Okay so I have been attempting to OC my system recently. Everything I have read says that ocing E8400 should be easy as pie especially seeing as the OC i want to perform is very small.
I am trying to take my E8400 from 3.0ghz ot 3.6ghz. Now what I have done is Increase FSB to 400, set the ram/cpu to 1:1 ratio, and manually set my Ram timings to 5-5-5-12 as per specifications.
I have an aftermarket Scythe cooler installed with a Corsair PSU. I have disabled all the powersaving features.
After FSB was set to 400 (at 9x multiplier) I just slowly started bumping Vcore up each increment trying to find a stable overclock.
Around the 1.35 Vcore mark I was finally able to boot into windows however after 5 minutes the system would BSOD and reset. After I continued to bump this up all the way to 1.39 Vcore my system stopped booting into windows.
I have left all other settings to AUTO.
Why wont my chip overclock? Am I doing something wrong? Is there a setting I sohuld be playing with which I am not?
I will post up some SS of my BIOS later but here is everything as I set it:
FSB Strap to Northbridge 400mhz
DRAM Frequency – DDR2 800mhz (as my ram is)
Dram Timing 5-5-5-18 (as my ram states) everything else under ram is Auto.
LLC : Enabled
CPU GTL : Auto
CPU Spread Spectrum: Disabled
PCIE SPread SPectrum: Disabled
CPU Clock Skew: Auto
NB Clock Skew: Auto
CPU Margin Enhancement: Performance mode.
CPU Ratio Setting: 9.0
C1E Support: Disabled
Max CPUID Value Limit: Disabled
Intel Virtualisation Tech: Disabled
CPU TM Function: Enabled
Execute-Disable Bit Capability: Enabled
OKAY theres all my settings.
Now the only settings left to adjust are the Voltages.
FSB Termination Voltage: AUTO
Memory Voltage : AUTO
NB Voltabe : AUTO
SB Voltage : AUTO
From the pictures above I would do a few things. First turn on load line calibration. Second I would set the CPU voltage manualy to 1.25v +/-.05v it shouldnt need more than that to run at 3.6ghz. As for fsb and north bridge voltage you can play with them if you want but they should be ok on auto unless you overclock the cpu and/or the memory more. oh and make sure the CPU dont go over 70c in Prime95.
