I have a nice fast '486 clone. Unfortunately, when I activate the 128k  
external cache (as you all know, the 486 has an 8k onchip cache) I get
random lock ups with a memory parity error - address varies. After many
days of continuous ram testing and weeks of trouble free running without
the external cache enabled, I suspect that the 4mB of motherboard RAM is
quite healthy but that the parity error is arising from a flakey static
ram cache chip. So here's the rub - anyone written a pd or shareware 
cache tester ? Anyone up to the challenge ? Any thoughts on fixing this    
sucker ?
