Hi People. i want to OC my System, i need help. I want to know can i use this Bios Settings to my system?
 
MB- Evga X58 Classified 3way SLi
Core i7 950 3.07
3x2GB Corsair dominators
I want CPU speed around 4.0Mhz or 4.2 Mhz
Thanks, i had update BIOS 

Does Jacob's guide (on Page 1) of this thread overclock all four cores on the Bloomfield 920 chip or simply one core?  I ask this because I followed this to a "T" and went from 2.66ghz - 4.2ghz.  Yet, my windows 7 "experience" score didn't change at all.  It's still at 7.5 - The El33t tool shows one core at 4.2ghz, but I can't tell about the other cores.  Additionally, I can't say I see much of a performance increase either..  Any thoughts?

Very nice guide, thanks!!!!

you should never need 1.4+ volts unless you're benching with ln2 or dice.. for the average i7 you should't have to use much more than 1.35.. depending if you have a D0 stepped chip or not (you can tell using the CPU-Z application)
 
that guide isn't a template, just informative for you to get the ball rolling

Mower

Unrelated perhaps but if it freezes in Prime95 then that is a RAM setting/voltage?

Not necessarily. It would be best to start a new thread, plenty of people here that are willing to help. You will need to post your current BIOS template when you do so we know what you have done.
 
Also it is about time this one was removed from the stickies.

I've tried the template in the first post except i used 1.4vcore and had a BSOD during Unreal Tournament III.  I do NOT want to use the 'Turbo' feature through the bios; 21 multi.  I am looking for stability at 211 BCLK.  I'm using an EVGA 760 with the latest bios. 
 
help!

i did this, got my 950 to 4.0, but my 1867 ram is running at 1600 cuz i left it at auto, and if i try to OC it up to 1867 it either jumps to 2180 or 2400 ish, and then when i save and reboot my monitors wont turn on and i have to reset the bios with the button on the MOBO... any ideas? :/

bclk is 200
and multiplier is 20

bclk is 200
and multiplier is 20

For the memory I meant, 2:8, 2:10?

yeah 2:8 will give you 1600, 2:10 will give you 2000.  Remember on these newer systems, all of these clocks are ratios.  If you were at a BCLK of 175 your memory would be 1400 or 1750 at 2:10. 
You can try adjusting voltages some, but, being able to get 1866 ram stable at 2K can be quite a challenge, and might not be possible.  At which point your other 2 choices would be leave it be, or clock it to 186/187 BCLK (dropping your clock) and having the ratio at 2:10, or try to get your BCLK to 233 at 2:8 will get you 1864 on the RAM, but honestly, good luck hitting that BCLK.  I have seen it a few times, but normally on really good chips, volted like crazy and on extreme cooling.
 
If this was mine, I would leave it at 200, as long as everything is dialed in nicely, then I would try to see if I could tighten the timings some.

nevermind im back online i didn't event think of the damn cmos bios reset.. Anyway can i please get someone good with OC to pm. This is an old rig ive bought off of a buddy and im used to my sandy bridge! i want to oc this though if possible

First of all, I did the Load Defaults, Saved and Rebooted.  Then I set the following values in the BIOS.
 
On the Frequency/Voltage Control screen
    CPU Clock Ration: 20x (this is the default)
    CPU Host Frequency: 200
    CPU Uncore Fequency: 16x
    Everything else left at default values
 
On the Memory Features screen
    Memory SPD: XMP Profile 1
    Memory Frequency: 1067Mhz / 2:8
    Everything else set at Auto or default values
 
On the Voltage Control screen
    EVGA Droop Control: Without EVGA Droop
    CPU Vcore:   1.35V
    Everything else at Auto or default settings
 
This puts me at 4.189Ghz.  I could go faster but the temps start getting a little to high for me.  I have had it as high as 4.5Ghz by following the the settings that were presented on this page but my CPU Temps started getting to high for my likings.  

A few CMOs resets late... this worked much better for me than the OP.
