    Memory Upgrade causes Kernel Panic

    I have 16.04 LTS AMD64 on an older AMD64 processor the software is up to date as of yesterday. The Motherboard has 4 memory slots each of which can take 1GB. I had 2 GB in it. I added 2 more GB if identical memory (same brand Kingston and part number) now the system won't boot. The POST memory check passes. During the boot process I get a kernel panic, although not the same on each time.

    It is not the memory, the system will boot properly with either set of memory in either pair of slots. I also have tried using 2 1GB sticks with 2 256MB sticks I happen to have and that works properly. I have tried booting using mem=2G in the boot command line, that has no effect.

    Possibly some of the boot parameters might help but I'm not sure which to try.

    Run memtest to be sure about the RAM. POST misses a lot.
    If one RAM stick comes up bad, trade slots to determine if the culprit is bad RAM or a bad slot.

    Also try putting the new sticks in the first 2 slots and the older in the last 2. Or if you already had it that way, reverse it.

    I have a computer here that will only function with up to 3 gig in it. It is supposed to take up to 64 gig. 3 or less and all is well. Go over 3 g in any way and it won't work. You may have a bad board or CPU.

    Already tried that. Moved them around in every possible combination. any two will work all 4 in any configuration won't.

    You just may have the same problem as this one that I have. At this point, with everything that you tried, I do not believe it to be a memory stick problem but rather a mobo or CPU issue.

    Have you tried 3 sticks in any positions? My old single core early Athlon64 3200+ (2 GHz) supposedly used a method to access 2 chunks of memory in each cycle without using the dual-channel method that Intel uses. It was finicky about RAM at first. I bought some OCZ PC-3200 RAM on sale that would sort of work for a while in Linux, but not very long in Windows. OCZ told me they would send me RAM that they guaranteed would work, and it did. Many years later when I upgraded RAM I got PNY RAM and it simply worked.

    I have not had an AMD desktop since then, so I do not know if newer ones work fastest with matched pairs of RAM or would work as well with 3 slots filled.

    Yes.
    It would not recognize the 3rd stick but it worked showing 2GB. I also tried some 256MB sticks I had and they worked. I can use 2 1GB sticks and 2 256MB and get 2.5GB. I'd try some 512 Sticks but that I don't have any.

    I also swapped the CPU for an identical one with the same result.

    I think I have some other stick of a different brand. I'll try those next.

    Sounds like MOBO is going south on you.
