Beatwolf Posted June 9, 2005 Posted June 9, 2005 lol forget the above, I just had to reinstall the drivers and now it works..im too tired for this :/ Share this post Link to post Share on other sites More sharing options...
robbysca76 Posted June 10, 2005 Posted June 10, 2005 I have to have my x800xl in the second slot or windows won't recognize the card, because it won't fit all the way in the slot. When i put it in slot 2 though it does work, but when i also change the jumpers to sli mode, windows again won't recognize the card? whats wrong here? It's very strange! Try to instal newer GPU driver. Share this post Link to post Share on other sites More sharing options...
P3R3 Posted June 10, 2005 Posted June 10, 2005 So i switched my x700pro to second pci-e with NO jumper change. Have I been running 2x this whole time???!!! Share this post Link to post Share on other sites More sharing options...

You have to change jumper position to 2-3. In this mode u'll have 8x PCIx bandwich speed. Share this post Link to post Share on other sites More sharing options...

dysonlu Posted June 19, 2005 Posted June 19, 2005 The title of this thread seems to suggest this mod is only for the Ultra-D. Wouldn't it work for the SLI-DR as well? If not why? Share this post Link to post Share on other sites More sharing options...

Yes it will, its the same board but with additional futures (spelling?) I am running my 6800GT on the 8X slot becouse i have watercooling on the chipset so got no room on the upperslot. I didnt get any noticible decrease in performance. Share this post Link to post Share on other sites More sharing options...
red930 Posted June 19, 2005 Posted June 19, 2005 You can use the bottom PCIe X16 slot as a X8 slot on any of the nF4 boards.

tchuyev Posted December 30, 2005 Posted December 30, 2005 FX-WANNA-B did a great job comparing 3DMark05 scores between PCI-E2 (16X) and PCI-E4 (8X w/ SLI jumpers enabled) on the Ultra-D. But the results with the default PCI-E4 settings (2X) are still missing. This would prove if moving the jumpers around have a real influence on 3D performance. From my own experience, I haven't (yet) swapped the jumpers... but I'm losing about 300 points under 3DMark05 from PCI-E2 to PCI-E4. This is indeed not very substantial but I have that weird impression that Far Cry 1.33 is - for instance - not as smooth as it used to be on PCI-E2. And I'm sure this is not just psychlogical! As for the card I'm using, it is a Sapphire X800 GTO2 (R480) overclocked @ 560Mhz core / 600Mhz mem w/ 16 pipelines enabled & ATI Silencer 5 rev2. GPU temp. is ~61 under full load. Drivers are ATI Catalyst 5.12 without bloody CCC. Share this post Link to post Share on other sites More sharing options...
Krohling Posted December 30, 2005 Posted December 30, 2005 FX-WANNA-B did a great job comparing 3DMark05 scores between PCI-E2 (16X) and PCI-E4 (8X w/ SLI jumpers enabled) on the Ultra-D. But the results with the default PCI-E4 settings (2X) are still missing. This would prove if moving the jumpers around have a real influence on 3D performance. I've made a few tests running 3DMark05 with the VGA in slots PCIe #1 or #4 with an Ultra-D With the jumpers in single VGA mode... 7800GTX @ PCIe #1 (set to x16) =~ 8168 3DMarks 7800GTX @ PCIe #4 (set to x2) =~ 7044 3DMarks With the jumpers in SLI mode 7800GTX @PCIe #1 (set to x8) =~ 8147 3DMarks 7800GTX @PCIe #4 (set to x8) => CAN'T BOOT, VGA is not detected From x8 to x16 there is no performance influence, bellow 1% But from x8/x16 to x2 there is a performance drop around 15% I haven't tested "real world games", I think less 1000 3DMarks can mean something. CPU tested was an A64 3000+ @2.43GHz with 4x512MB RAM (2GB) running @DDR405 CAS 2.5-3-3-7 command rate 2T, using 150MHz divider Share this post Link to post Share on other sites More sharing options...
