dear members
I have intel core i3 530 2.93ghz pro (no turbo)
asus p7h55-v mobo
2gb ram ddr3 1333 , transcend
400 watt power supply
intel heat sink fan no extra cooling system
1gb integrated graphics card (intel h55)
my problem is at 180 BCLK and vcore 1.25v blue screen of death appears
at 180 BCLK i can achieve 3.9ghz
my target is 4.0ghz
can any one help me in this regard
thanks
My bios settings are:
Ai overclock tuner : manual
cpu ratio setting : 22 (no turbo so 2944/133=22)
xtreme phase full power mode : enabled
BCLK frequency : 180
BCLK/iGPU Frequency sync mode : auto
DRAM Frequency : DDR3 1050mhz
QPI Frequency : auto
CPU differential amplitude : auto
CPU clock skew : auto
***************************
Please key in numbers directly
CPU voltage mode [manual]
fixed voltage: 1.250
IMC voltage : 1.15000
DRAM voltage : 1.500
CPU PLL voltage : 1.80V
PCH voltage : 1.05000
iGPU voltage : auto
Auto PSI : enabled
At these settings system is unstable. (BSOD)

my temp is 66C at 175 BCLK vcore at 1.232v
multiplier x22 bus speed 174.9mhz and achieved 3847mhz
system stable

babbajee4u,
I recommend manually setting your DRAM voltage to 1.65V for added stability

Your BSOD problem may be due to the low IMC and CPU voltage you are using

Set the CPU voltage to 1.25V and increase your IMC voltage to 1.25V and check if the system is stable at 180BCLK

If it is stable back the voltage off to something lower that remains stable.


let me know how it goes 🙂
