This is an interesting one from a PowerComputing Power Center Pro. According to PowerComputing its a 3.3V module so it won't work with other Macs, the Power Center Pro has a logic board jumper that allows the use of more standard 5V L2 cache modules. Also interesting is this module can operate on the Power Center Pro's 60MHz system bus.

Power Macintosh 4400/200
MacBench 4.0 test results. Spoiler, more L2 cache is generally better, but doesn’t hold a candle to G3 upgrades.

• Mac OS 8.6
• VM off
• Appletalk off
• 160GB PATA HD
• Sonnet G3 400/1MB L2 cache slot processor upgrade used for last test
