It's okay in the 2nd slot as long as you move all the sli jumpers down to the bottom, this will make both slots use 8 PCIe lanes each.

NCC · 30 Jun 2005 at 18:47

Sli jumpers?

Ah got it, yeh they are already on 1-2 which is single VGA

ps3ud0 · 30 Jun 2005 at 19:39

Hmmm thats a good question - if I leave the jumpers in normal VGA mode and place my GFX in the second slot will it run as a 16x lane or a 2x lane? I have to admit I totally forgot about this and have the feeling Ive been running my X850XT PE on the 2x lane - assumed it did some sort of auto-switching or something...

Hmm when I get it working Ill swop it over...

ps3ud0 :cool:

Need help VERY quick here, as im in the middle of putting my system together with this board.

Whats the power connector for thats by the fan/nf4 chipset on the board? It's like a power connector that CD/DVD drives have... should i connect to it?

Or are the main 24pin power connector and the 4 pin one all i have to bother with?
Please help QUICK! cheers...

NCC · 30 Jun 2005 at 20:34

You would have to plug in the 24 pin connector and the square 4 pin connector too. The other moxel connector is just a spare for a HDD or an optical drive.

Hope that helped.

Guys,

Do I need a floppy disk drive just to get a single SATA HDD working?

MR.B · 30 Jun 2005 at 20:50

Thanks for the help

So just the 24 pin connector and the square 4 pin connector then? as with any other board.

The molex connector on the board confused me lol. never seen one on a board before

NCC · 30 Jun 2005 at 20:51

Yes, use the 24 pin connector and the square 4 pin.

There should be another cable in the box which connects that molex socket to a hard drive, optical drive etc.

Saftlad · 30 Jun 2005 at 21:01

You should connect all 4 power cables to the board,
24 pin
4pin p4
4pin molex
4pin floppy type.

you don't need a floppy unless your using raid

MR.B · 30 Jun 2005 at 21:30

Ohh now your've gone and ruined it! lol
Ok... why would i want to connect a molex from my POWER SUPPLY to the motherboard??

smids · 30 Jun 2005 at 21:35

Because it helps with stability. It supplies extra power to the PCI-e lane to avoid graphics stability issues - mainly for use with SLi but certainly does help all round. The floppy connector helps regulate the motherboard IIRC.

MR.B · 30 Jun 2005 at 21:41

Oh right... 4 power cables connected then.. thats a lot. I have two molex connectors on my OCZ power supply just for graphics cards... there more than capable of running my 7800 so should i bother with the molex on the board being as i dont plan using SLI any time soon?

On DFI street board this is a direct quote from a DFI emplyee ( DFI doesn't put connectors on the motherboard for fun)

Please take that as it is intended it is not something I'm saying or trying to be clever, it is a direct response to another owner with similar problems who hadn't connected all of them.

If you left the jumpers in single card mode then yes the 2nd PCIe graphics slot is only running at 2x.

smids · 30 Jun 2005 at 21:54

You have to connect them all. If you don't and ask for help over there, they will not help you until all are connected. A bit harsh, yes, but they are DFI technicians so need to find the real cause of all problems rather than allowing for a margin of user error.

MR.B · 30 Jun 2005 at 21:55

I'll connect all four power cables then... even though its making my case very messy with wires.
Anyone want benches for the 7800GTX when i get it all running?

How would I get the second pcie slot to run at full speed?

I cant install the graphics card in pcie 1 because the southbridge fan is in the way.

Broken Hope · 30 Jun 2005 at 22:26

Single drive requires no drivers so nope you won't need a floppy.

MR.B · 30 Jun 2005 at 22:36

I've seen benchmarks before with the PCI-E set to 2x and there is hardly any differenct between that and 16x, as 2x PCI-E is still a lot faster than 2x AGP for instance. It was something like 5% slower with 2x on PCI-E.

And IF you mean the mobo fan is getting covered by the graphics card then i wouldnt worry coz all my graphics cards have done that and its all worked fine for me...
