I used that cooler before switching to my mugen 2. it served me rather well.

If you need any more information on specifically how to overclock on the p55 platform feel free to post back in this thread when you receive your cooler, or if you want to contact me directly you can send me a PM and I'd be more than happy to help you out.

I will most definitely take you up on that offer. If you don't mind, I could use that help now so that I know what to be doing once the fan arrives. I have a faint idea, but don't really know the proper way to go about it quite yet. Your help would save me a hell of a lot of time.

ooooooookay then, this is going to take me a bit. edit: that was a freaking workout for my fingers...lol

To start:

enter your bios and go to the area where you can change all of your CPU/memory settings such as vcore, bclk, pll, multiplier, etc. it's fine if you don't know exactly what all of these are and what they all mean for right now.

First of all, to eliminate all variable and ensure that you know exactly what your source of instability is, you will want to turn off EIST [speedstep], C1E, spread spectrum, LLC can go either way but I prefer to turn it off, at least at first, set your QPI ratio to as low as it goes, and your memory ratio to as low as it goes.

a few of these are temporary and you'll change them back and/or tweak them after we've tinkered some more, but for now you're just preparing yourself to mess with your CPU.

Next, scroll on down to your CPU vcore and just as a temporary safeguard, turn that up as high as you comfortably can, I try to stay always under 1.4v, but in your case I would probably set myself a ceiling of around 1.36-1.38 considering the cooling abilities of the zalman 9500.

I would set your cpu VTT to something around 1.25-1.3, probably on the lower end of that if you're only running 2 sticks of memory, on the higher end if 4.

DRAM voltage should be initially set at whatever your memory is rated at, provided that you are staying fairly close to what frequencies the memory is rated at when overclocking. NEVER raise your dram voltage above 1.65v.

Now that we've got ourselves a baseline for our OC, we can start messing with the actual cpu speeds.

You've got two important settings in this case, multiplier and baseclock [or bclk]. Your bclk is the base speed of the cpu and the multiplier is, as the name implies, the number this bclk is multiplied by to give us our actual CPU frequency.

To begin, and at your voltage "ceiling", I would aim for an OC around 3.7ghz to start with, and we can raise or lower that depending on what temperatures and voltages allow. An easy setting for this is to set your multiplier to 20, and your bclk to 185, this will net you a cpu speed of 3.7ghz even.

Before we stability test, scroll back down to your DRAM frequency. You will notice that this has almost surely changed. if your memory ratio is not at its lowest and your memory is at a speed that is way above what the memory is rated at [i.e. you have 1333mhz memory and it says the target frequency is 1850 or something], back down the memory multiplier so that the speed is either almost at or even below the speed your memory is rated at. this ensures that the memory isnt causing instability in your OC

Now you will want to save your settings and exit the bios, and boot up into windows. Once you're there, you'll need to grab a few programs. I would download intel burn test, prime 95, CPU-z, and coretemp.

once you've got them all installed, I would open up cpu-z, coretemp and intel burn to start doing some preliminary stability testing.

The reason I recommend you use IBT before P95 is that it is much much quicker to do a fast check to see if your settings aren't right, as you will usually see a BSOD/crash within a few minutes of IBT as opposed to 6-8 hours of P95, which is nice because it sucks to have to leave your computer idle for half a day only to find that your vcore is .02v too low and you have to try it all again.

Make sure CPU-Z is reporting all of the voltages and speeds properly, then open up IBT and coretemp. set memory to high and run it for 25 passes. Now for the first little bit, watch coretemp to make sure your CPU temperatures aren't getting to high. if they're going above 75 I would start to get uncomfortable, and over 80 i would stop the test and lower your CPU vcore and/or frequency to achieve lower temps. You should also watch cpu-z to make sure your voltages aren't dropping under or going over what you have set by a lot, because this generally means you're stressing your motherboards VRMs a lot to pump all that voltage through.

if you pass all 25 runs without problems, cpu vcore stays in check, and temperatures aren't too high, you can be fairly confident your CPU is stable. to be 100% sure, run 18+ hours of prime95 blend on all of your cores.

if after that you are still stable and temps are good, you can call it a day and be happy with your OC

if you crash but your temps are in check, lower your frequency. If your temps are really high but you don't have any crashes, lower both your vcore and your frequency a little bit. If your temps are bad and you crash, lower your frequency and your vcore until you achieve stability and good temperatures.

if you have any other questions feel free to ask.
