I am on the A1 board - Whenever I overclock I get a black screen on boot up. The monitor says no signal. I know I can just reset the cmos but I would really like to figure this out so I can a stable overlock.

These are my overclocked settings:

3.4GHz

CPU Clock Ratio ( 20)
CPU Host Frequency (Mhz) ( 164 )
CPU Uncore Frequency (Mhz) ( 20x )
Spread Spectrum ( Disabled )
PCIE Frequency (Mhz) ( 100 )
Memory Feature
Memory Control Setting ( Enabled )
Memory Frequency ( 2:10 1333 )
Channel Interleave Setting ( 6 Way )
Rank Interleave Setting ( 4 Way )
Parameters
tCL Setting ( 8)
tRCD Setting ( 8)
tRP Setting ( 8)
tRAS Setting ( 24)
tRFC Setting ( 74)
Command Rate ( 1T)
Voltage Control
EVGA VDroop Control ( Without VDroop )
CPU VCore ( 1.28125 )
CPU VTT Voltage ( +125 )
CPU PLL VCore ( 1.8 )
DIMM Voltage ( 1.575 )
DIMM DQ Vref ( +0 )
QPI PLL VCore ( 1.15 )
IOH VCore ( 1.225 )
IOH/ICH I/O Voltage ( 1.6 )
ICH VCore ( 1.15 )
PWM Frequency ( 800 )
CPU Feature
Intel SpeedStep ( Disabled )
Turbo Mode Function ( Enabled )
CxE Function ( Disabled )
Execute Disable Bit ( Disabled)
Virtualization Technology ( Disable)
Logical Processor Setting
Intel HT Technology ( Enabled )
Active Processor Cores ( All )

1st thing is enable vdroop then try to add a bit more vcore voltage.

I got it, the CPU Uncore Frequency (Mhz) was set to 24 and needed to be 20, I am running at 3.4 right now and will go up some more tonight.

You have SpeedStep disabled but HT enabled? Did you update the Bios? I know evga boards crave bios updates...

The CPU Uncore Frequency has to exactly double the memory multiplier for stablility. And the QPI voltage may need to go up a little...don't push it up coz i said so...just a suggestion. I think 1.4v should be ok.

I've seen people using 4GHz on the CPU with the 1.3Vcore. I think your vcore is a little high but will probably stop the blue screens.

Yeah, you can add alot more qpi voltage than you can vcore.

It doesnt damage the chip as much.

I have it clocked at 4.0 with no issues, 20 passes on LinX and 2 hours on Prime95!
