Howto stress the northbridge

[dermotti]

There any programs i can run that will work the northbridge hard and cause it to heat up? Orthos doesnt seem to do much to it.

I need something to run to verify that the northbridge is stable at full load when it gets really hot.

Basically, no.

But there are some things you can do.
On you using and amd or intel platform? There would be a big difference in how you go about doing these things. For intel, you just run some memory benchmarks. For AMD, you'd try to run something that moved a lot of data back and forth across video cards bus. Hmm, the only thing I can think of to do that would be to run the bitblit test in winbench.

There was a program that would stress it called BURNBX.

I don't know if it's available any more and if it even works with modern chipsets. In the 440BX era it most certainly did.

Intense graphic, and memory applications will use the northbridge.

Ayah, i think your right. I have one of ATI's graphic demos on loop and its heating up nicely.

Thx guys.

That's really not a very stressful situation at all. A modern 3d program will only issue geometry data and commands which do not saturate the pcie bus at all. Likewise, a normal program will use the cpu cache for 90%+ of its memory accesses and not stress the memory system anywhere near as much as a memory benchmarking program.
