GT730 videocard freezes. What to do ?

[R.Wieser]

Hello all,

I've got a 'puter with a GT730 videocard in it, and, when displaying 3D
stuff (games but simple OpenGL stuff) it regulary locks up, resulting in a
"blue screen of death".

I've not changed the cards default settings, other than adjusting the
display dimensions.

According to the NVIDIA control panel I have the driver version 368.81,
which is the last one I can find. I did find quite a few posts about the
same problem, but no definitive solution.

the "Blue screen of death" data :

NV4_disp.dll

- Technical information
stop: 0x0000008E (0xC0000005 0xBD03D22A 0xB29FA548 0x00000000)

Adr:BD03D22A Base:BD012000


Does anyone have an idea how to tackle this ?

Regards,
Rudy Wieser

Is this a passively cooled card ?

If so, point a fan at the heatsink.

You should also have some means of reading out the GPU
temperature while your OpenGL code is running.

As I recollect, one of the lower end cards could be delivered
as a passive, and that one is likely to have a sink and fan because
of the higher power.

There's no point taking it all apart, without
a temperature measurement showing the temperature is
too hot. Try GPU-Z from techpowerup -- the dev uses
techpowerup as his dropsite.

If I'd used Furmark, then that gets the sensor hot enough
to speed up the fan. I was using SmokeParticle.exe, which is
only a half-load. I've probably got a Furmark on some
other partition, doesn't seem to be one here.

On one video card, I've had it apart to put fresh paste
on it. If there are four screw holes, you use two of
the (diagonal) screw holes as "sights" to check alignment,
when laying the card on top of the heatsink. Just about
all heatsink OPs like this make a mess, with stuff skating
around, and paste going all over the place. It helps to practice
assembly dry a number of times, until you have some idea
how much it is going to fight you. Some CPU heatsinks,
the screw engagement is terrible, and the screws just
never want to screw in. Needs nerves of steel.

Paul,

Sorry for the late response, I was a bit under the weather.

It is. And not even a big heatsink either.

I've bought a small fan and secured it ontop of the heatsink (sucking air
away from it).- I won't call it "screwed on", as I just wedged some screws
between the curved(!) blades of the heatsink

Lets see if it makes a difference.

By the way, I was completely focussed on a driver problem, and forgot all
about possible heat problems. :-| Thanks for reminding me. :-)

Long ago and with a different, more powerfull videocard I implemented some
code I found on the 'web. I've to dig it up and see if it works for this
card too.

Nice name. I remember a "nosmoke.com" driver from loong ago. According to
the story it didn't quite help putting the fire out. I hope yours doesn't
live up to its name either. :-)

I have no problem applying new paste on chips where the heatsink is stable
ontop of the chip (preferrably using a clip-on method), but have no wish to
gamble with the ones which play see-saw. For those I rather pay a
professional (read: having way more experience).
