Hey all, I'm in the middle of building my system and have hit something outside my knowledge. On my mobo (DFI Lanparty nf4 SLi DR) there are two power connectors (a 4-Pin HDD type and a 4-Pin FDD type) as well as the 20-Pin and 4-Pin ATX supply sockets. The manual just labels them as: "2 4-pin 5V/12V power connectos (HDD and FDD type)" with no explanation as to what they are for. They are female connectors so I am wondering if I am supposed to plug in connectorfs from my PSU, for extra power or summat, but I don't wanna fry the board if they are just extra outlets. Can anyone tell me what they are for?? Thanks, tetra.
Its alright, I found an answer through google. Took a while though. Thanks anyway.
And for the sake of evertone else here, you found that: -The large 4-pin molex provides auxiliary power when running two video cards, and -The small floppy-style connector gives the DIMM slots access to the +5V rail for running Vdimm above +3.3. Am I right?
Precisely. The only addition, which is mainly logic anyway, is that running without the aux. power supplies causes a lot of instability.
I finished the system, only now when I enter the BIOS to configure everything the system hangs after about 10 seconds within the BIOS. In that time I have checked the temperatures and they are all comfortable (CPU at 40 oc e.t.c). My specs are: DFI Lanparty nF4 SLi DR AMD FX-55 Leadtek 7800GTX TDH w/ MyVIVO OCZ 1Gb DDR PC5500 Dual Channel Memory Thermaltake PurePower 680W PSU (Triple Rail) WD 200Gb SA2 HDD LiteOn CDRW/DVD-ROM Samsung 15" LCD Panel Gigabyte G-Power Pro CPU Cooler Thermaltake Kandalf Steel Case The onboard LEDs show (in order) System Startup, CPU Detected, DRAM detected and VGA detected. Can anyone shed any light on this, I really want this system up and running. Thanks again.
