Experience I'm employed as a Systems Engineering Manager at All Covered with a specialty in Macintosh technologies. I'm an Apple Certified System Administrator (ACSA) through 10.4 and have the lower certs as well (ACTC for 10.1 - 10.5), an Apple Certified Help Desk Specialist for 10.3 (ACHDS) and a member of the Apple Consultants Network, as well as an Apple Product Professional for 2002-2007. I have an MCP cert. from MS as well... I've worked with the Macintosh Operating system and various machines since my first PowerMac 8500 running Mac OS 7.5.3 in 1996. I support my friends and family in keeping their Macs healthy and upgraded. Now I use a MacBook Pro for work and have a Flat Screen iMac (intel 20" core 2 duo) for home use. I went to school for multimedia and design, but this knowledge-base is fading, though I primarily geek out with workstation deployment and server management. I'm sort of a "Mac of all trades" :)
Most important: I've also worked on PCs for a number of years with various flavors of Windows(95,98,NT4,2000,2000Server,2K3Server,SBS 2K3Server,Mil,XPHome,XPPro, Vista Business), but I've always used the Mac as my platform of preference. Publications http://www.macwindows.com : VPNs and Outlook

2002 Power Mac G4 Dual 1GHz Quicksilver, 1.5 Gb, OSX 10.4.11
History: Mother or daughterboard (not sure which) was replaced 11 months into warranty period because of
similar problem (frequent crashes, panics). Eveything works great until a month ago.
Apple Hardware Test 1.2.4 has detected an error during startup. Logic Board: Error detected at startup.
**post/16/64** Quick & Extended Tests: passed all categories, including memory. System Profiler-->
Hardware--> Diagnostics--> Power On Self-Test: Failed Type: External Cache. "L3 cache" does not appear
anywhere in System Profiler. I don't recall ever seeing it there.
I removed the heat sink and cpu board and air-dusted entire area. Nothing looked unusual (to me). Also did
a logic board reset. Nothing any different. Performance and problem the same.
Where is the L3 cache physically located? There are two large Samsung chips soldered into the board near the
cpu's. If they're bad, should installing a new cpu card upgrade solve that problem? (btw, I didn't apply any
treatment to the cpu before i reattached the heat sink. is this dangerous?)
any advice appreciated. Thank you.

Answer Chris,
I actually don't know where the L3 cache is physically located. It's possible it's on the daughtercard; a good person to ask would probably be someone at Sonnet Tech or Newer, whomever you are thinking of using for a daughtercard replacement....
