NOPE. The PC164SX does not have L3 cache. That's why I bought a PWS to
replace mine. From the "AlphaPC 164SX Motherboard" User's Manual:
L1 Icache 16KB, direct-mapped, instruction cache on the CPU chip
L1 Dcache 8KB, direct-mapped, data cache on the CPU chip
L2 backup cache Onboard 1MB, direct-mapped, synchronous SSRAM
backup cache with 128-bit data path
