3870 X2 Big Problem

zadcodrin · 08-20-2008, 07:46 AM

Hey peeps. First time posting here so don't judge to harshly. I just got in my ATI RADEON 3870 X2 today and it does not work. My pc is kinda old have a Athlon xp 4200 +, asus Mother Board, 2 gb ram, 450 W source. Installed it by plugging in the 6 pin cable in the 6 pin slot on the Video Card and 2 red lights are permanently on. When i plugged in the 6 pin in the 8 pin slot on the Video Card just one was on. But both times no display on monitor. When I connected my old ati radeon x1550 series back it worked. So what would be the problem. Thank you anticipated!

there is a very high chance your power supply is not putting out enough power get a better high quallity 650 watt

Your way underpowered.

You need a Antec trio 650W, but i would highly recommend a Thermaltake toughpower 750W or a PC Power and cooling 750W

Thank you for the answers. Did that and still no display. got the thermaltake now. When I insert my old graphic card there is display but with the 3870 x2 no so luck. Could it be the pci express 2.0 on the graphics card and the older pci on the motherboard? Thank you!

the ati cards are backwards compatible
do you get anything in safe mode
i would be running a 850w

for a 3870x2? I would think 750 would be enough, even if it's a dual card?

Got it then! Looked on the ati.amd support online and found something with bios and registry tinkering. I managed to make it work. Thank you for the help! :)
