I've got a question about why I when to adjust the FSB speed vs adjusting the CPU multiplier when overclocking.
I'm clear on what the two settings do to the hardware, but I'm not sure which adjustment would be better for performance.
I've noticed a lot of people (I'm referring to E6600s here) drop their CPU multipliers to hit high CPU OCs, but it seems to me that the extra FSB speed required to compensate for the decreased CPU multiplier would simply put extra stress on the mobo and possibly the memory.
Now I understand that if my FSB is 266 and I'm rocking some sweet low latency PC-6400 DDR2 I'll need to make some adjustments to either my FSB or my memory multiplier to get my memory running at its rated 800mhz and get the full bandwidth that I paid for.
But my noob-senses are telling me that E6600 at a 9x stock multiplier cranked to 400-fsb is the ideal setting as I can run my memory 1:1 at its lowest timings, whereas if I drop my multiplier to 7x I'd have to run @ 514fsb and then have to lock my memory at a lower speed or potentially run looser timings / put more stress on the mobo. (do high FSBs put more stress on the NB/mobo? or is CPU clock the more important variable)
Anyways, I'm sure I could figure it all out when my new system arrives but thought I'd farm it out for an expert opinion first.
I'm trying to wrap my head around this OC thing so bear with me.
Cheers
