    Default Ga-ep35c-ds3r cpu multiplier problem

    hello,

    Since a few weeks i have this new motherboard, the "GA-EP35C-DS3R (rev. 2.1)".
    The problem is that my CPU the E8400 is running very nicely but there is a problem with the multiplier in the bios settings.
    I should be able to set it to 9 but the max i can set is 8.
    So i flashed my bios to the F3 version with q-flash, load optimized defaults, and rebooted in windows.
    Rebooted again and stil no difference.
    I've been breaking my head on how to fix this problem, and thats why i'm here.
    I hope someone can help me out here or maybe i am doing something wrong and can tell me so.
    My system specs are:

    GA-EP35C-DS3R (rev. 2.1) bios version F3
    Intel Core2Duo E8400
    Bfg 8600 gt
    Corsair 2 GB XMS2 TWIN2X2048-6400
    PSU is 570 watt
    xp 32 bit sp3


    thx in advance and happy holidays

    Does CPu-z report the CPU as an E8400? CPUID

    Also have you got the Fine Cpu Multiplier to 0.0x, rather than 0.5x?

    You may need to clear the Cmos, if the problem persists.

    Edit:-
    I assume you are saving to the bios (F10), after you have loaded up the optimised defaults?

    Thx for the quick reply, especially at these days.
    well cpu-z identifies the cpu correct, wolfdale etc.....
    I also have the fine cpu multiplier option but itrs set to 0.0x,
    and i can only change this setting when i change the multiplier to 7 else i cannot change them.
    Yes i use f10 always to save my changes after i alter something in the bios.
    I'll clear my cmos, and see what happens;
    Thx

    Edit:
    I cleared the cmos, removed the battery also for about 5 min.
    After i loaded optimized defaults, and its fixed.
    I've been breaking my head and it was that easy.
    thank you and have a merry x-mas

    regards xenomorph00

    Pherhaps if possible i have another question, since i have run memtest and spotted some errors i'm on the lookout for some new memory, can someone give me some advice or maybe even name a few which are good with this motherboard.
    Thx

    Try setting in MIT section of the bios:-

    1) Performance Enhance = Standard

    If the memtest errors still occur, keep setting (above) to standard and:-

    2) Increase DDR2 voltage to 1.9 or 2.0volts

    hello again,

    i already tried upping the voltage.
    I succeeded but i needed to pump it up till 2.1 volts.
    this seems reasonably high to me but it depends form motherboard to motherboard i think.

    Did you select Standard for Performance Enhance ?

    You could try relaxing the main timings too, to 5-5-5-18 to allow you to back of the voltage to say 2.0volts.

    yes i always use standard, i like to set my own timings.
    yes that is a possibilty, to run at these timings, but how will the effect be performance wise?

    The difference would be small. The only setting that affects memory performance massively is tRD.
    Use Memset for on the fly Windows tweaking and Everest Benchmark/Diagnostic suite to quickly benchmark the memory throughput differences.
    tRD has a downside too. Increase Performance too much and you'll compromise system stability. In general, Lower = Performance, Higher = Stability (tRD)
    You can also Increase stability (although its more of a must on 4GB+) by increasing the tRFC value by say 10%.
    Memset won't completely reflect the figures in the bios, because on a couple of settings there is a fixed offset, ie 4 = 8 & 5 = 9 etc.... All the rest are like for like.
    Memtest is useful because if you have left any values on Auto, such as Static Read Phase, you can see what the bios has automatically set them to (whilst you are in windows).
