    I never got it to work with 4gb... Only 3gb (1+2). And only in a specific configuration.. I mean, if I switch the rams in the slots, it stops working...

    200 -> 266:

    [​IMG]

    Thin orange line follows FS_B trace. Red line shows ideal spot to cut (I stabbed the board with a box cutter repeatedly, checking progress with an ohmmeter). Conveniently, there's a ground point right next to FS_B below cut. Green line shows points to bridge (may not be necessary? I did a quick test with FS_B floating and booted at 266FSB). Using a resistor to pull-down would be best. Otherwise, a blob of solder or conductive ink will do.

    Voila:

    T6500 10.5x200=2100 -> 10.5x266=2800
    ddr2 333 -> 443

    One of my sticks couldn't handle it. Will have to reprogram spd to either increase latency and/or remove 333 table.

    Crucial stick is pretty impressive. Rated 333 5-5-5 and runs 443 5-5-5 just fine.

    Dropped VID from 1.15 to 0.975 :)

    update: not sure if I don't have a good connection to ground, but after prolonged suspend, it wakes up at 200fsb. Requires a full power down to go back to 266.

    I noticed the final F35 bios is missing the 1067a microcode. I found a blog post by donovan6000 (http://donovan6000.blogspot.com/2013/06/insyde-bios-modding-cpu-microcodes.html) but it was taken private. I managed to use phoenix mod tool to pull the microcode, but wasn't sure if I could just inject additional microcodes beyond the existing ones, so I replaced two of them with the latest 1067a (it's platform 5,7 instead of 7 and is 2k in size instead of 1k). Updated the 10676 microcode as well just in case. Flashed it, but it didn't seem to change anything. Coretemp still gets stuck on a single snapshot. Still see ACPI errors in event viewer (assuming it's related to http://home.icequake.net/~nemesis/blog/index.php/archives/505/comment-page-1

    The good news though is that it seems to be sticking to 266fsb after prolonged suspend now. Maybe the liquid copper is making a better connection to ground now.

    Presario C700 series C777tu Insyde Bios

    After the cpu was upgraded to T8300 , the laptop sometimes cannot pass post on boot .It is intermittent.The issue is most probably the microcode.

    Please help me update the latest 10676 and 1067a microcode to the bios F.35 .



    The original BIOS is here: sp48079.exe



    Your help is greatly appreciated
