OC'd to 3.8 GHz Blue screen after hot cpu test???

Okay so ive managed to get a 3.8Ghz overclock but its far from stable

Base Clock frequency 195MHz
CPU-z Core speed: 4.095.0 MHz
Core Voltage: 1.200 V

problem: after running hot CPU tester pro for aroun 1-2 minutes i get a blue screen with crash dump info so im raising the Vcore up slowly... is this correct?
keeping in mind my memory frequency is set at 6.0 have yet to raise it back up!

Edit: UPDATE-------> SEEMS STABLE WHEN MEMORY MULTIPLIER IS SET TO 6.0 'LOWEST' BUT WHEN I GO TO BUMP UP THE MEMORY FREQUENCY WITH VCORE/VTT/ DRAM V UP IT DOESNT LIKE IT 1 BIT..

I'LL TRY KEEP MY MEMORY SET TO THE LOWEST AND BE DONE WITH AN OVERCLOCKED CPU ^^
TESTING OVERNIGHT FOR A 24HR TEST RESULT

Core Speed 4200.0 Mhz
Core Voltage 1.232 V
NB Frequency 3200.0 Mhz
Dram Frequency 600.0 MHz--> standard i think it runs at 500.0 MHz

  3. How are you running 8 Gb's of ram?

    I'm guessing 4 X 2 Gb sticks, and if that's the case take the one NOT in triple channel out.

    Then yes, you will most likely have to up the vcore and vtt voltage for stability.
  4. Update of stabilty test results '1 hour' no blue srceen+ screenshots of current BIOS settings :)





    would anyone know were to find the DIMM Voltage? it's the DRAM Voltage?

    Yes 3 corsair 2 Gigs, and 1 Geil 2 Gig in the fourth channel... thanks i will remove that one i didnt realize this was an issue :)
