drivers and PCIe adapter questions


Recommended Posts

hi, I have a few questions with my new build.

 

I have dfi nf4-sli-dr mobo, I have instlal all the drivers from nvidia and the dfi's site, but I still couldn't run usb at usb2 speed(I have already updated everything from MS as well). I checked under hardware properties and it seems that for some odd reason, I do not have USB cotroller (show the yellow question mark symbol) as well as some weird PCI bridge device and PCI memory controller(where can I get the driver for these things?

 

I do not have the driver CD (the person that I bought the mobo from didn't give me the driver CD. Can someone hlelp? thanks.

 

Also, I have a pcie card but my psu does not have the pci connector. I have the y-adapter, but my question is shoudl I connect both of the 4pin molex with the PSU? The problem is that when I connect boht, I can't boot the system. I tested 1 at a time and it seems like 1 of the molex is not working(when I connect that one along, I can't boot the system) but the other one is working fine. Would it harm my card/system if I only connect one? are we suppose to connect both of them? thanks.

Once you resolve your power supply problem try this.

 

Install the nVidia 6.70 forceware drivers. If that doesn't correct the situation, uninstall the drivers for the problem devices then let the OS re-detect them.

thanks for the reply. I had replaced the PSU and now it has the pcie adapter (though I am still curious with the Y-adapter thingy, so if anyone has any idea, I would like to hear).

 

I have solve the problem. For some odd reason, when I install the nforce4 drivers, they didn't install these drives. I have to manually update these drivers. thanks for all the helps.

I had a similar problem when installing my nforce4 drivers, I found that uninstalling the old ones with drivercleaner helped.

 

Connect all (4) the power cables to the motherboard. Also update you signature to show your new power supply

thanks for the reply. it's the weirdest thing with the nforce4 driver. Good thing that it's fixed. I am still wishing ot use the s12-380(because of the better brand and quality) but I guess for now the new hec psu would have to do.

all right. I did some carefully examination on the Y-adapter, the cabling on that looks kinda weird to me. There's 2 4pin molex on 1 end and 1 6pin molex on the other (where I connect to the vid card).

 

on 1 of the 4pin molex, this is how the cable is attached:

1-black

2-yellow

3-red

4-empty

(the numbers are according to what's on the molex)

 

while the other 4pin molex is connected as follows:

1-yellow

2-black

3-red

4-empty

 

now it looks that the order of the cables are different. If both of the molex is to draw same power from the PSU, why would the adapter's cable be different, could it be that the cabling is wrong? anyone else know anything about the adapter can shed some lights or have a Y-adapter and can check the cable's order? thanks.

Normal Molex pinout

 

1=Yellow

2=Black

3=Black

4=Red

 

Yellow - 12Volt

Black - Ground

Red - 5Volt

 

Any other configuration is non-standard and should be considered suspect.

 

You should shoot a pic and post it so we can take a look at the connectors.

here is the picture, sorry for the poor quality

I have never seen a connector like that before. If you plug that into a normal 4pin molex, you'll be connecting some normal "hot" leads to ground wires.

 

Maybe someone else will have some insight into these connectors.
