What kind of CPU voltage you're using? I also want to know how much you needed to increase DRAM, NB voltage. List all possible voltages for me.

FSB termination voltage
NB Voltage
vCore
DRAM

TBH those are the things you really need. And NB on if you're going above the rated FSB.

I want to set all these. I want to see what voltages others are using. And I can do 4.2 GHz with 1.30V (bios).

TwoCables

With my particular E8400 on this particular motherboard with these particular components, I'm using the following:

• 1.312V core voltage (after vDrop - I have no vDroop)
• 1.30V FSB
• 2.175V VDIMM
• 1.45V NB
• 1.55V SB

However, even if I had the same exact rig that you have, your results could still be quite different. No two people should copy each others' settings.

Anyway, this overclock is stable enough to do the following:

• A little over 12 hours of the Small FFTs test (in Orthos/Prime95 - same thing, just a different GUI)
• About 7 hours of the Blend test
• Around 8 passes in Memtest (1 pass is when Memtest completes all 8 tests one time)
• 37 linpack runs using the maximum amount of memory

In other words, this overclock is rock-solid stable.

only changed cpu voltage, its now on 1.22v.
445x9=4ghz
stock cooler, stable occt, unless its a really hot day lol, im going to get a new cooler soon

I'm done editing. I'm sorry about my trigger finger.

You are using kind a high voltages. No heating problems with motherboard? And by the way, what is the maximum temperature for P5Q Pro to be on the safe side?

How about the timings for RAM? I want to run them under 5-5-5-10 or something but right now they are 5-5-5-12.

TwoCables

Are you referring to my VDIMM? I had to raise it that high so that I could lower my vcore and still be able to pass a ton of linpack runs. But thanks to my CM 690, I have a nice 120mm exhaust fan on the top right above my memory. So, going .075V over is just fine. Oh, my memory's voltage range is 2.0V - 2.1V.

But if I had problems with heat, then I wouldn't be so happy with this overclock.

Anyway, for the sake of stability, try to keep the CPU load temps under approximately 70°C or so. You know: somewhere in there. It's not like it's going to melt or die if the temps get to 75°C or even 80°C. But you could be frustrated by instability no matter what. However, with an adequate aftermarket CPU cooler with a proper application of some thermal compound, and adequate airflow in your case (which isn't disrupted by cables just hanging around), you should never ever have to worry about temnps - especially if you don't put the core voltage to more than like 1.362V (according to CPU-Z, as that's the actual voltage running through the CPU).

As for the RAM timings, that is, if you want to overclock the memory: the best thing to do with an Intel chipset, which is what you have (I have NVIDIA's nForce chipset), is to loosen the timings a little bit and then overclock the memory. Loosening the timings will allow you to overclock the memory. And then once you've settled upon a memory overclock, tighten the timings down on top of it. But if you had an nForce chipset like I do, then I would be giving entirely different advice from this.

Anyway, here are some tools that you need as an overclocker:

• Orthos - it's a stress tester. It's Prime95, but with a better GUI.
• LinX - it really is the best linpack tester available. Not even the latest version of Intel Burn Test can compare.
• Real Temp - it's the best temperature monitoring software.
• CPU-Z - this is an information tool
• Everest Ultimate Edition 4.60 - this is just a really cool piece of software, and it's free.
• Memtest86 - this is crucial for testing your memory, and it's totally free.
• Active@ ISO Burner 2.0 - this allows you to make a bootable disc of Memtest, which you have to do in order to use it.
• Real Temp's Documentation page (also known as the Installation & Calibration page) - this is some extremely valuable information that is vital to know. Read it carefully!
• ChickenInferno's thread called "TJ Max and Temperature Monitoring Programs" - this is some more extremely vital information. Read this carefully too!

That about covers it for now. But, I'll provide some more information later.

Edit: whoa. Nice avatar.

CPU can easily do over 4200 MHz and it looks like that my RAM can do 5-5-5-12 with 2.15V including a high frequency 450 MHz. I'm not sure could it handle 460-470 FSB too (means that CPU runs at 4.2 GHz) but I'm going to give it a try.

TwoCables

Just because it can do it, that doesn't mean it's stable. That's why I told you how stable my overclock is.

What voltages are you using to get over 4.200 GHz "easily"? What are the maximum load temps with the Small FFTs test? What is your CPU cooling solution? Which case do you have?
