    Default Unlocking shaders

    I'm running, if you haven't seen me post it before, a Leadteck 6800LE. For the price I'm really happy with it. A lot of games run almost flawlessly with all 16 pipelines open. The problem I'm coming across is getting the vertex shaders. I have no problem unlocking them it's just when I run 3dmark and some newer games they'll freeze up and my comp will crash and restart. Now I have shaders 0, 1, 2, 3, and 5 open and 6 closed. So far it seems that it's the only set up that isn't screwing up. I have had all 6 open and running fine but it seems when I change the order of using 5 of them, say the next day I try and use shaders 0, 2, 3, 4, and 5 it will be verry unstable. Why is this? I know it isn't a heat related issue because under load I only peak around 46 C. My clocks are 350/800.

    The PC is an Epox EP-9NDA3J Nforce3 Ultra

    That was happening to me for awhile to, then i found out it was a cpu issue for me that is. I read taht nvidia uses a test all the gpus, those who pass the clock speeds and are in great stable condition become ultras and gts and the rest become the low end gpus. I am pretty sure you vertex shader is bad even though they work. But comon now, you manage to unlock all the pipelines and vertex but one is unstable so you might ass well disable it. I got all the vertex but my last pipeline is messed up .. why are you trying a different order? why dont you just leave 0 1 2 3 5 open and leave 6 close if it works.

    Yeah, I just was wondering if someone else was having those problems too. I'm completely satisfied with what I got I just wasn't sure why some of the vertex shaders were not as stable. But you're definately right about the tests that the gpus go through, I just remembered that part and that's why. I leave mine at 12x6 because I get no artifacts at that and very little heat. Very awesome card though. I'm extrememly pleased.

    EDIT: I leave mine at 12x5

    Why don't you leave it at 16x5? mine is 12x6 and stable after hours of playing around with it.

    Well, I've been playing at 12x6 lately and I've been noticing decreasing performance. I'm going to set it to default speeds and all and see what happens. My ATI card is performing much better so I'm just going to use it for gaming right now and put the 6800 in my other computer and run lots of tests on it.

    Hey everyone, I just decided to save space space so I'm re-using my old post here. I'm debating on whether to go with the Nvidia 78.xx driver or the Omega 1.6693 (66.93 Forceware). I'm going to be putting the card under a lot of stress and in a not so cool environment, which I plan to be adding a bit more really soon. I just want to know which drivers you think are better for overclocking. I would assume the newest Nvidia ones, but we all know that assuming makes and ass out of u n me! Anyways... I'm also posting in overclock.net and planetamd64. I've noticed a few people in here know a whole lot about Nvidia, specifially Yawg, so I would just like to know how I can beat the crap out of the 6800 with the best results. I'll be using RivaTuner.

    So...Omega or Nvidia Forceware?

    P.S to AsianBatman, I unlocked all the pipelines to 16, but now when I reset everything to default it sets it to 8 pipelines :( I'm hoping I can just erase the reg files associated with the drivers and clear everything so when I put the card back in it registers as 12 default.

    Haven't played around with Omega's for nVidia, but my experience with them and ATI cards is good. I really doubt it'll do any better as far as temperatures go, but you can always give it to go to see if gives any performance improvement or any other benefit.

    I dont know, i had bad experrience with omega drivers in the pass, didn't really see a huge gain enough to stay with them. It seems my 16th pipeline is damage, so can't really do anything about it. I recently read a article on a benchmark group who just discovered taht nvidia checked on the benchmarks AGAIN!! They found out that on benchmarks that use AF/AA, nvidia has programed the 6xxx and 7xxx to use low quality AA/AF. When the benchmark group reprogramed the drivers to use normal quality AA/AF like Ati cards, the scores of nvidia cards took a 30% hit. Just thought you guys want to know ^_^.

    The omega drivers for nVidia suck, big time. I got much better results, and higher overclock with forceware. Now as for my ATI card, I use NGO optimized drivers. WOW. They are optimized for 256MB cards and there's a huge performance difference from the basic Catalyst drivers to these. My bottlenecking has decreased by a good 30% if not more. Although when I overclock the card seems to not dissipate the heat very well so I ordered a new cooler (when there was no porn :( ) and that will help a lot. But man, those NGO drivers rocked my card so much. It was unbelievable to see that kind of increase in performance. I'm going to run 3dmark and aquamark soon and I'll post my results. Catalyst and then NGO optimized.
