Performance Injection: Socket 423 with 2.8 GHz

Upgrade With Phantom Processor

According to the Intel spec sheet, such a beast as a Pentium 4 with 2.8 GHz and 100 MHz system clock (FSB400) should not exist. But due to interest on the part of major customers, small batches like that are produced now and again, serving mainly upgrades - as is the case here.

...good Show!

Mission successful! Our test system started right up at 2.8 GHz - meaning it was both measurably as well as noticeably zippier.
