    I have a Sager NP5790 with the following specs:
    Intel(R) Core(TM)2 Duo CPU T7300 @ 2.00GHz w/4MB L2 On-die cache - 800FSB
    3070MB RAM
    Seagate Momentus Hard Drive 160 GB (7200rpm)
    GeForce Go 7950GTX
    Windows XP Pro 32-bit
    Antec Notebook Cooler

    I read an article today about CPU overclocking and they said when done correctly it can easily gives you 30-50% performance increase.
    Since I have absolutely no experience in cpu stuff (I only overclock my gpu using Riva Tuner), anyone here knows any method (which program to use or how to overclock) and if it is worth doing? Thanks. :)

    Yeah it will give you 40% increased performance if you increase the cpu clock by 40%, which I really doubt you will do. Plus, that performance increase will only be in very cpu intensive/specific benchmarks or apps. Don't expect that much increase in games or everyday tasks because those are much more reliant on gpu and memory/hd speed respectively.

    So if you're big in decoding videos and stuff like that that take advantage of a beefy cpu, then go ahead and try to OC with stuff like clockgen, or setfsb. But don't expect a 40% increase in speed.

    Plus, I bet you that the article you saw about this was for desktops, not laptops where OCing is a well known and easy thing to do.

    Thanks for the reply. Yes the article I read was talking about desktop overclocking. Although I think I would like have some performance increase for my core 2 duo 2.0 (if possible) since a few newer games seem to be quite cpu intensive. I think I would go ahead and try clockgen and setfsb to see if it really works. Thanks for the info! :) I'll report back if I have any problems (hopefully not).

    The multiplier may be locked in your proc like most C2Ds.
    If it is(most likely) then you will not be able to overclock.
    Note: overclocking will shorten your battery life, run hotter & noiser(likely)

    You're right. I just tried clockgen and the the multiplier is locked. No overclocking for me then. :( :rolleyes:

    Glad to help.
    For future reference laptops make bad overclockers because of heat issues & the whole ''battery'' idea you've heard of :D. And....Like I said most have locked multipliers.

    This thread is pretty old, however I'd hate to let this guy get away with false info. c2d's have locked multipliers = True. Only the extreme editions have unlocked multipliers. But that DOES NOT mean you can't OC them. An everyday OC wouldn't have an altered multiplier, or voltage - just a FSB increase. example: 10x FSB multiplier, 200mhz fsb = 2ghz. Set FSB to whatever you feel comfortable with, say 235... 2ghz just became 2.35. Also, OCing the CPU would result in gaming performance increase.

    Overclocking the GPU is the greater of 2 evils if you're looking for performance increase. It does result in a lot of heat increase, also it's 'real world' performance isn't there unless you're running a game that has maxed the capabilities of your gpu, then and only then would you see a gain in performance (minimal). Whereas a CPU OC would increase performance in all aspects, all the time.

    Quite true. FSB is overclocked, not CPU. Overclocking FSB "causes" overclocked CPU AND MEMORY! Just to be clear.

    So 5% FSB up gives you 5% Memory clocks up and 5% CPU clock up. In the end whole computer performance is actually MORE than 5% up (do no not add these percentages please)

    And GPU overclocking is easier, and I have seen up to 30% performance boost in games. Temp isn't the problem. OC memory on graphics card gives the best boost. Once you are happy with memory you can oc gpu core a bit.

    Add here undervolting of CPU and here you go - cooler notebook + faster graphics. That is what I like.

    Cheers,
