    So earlier on (bout 2 weeks ago) i was trying to figure out the type of MB i have in order to OC my laptop, well now i found the type of MB i have and i can OC, what seems to be my problem is i cannot OC over 1836.6mhz, my laptops original clock is 1.6ghz... so its not too much of an upgrade... After trying to increase it past 1836.6, for some unknown reason it decreases back down to 1400's. Oh BTW I am using SETFSB to OC. Thanks for your helpzy :D

    Enjoy your system instability and cooling problems. Have you considered that the PLL does not able to set above this level?

    As I stated in your other thread, I think your Clock Generator is slg8sp626v, and as your using SLG8LP625T, I'd say the trouble you are having is SetFSB needs to be Updated for the slg8sp626v.

    It's a can of worms, first SetFSB Source Code is in Japanese, next SLG does not Offer a Data Sheet for the slg8sp626.

    If I had a slg8sp626, I'm sure I could find the correct way to set your PLL for higher Clocks, but it takes Debugging that I just can't do without the Machine in front of me.

    If your willing to learn how these PLL's work, and some basic Computer 101, I'm sure you can find a way to send the FSB Higher.

    First, have a look at the Data Sheet for the SLG8LP622V on Silego's site, read it until you have a basic understanding of how the PLL works. The main part you need to understand is simple, Table 1. PLL 1 (CPU) Frequency Select Table on page 5, Table 2. PLL 3 (ATIGCLK, SRC, SB_SRC) Frequency Select Table on page 6 and Table 3. PLL 4 Frequency Select Table on page 7.

    Also, Control Register Summary from page 10-16.

    It's OK to be confused about this, Please feel free to ask questions, but I'll refer you to This Thread @NBR, as this is a Bios Modding Sub-Forum.

    Just ask any ?'s in that thread and I'll be happy to help you.

    First of all, i dont have any system instability problems :) Second of all, I dont have any cooling problems, as i made a usb fan for my laptop using an old computer fan and the laptops box :p (actually works like a charm w00t). And like Darth said, i think my board is 626 and not 625, which is not supported by setfsb... I might wait till clockgen is out and then try... Thanks for all your help... And BTW i can run games that have min requirements of 2.0ghz on my laptop no problem :D (on minimum settings) :D Love these forums and thanks Darth_Vader for the help...
