Newbie 3.4ghz/3.6ghz Overclock Guide for EVGA x58 SLI LE with Intel i7 920 (D0)

post #1 of 6
Thread Starter 
Hey everyone. I recently built a new pc and I had to do a lot of research since this was my first time ever overclocking and my first i7 build. After a month of research and building 3 pc’s with the exact same parts, I’ve put together a great guide/log of notes. I wanted the best and safest overclock for EVGA’s x58 SLI LE motherboard paired with the Intel Core i7 920. I wanted to achieve a stable and safe overclock of at least 3.4ghz/3.6ghz. I found these settings work best for me. Please note I did not write it completely myself. I took notes/advices from several forums. I just wanted to put together a quick guide for anyone using this combo. If there is something wrong or something someone wants me to remove, please tell me and I will be happy to. Please note I am not responsible if you do damage your computer. Please read and read again and check your settings and take your time!!!!!!

Newbie Overclock Guide for EVGA’s x58 SLI LE and Intel Core i7 920 (D0)

This guide is meant to be SUPER EASY with mostly everything set to AUTO. If you want to overclock more than 3.6ghz, please see post 2 in the future.

Guide at 3.4ghz/3.6ghz

Step 1

Make sure you have everything up and running and put together correctly!

Download CPU-Z
Download LinX
Download Prime95

Step 2

Get your ram settings set correctly in the bios first. I will show an example with my ram.
I have the Cosrair TR3X6G1600C7D Dominator 6gb DDR3 1600mhz. They are rated for 7-7-7-20 at 1.65v.

So in the bios, you will set it like this:

In Frequency/Voltage Control > Memory Feature

Memory Feature
Memory Speed = Standard
Memory Control Setting = Enabled
Memory Frequency = 2:8
Channel Interleave Setting = 6 Way
Rank Interleave Setting = 4 Way
Memory Low Gap = Auto
tCL Setting = 7
tRCD Setting = 7
tRP Setting = 7
tRAS Setting = 20
tRFC Setting = Auto
Command Rate = Auto

Now you will set your ram’s voltage like this:

In Frequency/Voltage Control > Voltage Control

Voltage Control
EVGA VDroop Control = With VDroop
CPU VCore = Auto
CPU VTT Voltage = +100
CPU PLL VCore = Auto
DIMM Voltage = 1.65
DIMM DQ Vref = +0mV
QPI PLL VCore = Auto
IOH VCore = Auto
IOH/ICH I/O Voltage = Auto
ICH VCore = Auto

Step 3

In Frequency/Voltage Control > CPU Feature

I recommend having these disabled for now. You can enable whatever you need after.

CPU Feature
Intel SpeedStep = Disabled
Turbo Mode Function = Enabled
CxE Function = Disabled
Execute Disable Bit = Disabled
Virtualization Technology = Disabled
Intel HT Technology = Enabled
Active Processor Cores = All
QPI Control Settings = Enabled
QPI Link Fast Mode = Enabled
QPI Frequency Selection = 4.800 GT/s (Default i7 Limit Regardless)

Step 4

In Frequency/Voltage Control

Dummy O.C. = Disabled
Extreme Cooling = Disabled
Memory Feature = [Press Enter]
Voltage Control = [Press Enter]
CPU Feature = [Press Enter]
CPU Clock Ratio = 20x (You will see 21x below due to having Turbo enabled)
CPU Host Frequency(Mhz) = 163 (3.4ghz) or 173 (3.6ghz)
CPU Uncore Frequency(Mhz) = XXXXMhz (16 X) (Twice the Memory Frequency 2x8 = 16)
Spread Spectrum = Disabled
PCI Frequency(Mhz) = 100
OC Recovery = Disabled
Turbo Performance = Disabled

Step 5

Reboot and check to see if everything is up and running.
Run CPU-Z and check your overclock. You can now run LinX 20 times or more or run Prime95 for several hours (10 hrs+).

Enjoy your overclocked Intel i7 920 at 3.4ghz/3.6ghz

Note: I will edit as I go, I am currently OC'ed to 4ghz. I will add an advance optional step in the next post within a week or so.

Please feel free to let me know if I need to make any changes/corrections to make this even safer.

hello, i tried your settings and at first everything was fine, i did a prime 95 test for 1 hour and nothing happened so i went back and switched the BCLCK to 173 and then it gave me a BSOD...so i went back and switched the BCLCK back to 163, but it would give me a BSOD as well. I'm back to stock speeds since the BSOD won't go away.

In essence just because same cpu is used like He has i7 920 and you happen to have a i7 920 not necessarily means they would O/C the same tweak. Work around some of the setting and u might see a bit of stability. Like lower some or raise them but at small increments.
