8800 GTX SLI Problems
Hi Guys,

I just put a new system together last night and I am having some problems getting it off the ground...

-------------
CPU: Intel Core 2 Extreme X6800 Dual Core Processor
Motherboard: EVGA 680i SLI
Ram: 4GB TWIN2X2048-6400C4 (4-4-4-12)
Sound: Creative X-FI ELITE PRO
Monitor: Dell 30" 3007WFP
Video Card 1# BFG 8800 GTX 768MB
Video Card 2# BFG 8800 GTX 768MB
Hard drives: 5 x Seagate 750GB ST3750640
DVD: Plextor PX-755AS
Keyboard: Logitech G15
Mouse: Razer Diamond Back
Power Supply: ThermalTake Thoughpower 750W
Case: ThermalTake Armor VA8000S (Black)
------------

In regards to my problems

1st) I noticed that my USB devices plugged into my dell monitor often fail every 30 seconds, its like they are disconnected then quickly reconnected.. its really annoying and do not have this problem when plugged directly into the usb panels on the back of the computer

2nd) Video cards FPS performance in games seem weak even running at 2560x1600 Resolution. Should I be expecting low numbers at this resolution with two cards in SLI?

3rd) My audio card makes strange crackling noises when I start to load up any game in SLI. I can hear it in the background of the audio, but after around 10 mins the audio completely stops until I reboot.

Any Ideas Guys? Thnx for the help!

When you say you are getting poor performance. Are you noticing performance improvements with SLI enabled and SLI disabled? Check games with it enabled and check with it disabled. Would help to determine if SLI is actually working.

Also have you tried onboard audio to see if it presents a similar problem?

Check the psu approved list ([url="http://www.slizone.com/object/slizone_build_psu.html#certified_powersupplies"]clicky[/url]), the thermaltake toughpower 750W is not certified for 8800gtx SLI, you likely getting voltage drop or lots of ripple on the 12v when you over load it doing 3d work ;(

Btw, congrats on being about the only 8800gtx sli owner i have seen so far who has listed a monitor that will make them work to their fullest ^_^
