    Default 7805u - X9100 vs T9800 vs T9900

    X9100 - 3.06

    T9800 - 2.93

    T9900 - 3.06

    I heard that the mobo max is 3.0 ghz- Anyone here running their X9100 or T9900 on a 7805u without underclocking the cpu?

    Thanks!

    It's not like the .06 ghz would make any performance increase at all.

    the t9900 is better it consumes 35 watt compared to 45 watts which will allow for a cooler cpu and less power consumption. also, since you won't be able to overclock, an extreme edition cpu is not needed and is just going to be more expensive. otherwise, if a t9800 is cheaper, check that out.

    I know. But the prices on ebay are so close to each other (except for the T9900, which is more expensive), I'm just wondering why would anyone get an X9100 for their 7805u when it cannot be overclocked for this model (yet). Also, the fact the mobo would only support up to 3.0 ghz, wouldn't you have to underclock the X9100 (or T9900).

    edit: I take that back. Right now, T9600 (2.8 ghz) is the best bang for the buck at $217-

    Why would the mobo cap the CPU speed? Doesn't make sense to me... although if you have the money to upgrade CPU, do you really need it? If you max out your CPU for calculations or graphics work then get the X9100, you can undervolt it easily. List out all your CPU options w/ prices and what your usage is.

    None of them are worth $200 over the T9600, so I'd take that one.

    Since we are talking cpu's, has any one gotten a Quad Core to work on this Lappy? The new p-7808 has a Quad and all internals are the same. Sooo, I went and bought a q9300 Quad core and my system won't boot with it.Why won't it work. Put the T9600 back in and it's fine.

    Here ya go-

    I should mentioned that in the 7805u, this functionality is currently locked- or is it no longer?

    What's the version of your BIOS? From what I understand, the heatsink needs to be upgraded as well to cover both cpus-

    edit: Hey, thanks for confirming that even with the 9C.17.00 version of the BIOS, quad core still won't work-

    This is true about the heat sink. I don't think thats why it's not POSTing though. It will power on but thats it. No POST. Nothing on display. And only about an 8th of an inch of the cores isn't touching the sink. Man I hope someone figures this out or I shelled some big bucks for nothing. Crap....
