A7N8X Deluxe with O/C XP 2400+

[John Saunders]

Hi,

I got my M/B a few weeks ago and have been
running my Athlon XP (TBred 2400+) with a
166MHz bus instead of the rated 133MHz. I
have read about people doing this with no
problems. However the computer has been a
tad flakey during this time. Since then I
have dropped the bus back to 133MHz and the
system has become rock stable being left on
24x7 without a crash.

I have PC3200 memory and want to run the FSB
as fast as possible. I know that my CPU won't
exceed 2000MHz without bumping Vcore above
1.65volts (1.75 gives me an extra 200MHz).
Is it necessary to bump up Vcore for the FSB
even if not overclocking the core?

If I get a 166MHz rated Barton, will it overclock
to 200MHz or will I have the same problem with
stability?

Thanks.

What multiplier are you using?

It shouldn't be necessary, but every system is different.

No guarantees that it would hit 200Mhz FSB. Newer low end Bartons are likely
to be multiplier locked. Unlikely to be worth the money.

15X with 133MHz and 12X with 166MHz to match 2GHz
that the core should handle.

It shouldn't be necessary, but every system is different.

Since I can't even POST with a 0.5X multiplier increase
without increasing Vcore I suspect I have a borderline
CPU.

I have just been reading about that. The best bet
appears to be a 2500+ with 11X multipler which would
give 2200MHz at 200MHz FSB. However I need better
cooling if I am going to wade out into the deep end
of the Vcore pool.

Thanks.

I have an XP2100 and PC3200 RAM. Best stable FSB is 180Mhz; highest
multiplier used is 12.5, with stock cooling.

I was contemplating a Barton 2500, but it does not seem to be worth it.

So it looks like a new graphics card instead...................
