Only first PIIs had L2 cache which was unable to store data located
beyond 512Mb memory boundary (233-300MHz, Klamath), and some of them
even didn't support ECC for L2 cache. All the next PIIs (333-450MHz,
Deschutes) had L2 cache with ECC, capable of all 4Gb. So PIIs are
not so bad as some people may think. Besides, L2 cache of PIIXeons
and some PIIIXeons (Drake & Tanner) is slow because it is off-core,
regardless of running at full core speed.
