I'd even take a pink one...

I was scared by my temps after like 30 mins of stressing my 4GHz and shut down and ran outside like I was on fire.

#3 What is your vcore showing in CPU-Z? Both idle and under load. Idle 1.32v Load 1.25v

For kicks I tried LLC enabled at 1.34v and actually failed at end of first run of Linx (just said "stopped due to error at 2m 2s")

I can only pick 1.32 or 1.34 for CPU term so I'll try 1.32 first...do you guys with UD3P boards have CPU term options in increments of 0.01? Why would my bios options be so different? I don't need crossfire but if I knew the bios would be different I would have paid the extra for the UD3P...

No I think most of the options are the same. I said 1.33 as an estimate. 1.32 might get you there. Also I would enable LLC but if you so don't put in more than 1.40 for vcore with it on.

Your temps are getting pretty high, you know that right? Linx/IBT are going to do that. You may want to stress the cpu oc with Orthos/Prime95 to keep your temps down.

What was your last stable oc? Just these:
Multi:
Cpu Freq:
vcore:
cpu term:
MCH Core:

Have you had that 471 fsb stable before or is this the first time you are trying it?

You have some serious drop (Idle 1.32v Load 1.25v) without LLC, have you considered using it..?

The reason I ask about the fsb is because it's a good idea to find your highest stable fsb (lowering the multi) then going from there.

Multi: 8.5x (default for Q9550)
Cpu Freq: 3.92GHz
vcore: 1.3125
cpu term: 1.30
MCH Core: 1.30

Have you had that 471 fsb stable before or is this the first time you are trying it? No...have been trying for a few days with no luck

You have some serious drop (Idle 1.32v Load 1.25v) without LLC, have you considered using it..? Yes but voltage spikes scare me

The reason I ask about the fsb is because it's a good idea to find your highest stable fsb (lowering the multi) then going from there.

Should I go into windows with 6x multi and run large fft's to test? Or is the windows version of memtest better? Should I just leave all other settings (vcore etc) where they are and just change the multi?

pdawg17 · 08-04-09

CPU term at 1.32 failed after first run of Linx...I will run prime95 from now on (high temps) and that failed during test #2 of large fft...I will try LLC enabled but what voltage should I try? If it helps my 3.92GHz stable is set at 1.3125...

Try this look:

Fine CPU Clock Ratio.....................: +0.0
CPU Frequency ...........................: 4.00GHz (450x9)

CPU Host Clock Control..................: [Enabled]
CPU Host Frequency (Mhz) ............: [450]
PCI Express Frequency (Mhz) .........: [100]

Voltage Type.………... Manual
LLC............................................:[Enabled]
CPU Vcore….……….........................:<--- whatever gives 1.32 in CPU-Z

CPU Termination…..... [1.30]

CPU PLL…………………....[1.55] (default for my board)

CPU Reference.…………....[.838]

CPU Reference2………Not available on my board

MCH Core…………….....[1.26 maybe 1.28]<--This should be plenty
MCH Reference….…….[.835]
MCH/DRAM Ref.…......Not available
ICH I/O……………….....[1.500]
ICH Core…………...……[1.100]

Like NoGuru said, as long as you are below 1.4 you should be fine with LLC enabled. If your voltage was high we wouldn't tell you to use it.

When you enable LLC be sure and lower your vcore also. Start writing down what your voltage is in bios and in CPU-Z with LLC enabled like this bios/CPU-Z. So lower the vcore with LLC enabled and try to get 1.32v in CPU-Z.

Use small ffts in Orthos or in Prime 95. But you will have to let them run for at least 10 hours. This will really dig deep and find errors a linpack test (Linx/IBT) wouldn't, plus those high temps should drop a bit. And it's really necessary for a stable cpu oc. Try and stay below 70c.

Start at 1.32v in CPU-Z and run a small fft test. If it fails bump the vcore up one notch. But I think LLC will get you passed the hump. Your voltage was dropping pretty badly there without it.

It's getting late though. I'm off to bed for tonight.

The other guys here are past 4GHz so if they are around they'll be sure and help you out bro.

Just remember to try and keep your RAM as close to stock as possible for now. Get the cpu oc stable with small ffts and you can do the RAM/MCH after with a blend test.

I'm just really sleepy now.

Good luck.

*Edit: you want the cpu term like 2 notches below the vcore.

What is LLC?
Also, what do you think of these settings? good for 3.6ghz?
vcore 1.52500v (in windows 1.376v)
MCH 1.26v
cpu term 1.5 (i think its term lol)
FSB 400x9
memory 400, 1:1 ratio (stock)

NoGuru · 08-04-09

LLC is load line Calibration. It's in your bios. Those numbers are out of wack. Why don't you let us help you with your OC Bradley sound good?
