you trawl through my posts and start on me.
Have you really got nothing better to do on a Sunday afternoon other than annoy fellow forum users?

No as they're supplied with motherboards.

I'm sure if you do some searching you'll find plenty for sale.

Get a flexible one as it'll be easier to use for varying card spacing.

Ocuk dont sell them, but they can be bought on the big auction site.
