Yea, guide is helpful but confusing at points. Its all new!
If it does not post it is unstable clearly, but what we are looking for when we say stable is ~8hrs of prime. That ensures that your overclock wont randomly crash on a sudden increase in processor utilization.
Your Multiplier is locked, so raising the FSB is the way the overclock has to be done. To simplify the tutorial -
First step - Find Highest stable FSB
Set your Ram Ratio, NB multiplier, HT Multiplier to lowest , and cpu multitplier to lowest and take the FSB up from 200 about 6Mhz at a time- after each sucessfull boot, run 4-8 tests of prime, 5 - 10 minets worth, until you reach that place where its not passing the test. Once you reach that point change your CPU Vcore to about 1.44~1.53 and see if you can boot stable at the settings that where just unstable. If you can, go up to the next 6Mhz and again until you find your maximum stability below 1.55v. You will probably settle for a lower clock speed than your Max because who wants to run 1.5Vcore all the time? My guess is your Maximum will be between 250-255mhz on the Fsb.
Second step-Find Highest CPU Clock
bring the cpu multiplier up to 15X and repeat the steps of increasing voltage and prime testing. Once you reach the point where prime wont run for the few tests shoot a cpu validation and post it up as your max, then back off of that 10-16MHZ and attempt a longer stability test.
Third Step - Mix it all together
Bring your HT/NB and Ram Freq up. NB and HT should be around 2000Mhz and the Ram should be closer to 1333 than 1600 until stability can be confirmed. You may need to add voltage to the NB, just read closely as it will look like there are multiple places to do that in the voltage settings, just use the one that sayz NB voltage without much else.
Forth Step - Ram
You have already added voltage to the ram, that is good. During the OC process I would relax the timings to 9-9-9-24 with a 2t command rate. Don't worry about the long list of other settings for now, most of them can be left on auto and when you change the first 4 settings they will adjust accordingly.
Once you are finding stability with the CPU at the desired speed, and the HT and NB Frequency are high enough, then start raising the ram Freq. I would not suggest going over 1600Mhz, but as close to it as possible, then start bringing your timings down 1 point at a time, Stress testing after each setting for a few minuets.
Step Five - The big cooker
To ensure stability its best to do the Marathon test of 8 hours. If your not passing this test, raise voltages or drop Mhz.
My Guess is you will hit 3.6Ghz stable @ 1.53Vcore with your ram at 1600 Mhz. You will probably decide that that is too much voltage and drop back to 3.51 and @ 1.48Vcore and be happyish. I bet your maximum bootable is around ~3.75-3.82Ghz with the extra voltage of corse.
Here is a thread I did when I was overclocking the same set up.
