jippen Posted May 23, 2005 Posted May 23, 2005 Hello, i just bougt a nf4 ultra-d and a HIS x800xl graphics card. when i try to install the graphics card in the first pci-X slot it doesn't fit into the slot because the fan of the nb is in ists way(on the x800xl is a large cooling fan on it) so i put it into the second pci-x slot and everything works. now my question. if i put it in the second slot wil it work at x16 speed ? (bandwith) in single vga mode ? the manual says single vga mode: 1 pci exprss graphics card on the pcie I slot will run at x16 bandwith the other x16 (pcie4) will run at x2) but i don't understand it good. will the second pci-x slot run at x2 if a graka is inserted in slot 1, and is this the other way around also? is my card running at x16 in slot 2 ? (nothing is inserted in slot 1) if not,is it possible to change with the jumpers ? i hope you understand what i mean. thanks in advance Dimitri Share this post Link to post Share on other sites More sharing options...
pgamble Posted May 23, 2005 Posted May 23, 2005 Nope .... I think you need to set the jumpers for SLI .... The second slot will then operate at 8x. This should not give any performance impact though as these cards wouldn't saturate the throughput. Paul. Share this post Link to post Share on other sites More sharing options...
jippen Posted May 23, 2005 Posted May 23, 2005 so the info from dfi is not correct (there are no 2 x16 slots !!!!!!!!!) at page 67 in the manual it says 2 x16 speed pci slots.... furher it says in sli 2 times x8 speed. and in single vga mode slot 1 at x16 and slot 2 at x2. is it possible to run slot PCIE4 at x16 and slot PCIE1 at x2 speeds ? if not, why it says that there are two x16 slots...... gr Dimitri Share this post Link to post Share on other sites More sharing options...
Sharp Posted May 23, 2005 Posted May 23, 2005 Hello, It says in the manual that there are 2 PCIe x16 slots on the board. If you count how many x16 slots, how many can you see? 2? keywords "2 x16 slots" The manual is referring to the physical size of the slots, not the bandwidth.

jippen Posted May 23, 2005 Posted May 23, 2005 so if i run my graphics card in the second slot it wil run at x16 speed , right ? and if 2 cards are inserted two times x8.right ? Share this post Link to post Share on other sites More sharing options...
Sharp Posted May 23, 2005 Posted May 23, 2005 Nope, If you put a gfx card in the second slot it will run at x8 providing you move the SLi jumpers. By moving the SLi jumper you will make both slots run at x8. The second slot = x8 max Share this post Link to post Share on other sites More sharing options...
crazybones Posted May 23, 2005 Posted May 23, 2005 Jippen, I've just built a system with the same motherboard and graphics card - please see the thread: http://www.dfi-street.com/forum/showthread...2&highlight=fan As you will see, provided you move the SLI jumpers, there is hardly any performance hit in 3DMark05, by using the second slot.

Radical_53 Posted May 23, 2005 Posted May 23, 2005 On the Ultra you will have to perform a SLI-mod to get the lower slot working 8x. Share this post Link to post Share on other sites More sharing options...
exscape Posted May 23, 2005 Posted May 23, 2005 On the Ultra you will have to perform a SLI-mod to get the lower slot working 8x. No you don't, you just have to move the jumpers. Share this post Link to post Share on other sites More sharing options...
Radical_53 Posted May 23, 2005 Posted May 23, 2005 Are you sure about that? I did the mod just because I wanted to put the card into the lower slot. Share this post Link to post Share on other sites More sharing options...
jippen Posted May 23, 2005 Posted May 23, 2005 is it possible to move the jumpers by hand ? because there is no chip puller provided. Share this post Link to post Share on other sites More sharing options...
exscape Posted May 23, 2005 Posted May 23, 2005 Radical_53: Well I didn't move any jumpers and I got 2 x8 slots EDIT: Got it all wrong above! Of course I moved the jumpers! What I meant to say was, I didn't mod the chipset. jippen: Yes, it's possible. Just be careful (if that's even necessary ) and you'll be fine.
