This link goes to the page showing the voltages they measured. Of course it's for a different CPU, but I'm going to try and decipher what I can from it now, and see what happens. The highest stable I've been able to get so far is 388x8.5. Judging by this table, I need to go higher with the voltages. It just keeps rebooting/crashing on me.

I don't know if this will help you at all, but i was having a problem where i couldnt get above 2.93, what i did is set my multi to 8 instead of 8.5 and now i have it at 3.73 on the x8 instead of 8.5, and i think im at 1.25 volts

i have got mine too OC still in progress

here is my current attemp

CPU-Z Validation

and an Overlook at my desktop testing

Set vcore to 1.35, FSB Termination voltage to 1.34 and FSB voltage to 1.34.

Put the RAM to 2.00 of the FSB (should be 1:1 with FSB at that point), and then go for 450 FSB

Q9550 E0 here reached 3.8ghz with 1.3375 vcore no LLC. cpu z validation: http://valid.canardpc.com/show_oc.php?id=558331 this me first ever attempted OC project and success prime95 ran large ffts 17 hours no probs im so proud lol.will update if i manage to get to lower vcore so um ADD MEEEEEEEEEEE!

What do you have your VTT (aka FSB termination voltage) set to? I ask because through my own research and personal experience I've found that too much VTT can cause instability just like too little. For example on my rig right now I have the following voltage settings for 3.8 GHz:

CPU voltage 1.33
VTT voltage 1.32
SB/CPU PLL 1.51 (default)
MCH (northbidge) 1.55
GTL ref 0/2 0.667x (default)
GTL ref 1/3 0.667x (default)

With the settings above I've passed initial stability testing (20mins Prime95 blend). However, with VTT set to 1.33 (and all other settings the same) I actually had a failure on the 3rd core in less than a minute and a half. With the VTT at 1.34 and up my system still posts but I cant make it into Windows.

Anyway, I just thought I'd share my findings with you. I hope it helps.

Ok Prime just gave an error on Core 4

So i was wondering what is a safe 24/7 overclock. i don't render stuff over night. i just keep downloading stuff..

Also i wanna know what do u think of my Idle/Load temp at those pics

Josh81 · 05-02-09

if you get a rounding error its probably northbridge or VTT

Josh81 · 05-02-09

Is my sensor broken or something?

My temps ; CPU 23 ; Core0/1/2 35; Core3 32
