Replacing an overclocked CPU?

[natty1]

Is it necessary to revert the current CPU to stock settings before replacing it with a new one?

i'm going e2160 to Q9650

Yes, you should set your CPU settings to default/auto in your BIOS. You don't want it to be applying voltages/frequencies/etc that you haven't tested with your new CPU (especially since you're going 65nm -> 45nm; you could end up badly overvolting your CPU).

What about FSB? The default FSB for e2160 is 200. The default for q9650 is 333. My current setting is 333. Can I leave it there? Or should I go back to 200 before popping in the quad?

Just boot up once and hit revert to defaults and save

Basically just turn off all manual adjustments and set everything to auto. The easier way is to just reset the bios to default completely.

There's that nifty option called "load optimized defaults" or something of the sort... it takes about 3 seconds to hit and it'll do everything for you.

I always clear the CMOS when changing CPU's

There's no need to clear the CMOS when changing CPUs. It only has to be done when updating to a newer BIOS.

I set the multi and FSB to the lowest possible to ensure an easy boot on the next chip.

u should always do a full cmos reset.

Oh really? Q9300.. *whistling*

*better run for provoking a senior moderator*

(it was actually my fault tho... lol. Lets just say gillbot wasnt expecting a quad)

I still did it, though as soon as it booted i set the fsb to 500 and the multi to 8 expecting to hit 4ghz on a E8500.

I also had issues going from a x3330 to a x6800 until i set the multi/fsb down.
