Bluechip PowerBook G3 CPU Upgrade

Hardware Details:

Unlike the Newer Tech PB G3 CPU upgrades, the BlueChip is a newly manufactured module, not a rework of an existing one

  • IBM 500MHz Copper G3 CPU (revision 3.0)
  • 1MB of Sync. Pipeline Burst SRAM L2 Cache running 250MHz
    (review sample/demo would not run at 250mhz reliably, but retail models should)
    Cache Chips on this sample: Samsung K7A403600M-QC20 (x2) [200mhz rated]

Owners of the original PB G3/233 without backside cache the BlueChip upgrades should result in a very noticable performance boost. (With the backside cache, a G3 takes a 40% or so performance hit.)

Warranty: The BlueChip manual noted a 3 year limited warranty.


Compatibility: (repeated from the front page)

The Bluechip PowerBook CPU Upgrade is compatible with the following models:

1998 PowerBook G3 Series (Apple family number M4753):
