Not sure how to increase the FSB speed.
Not sure how to increase the FSB speed.
I just purchased 1600 mhz ram and a motherboard that only supports 1333 mhz, but my RAM is downclocked to 533 mhz. The BIOS suggests adjusting the jumper if you use an FSB1333 CPU, which I did, yet it still doesn't let me set my RAM to 1333 mhz. I also can't find any way to overclock the FSB. I'm really new to all this.
FSB refers to the original designation for the processor's base frequency. Processor speed equals base frequency multiplied by the processor multiplier. I can't provide an exact figure without knowing your specific system type.
Your memory frequency is probably around 1066 MHz rather than 533 MHz, since DDR supports double data rate and you need to double it for full RAM speed. Adding the 533 read and 533 write operations results in a total of 1033 MHz.
Increasing the FSB will also allow overclocking the processor simultaneously (see the formula above). Going from 1066 to 1333 won't significantly improve performance. Memory also has its own multiplier, which is usually adjusted in the BIOS or via a jumper. This setting must be configured manually if the BIOS doesn't handle it automatically.

Memory also has its own multiplier, which is usually adjusted in the BIOS or via a jumper. This setting must be changed manually if the BIOS doesn't detect it automatically. This ensures only the memory frequency changes without overclocking the processor, which you might not wish to do or which may not be possible on your system.
CountMike explained the relationship between FSB, processor speed, and memory frequency. He noted that the processor speed equals the base frequency multiplied by the multiplier. He mentioned possible discrepancies due to system type and clarified that the memory frequency might actually be higher than 533MHz, likely around 1066 MHz considering DDR specifications. He also pointed out that increasing FSB could lead to processor overclocking, which may not be desirable or supported in some systems. Additionally, he mentioned that memory frequency adjustments usually require manual BIOS settings and cannot be automatically handled by the system.
