I've quite a hard time with my AMD 3500+ Winchester Core (Cpu-z shows revision dh8-d0).

As soon as I use up the available memory bandwith by memsetting a 1 meg buffer in a loop my system will hang.

So far I've already changed everything (from memory to psu to motherboard) except the cpu.

I can easily hang my system by running a little program like this (running under linux 2.6.x in either 32 or 64 bit mode):
int main(int argc, char *argv[])
char buf[1024*1024];
int i;
for (i=0;i<1024*16*8*8;++i)
return 0;

After about 1000 iterations in 64 bit mode and about 6-8000 in 32 bit mode my system will freeze.

This does not happen however if I add a slight delay into the loop or if I memcopy between two buffers.

So, after replacing almost all parts of my system I'd like to know if there possibly is a bug in my cpu version or what else I might try to change.

Currently I'm using an asus a8n-sli motherboard with 2 gigs of corsair memory.
The system is 100% stable during all normal operations, be it gaming in windows, compiling source for hours or whatever.

kind regards
