    After a short benching, it keeps getting problems dropping back to desktop after a bench
    PSU problems ?

    Excellent start w/ 6800U + cascade Sir!


    Interesting to see how 'different' the cards are but still score basically the same overall result.
    Seems that NV40 has more 'raw speed' (GT1-3) while the X800XT has better shader powa (GT4)?

    GT: 6800u: x800xt:
    1_: 438.3 414.6
    2_: 126.1 122.1
    3_: 107.9 101.4
    4_: 97.9 115.8
    tot 16734 16802

    Lets include coolaler's 16383 result here too:

    its at 590/1250. Quite a bit higher nature result and also a bit higher GT2 and 3. Is the NV40 all memspeed limited at those GPU speeds?

    Nice score Lardarse

    Do you get better overclock results if you can supply more than 12v through the twin molex connectors, or is the 1.67v to the gpu causing the limit only ?

    That GT4 result replicates other ( lower ) 6800 scores I have seen, ie it is a lot lower than ATi. As GT2 and GT3 use shaders but GT4 is the only DX9 game then I guess either the DX9 shaders are different or nvidia DX9 is not so hot at present full stop.

    I guess nvidia driver time will be working on this over the following weeks ( hopefully their halo's will not slip ) and if they can match Ati there then this is looking very good.

    It would be nice to find a software or hardware fix to stop the nvidia series defaulting back to 2D speeds when pushed too far, this nannying, for non extreme overclockers, is annoying.

    Regards

    Andy

    PS Sorry for the long post, have you done any 2001 benching yet ?

    I dunno it could be that throttling does come in some time, throttling back the memory speed. The only recent nvidia card I played with was the 5600 and it seems to behave the same way, you can easily tell when throttling comes in with core being pushed too far (a long jerk) but when the memory throttles, you can't tell except from the fps.
    Berkut don't think so, it will keep going on 3D but coming back to desktop gives black screen.
    No 2001 yet, but I expect it to be significantly worse than ATI as per nvidia's trend.
    My 12v is around 12.2v underload with the EE sucking 1.85v.
    I'm gonna try rivatuner to see if i can adjust some LODs. Will be trilinear optimizations be faster or should I just turn it off?

    Leave the optimisations in as that will force brilinear rather than trilinear so make it faster.

    For LOD expect GT1 to go down but GT2,GT3 and GT4 to go up in fps, well it did with the FX series, but you may be capped by the P4 in GT1 so having the LOD high here might not effect it.

    Try LOD of 3,6,9 and 12. My guess is a LOD of about 8 will be best.

    Any chance of running the same cpu clock as macci and showing a screen shot?

    Still hard to imagine that just a month or two ago, you guys were struggling to get 10k. Considering that a X800XT or 6800U would give me about 2.5-3 times what I have now... it might just be time to kick the bucket, suck it up and smack down the cash on the barrell head, and get either X800XT or 6800U.

    16-17K is is ridiculously high... A year ago before Radeon 9700pro, I was struggling to get 5K. (which means: great job man at an amazing overclock)

    Lardarse, or macci:

    Do any other game tests start to show gains from fast CPU other than GT1 yet?

    6800 and 6800U scores can now be published on the ORB.

    At present there is one entry !

    Lardarse, publish your score !

    Regards

    Done:

    Its no WHQLed though, I'll need to rerun with 60.85... if I can solve the stupid throttling nonsense

    install with high GPU/ram temps?

    All along the watchtower the watchmen watch the eternal return.

    Heh I wonder if Computex Taiwan had anything to do with it? I was messaging over the phone to Visionary who's over at Taiwan now about coaxing out the secret to disabling thermal thrttling out from nvidia. He said nvidia personal admitted that there is a too hot and too cold limit that throttling will set in. And he said he would try to talk to Futuremark to get them to allow the publishing of 6800 scores.

    What is that throtling thing???

    Nice scores... But i think that 3dmark should be benched at 1280x1024 with 8AA/8AF... Otherwise it just sux... Your not even stressing the card :o/

    the 6800 has a "too cold" limit? nvidia

    17K breached!



    http://service.futuremark.com/compare?2k3=2603430

    603/1250

    I've had to alternate between drivers/powerstrip, etc with warm GPU until the throttling seems to go away. Now I'm just a little wary of installing the 60.85 drivers for fear of it coming back!!

    Anyways, 608/1270 should be doable...

    Shamino: are the 60.85's faster? Or did you mean the FM-legit 60.72's?

    If I'm not wrong 60.85 should be the latest WHQLed, but I heard that 61.11 is faster, which is what I'm using now.

    So youre going for FM approved or merely WHQL status?

    I don't think it should matter much, as the 61.11's appear to show natural D3D speed increases rather than FX-style hacks to gain speed.

    People should figure out that your 17K is more than legit.

    Nice score!
    Good luck to the next barrier! (18k)

    Darn... We are actually kinda close to 20k... I dont think that 3dmark01 should survive the next generation of gfx and cpu... That would be just lame...

    Just reran with 60.85 drivers with 600/1250: 17117

    http://service.futuremark.com/compare?2k3=2603719

    FM is really coming down on nvidia hard huh, it won't even approve the 60.85 WHQLed drivers...
