XFX nForce 680i LT SLI Troubles

[dreamsiren]

I just bought a XFX nForce 680i LT SLI motherboard and I am having issues. I am trying to troubleshoot, but without much luck. I am not seeing anything on a screen and I am not getting a keyboard light. The motherboard is getting power. I can see a blue, green, and yellow light and the fans are turning. Can anyone give me some tips on how to troubleshoot this motherboard? Thanks for your help in advance.

Do you get any POST beeps?

Post the rest of your specs.

[dreamsiren]

Nope. At far as I know this motherboard doesn't respond with beeps. By the way these are the specs for the computer:

Antec P182 chassis
Solytech 600W ATX12v PSU
XFX 680i LT motherboard (no onboard video)
2x 1gb Corsair PC5400 DDR2
WD 250gb SATA2 HDD
BFG 8800GTX GPU

I ran into the same problem with my new 650i ultra...that is until I figured out I plugged in the power switch 2 pin connector into the wrong slot(the really confusing part with like HDD, LED, etc.). Try that.

Hmm.. Well I tried switching it around every way, but no success. I don't think that is the problem :(

I am having the same problem.
If you have any luck please post, I'll do the same.

specs:
XFX 680i LT motherboard
Intel Q6600 2.4Hz
2 gig Corsair PC6400 XMS memory
XFX 8600 GT 256mb video card
seagate 400GB sata HS

You might try boot to a single stick of ram and then manually setting the ram specs and voltage in the bios. Same thing happened with my board on first boot.

Looks like the mobo is working correctly if this is the same post as: http://www.bjorn3d.com/forum/showthread.php?t=14664

Have you checked to see if your motherboard is capable of using ECC registered RAM? Is that in fact what you have?

I've just set up a system with an XFX nForce 680i SLI and the RAM in it is ECC registered but I'm told by XFX the motherboard can't use it. It should still work, just not using it the registration but my system won't start at all, power is on etc, but I get a long default beep every few seconds while it's turned on, but no reponse at all from my monitor.
I'm searching even now to find the answer, so please let me know too if this helps!!

Sory for the late reply, but I just got my board a few weeks ago and had the same problem. I found that the manual that comes with the motherboard is wrong. In the pin section on the motherboard where you connect the front panel lights and power button and hdd light and what not, you need to switch the power button wire with the power light wire on the board. I had to re-pin the power connector to make it work, but it works. Hope this helps.

zigsman, how did you re-pin the power connector? On the Boards manual the say that if its a 3-pin connector you have to remove pin 3 or cut(?) position 2.
I really need some help with this1

[XFXTechSupport]

If your Power LED connector has 3 pins, you basically need to cut it down the middle where there is no wire connection so it turns into 2 single pin connectors. Then connect those to the pins on the motherboard.

Having basically the same problem.

800W Power Supply
4x DDR2 Corsiar
Intel Core 2 Quad Q6600
Corsiar Water Cooler
2x GeForce 8600 GT video cards


Blue light comes on, when the power supply is plugged in.
Yellow light comes on when I hit the power button,

No POST, no Fans, no nothing.


Thoughts?

I have the same problem as Trevize. Called XFX and they keep saying that it has to be my heatsink shorting something out but my heatsink is isolated with nylon and rubber washers. Sent it into XFX and they said that everything is working on the mobo. Just received it again but nothing! And I even have the mobo suspended on nylon washers. Don't know what the problem is. Still trying to figure everything out....again!!
