kernel panic

Dear sir,

So if i read it correct it could be a broken memory bar or a faulty. I removed the old ones and hot new ones in.

I really dont know much about the hardware part and al of those fault report, its like chinese to me. The strange thing is that the mac can for 5 days without any problem and then all of a sudden have a kernel panic 4 times in a row.

I want to thank you to the time and effort to help me.

iMac14,2, 24 GB RAM

" I removed the old ones and hot new ones in." I am not sure what this means(?)

Non the less it is classic example of faulty RAM your example above.

You are solving for both bad stick of RAM or a bad Bank.

Pull out one stick of RAM at a time and test. By deduction you are trying to find the bad stick or if all sticks seem good in one known good bank— try and isolate the bad bank and simply don't use it.

or if you narrow it down to a bad stick of RAM—you can replace it, or not, just remove it from the mix.

Macs always benefit from matched pairs— but not 100% necessary.

Best if you stay with high quality RAM from reputable source. You do want exact spec's for your machine.

Thanks Siggy69

Nothing has changed from my assessment above— Either one of the new RAM sticks is bad or one of the banks that it is inserted is bad.

You have to test for both, and it is a matter of elimination. There is no easier method, unless you take it in and have someone else do it for you.

Did you try and run the AHT test above as suggested? Did it kick out an error code.

good luck !

The Kernel Panic is incomplete—

If you have more than one Kernel panic, post at least three in their own Additional txt in their entirety

Good computing Siggy69 ! Thanks for your report.

I suspect from this non trend that you have a RAM hardware issue.

You can try running the Diagnostic/AHT  http://support.apple.com/kb/HT1509  may kick out an error code.

You can In or out of warranty you can get a free over the counter 'Apple Service Diagnostics' test / assessment
