OC Q6600 to 3.4GHz (stable @ 3.0)

post #1 of 6
Thread Starter 
Alrighty,
Well, I should introduce myself first.
I'm a newb OCer and builder who joined this network just about a month ago. I learned that there is no option of taking small steps to reach my current target which 3.4 GHz. I mumbled and jumbled inside my Bios to 3.2 GHz, but never checked stability seriously and went up to 3.4Ghz and crashed until I decided that asking help from the more experienced wasn't so much a bad thing.
After some revolutionary tweaking(3.0GHz with stability proof was rev for me ), I noticed that just juicing my voltage wouldn't get me to 3.4 & +. Also, I only can understand 50% of whatever it says in my DFI bios. OWW, that's too much rubbish to start.

This will be a better intro:
Hi, I'm a self-educating newb, I'd already passed CPU/Mem stability using prime and memtest. So, we can start from here, Right here @ 3.0GHz and

Target: boost up my system to 3.4GHz.

A. Status up to present:
  • Tested small ffts prime95 64bit ~ 10hrs(pics attached for evidence)
  • Three passes for memtest(I doubt my mem is unstable)
  • CPU V @ idle: 1.248 V
  • CPU V @ loaded: 1.20 V (Voltage drops, IDK y; didn't do any Vdroop mod)
  • Core Temp @ idle: 34-40 ish
  • Core Temp @ load: 50-56 ish
  • FSBRAM --- 4:5

C. Questions:
Why there is Vdroop mod if you can change V in bios?
Do you think Vdroop mod is neccessary in my case(not the space)?
What is Clock VCO Divider and its effects?
Can you explain the Peformance lvl and tRFC?
Is my core temp normal?

Q#1= people just like it to read the same in the bios as it does in windows.

Q#2= if the difference does not bother you than no.

Q#3= has something to do with gpu "leave on auto"

Q#4= its a memory timing parameter "Leave alone"

Q#5= YES

thats a very nice quad you've got there... vid 1.2250V, you should beable to get a high overclock with it.

^^ Uh voltage changes under load which could make your OC unstable, thats why I did the pencil mod, no vdroop means you can set a lower voltage and not have it drop once you have booted and not drop again once under load. I used to have to set my CPU voltage to 1.45 to get stable at 3.2ghz after pencil mod I can get stable at 1.39...

Can you give me voltage and mem timing suggestion or good configuration?

I can't seem to hit 3.4ghz i'm happy with 3.2ghz anyway as for a suggestion, all chips are different so uh idk ;D What voltage have you tried at 3.4ghz? Bumping your northbridge voltage a little may help stabalize.. I'd aim for 3.2ghz if I was you then if and when you get stable at that, try for 3.4ghz. Takes more patience which I have none off but yeah...
