TNT2, system locking up - even with slot fan

[Skeeter]

I thought I had all the bugs worked out
of my new system, but I've just noticed
that if I work the TNT2 card hard for
30-40 minutes or so, the system will
lock up. I have a BX Master mobo, P3-550
running at 733 Mhz, Guillemot Xentor 32
(TNT2) and a nice slot cooling fan right
under the TNT2. (the TNT2 has it's own
little cooling fan, too)

I'm running the latest Detonator drivers;
they solved a lot of game issues I had,
and they seemed to improve the stability
greatly. I just hadn't been using it
long enough to hit this new problem.

I thought I had the cooling issues covered.
The sytem temp. is 35-37(C) when I
reboot from a lock-up - not exactly
blazing...

Does anyone think I have a heat problem
here, or should I look elsewhere?

Any suggestions appreciated.

.5 volts might be a little too much. I think general guidance is to try to avoid raising the vcore more than 10%. Help me out if I'm all 8-up.

I think it was a typo as he knows his stuff...I recon he meant 0.05v but well spotted anyway.

[Skeeter]

The CPU voltage is set to 1.70. The mobo can
go from 1.65 to 2.4 in 0.05 increments.
(that must have been what he meant, right?)

Anybody think I should try 1.75?

Several issues could cause this, but is sounds more like a cpu problem. Are you renning the cpu at defualt voltage? If so, you might have to apply an extra .5v to gain system stablity. Also, how is your cpu temp? I assume since you have good case cooling that your cpu is cool as well.

Good question, it's been awhile since I
set up the CPU o/c. I'm not in front of
the system right now, so I'll have to
check on that one and report back.

Thanks,

Tried 1.75v, but that doesn't seem to
help. Instead of a lock-up, I get a
reset now. Normal operation is still
stable, but 20-30 minutes of Q3A and
I get a free reboot and disk check. ;-)

Any other suggestions?

Someone suggested
checking that the CPU is cooling well.
The temp. sensor is on the mobo and the
CPU is on a slotket, so I guess I better
make sure that it's cool enough.
