    Hi all,

    I have mentioned GPU (core r423, 256MB mem) in my laptop and obtained the BIOS via manufacturer. (see attached)
    -I'm a bit afraid to edit/amend the BIOS and flash it as I don't know what this will do to, for instance to Powerplay.
    -I also would like to know if amending tv-out to PAL is possible (and what is PAL-60?).
    -I don't know my mem-type, how can I findout?

    Who can advise or has experience with modifying Mobility BIOS?

    standard clock:
    450c/500m
    3dmark05: 5402
    max overclock (with ATI tool):
    500c/540m
    3dmark05: 5902

    mem timings from BIOS:
    tWL = 1.5
    tCL = 3
    tCMD = 0 clock
    tSTB = tWL
    tRcdRD = 7
    tRcdWR = 4
    tRP = 5
    tRAS = 6
    tRRD = 6
    tR2W = CL + 2
    tWR = 7
    tW2R = 0
    tW2Rsb = tW2R Rule
    tR2R = 1
    MemRR = 3C
    tRFC = 21
    tRBS = CL + 2
    tERST = CL - 2
    tQSREQ = CL - 2
    tDQM = WL - 1
    tDQS = WL - 1
    tDQM_Adv = As specified
    tDQS_Adv = As specified

    Flashing the laptop bios. It will probably overheat. I would stay away. I have a laptop with a mobility 9600, but I don't need to flash it. Overclock it with ATI tool.

    But I know my GPU can reach higher speeds.
    standard:
    450/500
    max save OC:
    500/540

    I'm thinking of setting the clock a little bit higher and tweak the memory timings.
    But I don't know how to do so and don't know what this will do to Powerplay (which I also use often).
