Methodology:
1. Always, Always have HWMonitor open on the desktop to monitor temps when stress testing. Don't allow TMPIN1 to exceed 65-70c. Don't allow TMPIN2 to exceed 85c.
2. Put CPU Clock Ratio to the stock 13.5 (since 13.5x200=2700 mhz).
3. Put CPU NB Freq. multiplier to 9x (10x is stock), i.e., you want to start it at 1800 mhz.
4. Put HT Link Freq. multiplier to 9x (10x is stock), i.e., you want to start it at 1800 mhz.
5. Put the Memory Clock to 800 mhz (3.33 to 1 ratio, I believe)
At this point you are asking, "Why is he having me set these frequencies lower than stock value when I am overclocking the system?" Answer: The CPU NB, HT Link and Memory frequencies are tuned to the CPU Frequency (aka, "FSB" and "HT Reference"). To overclock the CPU, you will be increasing the CPU Frequency. As you do, these other frequencies will increase along with it because they are tuned to the CPU Frequency, which is the master system bus. If these other frequencies exceed their stock values by very much they could cause instability and sabotage the effort to overclock the CPU. So you lower the frequencies of these other components to make headroom for overclocking the CPU.
6. Add .025 volts to the CPU voltage control.
7. Increase the CPU Frequency from the stock 200 to 205 mhz.
8. Run a 20 minute Prime95 blend test to check for stability and temps
9. If you pass the test in #8, increase the CPU Frequency to 210 mhz and retest.
10. Repeat the pattern in steps 7, 8 and 9, adding 5 mhz each tome to the CPU Frequency. When you first fail the test (blue screen, spontaneous restart, lockup or one of the Prime core workers drops out) roll back the CPU Frequency to the previous value used when the last Prime test was passed, rerun the Prime stress test and post back with attached pics of CPU-z tabs: CPU, Memory and SPD and of the HWMonitor interface so we can see what your bios values, frequencies and your max temps are looking like.
