Gigabyte GA-45 DS3L - no monitor signal
i'm working on my new system. The build is: Gigabyte GA-45 DS3L rev. 1.0 Core 2 duo E8600 3,3 ghz Sapphire Ati Radeon 4870X2 4 gb Kingston HyperX DD2 Dual channel 6400 The problems is that i do not get any monitor signal at all. I've tried to disconnect all the componens except the GFX, and it doesn't help either. What can be wrong?

Re: Gigabyte GA-45 DS3L - no monitor signal
What PSU are you using? Is it able to supply the huge current for two crossfired HD4870 cards?
Are the both rear ATX 12v input connected? Did you tried a boot with one single card installed?

Re: Gigabyte GA-45 DS3L - no monitor signal
Can you post your PSU specs? Are you sure you connected the additional power cable to the graphics card?

Re: Gigabyte GA-45 DS3L - no monitor signal
For sure that Corsair PSU is able to feed this internally crossfired double card.
The connector I mentioned is that one black eight-pin in the picture below. It should be connected to the PSU and I think that Corsair PSU have the appropriate cable and plug. Otherwise, a special cable is supplied with the card and it can be plugged in one of HD drive power supply wires. Without that 12v there will be no video.
