   Posting because I noticed there we're a few forum members like myself looking for some type of overclocked bios settings for the I7 950 using the SLI LE board. Well this is what I have so far and would like to thank JacobF for the overclocking guide http://forums.evga.com/tm.aspx?m=20028 the main difference I found is that I have to use the multipler to get the system stable beyound 3.8ghz. I will say that the I7 950 is alot tougher to get past the 4.2ghz and expect to install a water cooled system to achieve anything higher than 3.8ghz.
  Would like to thank the community members HarryD , jmcu1 , MrRiddler , kyozero ,moose517 For selling certain items I needed to complete my first water cooled system. Some of them still have parts for sale and all transactions went great.

First my specs:
Case: Cooler Master CM 690 II
Mobo:Evga X58 SLI LE Thanks to HarryD
Cpu: I7 950 D0 S-SPEC: SLBEN, Temp= 26c idle 52c loaded, Running 4.2ghz, 200 fsb, 21x multipler (can't seem to get stable using the full 23x), 1.475 core voltage not sure if I can go any higher or if I'm to high now.

    These setting are what works for me right now. I can not get stable using full multiplier and keeping the ram around 1600. I might try increasing the ram dim voltage a little more to try and overclock the ram to get the system stable @ 23x multiplier which would put me @ 4.5ghz roughly.
    I have read that the ram voltage can be only .5 volts max higher than the Cpu Vcore voltage. If I understand this correctly than I should be able to easily set the Ram Dimm voltage to 1.7v to help keep the ram stable Since Im @ 1.475 on the Cpu Vcore. Let me know if im reaching the limit on Cpu Vcore or the Ram. Has anyone ran a system higher than 1.475 for a fixed amount of time?  I am still playing with voltages and multipliers.
   These settings are prime 95, Intel Burner , Vantage, and OCCT stable. If anyone has any suggestions please add some comments. Hopefully this might help someone else that might be fighting to get there I7 950 higher than 3.8ghz. I would like to thank the community for their time and help.

    First, not many like Jacobs guide, it was designed for C0 920. Shansmi's is much better and it teaches you the proper way to overclock. They require a lot of voltage. You should only need 1.40v or less depending on what you are doing with the rig. I require 1.4375v for 4.2GHz on a 930 to fold stable. 4.2GHz is easy for most CPU's, to start just put the Multiplier at 21 and the Bclock at 201 for clock drift otherwise it will show up as 4.19GHz if you put 200.
     
    I have read that the ram voltage can be only .5 volts max higher than the Cpu Vcore voltage. If I understand this correctly than I should be able to easily set the Ram Dimm voltage to 1.7v to help keep the ram stable Since Im @ 1.475 on the Cpu Vcore.

     
    This here is slightly wrong. It's .5 of the CPU VTT, NOT CPU Vcore.
     
    You can also probably bring your CPU VTT Voltage down to +200, you are past Intel Specs for voltage on that one. It can be ran there, and many do. I would try to bring it down some. Can probably also run your RAM at a command rate of 1T as well. Most of the time when you use 2T is really low timing around CAS 6 and if the manufacture specifies so. Also use 2T if you have 12GB of RAM.
    NEVER use the XMP Profile when overclocking, that is only if you are going to run your CPU at stock and you aren't sure on how to set the Divider and timings. Can probably try to bring a lot of those other voltages down as well.
     
    I know this seems like a lot, but I'm pretty confident others would agree with me.
    If I was in your shoes, I would read these two guides, and go slow. Overclocking doesn't happen in a day.
    How to Overclock the I7 (Ported)
    3 Step Overclocking Guide - Bloomfield and Gulftown
     
    Edit-
    These settings are prime 95, Intel Burn Test ...... Stable.

    How many passes of ITB and how many hours of Prime? Recommended to run 20-25 passes of ITB and 9-12+ hours of Prime95.

    Also getting to 4.2 will show if you have enough cooling.  As in my case I could of easily gone 4.2 if it wasn't for my HS not up to the task.

    Hi MAny thanks for this VERY simple walkthru, i still have and game on my now very old x58 sli3 i7 950
    Having following your steps im now running my 3ghz at 4.2ghz and it feels like a new pc getting around an extra 30fps in some games (arma based , pubg,csgo)
     
    on this line tho CPU CLOCK RATIO[<font] [21X] [CPU HOST FREQ [[MCH STRAP [AUTO] 
    the cpu host freq i guessed at 200 incase anyone else reads and was wondering, worked great for me,
     
    Again many thanks
    Enjoy gaming !
