AMD Phenom II X4 840 overclocking guide solved
Guys, I'm using an AMD Phenom X4 840 with a 3.2ghz processor and wanted to push it up to at least 3.6ghz. I'm unsure how to configure it in the BIOS with MOBO MSI NF725m-P31. Do you have any advice or can you help me? Thanks!!
Adjust RAM speed slightly lower and configure PCIe at 100, since this increases with FSB as well; it helps prevent components from connecting to the PCIe bus (including SATA) too closely, which could cause instability.
The CPU's clock speed is set by the bus speed multiplied by the CPU clock multiplier. Because your CPU has a fixed multiplier, you can only decrease it; not raise it. Therefore, you should boost the bus speed, or FSB as shown in your photo. As you adjust this, all other components using the bus will also rise. It might be better to reduce your RAM clock speed to the next lower setting available, ensuring it doesn't fail first.
I attempted to raise the FSB Frequency to 240 and set the CPU ratio to "x15", which corresponds to 3600GHz, but the DRAM frequency also increased. I'm unsure how to reduce it. It now sits between 1400 to 1500MHz, and the remaining settings are in AUTO mode with a gray color setting that I can't modify.

My RAM speed adjustment should be found in the Cell Menu under Advanced Dram Configuration. What options appear when you press enter? Also, what is the original clock speed of your RAM? It seems to be 1333MHz.
