Thread: EP45-DS3L Vcore reverts to default on cold boot

    Question EP45-DS3L Vcore reverts to default on cold boot

    Hi all,

    I increased my mobo VCORE a few months ago but every time I cold boot (system is off and then case power button is used to turn on) it reverts to the default vcore as defined by the CPU. I need to do one warm boot (system reboot using case restart button or windows restart option) to get the modified vcore value to stick. I use CPU-Z to check vcore.

    So basically, every time i turn on my computer, once windows has finished loading I do an immediate reboot. This always works to set the vcore properly, and after this point my system is stable. I've been doing this routine for 3 months. Now and then I play with bios settings to try and fix this but no luck yet. I haven't tried doing the reboot at earlier points yet in the boot sequence yet. On the occasions when I've forgotten to reboot i'm brutally reminded after a short while because applications will start crashing or the system will freeze.

    I've tried disabling 'cpu enhanced halt (C1E)', 'C2/C2E state support', and 'CPU EIST function' in the bios but it makes no difference. I've played with a few other settings, but nothing significant. Could it be my bios version?

    Here's my hardware:
    - GA-EP45-DS3L, board rev 1.0, bios F9
    - Pentium E5200 @ 266FSB (3.33GHz), 1.30625v(bios)
    - 2 x 1GB Kingston HyperX DDR2 1066 CL5
    - Corsair VX 450W power
    - Sapphire Radeon HD4830
    - Promise Ultra100TX IDE pci card
    - Seagate 200GB and 160GB IDE drives (promise controller)
    - Toshiba IDE DVD-ROM (promise controller)
    - Plextor IDE DVD+R burner (onboard IDE)
    - Plextor IDE CD burner (onboard IDE)

    Other details:
    - WinXP SP3
    - No SATA devices
    - DDR2 running dual channel in slot 1 & 3 @ 1.96v(bios) 800MHz, have not tried using just a single stick yet as I have no problems with posting/booting or random crashes.
    - Overclock stable in Prime95, Orthos, OCCT, 3DMark0X using various test types (CPU, mem, blend, graphics)

    Thanks for taking the time to read this.

    Still living with this issue. System is stable but getting tired of double booting all the time. Anyone have any ideas?

    In the meantime I'm working on the settings/advice in this post right now, will post details shortly.

    Problem Solved!

    The setting that was the issue is 'Legacy USB Storage Detect'. I had it set to Enabled all this time. Changing it to the the recommended setting of Disabled solved my vcore cold boot problem!

    Thanks much to this forum and all the great people contributing to it!

    FYI Here's my settings. System is and has always been 100% stable:
