[QUOTE="heycatfish, post: 633500, member: 53207"] Hi, So i'm new here and i tried searching for my problem but i can't seem to find it. i apologize if i missed a huge thread about it. I bought a new macbook and gave my powerbook g4 to my mother. It had the 512mb ram original ram and i upgraded to 1gig of crucial ram. Since then the laptop will work for a while then either it will freeze, or an error that just says restart your computer will come up. when working on it the other day upon startup i got this error. System failure: cpu=0 code 00000008 (unaligned stack) Latest crash info for cpu 0 Exception state (sv=0x00001030) PC = 0x000ABC08 ; MSR=0x00001030; DAR=0x55555725; DSISR=0x42000000; LR=0x000ABACC; R1=0xFC14FB41; XCP=0x00000098 (system failure Backtrace: Backtrace terminated – unaligned frame address 0xFC14FB41 Proceeding back via exception chain Exception state (sv=0x3B4DE500) PC = 0x00002EF4 ; MSR=0x02003000; DAR=0x55555725; DSISR=0x42000000; LR=0x000029AC; R1=0xFC14FC21; XCP=0x0000000C (0x300 – Data access) Backtrace: Backtrace terminated – unaligned frame address 0xFC14FC21 Kernel version Darwin kernel version 8.11.0: Wed Oct 10 18:26:0 PDT 2007; Root:xnu-792.24.17 ~ 1/Release _PPC Memory access exception (1,0,0) Ethernet MAC address:00:00:00:00:00:00 ip address: 0.0.0.0 waiting for remote debugger connection It works sometimes then fails after its been on after a while. If i put the old ram it works fine. here is the ram i installed [url]http://www.newegg.com/Product/Product.aspx?Item=N82E16820145502[/url] i have read a lot about lower socket failure but it still reads as having 1 gig of ram so it reading both slots.. Specs Powerbook G4 1.25ghz originally 512rm running Tiger any ideas? Thanks from my mother and for the sake of phone bill cause she keeps calling me with questions! ;) thanks mac forums! kelly [/QUOTE]
