Ok, so my Phenom II 555 is now running stable at 3.9Ghz after solely adjusting the multiplier at 19.5x. At this speed, my CPU temp maxed at 37C while running Prime95 for hours. (Note: I am using a Tuniq Tower for cooling and at 20x mulitplier, the computer crashed.)
So, what is my next step? Should I increase the FSB or just increase the cpu voltage? I want to separately adjust RAM speed later if possible. Keep in mind that my MSI 890FX-GD70 has several options for adjusting voltages, so please be as descriptive as possible. I need precise steps towards achieving the maximum results. Any help is greatly appreciated.
I figured it out. However, at 19.5x multi I could run stock voltage of 1.375. In order to maintain stability at x20 multi I am running the voltage at 1.425 (Note: it crashed at 1.4 and 1.4125). Should I continue to push the voltage up or be happy with 3.9Ghz?
If you want keep the CPU for few years, I'd not go above 1.45V or 1.48V.
Regarding the BIOS, you only need rise this:
1- CPU voltage
2- CPU-NB voltage (If you changed the NB frequency, if not set to auto)
3- DRAM voltage (If you set the RAM timings manually)
4- NB voltage (If you change the NB frequency, if not set to auto)
I changed the CPU VDD voltage and this seems to have worked. I ran Prime95 for two hours at 20x multi and nothing crashed. Today I am running a 20.5x multi at 1.475. Hopefully this works. If I can get this to run 4.1Ghz I will be happy as it allows me to beat my friend who hates AMD's and spent 3x what I did to overclock a Core 2 Duo.
Ok, for some reason now everytime I run Prime95 I get the BSOD after about an hour. I am currently running a 20x multi at 1.463v. I've been upping the voltage everytime it happens. Should I keep moving it up. (Note: I am still under 40C.)
