asus a7N8X-E Deluxe bios death?

[magus kent]

Just built one of these for my son for Christmas. 1 Gig (two sticks)
crucial 3200 or whatever it is thats supposed to run at 400MHZ, locked
Barton 2500+, 400 watt antec power supply, bios version is (I think) 1006,
etc. If I try to up the FSB over 180 the machine doesn't come back up and I
have to pull the power cord and use the jumper to reset to defaults. I
have a a7n8x deluxe revision 1.04 that I have no problem with 185 FSB.
Would get higher but have some cheap generic ram. THoughts on the new
machine? He was bummed when they locked the multipliers but I don't see
any reason why I shouldn't get 200 on the FSB. Temps are fine in the very
low 40's...thanks...m

The 2500+ has a FSB of 333(166), not 400(200).

Correct, Jason, but he/I would like to slightly overclock it, thus trying
to increase the FSB for a little more speed (he's into capping videos).
Thanks..m

Did you try raising the vcore up a step or two, not all chips will over
clock at their default voltage. I have a 2800+ barton and had to raise
it to 1.675v to run at 200x11. (default is 1.650v)

Cheers,

I have an Asus A7N8X with a 2500+ clocked at 11x200 FSB (Windows sees it as
a 3200+ ) ). To get there and remain stable I had to raise the Vcore to
1.70 Vdc. Anything less and it will crash out of CPU intensive tasks.

Try raising the Vcore slightly and then test with some flavor of 3DMark or
benchmark program. If it crashes try a slightly higher Vcore. Note: Ensure
you have a decent heatsink and fan as raising the Vcore WILL raise the CPU
temperature especially under heavy loads.

HTH.

The truth is out there. You just have to look in the right places and ask
the right questions.

Thanks, I'll give that a try next time I feel like messing with it..m

I'll do that. Just surprised that I'm having problems at that FSB
setting while my old a7n8x does fine at 180 with no other massaging
needed. thanks...m

A couple of things to keep in mind. Not all CPUs and RAM are created equally
which affects overclocking results either positively or negatively.

My first steps at overclocking my 2500+ showed me that it would go higher
but the RAM I was using just would not cooperate. I finally found a
reasonable price for some Kingston Hyperx modules. Since installing the
Hyperx RAM I have been able to overclock my 2500+ to 3200+ levels with no
difficulty. It might go somewhat higher but I'm happy with these results.

Thanks. I haven't tried changing the voltage yet, and if that doesn't
work then I can try my no-name ram in his machine, and if that works then
my son can see about RMS'ing the Crucial..m
