  I'm running on Cyrix 486DLC-40 too.  I think your problem is arised by a
non-486DLC aware motherboard.  I am sure there is a program called cyrixtst
on which can detect such problem.  At least, mine is running
as fast as a 486DX-33 except FPU performance.  Of course, it should be much
nicer if I've more RAM but the price of DRAM here will kill me much. :)
