Problems problems
I've just built a new nachine as follows:
Gigabyte GA-K8NXP-SLI board Gigabyte GV-3DI card (the twin 6600GT gpu that came with the board as a bundle). 1 gig elixir ram 120 Maxtor Hard drive Colorsit 550Watt PSU AMD Athlon64 3.2 Skt 939 Softwa WinXP SP2 and all updates DirectX 9.0c 3Dmark05 and Joint Ops (a game that came with the card) No other progs installed at the moment. Problem - The graphics are AWFUL! Using the included drivers 3Dmark gave a score of 5906 BUT in the second part of the test the screen was just totally scrambled Joint Ops runs but there are parrallel lines down the left hand side of the screen and a single line horizontlally in the middle of the screen. Where they cross is a solid rectanglular block of colour. Green if it matters Screen set at 1024x768 x 60Mhz Exactly the same results occur with the Nvidia beta 77.76 drivers. There is a 'tweak' programme on the driver disk but any changes made with it from default make things worse as does using any of the preset Nvidia game settings. What am I missing? Many thanks - Jb |

Those lines show how the screen is divided up for SLI load-balancing between
the two chips. It's a debug/demonstration feature that probably got turned on by accident. There should be a checkbox in the driver panels (where you can also select between split-frame rendering or alternative-frame rendering). -- "War is the continuation of politics by other means.

Many thanks for the speedy replies and in response to doctor.ratt I have Xp
Pro not the home version. First of One, much respect, you hit the nail on the head. In the SLI configuration panel I had turned the 'Show load balancing' option ticked. Unticked it and the game plays fine. In 3Dmark however I now find the score to be a max of 3513 Test1 - Highest FPR 24 Ave - 15 Test2 - 23 8 3 21 12 4 2 1 5 5 3 But all scenes are clear and viewable Any thoughts on why such a low score? Thanks Jb |

I'm surprised you didn't read about all the SLI "features" before spending so much money on such a combo. :-) In 3Dmark however I now find the score to be a max of 3513 Test1 - Highest FPR 24 Ave - 15 Test2 - 23 8 3 21 12 4 2 1 5 5 3 You might want to toggle between split-frame rendering and alternate-frame rendering and see which one gives you better results. Make sure your 3DMark app is patched to the latest version, too. nVidia's SLI implementation isn't as robust as 3dfx's from the old days. -- "War is the continuation of politics by other means.

Oh I read about SLI till it made my teeth itch That was partly the
problem! When I researched SLI I found this: http://www.guru3d.com/article/Videocards/185/3/ and set it as per the picture. I suspect you may be right, again, but the setting 'Alternate Frame rendering and Split frame renedreing are not there? Not greyed out unusable, not there at all. I am now using the latest drivers from Nvidia and 3d mark is a fresh download. I tried Nvidias game settings which brought me to a new quirk. The Global settings has disappeared and my only option is to modify one of the existing pre-sets. I'm a recent convert to higher end cards and CPUs so messing around is not something I'm really comfortable with at the moment. Steep learning curve or what! Thanks Jb |
