    Default Mysterious GA-P35-S3G overclosking troubles

    Hi

    2 days ago I overclocked my E8200 2.66 Ghz to 3.3 Ghz by changing the FSB to 400 (from the default 333) and memory SPD to 2 (from auto) I didn't touch any other settings, no messing with voltage or RAM timings, nothing. The computer booted up ok and was completely fine all day. I didn't run any stress test but I was watching movies and gaming. Not a single issue, everything was fine. Next day when I started up the computer...everything was still fine, running at 3.3 Ghz, was running the entire day, temperature never exceeded 51 degress Celsius, again not a single issue. In the evening I restarted it and boom - it wouldn't boot up - just failed during post and restarted again with default settings (everything in MIT set to auto)
    I tried various settings, messing with voltages and whatnot but no luck - I can't get it to boot with anything else than default settings - even raising the FSB by 1 Mhz makes it fail booting

    I really don't know what to try, I'd understand if it wouldn't OC at all but why woul it be working fine for 2 days and the suddenly fail?

    using the following RAM Patriot DIMM 2048MB DDR II 800MHz PSD22G800KH - Czech Computer | czc.cz

    and this PSU Fortron Blue Storm II 500W - Czech Computer | czc.cz

    here is a cpuz screen I made when it was still working



    Any help would be greatly appreciated

    Load BIOS optimized defaults for now, with changes you need like disk boot order.
    Increasing FSB alone with auto voltage settings is not recommended.

    okay, I got home, turned PC on, entered BIOS, set FSB to 400, SPD to 2, saved and...it booted just fine and is running at 3.2 Ghz



    I really don't know why it's suddenly working again (but who knows why and how long)

    anyway here are the specs and settings (hope you won't mind it's pictures)


    CPU:



    MB: GA-P35-S3G



    RAM:





    BIOS settings:







    Like I said, all I did was enabling CPU host clock control and setting it to 400, and changing system memory multiplier (SPD) to 2x from the default auto (which was setting it to 2.40), everything else is set to auto

    Anyone knows why it's behaving so strangely ? :( I would rather have it not working at all instead of working only when it wants to :(

    Thanks for any help

    Voltage settings do not look like default settings.

    It's set to auto, those settings aren't being used

    anyway, it held for 2 restarts, booted up fine and stayed at 3.2 Ghz so I went for the ultimate test: turning the computer off and on again

    sadly, it didn't past POST again, failed to boot and reset everything to default settings

    I honestly really do not know what's up with this

    There were 3 BIOS updates for this board since F2, you may consider updating, at least to F3.
    F3 2008/03/17 1. Update CPU microcode
    If you choose to update, read http://forums.tweaktown.com/f69/bios...h-guide-27576/.
    Never update BIOS with OC settings.

    What kind of CPU and case cooling do you use?

    For 3.2GHz, load optimized defaults, save & reboot, enter BIOS again and try the following changes:
    Code:
    CPU Clock Ratio ____________ [8] 
    Fine Clock Ratio ____________[0.0]
    CPU Host Clock Control_ [Enabled]
    CPU Host Frequency (MHz)__________ [400] 
    
    PCI Express Frequency (Mhz)_______ [100]
    System Memory Multiplier (SPD)____ [2.00D]
    DRAM Timing Selectable_______ SPD __ [Manual]
    
    Performance Enhance________________ [Standard]
    
    System Voltage Control____ [Manual]
    DDR2 OverVoltage Control__ [normal] <<< +0.1 if not enough
    PCI-E OverVoltage Control_ [normal] 
    FSB OverVoltage Control___ [+0.1V] 
    (G)MCH OverVoltage Control [+0.1V]  <<< +0.2 if not enough
    CPU Voltage Control_______ [1.25] <<< morr may be needed, max by Intel 1.3625v

    okay, overclocked it again, turning up the VCORE to 1.345, it survived another 2 restarts and even turning the computer off and on this time so I thought i had it, I turned it off again to make sure and guess what - it failed to boot again and reset :(

    I guess updating the BIOS is really my last option, I've never done it but it doesn't seem to be hard, just hope it won't kill the MB

    What kind of CPU and case cooling do you use?
    case: Thermaltake VG1000BNS Wing RS100 - Czech Computer | czc.cz , there are two fans in there

    CPU cooler: Arctic Cooling Freezer 7 Pro - Czech Computer | czc.cz

    like I said, the temperatures hardly went over 50 degrees Celsius when running at 3.2 Ghz and they're around 48 degrees now at 2.66 Ghz

    http://www.tomshardware.co.uk/forum/246710-12-problems - this is the exact same problem I am having - and it seems there is basically no solution :/

    okay, I flashed the BIOS to F3 and it looks like it helped - been running at 3.2 Ghz for 2 days now, went through almost 10 power off/power on and numerous restarts and it seems to hold

    however when I tried a higher FSB than 400 it failed to POST. I think it's the memory that's to blame but I'm not sure - I've seen people running PC6400 at 900 Mhz. Can anyone suggest some settings I should try?
