sandra and CPUz read the Data L1 cache as blank, its supposed to be increased compared to northwood, me thinks they may not have the right bios to turn it on. Did you notice the cpu 2003 benchmark of 12100 for the 2.8 prescott Vs. 8861 for the 3.2 pentium4 maybe CPU 2003 is independent of L1 and L2 cache, anyone known what a 3.2 athalon 64 scores on CPU 2003.
