I have an Abit kn8 sli motherboard with the nvidia nForce4 sli chipset. Does anyone know If I can run pcie 2.0 video cards. Thanks.
 
thanks. the reason I ask is because I have 2 asus 9600 gt's that freeze my system. I bought them at new egg open box. they didnt come w/ the split power cords. I bought 2 cords on ebay but they only have one connection each. the seller says they are designed to work only using one 4pin connection. could lack of power/current be my issue?
 
my power supply is a coolmax cx550b. 550w max output. I couldnt see a total current but if I add up all the legs its 120a. I have the abit kn8sli mb, fx60 cpu. 2 opticals, 2 sata hd's/raid. a pci soundcard, 2 gig of crucial 400 dual channel matched ram, and a floppy. currently Im running 2 nvidia 8500gt videocards and all works well. I installed 2 asus pcie2.0 9600's and my system boots fine. I was able to download and install the driver but as soon as I opened need for speed undercover my video froze solid and I had to hard boot to recover.
 
i assure you you dont have 120A on the 12v rail...

550W is a little low, especially seeing as its not a great brand (good brands: Corsair, PCP & C, enermax, antec)

I would get a Corsair PSU.


Plus, GFX cards need 6pin, not 4 pin plugs (unless im mistaken)


Also, any motherboard can run any card (PCI-E on PSI-E, no mixing AGP etc). Just it wont run at full capacity (granted the performance gains on PCI 2.0 are medium, about 1 - 10 frames)

That Coolmax has 30 amps on the 12V rail, your pushing it with two 9600GT/ two harddrives/ two CD/DVD drives/ processer.
 
you think a larger power supply is my answer. What do you think about the power cords I have on the video cards? they are 6 pin to only one 4 pin each as opposed to the split ones. http://cgi.ebay.com/ws/eBayISAPI.dll?ViewItem&item=270317647833

That link is dead. I would get at least a 650 watt powersupply with 20 to 30 amps on 12v rail and having at least two 12v rails. Good brands are antec, pc power and cooling, corsair and ocz
