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.
