Quick Question

[Cheex]

Why do you lower the multiplier on some chips when you overclock?
What advantage or disadvantage does it have?


Example:
333 x 9 = 3GHz
375 x 8 = 3GHz

If seen many cases where people overclock and NOT use the highest possibly multiplier for a given chip.

Thanks in advance.

Clock speed is not everything.

Normally, the chip has separate limits on how fast its core can run and how fast a FSB speed it can handle. The core speed accounts for 95% of the performance, but once you've reached the core speed limit for a chip, you might as well boost the FSB (thus decreasing the multiplier to maintain the same top core speed) to eke out a few more percent performance.

That makes sense. Thanks.
