    what is the deal?????????? it would seem that the 256mb card is better??? is this really the case?

    i got smoked by a 256mb 8600m gs. and i also noticed that the clocks on the 256 are considerably higher.

    hummmm

    any thoughts on this would be welcomed

    The clocks are weird for both systems.

    Stock - 600 Core / 700 Memory
    256 Mb - 680/750 understandable slight overclock.
    512 Mb (Yours) - 675/450 ??? Huge memory downclock.

    I don't get it. :confused:

    If those are your "stock clocks" then it must be a very crippled version of the 8600M GS. 500/400 is quite far from the standard 8600M GS, which is clocked at 600/700. Does the GS have a DDR2 version?

    so no one else has the same memory and shader clock?

    geforce 512mb (dedicated & not shared) 8600m gs 500/400/100 = gpu/memory/shader

    nvidia has it at 600/700/1200 = gpu/memory/shader or so they say, but no real definite answer anywhere. this would seem to be for the 256 + 256 shared memory version of this card

    geforce 512mb 8600m gs 500/400/100
    what is the next step?
    Why a downcloked card?
    I'm puzzled too..

    hummmm...makes perfect sense.......but ummm....I DONT LIKE IT! *LOL*

    Memory doesn't matter for the card anyway. 512 Mb is overkill for the 8600m GS, underclocked or not.

    I talk to a HP tech supervisor and they said they underclock the
    card with their driver.... and it's in specs they said..
    by the way the gpu-z read on mine is 0 and mem 0 now and crash..
    and n-tune report nothing for clocks..!?
    wierd.

    you'll probabaly have to reinstall the driver then.

    and i figured as much. (hp underclocking) they should have at least left the card the same as the 256mb version.

    I'm in the same boat as well.

    I have a DV9500CTO with the 512 8600M GS and according to nTune from
    nVidia, I have the same 500/400 numbers. I am going to try a driver from
    http://www.laptopvideo2go.com/drivers to see if I can improve things.

    nTune sucks.

    It dangles a carrot that you can't bite.
    While it looks like you can overclock, that is a joke because the
    settings always revert back. I used it only to get the clock numbers.

    vista ntune is like for beginners and rivatuner is the advanced version for vista.

    apparently you get more things to do in the xp version of ntune. gonna have to check that out.

    Well, 169.04 wasn't any good if the blue screen of death is any indication.

    I haven't seen that screen since Windows 98.

    Good thing I have a backup DV6500 and that I haven't mirrored my oc
    efforts on that one yet.

    I'll try safemode to recover my DV9500....

    I'll then try that other driver version.

    Once I have one working, will RivaTuner work??

    So far it hasn't with stock HP drivers.

    I made it a point to click on the left side of the page for Vista 64 bit.

    My downloaded file is confirmed to be Vista 64 bit.

    Since I am not sure if my blue screen was the driver or the result
    of installing Riva Tuner or nTune, I'm going to restore the system
    using Acronis and start over from a point before all of this OC interest.

    ah yes, acronis is my next best friend..lol

    and it's not rivatuner or nvidia...unless you overclocked to high.

    the highest i could get out of it was 675/460/1500

    The funny thing is I haven't oc'd anything yet.

    I am still trying to secure a reliable means of doing so, hence my install
    of RivaTuner but all of the options were greyed out, save the advanced
    menue that I was not going into.

    So it must have been the driver version of 169.04

    I am back in Windows, with 169.04, I'll try a series of reboots
    to see if it blue screens again.

    Well, I rebooted a number of times with driver 169.04 and no problems.
    I try to run RivaTuner and I get a "digital driver" warning. I let RivaTuner
    try to disable digital driver signing and reboot. My blue screen is back.
    Now that I recall, this happened before the first blue screen. I restart
    and Vista loads normal, once in Windows it informs me that Vista has recovered from an error. I try to run RivaTuner and again, can not load
    Riva Tuner 64.sys driver and would I like Riva Tuner to disable driver signing.

    Conclusion: Riva Tuner isn't 64 bit compatible despite its claim to be.

    Does anyone have a utility or method to oc the 8600M GS that is 64 bit
    friendly??

    I ran 3DMark06 as the trial version. As it was testing, the FPS at the bottom
    read off 3. I doubt I only have 3 frames per second. Thats why I want to try another one.

    I take it back.

    I ran F.E.A.R. and had the game complete its own internal test.

    My Minimum FPS 2
    My Maximum FPS is 13

    What the hell is wrong???

    nah. means you have to reboot your computer to reload the video driver. at least, that's what i have found out. then it works like it's suppose to.
    you should at least be getting 12 frames or higher in the first 15 seconds
