Problem overclocking E7300 + Gigabyte EP45-DS3L

So for the past few days I have been trying to overclock the CPU to 3.33GHz, which failed even though voltage is at 1.25V.
Next step: overclock to 3.00GHz with 300Mhz at 1.2V, failed.

Maybe I'm doing this wrong by just upping only the voltage of the CPU vCore and frequency of it.

Here are the specs of the computer:

RAIDMAX SMILODON w/ 500W power supply
E7300 w/ stock fan from Q6600
Gigabyte EP45-DS3L
2x2Gb of Crucial Ballistix PC6400
BFG 9600GT OC
1TB Samsung Spinpoint

What confuses the most right now is the BIOS to overclock, as I'm use to the EP35 and not EP45.
Here is a list of the options found in the MB Intelligent Tweaker (M.I.T.):





The list of options pass the "Mother Board Voltage Control" is all new to me, so can someone explain what each of those does?

Sorry if I'm asking too much.

  1. I just discovered what my problem overclock thing thing was. Maybe it is the same for you.

    See your System Memory Timing is set to Auto which means it is overclocking with your CPU. Change it to manual and choose a setting that places it closer to 800mhz.
  2. See:GUIDE: Overclocking On EP/P35-DS3L

    As most of the settings are the same you should find that helpful.

    @OP: Seriously consider getting a better PSU. If you are using a RAIDMAX PSU be ver careful. That things a time bomb.
  3. Hi!
    (i write from hungary, sorry for the writnig error)
    I have a EP43-DS3L + E7300 + CM Hyper TX2
    Corsair TwinX 800Mhz (CL5) FAN kit 2*1Gb
    Gigabyte SuperB 460W
    Sapphire HD 3870 GDDR4 512M

    I overclock this E7300 to 3,4Ghz!
    This motherboar had a big Voltage drop.
    You set 1,3 V in BIOS, but CPU-Z show 1,25V

    So, my BIOS settings:
    In MIT:
    Fine cpu clock = 0
    CPU host contros = Enabled
    CPU host frequency = 340
    PCI-E frequency = 100
    MHC frequency = Auto
    System memory multiple = 2.50A
    DRAM Timing = Auto
    CPU Vcore = 1,3000 V
    DRAM Voltage = 1,9V

    Good luck!

  5. Sorry! :S
