xynder Posted June 1, 2006 Posted June 1, 2006 When I am looking at my video card properties, for some reason it reports the bus as PCI-Express x2... shouldn't it say PCI-Express x16? I have a DFI Lanparty Ultra-D (non-SLI) and an XFX GF7900GT. Share this post Link to post Share on other sites More sharing options...
Thraxz Posted June 1, 2006 Posted June 1, 2006 Put the card in the correct slot next time. Share this post Link to post Share on other sites More sharing options...
red930 Posted June 1, 2006 Posted June 1, 2006 The top PCI-E slot is 16x and the bottom (underneath the chipset) is set at 2x. If you switch the SLI jumpers on the motherboard both PCI-E slots will become 8x. If you're worried about your chipset cooler not getting enough air flow move the SLI jumpers on the motherboard so that bottom PCI-E slot goes from 2x to 8x. They've said 8X is not that much different then 16x. So when you do finish doing these suggestions run some benchmarks and see. Good Luck!

red930 Posted June 1, 2006 Posted June 1, 2006 They've said 8X is not that much different then 16x. It isn't different at all, done the tests myself. Share this post Link to post Share on other sites More sharing options...
Thraxz Posted June 1, 2006 Posted June 1, 2006 It isn't different at all, done the tests myself. Did you try different resolutions by chance? I'm told that high resolutions requires the bandwidth. Share this post Link to post Share on other sites More sharing options...

Also, since he has a non-SLI MoBo wouldn't he have a problem with SLI jumpers? (I'm totally unfamiliar with that aspect of Ultra-D boards) Share this post Link to post Share on other sites More sharing options...
red930 Posted June 1, 2006 Posted June 1, 2006 It isn't different at all, done the tests myself. Yeah, i remember someone doing some benchmarks regarding that. Where is the link and just like the person above has mentioned, which resolutions did you test the games? Share this post Link to post Share on other sites More sharing options...

I'm told that high resolutions requires the bandwidth. http://www.dfi-street.com/forum/showpost.p...803&postcount=2 Nope, just left it at standard tests so people could see 'relevent' numbers to compare them directly to their own. However I am running on x8 right now with no reduced performance as far as I can tell, breaks 11k easily in '05. Also tried some bandwidth test that NeoAethyr gave me, but I don't think it worked properly as numbers were all kinds of messed up. The main point I saw was only a 20% decrease in performance even at x2 speeds, so obviously x8 should be more than enough. Share this post Link to post Share on other sites More sharing options...
Thraxz Posted June 1, 2006 Posted June 1, 2006 Looks good. I only take issue with the use of 3dmark as a 20% drop in performance when a good portion of it is based off of the PCU speed. Assuming that the video card is responsible for 50% of the score that corresponds to a 40% drop in video card performance. While that still means that 8x shouldn't have a problem it's a nit I want to pick. Share this post Link to post Share on other sites More sharing options...
xynder Posted June 1, 2006 Posted June 1, 2006 I am looking through the Ultra-D manual, and all it says is that both slots are PCI-E x16. I don't see anything about jumper settings. Share this post Link to post Share on other sites More sharing options...
cuoficr Posted June 1, 2006 Posted June 1, 2006 If you arent going to do the suggestions why bother asking for help? the jumpers are staring u right in the face if u r looking at your card in the bottom slot, and no they arent both x16 Share this post Link to post Share on other sites More sharing options...

I said I looked thru the manual and didn't see anything about jumpers... I can't just randomly change jumpers! Share this post Link to post Share on other sites More sharing options...
