i7 920 OC help...

California Icrontian
I have read the setting for Goods and drummers setups but with allt he info all over and attempts done I would like to get a direct setting for my system and its mobo. This thing has so many options I have no idea if I am change the wrong thing or not.
Here are my BIOS screens... any direction on what to adjust is much appreciated.
I am looking to get 3.8GHz... just don't want to jack the wrong setting and fry the system.

This is from Thrax in my post and once i've found every setting and apply it this is what enabled me to run stable at 3.8Ghz / 1600-DDR. With those settings you'll see if you can achieve stable DDR-1600 ram settings. (with an underclocked CPU so its out of the equation as much as possible)
The only thing that is labelled a bit diffrently in your bios is :
Core voltage -> cpu vtt voltage
You should manage to find any other settings listed in the quote i think.
If it boots and is stable with some memtest bench, you just take the CPU Multiplier to 20X and you'll run at 3.8 instead of 2.4Ghz.
Then you do some memtest again, if stable 1hour or so, you boot into windows and do some LinX bench or any other good windows stability bench. If stable than your gone, you could do the twist again and try to reduce the cpu vtt voltage if you want but otherwise the OC is complete.
let us know how it goes.
Is that the CPU VID Control?
Also my QPI options are different... let me get some screens...
He'res a screen of my bios, i chosed X36 after the screen was taking and the bios told me its 6.5G
To be sure on your case i would look on the net for some guys with ur board and ur bios to see in overall what setting they use for stable OC.
Or ask Thrax he surely knows that he seems to know the new i7 DFI board
For the VID :
Thats a full definition found on google lol
So no, its not uncore voltage.
Sorry I haven't really had time to help more, Sledge. I've been doing the ICOK thing, and I've been away from my PC since Wednesday or so.
Here are some suggested settings:
EIST/Speedstep/C1E/VT: Disabled
Spread spectrum: Disabled
Any shadowing options: Disabled
Bclk: 200MHz
CPU Frequency: 4000MHz (200*20 )
DRAM Frequency:1600MHz (200*8)
QPI Frequency: 4400MHz (200*22) or 3600MHz (200*18)
UnCore Frequency: 3200MHz (200*16)
DRAM Voltage 1.65v (Default varies)
CPU PLL Voltage: 1.88v (Default 1.8v)
CPU VTT (UnCore) Voltage: 1.35v (Default 1.2v)
CPU Voltage: 1.375v
DRAM Timings: By SPD
This should get you to 4GHz, but it might be on the hot side. Try to back down your vcore if you can. All of these voltages are within Intel's specs.
I got my ram stable at DDR-1600 with 8-8-8-19 , with 1 hour memtest bench without error with CPU MULTI X12 , then i just pushed the cpu multi up and i was flying at a rock solid 3.8Ghz, and even 4Ghz with way more heat :P
Note : Use every voltage Thrax posted as a start, in my case, before i got my CPU PLL Voltage: 1.88v (Default 1.8v) , my computer wasnt even booting at those settings. 1.88 and now it boots and its rock stable :P
CPU Frequency: 4000MHz (200*20 )
DRAM Frequency:1200MHz (200*6)
QPI Frequency: 4.800MHz (200*18*2)
UnCore Frequency: 3200MHz (200*16) - Not even sure where to set this?
DRAM Voltage 1.65v (Default varies)
CPU PLL Voltage: 1.85v (Default 1.8v)
CPU VTT (UnCore) Voltage: 1.34v (Default 1.2v)
CPU Voltage: 1.375v
DRAM Timings: 9-9-9-24-92
With the CPU running at 4GHz I was able to drop down the Voltage to 1.215V and keep the system stable. I started to go lower & was getting the system to BSOD every so often. but with 1.215 it hasn't crashed yet.
Set the Bclock to stock (133) and the memory to 1600 to test the memory.
So I tested the above and the system would not boost past the windows welcome screen.
Tests:
133x12 with mem at 1600MHz - Won't post
133x12 with mem at 1333MHz - Boots & runs fine
200x19 - Won't post
150x19 with mem at 1500MHz - Boots with a hard crash when running Super PI 1m
190x19 with mem at 1520MHz - Boots into Windows & crashed on 2nd run on Super PI 1m
