MacBookPro 3,1 - Kernel Panic situation

[BillieG]

I have a MacBookPro 3,1 (17 inch - 2.4 Ghz) model.
Processor: 2.6 Ghz Intel Core 2 Duo
Memory: 4 GB 667 MHz DDR2 SDRAM
Graphics: NVIDIA GeForce 8600M GT 128 MB
Running OS X El Capitan version 10.11.6
Due to overheating problems melting the solder points of the 256MB graphics card on the motherboard, we used an outside vendor to repair, they replaced the 256mb graphics chip with a 128mb graphics chip.
Except for the erratic kernel panics, which now happens about every month, the system works and performs good.
I did a clean reinstall of the OS, reset NVRAM(PRAM) and SMC, did disk checks, and I am trying to do an AHT which is scary as I do not know how to get the right link to download the AHT for my system. I am just clueless about what to do next, as I do not know what the panic report really says and what it all means.
Maybe one of you knows how to interpret the panic report? Or what might be wrong with my system or OS?
Thank you for the help...
Billie

It's not a serial number. Put only F42388C8 in the everymac search and it does return the MBP3.1

F4238BC8 is the 2.2GHz model,I believe.Yours shows as the 2.6, as recorded in the report.

Thank you ab298!
Your response made me try this command:
ioreg -l | awk -F\" '/board-id/ { print $4 }' in the terminal and it gave me the F42388C8.
I was using the wrong Hardware Test download!
Well, hopefully now it will work and I will maybe be able to see whether there is a hardware problem that causes it to crash once in a while.
Let's also hope that someone might just explain the Panic report to me... lol.
Thanks again from one MR newbie to another MR newbie ... :-D

I've seen suggestions that similar reports were due to a failing HD in conjunction with Time Machine backups; and others that did seem to be memory related.

Removing/cleaning/replacing both memory modules won't hurt. http://www.kelleycomputing.net/rember/
is more convenient & likely more thorough than AHT, albeit you would need to override the unidentified developer warning.

Thanks for that link ... I see that it can help me further troubleshoot ...
I was able to run the Apple Hardware Test, ran the AHT both the short and extended versions, each one pass, and no troubles were found.
Will try the other one now ... but at kelley computing I also read something about the ''Easy Sleep or Smart Sleep'' corrupt file... so I might try that one too ... and then I keep thinking about the graphic memory downgrade to 128MB.
Anyway, thank you so much for the help ...
Love & Peace
