fsb question

[pear]

I see alot of people with the same system are hitting 200fsb but I can't get over 175-180 without the computer rebooting and error messages.

I tried optimal and aggressive timings with the ram, but does not help, cpu interface enabled and disabled.

I started getting messages about checking hard drive and ran scandisk, everything is fine, if I lower fsb to 166, no message about hard drive.

I also recieved a serious error message has been detected with your software.

I have formatted the drive and reinstalled everything but still not running good. Any ideas would be welcome

Have you tried lowering the CPU's multiplier?

I lowered the multiplier to 10 and upped the fsb to 200 and it booted, no messages so far.
I feel pretty stupid for not thinking to lower the mutliper first, brain freeze LOL
