I have Cyrix 5x86-120 - I have not tried it at 3x33Mhz, but it works 
fine with fastest settings on ASUS PVI486SP3 with v3.04 BIOS and all 
settings at fastest and using Peter Moss 5x86.exe utility. At first I 
thought I might need faster cache, but in the end found out that if I 
used 8x32K L2 (15ns, 256K) everything would work fine at the fastest 
settings - With 4x64K or 4x8K or even 4x128K, the lack of interleaving 
requires slower settings or even no L-2 to get the system to be stable.
