HELP! Is this the i7 920 settings to 3.8ghz?


May 4, 2008
Hey is this the correct or good settings in bios to get my i7 920 to 3.8ghz stable?

CPU Clock Ratio ( 19X )
CPU Host Frequency (Mhz) ( 200 )
CPU Uncore Frequency (Mhz) ( 3205Mhz 16X )
Spread Spectrum ( Disabled )
PCIE Frequency (Mhz) ( 100 )

Memory Feature

Memory Control Setting ( Enabled )
Memory Frequency ( 2:8 )
Channel Interleave Setting ( 6 Way )
Rank Interleave Setting ( 4 Way )
tCL Setting ( 9 )
tRCD Setting ( 9 )
tRP Setting ( 9 )
tRAS Setting ( 24 )
tRFC Setting ( 88 )
Command Rate ( 1T )

Voltage Control

EVGA VDroop Control ( With VDroop )
CPU VCore ( 1.3250 )
CPU VTT Voltage ( +150mv )
CPU PLL VCore ( Auto )
DIMM Voltage ( Auto )
DIMM DQ Vref ( +0 )
QPI PLL VCore ( 1.300V )
IOH VCore ( Auto )
IOH/ICH I/O Voltage ( Auto )
ICH VCore ( Auto )
PWM Frequency ( 800 )

CPU Feature
Intel SpeedStep ( Disabled )
Turbo Mode Function ( Disabled )
CxE Function ( Disabled )
Execute Disable Bit ( Disabled )
Virtualization Technology ( Disabled )
Logical Processor Setting
Intel HT Technology ( Enabled )
Active Processor Cores ( All )
QPI Settings
QPI Control Settings ( Enabled )
QPI Link Fast Mode ( Enabled )
QPI Frequency Selection ( 4.800 )

Is there anything in here that screams trouble? Anything I should drop lower?
Some features that shouldn't be disable?
Please help I'm a nooby.

Well, i cant really say. It really depends on the chip. Mine took a little vcore increase to get to that but not that much. Yours may take a large increase in vcore.
This is how i would go about doing it
1.) Change the memory mhz to the lowest posible ratio.

2.) Chang the "QPI link speed" to the lowest possible setting (if you have this) it may be reffered to as the "QPI multiplier" (the lowest should be around x36)

3.) Change the uncore multiplier to the lowest setting.(should be around x14) And again, you may not have this.

4.) Start increasing your reference clock in 10mhz increments (your reference clock should start at 133 mhz)

5.) Save the bios and restart your computer. If it all works out fine then you should be able to boot into windows and log in...

If it all works fine and you dont get a blue screen then you can go into the bios and raise the refference clock another 10mhz.

6.) Keep increasing the refference clock by 10 mhz until you get a blue screen... When this occurs go into the bios and raise the voltage a little bit.

You should raise the vcore in very small increments and keep rebooting and seeing if you can get logged in without a blue screen.

you should also raise the QPI vcore in small increments.

7.) Repeat the process until you get to the speed you wanted to achieve.

And it would help us to know what mobo you are using.

i got the evga x58

my 920 d0 is running at 4.2ghz
i have the xig dark knight cooler
my cpu cores idle at around 42 and the high is 73

make sure your watching the voltage regulator temps on that motherboard it shouldn't be going over 85c. the voltage regulator can get very hot if not oc'ed correctly. keep that out of the 80's and your safe. i once saw mine hit 100c in prime 95 :(

i contacted evga support about it they say it can hit 105c before failing but they strongly recommend keeping it under 85c

my vreg temp doesn't go over 80c any more after proper cooling
