    WoW!! I found this on youtube! The GTS 250m with 1GB GDDR5 (clocked up to factory Nvidia specs) did 10,691 in 3DMark06.. That is GTX 260m territory! And i'm sure the GTS 250 w/GDDR5 has more left in it once better drivers hit. :)

    *Has anyone here got any higher yet?

    It is a hell of an overclockable setup. I have tested some, however a nice, word of warning to folks...

    It's a laptop with LIMITED cooling capabilities. I would highly suggest to either NOT overclock or do not go more than 10-15% over rated speeds.

    I say 15% max because much higher and the temp DID start rising. :)

    Also I wouldn't recommend overclocking the 250M since its probably a rebranded faulty GPU that goes bad real quick once forced to draw more power that leads to greater heat that leads to the chip basically frying, thats why Toshiba prolly underclocked it.

    Thats also why prolly the same reason why my BB Asus G72's 260M is underclocked.

    heh heh heh

    Yeah - I could totally see the machine going up in a ball of flame. :D

    Toshiba's are not generally known for their cooling skill....

    Still - it IS an impressive result for overclocking.

    http://www.theinquirer.net/inquirer/news/1004378/why-nvidia-chips-defective 3 part article

    Here read up

    It goes officially up to the G86s but since most of the 200 series is just rebranded 9 series cards made in lower with a lower fab and in some cases just rebranded. I suspect the card being made in a lower fab might have mitigated the problem but if these cards are pushed harder than manufacture intended, I wouldn't be surprised if people are going to get card failures.

    I don't think the problem will be solved until maybe the release of Fermi

    Learn a little more about NVidia chip platforms before you make ridiculous posts.

    260M is G92b architecture based, while 250M and below are completely new architecture (GT2xx with Direct3D 10.1 support). Even G92b was not affected with G86 problems, you are trying to connect completely unrelated things.

    I've been running my 250M at frequencies returned to stock (500) for 1.5 months now completely without thermal problems.

    BTW since modern NVidia cards all have hardware throttling, it's not possible to thermally damage them. They will automatically throttle down when temperature goes above safety threshold. So please, dont bother scaring people with these old fashioned tales of overclocking making your GPU/CPU burst in flames.

    I think main reason Toshiba reduced clock on 250M is not the thermal constraints, but power constraints. With clock returned to stock it's defenitely possible to push wattage envelope above meager 120W that stock power brick provides. Haven't noticed any adverse effects yet, but may be on the long run.

    Okay you have fun in Reality Distortion Field emitting from your Toshiba :D

    1.5months is nothing. Get back to me in a year and tell me your GPU isn't dead.

    Toshiba runs their GPU lower than stock so they can get the energy star ECOGREEN rating. The GPU is still rated to run at NVIDIA stock speed and does so very well.

    Another thing to keep in mind is Toshiba also went with a lower wattage power supply for the green rating. If you overclock too much and make the card draw more power, you may also push your power supply beyond what it's rated for.

    Again, Toshiba is UNDERCLOCKING from the Nvidia rated speed. "overclocking" it back to it's manufacturer rated spec should cause NO damage to the GPU itself.

    That doesn't mean you may not have heat related issues or abuse your laptop's power supply.

    are you really that difficult ?

    G92 arch. did not have failure issues

    Not to mention that 250M is not G92 even, its next generation. So *maybe* it will have own issues, but these issues will be completely new ;)

    Giving that fact that I've never seen temps go over 70, I most likely will :)
    Power brick - well, maybe, but not so expensive to replace, and even with more powerful one.
