    So, I have a T9600 at 2.80 GHz in the laptop in my sig right now, and I've tried overclocking it, but it is only stable up to 3.1 GHz. At 3.15 GHz, it crashes after about 3 minutes of Orthos, or ~2-5 hours of SETI@Home. I know the instablity is not caused by RAM because my P7350 used to be stable at a higher FSB.

    I've left it at 2.80 GHz at 1.200V (from 1.263V stock) just so it runs cooler. the 300 MHz clock speed increase isn't worth the power/temp increase at load (37W, 67C -> 41W, 70C), especially since I can't undervolt when at 3.1 GHz.

    Now, I was hoping for at least 3.3 GHz from this CPU, and I am disappoint...
    Is there any use in upgrading to a T9900 from this CPU? It will cost me an extra $100 if I sell this one after buying the T9900.

    Also, if there's anyone out there with an overclockable T9900, what clock speed can you go to? Since it's the highest-end Core 2 Duo available, I'm guessing it's the highest binned, and will probably overclock quite well.

    EDIT: I was also considering the X9100, but those have a higher TDP and the Asus G51VX BIOS doesn't allow multiplier changes, amirite?

    If you want a processor taht OCs well, get the Core 2 Extreme, such as X9000.

    So an X9100 will in general clock faster than a T9900 even if I can't change the multiplier in my BIOS (that is, just changing the FSB)? Your X9100 link links to the T9900 again, so I don't know whether the multiplier was changed or not.

    Ok, X9100 @4ghz:
    http://valid.canardpc.com/show_oc.php?id=551676

    EDIT: looks like you will reach 4ghz + without overclocking the multi.

    But it's down to luck. The X9100 CPUs are very highly binned. So you're getting the best of the best.
    Still you have to have some luck.

    Hmm, I wonder how legitimate that is. I mean, my T9600 clocks to 3.3 GHz (I didn't dare go higher), but as soon as I run something intensive (BOINC or Orthos), it will blue screen. So I could submit a 3.3 GHz CPU-Z Validator result as well.

    I was wondering if anyone here on NBR has had success overclocking their T9900 or X9100 to over 3.5 GHz and being stable for an extended time in Orthos. I would greatly prefer the T9900 because of the lower TDP, but if the X9100 is much better, my computer better get used to running hot...

    I'm sure that people just overclock as much as they can, keeping it stable enough to save the validation. That's how I do it.

    I agree that 4ghz would have not been stable. But I do believe that it would be stable over 3.5ghz.
